What are the current states of indicators contributing to a comprehensive view of nutrition for health and development in United States of America? See national data below.
What does this indicator tell us?
At population level, the proportion of infants with a low birth weight is an indicator of a multifaceted public health problem that includes long-term maternal malnutrition, ill health, hard work and poor health care in pregnancy. Low birth weight is more common in developing than developed countries.
How is it defined?
Low birth weight has been defined by WHO as weight at birth of < 2500 grams (5.5 pounds).
What are the consequences and implications?
Low birth weight is caused by intrauterine growth restriction, prematurity or both. It contributes to a range of poor health outcomes: it is closely associated with fetal and neonatal mortality and morbidity, inhibited growth and cognitive development and chronic diseases later in life. Low-birth-weight infants are approximately 20 times more likely to die than heavier infants.

Anaemia has a wide variety of causes. Although iron deficiency is probably the commonest cause of anaemia, other causes include acute and chronic infections that result in inflammation and haemorrhages; deficiencies of other vitamins and minerals, especially folate, vitamin B12 and vitamin A; and genetically inherited traits, such as thalassaemia. Other conditions (malaria and other infections, genetic disorders, cancer) also play a role. The terms 'iron-deficiency anaemia' and 'anaemia' are often used synonymously, and the prevalence of anaemia has often been used as a proxy for iron-deficiency anaemia, although the degree of overlap between the two varies considerably from one population to another according to gender and age.
Anaemia is defined as a haemoglobin concentration below a specified cut-off point, which can change according to the age, gender, physiological status, smoking habits and altitude at which the population being assessed lives. WHO defines anaemia in children under 5 years of age and pregnant women as a haemoglobin concentration < 110 g/l at sea level. The finger-prick blood sample test is easy to administer in the field. The test could be easily integrated in regular health or prenatal visit to capture all women in reproductive ages, though cost of equipment may be prohibitive.
What are the consequences and implications?
Anaemia is associated with increased risks for maternal and child mortality. Iron-deficiency anaemia reduces the work capacity of individuals and entire populations, with serious consequences for the economy and national development. In addition, the negative consequences of iron-deficiency anaemia on the cognitive and physical development of children and on physical performance - particularly the work productivity of adults - are major concerns. The numbers are staggering: about 25% of the world's population are anaemic, many because of iron deficiency; in resource-poor areas, the number is frequently exacerbated by infectious diseases. Malaria, HIV/AIDS, hookworm infestation, schistosomiasis and other infections such as tuberculosis contribute to the high prevalence of anaemia in some areas.
The main risk factors for iron-deficiency anaemia include a low dietary intake of iron or poor absorption of iron from diets rich in phytate or phenolic compounds. Population groups with greater iron requirements, such as growing children and pregnant women, are particularly at risk. Overall, the most vulnerable, poorest and least educated groups are disproportionately affected by iron-deficiency anaemia.

Vitamin A deficiency results from inadequate dietary intake of vitamin A to satisfy physiological needs. It may be exacerbated by high rates of infection, especially diarrhoea and measles. It is common in developing countries but rarely seen in developed countries. Vitamin A deficiency is a public health problem in more than half of all countries, especially those in Africa and South-East Asia, most severely affecting young children and pregnant women in low-income countries.
Vitamin A deficiency can be defined clinically or subclinically. The stages of xerophthalmia [clinical spectrum of ocular manifestations of vitamin A deficiency, from the milder stages of night blindness and Bitot spots to the potentially blinding stages of corneal xerosis, ulceration and necrosis (keratomalacia)] are regarded both as disorders and clinical indicators of vitamin A deficiency. Night blindness (in which it is difficult or impossible to see in relatively low light) is one of the clinical signs of vitamin A deficiency and is common during pregnancy in developing countries. Blood concentrations of retinol (the chemical name for vitamin A) in plasma or serum are used to assess subclinical vitamin A deficiency. A plasma or serum retinol concentration < 0.70 µmol/l indicates subclinical vitamin A deficiency in children and adults, and < 0.35 µmol/l indicates severe vitamin A deficiency.
Night blindness is one of the first signs of vitamin A deficiency. In its more severe forms, vitamin A deficiency contributes to blindness by making the cornea very dry and damaging the retina and cornea. An estimated 250 000-500 000 vitamin A-deficient children become blind every year, and half of them die within 12 months of losing their sight.
Vitamin A deficiency also contributes to maternal mortality and other poor outcomes of pregnancy and lactation. Furthermore, it diminishes the ability to fight infections. Even mild, subclinical deficiency can be a problem, as it may increase children's risk for respiratory and diarrhoeal infections, decrease growth rates, slow bone development and decrease the likelihood of survival from serious illness.

This indicator allows an assessment of iodine deficiency at population level. Iodine is an essential trace element that is present on the thyroid hormones, thyroxine and triiodotyronine. It occurs most frequently in areas where there is little iodine in the diet-typically remote inland areas where no marine foods are eaten.
The median urinary iodine concentration is the main indicator of iodine status in all age groups, because its measurement is relatively non-invasive and easy to perform. Goitre assessment by palpation or ultrasound may be useful for assessing thyroid function, but the results are difficult to interpret once salt iodization programmes have started. The indicator is the median concentration of iodine in urine in a population of children aged 6-12 years. Adequate iodine nutrition is considered to pertain when the median urinary iodine concentration is 100-199 µg/l.
A median urinary iodine concentration in a population of < 100 µg/l indicates that the iodine intake is insufficient. When the median is < 20 µg/l, the population is described as having severe iodine deficiency; at 20-49 µg/l, the public health problem is moderate, and at 50-99 µg/l, the population has mild iodine deficiency. A population's median urinary iodine concentration should be at least 100 µg/l, with less than 20% of values < 50 µg/l. For pregnant women, the median urinary iodine should be 150-249 µg/l.
Iodine-deficiency disorders, which can start before birth, jeopardize children's mental health and often their very survival. During the neonatal period, childhood and adolescence, iodine-deficiency disorders can lead to hypo- and hyperthyroidism. Serious iodine deficiency during pregnancy can result in stillbirth, spontaneous abortion and congenital abnormalities such as cretinism, a grave, irreversible form of mental retardation that affects people living in iodine-deficient areas of Africa and Asia. Of even greater significance is the less visible, yet pervasive, mental impairment that reduces intellectual capacity at home, in school and at work. It is estimated that, in 2007, iodine deficiency was a public health problem in 47 countries, and 266 million (31.5%) school-age children and 2 billion people in the general population had insufficient iodine intake.

This indicator is used in the NLIS as a proxy for access to health services and maternal care.
The indicator gives the percentage of live births attended by skilled health personnel in a given period. A skilled birth attendant is an accredited health professional-such as a midwife, doctor or nurse-who has been educated and trained to proficiency in the skills needed to manage normal (uncomplicated) pregnancies, childbirth and the immediate postnatal period, and in the identification, management and referral of women and newborns for complications. Traditional birth attendants, whether trained or not, are excluded from the category of 'skilled attendant at delivery'.
In developed countries and in many urban areas in developing countries, skilled care at delivery is usually provided in health facilities. Births do, however, take place in various other appropriate places, from home to tertiary referral centres, depending on availability and need. WHO does not recommend a particular setting for giving birth. Home delivery may be appropriate for normal births, provided that the person attending the delivery is suitably trained and equipped and that referral to a higher level of care is an option.
All women should have access to skilled care during pregnancy and at delivery to ensure the detection and management of complications. One woman dies needlessly of pregnancy-related causes every minute, representing more than half a million mothers lost each year, a figure that has improved little over the past few decades. Another 8 million or more suffer life-long health consequences from the complications of pregnancy. Every woman, rich or poor, has a 15% risk for complications around the time of delivery, but almost no maternal deaths occur in developed regions. The lack of progress in reducing maternal mortality in many countries often reflects the low value placed on the lives of women and their limited role in setting public priorities. The lives of many women in developing countries could be saved by reproductive health interventions that people in rich countries take for granted, such as the presence of skilled health personnel at delivery.

What do these indicators tell us?
These indicators are the proportion of children aged 6-59 months who received one and two doses of vitamin A supplements, respectively.
How are they defined?
The indicators are defined as the proportion of children aged 6-59 months who received one or two high doses of vitamin A supplements within 1 year. Current international recommendations call for high-dose vitamin A supplementation every 4-6 months for all children between the ages of 6 and 59 months living in affected areas. The recommended doses are 100 000 IU for 6-12-month-old children and 200 000 IU for those aged 12-59 months.
Programmes to control vitamin A deficiency enhance children's chances of survival, reduce the severity of childhood illnesses, ease the strain on health systems and hospitals and contribute to the well-being of children, their families and communities. The 1990 World Summit for Children set the goal of virtual elimination of vitamin A deficiency and its consequences, including blindness, by the year 2000. The critical role of vitamin A for child health and immune function also makes control of deficiency a primary component of efforts to improve child survival and therefore of the achievement of the fourth Millennium Development Goal, a two-thirds reduction in mortality of children under 5 by the year 2015.
As there is strong evidence that supplementation with vitamin A reduces child mortality, measuring the proportion of children who have received vitamin A within the past 6 months can be used to monitor coverage with interventions for achieving the child survival-related Millennium Development Goals. Supplementation with vitamin A is a safe, cost-effective, efficient means for eliminating its deficiency and improving child survival.

Children aged 6-59 months receiving vitamin A supplements
These indicators are the proportion of children aged 6-59 months who received one or two doses of vitamin A supplements.
Estimates of vaccination coverage of children aged 1 year are used to monitor vaccination services, to guide disease eradication and elimination programmes and as indicators of health system performance.
Measles vaccination coverage is defined as the percentage of 1-year-olds who have received at least one dose of measles-containing vaccine in a given year. In countries that recommend that the first dose be given to children over 12 months of age, the indicator is calculated as the proportion of children under 24 months of age receiving one dose of measles-containing vaccine.
Measles is a leading cause of vaccine-preventable childhood deaths, and unvaccinated populations are at risk for the disease. Measles is a significant infectious disease because it is so contagious that the number of people who would suffer complications after an outbreak among nonimmune people would quickly overwhelm available hospital resources. When vaccination rates fall, the number of nonimmune persons in the community rises, and the risk for an outbreak of measles consequently rises.

This indicator reflects the prevalence of children who were given zinc as part of treatment for acute diarrhoea. Unfortunately, there are no readily available data on this indicator, which is maintained in the NLIS to encourage countries to collect and compile data on these aspects in order to assess their national capacity.
Whereas there is no internationally accepted indicator for zinc treatment of children with diarrhoea, it could be defined as the percentage of children under 5 years with acute diarrhoea who were given supplements of 20 mg zinc daily for 10-14 days or 10 mg/day for infants under 6 months.
Measures to prevent childhood diarrhoeal episodes include promoting zinc intake. Diarrhoeal diseases account for nearly 2 million deaths a year among children under 5, making them the second most-common cause of child death worldwide. The greater the prevalence of zinc supplementation during diarrhoea treatment, the better the outcome of treatment for diarrhoea.
WHO and the United Nations Children's Fund (UNICEF) recommend exclusive breastfeeding, vitamin A supplementation, improved hygiene, better access to cleaner sources of drinking-water and sanitation facilities and vaccination against rotavirus in the clinical management of acute diarrhoea and also the use of zinc, which is safe and effective. Specifically, zinc supplements given during an episode of acute diarrhoea reduce the duration and severity of the episode, and giving zinc supplements for 10-14 days lowers the incidence of diarrhoea in the following 2-3 months.
Currently no data are available.

These indicators are the percentage of population with access to an improved drinking-water source and improved sanitation facilities.
Improved drinking-water sources are defined in terms of the types of technology and levels of services that are likely to provide safe water. Improved water sources include household connections, public standpipes, boreholes, protected dug wells, protected springs and rainwater collection. Unimproved water sources are unprotected wells, unprotected springs, vendor-provided water, bottled water (unless water for other uses is available from an improved source) and tanker truck-provided water. 'Reasonable access' is broadly defined as the availability of at least 20 litres per person per day from a source within 1 kilometre of the user's dwelling.
Improved sanitation facilities are defined in terms of the types of technology and levels of services that are likely to be sanitary. Improved sanitation includes connection to a public sewers, connection to septic systems, pour-flush latrines, simple pit latrines and ventilated improved pit latrines. Service or bucket latrines (from which excreta are removed manually), public latrines and open latrines are not considered to be improved sanitation.
Access to safe drinking-water and improved sanitation are fundamental needs and human rights vital for the dignity and health of all people. The health and economic benefits of a safe water supply to households and individuals (especially children) are well documented. Both indicators are used to monitor progress towards the Millennium Development Goals.

What does this indicator tell us?
This indicator reflects the percentage of women who were given supplements of both iron and folic acid during pregnancy. It would give information about the quality of and coverage of perinatal medical services. Unfortunately, there are no readily available data on this indicator, which is maintained in the NLIS to encourage countries to collect and compile data on these aspects.
How is it defined?
The current WHO recommendation is universal supplementation with 60 mg of iron and 400 µg of folic acid daily during pregnancy, as soon as possible after the beginning of gestation and no later than the third month and continuing for the rest of pregnancy. Whereas there is no internationally accepted indicator for these concerns, the indicator could be defined as the percentage of mothers who received daily iron and folic acid supplements for at least 6 months of pregnancy.
Improving the iron and folate intake of women of reproductive age could improve pregnancy outcomes and enhance maternal and infant health. Iron and folic acid supplementation can ensure the iron and folate status of women before and during pregnancy, in communities where food-based strategies are not yet fully implemented or effective. Daily dosing with folic acid before pregnancy during the first trimester of pregnancy decreases the risk for neural tube defects.
Anaemia during pregnancy places women at risk for poor pregnancy outcomes, including maternal mortality, and also increases the risks for perinatal mortality, premature birth and low birth weight. Infants born to anaemic mothers have less than one half the normal iron reserves. Morbidity from infectious diseases is increased in iron-deficient populations, because of the adverse effect of iron deficiency on the immune system. Iron deficiency is also associated with reduced work capacity and with reduced neurocognitive development.
Currently no data are available.

This indicator gives the prevalence of people living in extreme poverty, as measured by their daily income, and allows comparisons and aggregation of data on the progress of countries in reducing extreme poverty and allows monitoring of global trends.
The proportion of the population living on less than US$ 1 per day is the percentage living on less than US$ 1.08 a day at 1993 international prices. The US$ 1 per day poverty line is compared with consumption or income per person, including consumption of their own production and income in kind. As this poverty line has fixed purchasing power across countries or areas, it is often called the 'absolute poverty line'.
Purchasing power parity is defined by comparing economies on the basis of standardized international US$ price weights, rather than official currency exchange rates.
The US$ 1 per day poverty measure is used to assess and monitor poverty at global level, but, like other indicators, it is not equally relevant in all regions because countries have different definitions of poverty. Measures of poverty in countries are generally based on national poverty lines. Comparisons of poverty measures within countries are also difficult, especially for urban-rural differences. As the cost of living is typically higher in urban than in rural areas, the urban monetary poverty line should be higher than that for rural areas. The difference between the two in practice, however, may not properly reflect the difference in cost of living.
Malnutrition is the single one of the most important risk factor for disease. When poverty is added, it results in a downward spiral that may end in death.
Poor people may consume too little nutritious food, making them more susceptible to disease.
Inadequate or inappropriate food consumption leads to stunted development or premature death.
Nutrient-deficient diets provoke health problems.
Disease decreases people's ability to cultivate or purchase nutritious foods.

This indicator is the
percentage of the population whose food intake falls below the minimum level of
dietary energy requirements, and who therefore are undernourished or
The estimates of the Food and Agriculture Organization of the
United Nations (FAO) of the prevalence of undernourishment are essentially
measures of food deprivation based on calculations of three parameters for each
country: the average amount of food available for human consumption per person,
the level of inequality in access to that food and the minimum number of
calories required for an average person.
FAO improved the methodology used to estimate the prevalence of
undernourishment indicator, specifically:
a comprehensive revision of food availability data (including improved
estimation of food losses), improved parameters for dietary energy
requirements, updated parameters for food access and a new functional form for
the distributions used to estimate the prevalence of undernourishment. Some of the changes in the
revised estimates of undernourishment from 1990 to 2012 published in the State of
Food Insecurity in the World 2012 pertain to regular data updates carried out
almost every year (population estimates, revision of food availability data),
while others are the outcome of intensive efforts, aimed at substantially
improving the methodology currently used.
average amount of food available for human consumption is derived from national
'food balance sheets' compiled by FAO each year, which show how much of each
food commodity a country produces, imports and withdraws from stocks for other,
non-food purposes. FAO then divides the energy equivalent of all the food
available for human consumption by the total population, to derive average daily
household surveys are used to derive a coefficient of variation to account for
the degree of inequality in access to food. Similarly, because a large adult
needs almost twice as much dietary energy as a 3-year-old child, the minimum
energy requirement per person in each country is based on age, gender and body
sizes in that country.
The minimum dietary
energy requirement is derived from the results of a FAO/WHO/United Nations
University expert consultation in 2001 (published in 2004), which established
energy standards for different sex and age groups performing sedentary physical
activity and with a minimum acceptable body weight for attained height.
average energy requirement is the amount of food energy needed to balance
energy expenditure in order to maintain body weight, body composition and
levels of necessary and desirable physical activity consistent with long-term
good health. It includes the energy needed for the optimal growth and
development of children, for the deposition of tissues during pregnancy and for
the secretion of milk during lactation consistent with the good health of the
mother and child. The recommended level of dietary energy intake for a
population group is the mean energy requirement of the healthy, well-nourished
individuals who constitute that group.
reports the proportion of the population whose daily food intake falls below
that minimum energy requirement as 'undernourished'. Trends in undernourishment
are due mainly to:
in food consumption as reported on country food balance sheets;
in the distribution of dietary energy consumption in a population due to
changes in the distribution of both dietary energy consumption by income level
and dietary energy requirements based on weight for attained height by gender
and age; and
in the minimum dietary energy consumption due to changes in attained height and
the gender-age population structure.
indicator is a measure of an important aspect of food insecurity in a
population. Sustainable development requires a concerted effort to reduce
poverty, including solutions to hunger and malnutrition. Alleviating hunger is
a prerequisite for sustainable poverty reduction, as undernourishment seriously
affects labour productivity and earning capacity. Malnutrition can be the
outcome of a range of circumstances. In order for poverty reduction strategies
to be effective, they must address food access, availability and safety.

Salt iodization has been adopted as the main strategy for eliminating iodine-deficiency disorders as a public health problem, and the aim is to achieve universal salt iodization. While other foodstuffs can be iodized, salt has the advantage of being widely consumed and inexpensive. Salt has been iodized routinely in some industrialized countries since the 1920s. This indicator is a measure of whether a fortification programme is reaching the target population adequately.
The indicator is a measure of the percentage of households consuming iodized salt, defined as salt containing 15-40 parts per million of iodine. Preferably, household access to iodized salt should be greater than 90%.
Iodine deficiency is most commonly and visibly associated with thyroid problems (e.g. hyper- or hypothyroidism, goitre or an enlarged thyroid gland) but takes its greatest toll in impaired mental growth and development, which contribute to poor school performance, reduced intellectual ability and impaired work performance.
Consumption of iodized salt increased in the developing world during the past decade: in the early 1990s, only about 20% of households consumed adequately iodized salt, but today 68% of households do so. This means that about 84 million newborns are now being protected from learning disabilities due to iodine-deficiency disorders.

To enable mothers to establish and sustain exclusive breastfeeding for 6 months, WHO and UNICEF recommend:
· initiation of breastfeeding within the first hour of life;
· exclusive breastfeeding, i.e. only breast milk with no additional food or drink, not even water;
· breastfeeding on demand, as often the child wants, day and night; and
· no use of bottles, teats or pacifiers.
The recommendations for feeding infants and young children (6-23 months) include:
· continuing breastfeeding;
· introduction of solid, semisolid or soft foods at 6 months;
· appropriate food diversity (at least four food groups per day);
· appropriate frequency of meals: two to three times a day between 6 and 8 months, increasing to three to four times a day between 9 and 23 months with nutritious snacks offered once or twice a day, as desired;
· safe preparation of foods; and
· feeding infants in response to their cues.
The caring practice indicators for infant and young child feeding available on the NLIS country profiles include:
Early initiation of breastfeeding
This indicator is the percentage of infants who are put to the breast within 1 hour of birth.
Early initiation of breastfeeding is defined as the proportion of children born in the past 24 months who were put to the breast within 1 hour of birth.
Breastfeeding contributes to saving children's lives, and there is evidence that delayed initiation of breastfeeding increases their risk for mortality.
Infants under 6 months who are exclusively breastfed
This indicator is the percentage of infants aged 0-5 months who are exclusively breastfed.
It is the proportion of infants aged 0-5 months who are fed exclusively on breast milk.
Exclusive breastfeeding is an unequalled way of providing the ideal food for the healthy growth and development of infants; it is also an integral part of the reproductive process, with important implications for the health of mothers. An expert review of evidence showed that, on a population basis, exclusive breastfeeding for 6 months is the optimal way of feeding infants.
Breast milk is the natural first food for infants. It provides all the energy and nutrients that the infant needs for the first months of life. It continues to provide up to one half or more of a child's nutritional needs during the second half of the first year and up to one third during the second year of life.
Breast milk promotes sensory and cognitive development and protects the infant against infectious and chronic diseases. Exclusive breastfeeding reduces infant mortality due to common childhood illnesses, such as diarrhoea and pneumonia, and leads to quicker recovery from illness.
Breastfeeding contributes to the health and well-being of mothers, by helping to space children, reducing their risks for ovarian and breast cancers and saving family and national resources. It is a secure way of feeding and is safe for the environment.
Infants aged 6-8 months who receive solid, semisolid or soft foods
The indicator is the percentage of infants who start solid, semisolid or soft foods at between 6 and 8 months of age. WHO recommends starting complementary feeding at 6 months of age.
It is defined as the proportion of infants aged 6-8 months who receive solid, semisolid or soft foods.
When breast milk alone no longer meets the nutritional needs of the infant, complementary foods should be added. The transition from exclusive breastfeeding to family foods, referred to as 'complementary feeding', typically occurs between 6 and 18-24 months of age. This is a very vulnerable period, and it is the time when malnutrition often starts, contributing significantly to the high prevalence of malnutrition among children under 5 worldwide.
Children aged 6-23 months who receive a minimum acceptable diet
This indicator is the percentage of children aged 6-23 months who receive a minimum acceptable diet
The composite indicator of a minimum acceptable diet is calculated from:
· the proportion of breastfed children aged 6-23 months who had at least the minimum dietary diversity and the minimum meal frequency during the previous day and
Dietary diversity is present when the diet contained four or more of the following food groups:
· grains, roots and tubers;
· legumes and nuts;
· dairy products (milk, yogurt, cheese);
· flesh foods (meat, fish, poultry, liver or other organs);
· vitamin A-rich fruits and vegetables; and
· other fruits and vegetables.
The minimum daily meal frequency is defined as:
· twice for breastfed infants aged 6-8 months,
· three times for breastfed children aged 9-23 months and
· four times for non-breastfed children aged 6-23 months.
A minimum acceptable diet is essential to ensure appropriate growth and development for feeding infants and children aged 6-23 months. Without adequate diversity and meal frequency, infants and young children are vulnerable to malnutrition, especially stunting and micronutrient deficiencies, and to increased morbidity and mortality.

This indicator is the prevalence of children with diarrhoea who received oral rehydration therapy and continued feeding.
It is the proportion of children aged 0-59 months who had diarrhoea and were treated with oral rehydration salts or an appropriate household solution and continued feeding. The terms used for diarrhoea should cover the expressions used for all forms of diarrhoea, including bloody stools (consistent with dysentery) and watery stools, and should encompasses mothers' definitions as well as local terms.
Diarrhoeal diseases remain one of the major causes of mortality among children under 5, accounting for 1.8 million deaths among children worldwide. As oral rehydration therapy is a critical component of effective management of diarrhoea, monitoring coverage with this highly cost-effective intervention indicates progress towards the child survival-related Millennium Development Goals.

This indicator is the prevalence of women aged 15-19 years who are mothers or are pregnant with their first child. Adolescent pregnancies are still common, and WHO has identified the care of pregnant adolescents and the safe delivery and care of their infants as an area that was inadequately addressed. Adolescents account for 15% of the global burden of disability for maternal conditions and 13% of all maternal deaths.
Adolescent (or 'teenage') pregnancy is pregnancy at the age of 10-19 years. In most statistics, the age of a mother is defined as her age at the time her infant is born. Because there are considerable differences between 12- and 19-year-old girls and women, statistics are often presented separately for 10-14- and 15-19-year age groups. Birth rates and pregnancy rates are counted per 1000 of a specific population. Comparisons of country incidences are often given as rates per 1000 adolescents aged 15-19 years. The pregnancy rate includes pregnancies ending in births and those ending in abortion.
Births to girls and young women are strongly associated with health risks for both the mothers and the infants. Many of these risks are also associated with giving birth for the first time. Because adolescent mothers are usually also first-time mothers, it is difficult to separate these risks. For unknown reasons, the rate of death of adolescents in childbirth is disproportionately high; and adolescents are more likely to give birth to preterm and low-birth-weight infants, who are at higher risk for perinatal mortality. In many countries, the risk for dying from pregnancy-related causes is twice as high for adolescents aged 15-19 years as for older women.

Health expenditure includes that for the provision of health services, family planning activities, nutrition activities and emergency aid designated for health, but excludes the provision of water and sanitation.
Health financing is a critical component of health systems. National health accounts provide a large set of indicators based on information on expenditure collected within an internationally recognized framework. National health accounts consist of a synthesis of the financing and spending flows recorded in the operation of a health system, from funding sources and agents to the distribution of funds between providers and functions of health systems and benefits geographically, demographically, socioeconomically and epidemiologically.
General government expenditure on health as a percentage of total government expenditure is the proportion of total government expenditure on health. General government expenditure includes consolidated direct and indirect outlays, such as subsidies and transfers, including capital, of all levels of government social security institutions, autonomous bodies and other extrabudgetary funds.
Public expenditure on health is the total expenditure of all levels of government on health, presented as a proportion (%) of gross domestic product (GDP). It consists of recurrent and capital spending from government (central and local) budgets, external borrowings and grants (including donations from international agencies and nongovernmental organizations) and social (or compulsory) health insurance funds. GDP is the value of all final goods and services produced within a nation in a given year.
Per capita total expenditure on health is the sum of public and private health expenditure (in purchasing power parity, US$) divided by the population. Public health expenditure consists of recurrent and capital spending from government (central and local) budgets, external borrowings and grants (including donations from international agencies and nongovernmental organizations) and social (or compulsory) health insurance funds. Private health expenditure is the sum of outlays for health by private entities, such as commercial or mutual health insurance providers, non-profit institutions serving households, resident corporations and quasi-corporations not controlled by government involved in health services delivery or financing, and direct household out-of-pocket payments. Purchasing power parity is derived by comparing economies on the basis of standardized international US$ price weights, rather than official currency exchange rates.
These indicators reflect total and public expenditure on health resources, access and services, including nutrition. Although increasing health expenditures are associated with better health outcomes, especially in low-income countries, there is no 'recommended' level of spending on health. The larger the per capita income, the greater the expenditure on health. Some countries, however, spend appreciably more than would be expected from their income levels, and some appreciably less. When a government spends little of its GDP or attributes less of its total expenditure on health, this may indicate that health, including nutrition, are not regarded as priorities.

General government expenditure on health as a percentage of total government expenditure is defined as the level of general government expenditure on health (GGHE) expressed as a percentage of total government expenditure. The indicator contributes to understanding the weight of public spending on health within the total value of public sector operations. It includes not just the resources channelled through government budgets but also the expenditure on health by parastatals, extrabudgetary entities and notably the compulsory health insurance. The indicator refers to resources collected and pooled by public agencies including all the revenue modalities.
Total expenditure on health as a percentage of gross domestic product (GDP) is defined as the level of total expenditure on health expressed as a percentage of gross domestic product (GDP), where GDP is the value of all final goods and services produced within a nation in a given year. The indicator provides information on the level of resources channelled to health relative to a country's wealth.
Per capita total expenditure on health is defined as per capita total expenditure on health expressed at average exchange rate for that year in US$. The indicator contributes to understanding the total expenditure on health relative to the beneficiary population, expressed in US$ to facilitate international comparisons.
These indicators reflect government and total expenditure on health resources, access and services, including nutrition, in relation to government expenditure, the wealth of the country, and per capita. Although increasing health expenditures are associated with better health outcomes, especially in low-income countries, there is no 'recommended' level of spending on health. The larger the per capita income, the greater the expenditure on health. Some countries, however, spend appreciably more than would be expected from their income levels, and some appreciably less. When a government attributes less of its total expenditure on health, this may indicate that health, including nutrition, are not regarded as priorities.

This indicator describes the strength of nutrition in the United Nations Development Assistance Framework (UNDAF), the strategic programme framework for United Nations country teams. UNDAFs usually focus on three to five areas in which the country team can make the greatest difference, in addition to activities supported by other agencies in response to national demands but which fall outside the common UNDAF results matrix. For each national priority selected for United Nations country team support, the UNDAF results matrix gives the outcome(s), the outcomes and outputs of other agencies working alone or together, the role of partners, resource mobilization targets for each agency outcome and coordination mechanisms and programme modalities. The nutrition component of the UNDAF reflects the priority attributed to nutrition by the United Nations agencies in a country and is an indication of how much the United Nations system is committed to helping governments improve their food and nutrition situation.
The indicator is "strong", "medium" or "weak", depending on the degree to which nutrition is being addressed in the expected outcomes and outputs in the UNDAF. It been defined and estimated within the 'WHO Landscape Analysis', which is based on how the outcomes and outputs of the UNDAF address nutrition and the evidence-based interventions identified in the Lancet Nutrition Series (published in January 2008).
UNDAF documents follow a predefined format, with a core narrative and a results matrix. The matrix lists the high-level expected results ('the UNDAF outcomes'), the outcomes to be reached by agencies working alone or together and agency outputs. The results matrix the UNDAF document was used to assess commitment to nutrition, because it represents a synthesis of the strategy proposed in the document and is available in the same format in most country documents. The most recent UNDAF documents on the United Nations Development Group (UNDG) website were used. The outcomes and outputs specifically related to nutrition were identified and counted. The outputs were compared with the evidence-based interventions to reduce maternal and child undernutrition recommended in the Lancet Nutrition Series (Bhutta et al., 2008, Table 1, p. 42). The method and scoring are described in detail by Engesveen et al. (2009).
What are the implications?
A strong nutrition component in the UNDAF document means that the United Nations agencies consider nutrition to be a joint priority. A weak nutrition component in the UNDAF document does not necessarily imply that no United Nations agency in the country is working to improve nutrition; however, unless such efforts are mentioned in strategy documents like the UNDAF, they may receive inadequate attention from development partners to ensure the necessary sustainability or scale-up to adequately address nutrition problems in the country. The multisectoral nature of nutrition means that it must be addressed by a wide range of actors. Basing such action in frameworks for overall development contributes to ensuring the accountability of United Nations partners.

This indicator describes the strength of nutrition in the Poverty Reduction Strategy Paper (PRSP). The poverty reduction strategy approach was introduced in 1999 to empower governments to set their own priorities and to encourage donors to provide predictable, harmonized assistance aligned with country priorities. The PRSP should state the development priorities and specify the policies, programmes and resources needed to meet the goals. It is prepared by governments in a participatory process involving civil society and development partners, including the World Bank and the International Monetary Fund, and should result in a comprehensive, country-based strategy for poverty reduction.
The indicator is "strong", "medium" or "weak", depending on the degree to which nutrition is addressed in the PRSP, in terms of recognition of undernutrition as a development problem, use of information on nutrition to analyse poverty and support for appropriate nutrition policies, strategies and programmes. The indicator has been defined and estimated within the 'WHO Landscape Analysis' using a methodology proposed by the World Bank (Shekar and Lee, 2006). The most recent PRSPs available on the World Bank website were used. The papers were systematically searched for key words to identify the parts that concerned nutrition, food security, health outcomes and interventions that would be relevant for the World Bank method. In order to classify the commitments to nutrition in the PRSPs, a scoring system was developed, which is described in more detail by Engesveen et al. (2009).
The emphasis given to nutrition in PRSPs reflects the extent to which the government considers it essential to improve nutrition for poverty reduction and national development. In other words, it can be an indication of the government's priority for improving nutrition.
A strong nutrition component in a PRSP means that the government considers nutrition a priority for poverty reduction and national development. A weak nutrition component in the document does not necessarily imply that no government department is working to improve nutrition; however, unless such efforts are mentioned in strategy documents like PRSPs, they may not be sufficiently sustainable or be scaled-up to adequately address nutrition problems in the country. The multisectoral nature of nutrition means that it must be addressed by a wide range of actors. Basing such action in frameworks for overall development contributes to ensuring the accountability of relevant government departments.

This indicator is a description of the strengths and weaknesses of various aspects of nutrition governance in countries.
The nutrition governance score is "strong", "medium" or "weak", depending on the presence of a set of elements identified by countries themselves as crucial for successful development and implementation of national nutrition policies and strategies. The following 10 elements or characteristics are used to assess and describe the strength of nutrition governance:
· existence of an intersectoral mechanism to address nutrition;
· existence of a national nutrition plan or strategy;
· whether the national nutrition plan or strategy is adopted;
· whether the national nutrition plan or strategy is part of the national development plan;
· existence of a national nutrition policy;
· whether the nutrition policy is adopted;
· existence of national dietary guidelines;
· allocation of budget for implementation of the national nutrition plan, strategy or policy;
· regular nutrition monitoring and surveillance; and
· existence of a line for nutrition in the health budget.
These elements were identified by countries as key elements for successful development and implementation of national nutrition policies and strategies during a review of the progress of countries in implementing the World Declaration and Plan of Action for Nutrition adopted by the 1992 International Conference on Nutrition, the first intergovernmental conference on nutrition (Nishida et al. 2003). The method and scoring are described in detail by Engesveen et al. (2009).
The components of the composite indicator have been identified by countries as important for determining the completeness of national nutrition plans and policies (Nishida, Mutru, Imperial Laue, 2003). For instance, a national nutrition plan and policy was considered to provide the political basis for initiating action. In many countries, official government endorsement or adoption of a national nutrition plan or policy facilitated its implementation. The role of an intersectoral coordinating committee in implementing national nutrition plans and policies was also considered crucial, although the nature (i.e. whether executive or advisory), members, organizational structure and location of the committee determined its effectiveness. Another important element was considered to be regular surveys and other means of collecting data on nutrition. A periodically updated national nutrition information system and routinely collected data on food and nutrition were considered important for evaluating the effectiveness of national nutrition plans and policies and identifying subsequent actions.

This indicator provides information on national policies for legal entitlement to leave from work during pregnancy and after birth.
The indicator is the duration of maternity leave. The basic elements of maternity protection reflect concern to ensure the health of pregnant and nursing women and their children. They include the right to leave and to cash and medical benefits, so that before and after giving birth women workers can take a reasonable amount of time off, with sufficient continued income, to rest and recuperate, breastfeed and take care of their newly born children. The right to job security and nondiscrimination are other basic elements of maternal protection.
Governments have enacted a range of legislative measures to protect women workers during pregnancy and at childbirth. International labour standards have been established to provide maternity protection for women workers, including a new Convention and Recommendation adopted at the International Labour Conference in June 2000. The Maternity Protection Convention of the International Labour Organization (ILO) (C183) states that mothers should be entitled to a period of paid maternity leave of not less than 14 weeks, in addition to other benefits, including breastfeeding breaks and employment protection. The ILO Maternity Protection Recommendation (R191) recommends at least 18 weeks.
Appropriate maternity protection is a necessary condition for equality. More women are now in the labour force and work more continuously than before; they earn an increasing proportion of the family income and often work throughout their childbearing years. Exposure to certain health and safety hazards on the job or in the working environment during pregnancy can have adverse effects on the health of the woman and her unborn child. Before and after giving birth, she also needs a reasonable amount of time off from her job to recuperate, breastfeed and bond with her child. Many women want and need to be able to return to work after childbirth, and this is increasingly recognized as a basic right in a world where the participation of women in the labour force is approaching that of men in many countries. As many women support themselves and their families, continuity of income during maternity leave is vital.

This indicates whether a government has adopted legislation to monitor and enforce the International Code of Marketing of Breast-milk Substitutes, which helps create an environment that enables mothers to make the best possible feeding choice, based on impartial information and free of commercial influences, and to be fully supported in doing so.
This indicator is defined on the basis of whether a government has adopted legislation for effective national implementation and monitoring of the International Code of Marketing of Breast-milk Substitutes. The Code is a set of recommendations to regulate the marketing of breast-milk substitutes, feeding bottles and teats. The Code aims to contribute "to the provision of safe and adequate nutrition for infants, by the protection and promotion of breastfeeding, and by ensuring the proper use of breast-milk substitutes, when these are necessary, on the basis of adequate information and through appropriate marketing and distribution" (Article 1).
Improper marketing and promotion of food products that compete with breastfeeding often negatively affect the choice and ability of a mother to breastfeed her infant optimally. The Code was formulated in response to the realization that such marketing resulted in poor infant feeding practices, which negatively affect the growth, health and development of children and are a major cause of mortality in infants and young children.
Breastfeeding practices worldwide are not yet optimal, in both developing and developed countries, especially for exclusive breastfeeding under 6 months of age. In addition to the risks posed by the lack of the protective qualities of breast milk, breast-milk substitutes and feeding bottles are associated with a high risk for contamination that can lead to life-threatening infections in young infants. Infant formula is not a sterile product, and it may carry germs that can cause fatal illnesses. Artificial feeding is expensive, requires clean water, the ability of the mother or caregiver to read and comply with mixing instructions and a minimum standard of overall household hygiene. These factors are not present in many households in the world.

These indicators reflect the capacity of a country to train professionals in nutrition. As nutrition is an important part of health staff activities, adequate training of health professionals is essential to ensure that nutrition activities are part of the health system. Unfortunately, there are no readily available data on these indicators. The indicators are maintained in the NLIS to encourage countries to collect and compile data on these aspects in order to assess their national capacity.
The indicator ‘Density of trained nutrition professionals per 100 000 population’ reflects the capacity of a country to design and implement a nutrition policy and programmes effectively. Unfortunately, there are no readily available data on this indicator. This indicator is maintained in the NLIS to encourage countries to collect and compile data on these aspects in order to assess their national capacity.
What does the indicator tell us?
Nurse and midwife density indicates whether nurses and midwifery personnel are available to address the health care needs of a given population.
It is the number of nursing and midwifery personnel and density per 10 000 population. These personnel include professional nurses, professional midwives, auxiliary nurses, auxiliary midwives, enrolled nurses, enrolled midwives and other personnel, such as dental nurses and primary care nurses. Traditional attendants are not counted here but as community or traditional health workers.
There is no gold standard for a sufficient health workforce to address the health care needs of a given population. It has been estimated, however, that countries with fewer than 25 health-care professionals (counting only physicians, nurses and midwives) per 10 000 population fail to achieve adequate coverage rates for selected primary health care interventions that are priorities in the Millennium Development Goals.

Gross Domestic Product (GDP) per capita and GDP per capita annual growth rate are widely used by economists to gauge the health of an economy.
GDP per capita (purchasing power parity) is the GDP divided by the midyear population, where GDP is the total value of goods and services for final use produced by resident producers in an economy, regardless of the allocation to domestic and foreign claims. It does not include deductions for depreciation of physical capital or depletion and degradation of natural resources. Purchasing power parity indicates the rate of exchange that accounts for price differences across countries, allowing international comparisons of real output and incomes. The purchasing power parity US$ 1 has the same purchasing power in the domestic economy as US$ 1 in the United States. Purchasing power parity rates allow standard comparisons of real prices among countries, just as conventional price indexes allow comparisons of real values over time; use of normal exchange rates could result in over - or undervaluation of purchasing power.
GDP per capita annual growth rate is defined as the least squares annual growth rate, calculated from constant price GDP per capita in local currency units.
Higher income is usually associated with lower rates of malnutrition. Improving income however, reduces malnutrition to only a small degree (World Bank 2006). For example, when the gross national product [GDP plus the net factor income residents receive from abroad for factor services (labour and capital), less similar payments made to who contribute to the domestic economy] per capita in developing countries doubled, the nutrition situation did improve, but reductions in underweight rates were only modest-from 32% to 23%. On the basis of the correlation between growth and nutrition, it is estimated that a sustained per capita economic growth of 2.5% between the 1990s and 2015 would reduce malnutrition by 27%-only halfway towards the Millennium Development Goal target 3. These estimates suggest that countries cannot depend on economic growth alone to reduce malnutrition within an acceptable time.

Official development assistance received (net disbursements as a percentage of Gross Domestic Product (GDP)) is a measure of the flow of aid, private capital and debt in comparison with the value of goods and services produced within the country.
This indicator is official development assistance received as a percentage of the GDP. Net official development assistance consists of grants or loans to countries or territories from the official sector, with the main objective of promoting economic development and welfare, at concessional financial terms. GDP is the total value of final goods and services produced within a country's borders in a year, regardless of ownership.
When official development assistance makes up a large proportion of the GDP, a country is highly aid dependent, with the risk of unpredictable aid and donor-driven aid programmes. This can affect the resources allocated to nutrition, which are often not a donor priority in the sector-wide aid strategies promoted by the Paris Declaration (2005).

This indicator identifies countries with low income and food inadequacy.
A country is classified by the UN Food and Agriculture Organization (FAO) as 'low-income food-deficit' for analytical purposes on the basis of low income and food inadequacy, and the status is agreed by the country itself. The classification applies to countries that have a per capita income below the ceiling used by the World Bank to determine eligibility for International Development Association assistance and for 20-year terms determined by the International Bank for Reconstruction and Development, applied to countries included in World Bank categories I and II. The second criterion is based on the net (i.e. gross imports less gross exports) food trade position of the country, averaged over the preceding 3 years. Trade volumes of a broad range of basic foodstuffs (cereals, roots and tubers, pulses, oilseeds and oils other than tree crop oils, meat and dairy products) are converted and aggregated by the calorie content of individual commodities. The third criterion, which is self-exclusion, is applied when countries that meet the above two criteria specifically request to be excluded from the low-income food-deficit category. In order to avoid too frequent changes of low-income food-deficit status, usually reflecting short-term, exogenous shocks, an additional factor is taken into consideration. This factor, called 'persistence of position', postpones the 'exit' of a country from the list even if it does not meet the low-income or the food-deficit criterion, until the change in its status is verified for 3 consecutive years. In other words, a country is taken off the list in the fourth year after confirming a sustained improvement in its position. During these 3 years, the country is considered to be in a transitional phase.
The rationale behind the low-income food-deficit classification is that being both food deficit and having a low income at the same time means that the country lacks the resources not only to import food but also to produce sufficient amounts domestically. It is the combination of these two factors that makes these countries both food insecure and susceptible to domestic and external shocks, which could affect the nutritional status of vulnerable populations. The low-income food-deficit list is intended to capture this aspect of the food problem.
In comparison with countries in other classifications commonly used for analytical and operational purposes, e.g. 'least-developed countries', the World Bank's 'low-income countries' and 'heavily indebted poor countries', countries that are low-income food-deficit have demonstrated better nutrition and health related outcomes.

This is an indicator of gender equality and empowerment of women and reflects Millennium Development Goal 3, to promote gender equality and empower women. Women's representation in parliaments is one aspect of their opportunities in political and public life, and it is therefore linked to women's empowerment.
The proportion of seats held by women in national parliaments is obtained by dividing the number of parliamentary seats occupied by women by the total number of seats occupied. National parliaments consist of one or two chambers. For international comparisons, generally only the single or lower house is considered in calculating the indicator.
What are the implications?
Women are underrepresented in all decision-making bodies and political parties, particularly at the higher echelons. Women still face many practical obstacles to the full exercise of their role in political life. Low status restricts women's opportunities and freedom, giving them less interaction with others and fewer opportunities for independent behaviour, restricting the transmission of new knowledge and damaging their self-esteem and expression. It is a particularly important determinant of two resources for care: mothers' physical and mental health and their autonomy and control over household resources. Low status restricts women's capacity to act in their own and their children's best interests. There is a demonstrated association between women's status and malnutrition in children.

The world governance indicators of the World Bank Institute define governance as the traditions and institutions by which authority in a country is exercised. This includes the process by which governments are selected, monitored and replaced; the capacity of the government to formulate and implement sound policies effectively; and the respect of citizens and the state for the institutions that govern economic and social interactions among them. The world governance indicators measure six broad definitions of governance, capturing the key elements of this definition:
· Voice and accountability: the extent to which a country's citizens are able to participate in selecting their government, as well as freedom of expression, freedom of association and free media;
· Political stability and absence of violence or terrorism: the likelihood that the government will be destabilized by unconstitutional or violent means, including terrorism;
· Effectiveness: the quality of public services, the capacity of the civil service and its independence from political pressures and the quality of policy formulation;
· Regulatory quality: the ability of the government to provide sound policies and regulations that enable and promote private sector development;
· Rule of law: the extent to which agents have confidence in and abide by the rules of society, including the quality of contract enforcement and property rights, the police and the courts, as well as the likelihood of crime and violence; and
· Control of corruption: the extent to which public power is exercised for private gain, including both petty and grand forms of corruption, as well as 'capture' of the State by elites and private interests.
The averaged aggregate governance indicators in the NLIS country profile represent the aggregated average of the six world governance indicators. The indicators represent the views of thousands of stakeholders worldwide, including respondents to household and firm surveys and experts from nongovernmental organizations, public sector agencies and providers of commercial business information. The NLIS averaged aggregate governance indicators are calculated from the average of the z scores (a measure of standard deviations away from the mean) of the six world governance indicators. Each of the six indicators are expressed as the standard normal units, ranging from around -2.5 to 2.5. The higher the score a country has, the better the assessment has it received regarding the six governance elements.
Policy-makers, civil society groups, aid donors and scholars around the world increasingly agree that good governance affects development. This consensus has emerged from a proliferation of empirical measures of institutional quality and governance, the investment climate and research (World Bank Institute, 2008).
For nutrition, the importance of good governance is reflected in the UNICEF conceptual framework of factors in the "control and management of resources influenced by political and ideological structures in society'' (Jonsson 1995). The SCN 5th Report on the World Nutrition Situation (SCN 2004) further shows how a nutrition perspective can help improve governance. Good governance is also recognized by countries themselves in the Voluntary Guidelines to support the progressive realization of the right to adequate food in the context of national food security (FAO 2004) as an essential factor for sustained economic growth, sustainable development, the eradication of poverty and hunger and the realization of all human rights, including the right to adequate food.

does this indicator tell us?
The Gender Inequality Index (GII) provides insights into gender
disparities in health, empowerment and labour market. Unlike the HDI, higher
values of the GII indicate worse achievements.
The Gender Inequality Index is a composite measure reflecting inequality
in achievements between women and men in three dimensions: reproductive health,
empowerment and the labour market.
The health dimension
is measured by maternal mortality ratio and the adolescent fertility rate.
dimension is measured by the share of parliamentary seats held by each sex and
by secondary and higher education attainment levels.
The labour dimension
is measured by women's participation in the work force.
It varies between zero (when women and men fare equally) and one (when
men or women fare poorly compared to the other in all dimensions). The Gender
Inequality Index is designed to reveal the extent to which national human
development achievements are eroded by gender inequality, and to provide
empirical foundations for policy analysis and advocacy efforts.
Low status restricts women's opportunities and freedom, giving them less
interaction with others and fewer opportunities for independent behaviour,
restricting the transmission of new knowledge and damaging their self-esteem
and expression. It is a particularly important determinant of two resources for
care: mothers' physical and mental health and their autonomy and control over
household resources. Low status restricts women's capacity to act in their own
and their children's best interests. There is a demonstrated association
between women's status and malnutrition in children.

This indicator of gender equality is also an indicator of Millennium Development Goal 3: to promote gender equality and empower women.
The ratio of girls to boys, the gender parity index, in primary education is the ratio of the number of female students enrolled at the primary level of education to the number of male students. To standardize the effects of the population structure of the appropriate age groups, the gross enrolment ratio for each level of education is used. The gross enrolment ratio is the number of students enrolled in primary, secondary and tertiary education, regardless of age, as a percentage of the population of official school age for the three levels.

hunger index is a means of monitoring whether countries are achieving the
hunger-related Millennium Development Goals. It can be used for international
hunger index captures three dimensions of hunger: insufficient availability of
food, shortfalls in the nutritional status of children and child mortality,
which is to a large extent attributable to undernutrition. Accordingly, the
index includes three equally weighted indicators: the proportion of people who
are food energy-deficient, as estimated by FAO, the prevalence of underweight
in children under the age of 5 as compiled by WHO and mortality rate of
children under 5 as reported by UNICEF. In order to identify countries that are
notably better or worse off with regard to hunger and undernutrition than would
be expected from their gross national income per capita, a regression analysis
is made of the global hunger index on gross national income per capita. Countries
are ranked on a 100-point scale, with 0 and 100 being the best and worst
possible scores, respectively.
Hunger is one of the
world's major problems and therefore one of its most important challenges.
Hunger and undernourishment form a vicious circle, which is often 'passed on'
from generation to generation: The children of impoverished parents are often
born underweight and are less resistant to disease; they grow up under
conditions that impair their intellectual capacity for the whole of their life.
As of 2009, FAO estimates that 1.02 billion people are undernourished
worldwide. This is the highest number since 1970, the earliest year for which
comparable statistics are available.
factors that contribute to a high global hunger index are:
· Low income and
Countries with high hunger indexes are overwhelmingly low- or low- to
middle-income countries with high levels of poverty. Sub-Saharan Africa and
South Asia are the regions with the highest global hunger indexes and the
highest poverty rates.
· War and violent
These have been major causes of widespread poverty and food insecurity in most
countries with high global hunger indexes.
· General lack of
The 15 countries with the highest global hunger indexes were consistently rated
by the 'Freedom House Index' as non-free or partially free (with regard to
political rights and civil liberties) in the period 2006-2008.
· Women's status (in South
Asia): Low women's status is an important contributor to child malnutrition,
which in turn accounts for high global hunger indexes for South Asian
· Poorly targeted and
delivered health and nutrition programmes: Well-designed,
well-implemented health and nutrition services can reduce child malnutrition substantially.
Many of the countries with high global hunger indexes, especially in South
Asia, do not have effective health and nutrition services that reach the most
vulnerable age groups (pre-pregnancy through 2 years of age).

The human development index is a summary measure of human development.
The human development index is a summary composite measure of a country's average achievements in three basic aspects of human development: health, knowledge and a decent standard of living. It is a measure of the average achievements in a country in three dimensions of human development:
· a long and healthy life, as measured by life expectancy at birth;
· knowledge, as measured by mean years of schooling and expected years of schooling; and
· a decent standard of living, as measured by GNI per capita in purchasing power parity terms in US$.
The HDI sets a minimum and a maximum for each dimension, called goalposts, and then shows where each country stands in relation to these goalposts, expressed as a value between 0 and 1. The higher a country's human development, the higher its HDI value.
The human development index is used to capture the attention of policy-makers, the media and nongovernmental organizations and to draw it away from the usual economic statistics to focus on human outcomes. It was created to re-emphasize that people and their capabilities should be the ultimate criteria for assessing the development of a country, not economic growth.
The human development index is also used to question national policy choices, to determine how two countries with the same level of income per person can have widely different human development outcomes. For example, two countries may have similar income per person, but the life expectancy and literacy differ greatly, so that one of the countries has a much higher human development index than the other. These contrasts stimulate debate on government policies on health and education, to determine why what is achieved in one country is beyond the reach of the other.
The human development index is also used to highlight differences within countries, between provinces or states, across genders, ethnicity and other socioeconomic groupings. Highlighting internal disparities along these lines has raised national debate in many countries.
