Iodine deficiency disorders in the WHO African Region: Situation analysis and way forward
AbstractIodine deficiency disorders (IDDs) refer to a wide range of health problems associated with iodine deficiency in a population. These health problems include goitre, stillbirth, stunted growth (cretinism), thyroid deficiency and mental defects (impaired neurocognitive development), and are preventable by ensuring adequate intake of iodine. Pregnant women and young children living in IDD affected areas are particularly at risk. 2. Iodine deficiency is caused by low dietary intake of iodine. Populations living in areas where the iodine content in soil is depleted through repeated leaching by water and heavy rainfall are frequently affected. Crops produced on such soil have inadequate levels of iodine. 3. Iodine deficiency disorder is a public health problem in populations where the median urine iodine is less than 100 μg/l or where more than 5% of children aged 6 to 12 years have goitre. In areas of severe iodine deficiency, cretinism can affect 5% to 15% of the population and can cause a mean intelligence quotient loss of 13.5 points in the population.
