Effect of Ramadan fasting on glucose level, lipid profile, HbA1c and uric acid among medical students in Karachi, Pakistan
Khan, Nazeer; Rasheed, Abdur; Ahmed, Hassaan; Aslam, Faiza; Kanwal, Fatima ( 2017-04 )

To assess the effect of Ramadan fasting on blood pressure, fasting glucose, lipid profile, uric acid, HbA1c, body mass index, body adiposity index and visceral adiposity index among fasting medical students, 35 students were recorded before, during and after Ramadan [August] 2011, for their blood pressure, anthropometric measurements, questionnaire response and blood sample. A blood sample was taken at each visit for glucose, lipid profile and HbA1c. Total physical activity, weight-to-height ratio, body adiposity index and visceral adiposity index were calculated for insulin sensitivity. Changes in anthropometric measurements were not statistically significant. However, physical activities increased significantly after Ramadan. Changes in blood pressure, fasting blood sugar, total cholesterol, HbA1c, uric acid and triglyceride were not statistically significant. Mean high density lipoprotein decreased significantly in Ramadan, while low density lipoprotein increased significantly

Afin de mesurer les effets du jeûne du Ramadan sur la tension artérielle, la glycémie à jeun, le profil lipidique, l'acide urique, l'hémoglobine glyquée [HbA1c], l'indice de masse corporelle, l'indice d'adiposité corporelle et l'indice d'adiposité viscérale d'étudiants en médecine pratiquant le jeûne, 35 étudiants ont été évalués avant, pendant et après Ramadan [août] 2011. Leur pression artérielle a été contrôlée, les mesures anthropométriques ont été prises, un questionnaire leur a été remis et des analyses de sang ont été réalisées. Des prélèvements sanguins ont été effectués à chaque visite pour mesurer le glucose, le profil lipidique et l'HbA1c. L'activité physique totale, le rapport poids-taille, l'indice d'adiposité corporelle et l'indice d'adiposité viscérale ont été calculés pour déterminer la sensibilité à l'insuline. Les changements au niveau des mesures anthropométriques n'étaient pas statistiquement significatifs. En revanche, l'activité physique connaissait une nette augmentation après le Ramadan. Les changements au niveau de la pression artérielle, de la glycémie à jeun, du cholestérol total, de l'HbA1c, de l'acide urique et des triglycérides n'étaient pas significatifs d'un point de vue statistique. Les lipoprotéines de haute densité moyennes baissaient significativement pendant le Ramadan, au contraire des lipoprotéines de basse densité qui augmentaient considérablement

Effect of Ramadan fasting on secretion of sex hormones in healthy single males
Mesbahzadeh, B.; Ghiravani, Z.; Mehrjoofard, H. ( 2005 )

To determine the effects of Ramadan fasting on the secretion of sex hormones in single healthy males, we measured blood hormone levels of testosterone, luteinizing hormone [LH] and follicle-stimulating hormone [FSH] in 52 single male students aged 18-24 years who were fasting for >/= 12 hours during Ramadan. Four blood samples were taken from each, one 2 days before and the others on 10, 20 and 28 Ramadan. Testosterone level was lower, significantly so for the 20th and 28th of the month [P < 0.05]; FSH was increased, significantly for the 20th [P < 0.05]; LH did not change significantly

[Food intake, and anthropometrical and biological parameters in adult Tunisians during Ramadan]
Beltaifa, L.; Bouguerra, R.; Ben Slama, C.; Jabrane, H.; El Khadhi, A.; Ben Rayana, M.C.; Doghri, T. ( 2002 )

We evaluated the effects of fasting during Ramadan on nutritional intake and plasma lipoproteins in 20 healthy adults of normal weight. A 5-day food questionnaire was completed for every participant. Clinical investigations, anthropometrical measurements and laboratory analysis were also undertaken. Body weight, blood pressure and blood glucose were not influenced by fasting but there were non-significant modifications in the plasma lipid fractions. The total cholesterol remained unchanged. Total daily energy intake was comparable before, during and after Ramadan despite the decrease in meal frequency during fasting. Thus fasting in Ramadan did not affect dietary intake, clinical, anthropometrical and most biological parameters

Predicting serum gastrin levels among men during Ramadan fasting
Nomani, M.Z.A.; Khan, A.H.; Shahda, M.M.; Nomani, A.K.; Sattar, S.A. ( 2005 )

Increased gastric acidity is common when fasting during Ramadan. Our study aimed to develop a regression equation to predict fasting serum gastrin levels using parameters commonly analysed in clinical laboratories. Fasting blood samples from six men were taken on days 1, 10, 19, 26 and 28 of Ramadan. Serum gastrin, total cholesterol, urea and uric acid were analysed. All 5 samples from each man were included in multiple regression analysis and the prediction equation obtained was: serum gastrin, pg/mL = 198.27-0.199 total cholesterol [mg/dL] + 2.525 urea [mg/dL]--103.238 uric acid [mg/dL] + 10.923 uric acid [mg/dL]2 + 3.683 body mass index, r2 = 0.75, P < 0.001. This equation might be used to estimate gastrin levels and plan dietary and medicinal measures to avoid high gastric acidity during Ramadan
