Item Micronutrient status and its relationship with nutritional status in preschool children in urban Sri Lanka(HEC Press, Australia, 2015) Marasinghe, E.; Chackrewarthy, S.; Abeysena, C.; Rajindrajith, S.OBJECTIVE: To assess the micronutrient status and its relationship with nutritional status in preschool children. METHODS: In a cross sectional study, anthropometric data and fasting blood samples were obtained from 340 children attending preschool in urban Sri Lanka. Serum concentrations of vitamin D, parathyroid hormone, vitamin A, zinc and haemoglobin were measured. Z-scores of anthropometric indices of height-for-age, weight-for-age and weight-for-height were computed to evaluate the nutritional status. RESULTS: Prevalence of stunting, underweight, wasting and anaemia among children were 7.1%, 16.9%, 21.2% and 7.4%, respectively. Deficiencies of zinc and vitamin A occurred among 67% and 38% of children, respectively. Vitamin D deficiency (<10 ng/mL) and insufficiency (10-20 ng/mL) occurred in 5.0% and 29.1% of children, respectively, and12% had parathyroid hormone levels indicative of hypocalcaemia. Nutritional status was significantly correlated (p<0.05) with vitamin D status [height-for-age (r=0.10), weight-for-age (r=-0.18), weight-for-height (r=-0.12)], and with haemoglobin status [weight-for-age (r=0.11)]. Zinc and vitamin A levels were lower in severe stunting compared with normal height (p<0.05). Significant correlations (p<0.05) were observed between vitamin D and parathyroid hormone (r=-0.12) and between haemoglobin and vitamin A (r=0.01), zinc (r=0.02) and vitamin D (r=0.02) levels. CONCLUSIONS: In the surveyed population, zinc deficiency was high and to a lesser degree vitamin A deficiency and vitamin D insufficiency prevailed. The nutritional status of the children was related to vitamin D status and with haemoglobin status. Zinc and vitamin A levels were low in children with severe stunting. Vitamins A, D and zinc levels were associated with haemoglobin status.Item Micronutrient status of plantation workers in Sri Lanka during pregnancy and post partum(Wiley-Blackwell Pub. Asia, 1996) de Silva, L.D.R.; Athukorala, T.M.S.Iron, zinc and vitamin A status was assessed in 309 plantation workers during pregnancy and in a sub-sample of 108 subjects at 20 to 36 weeks postpartum and the birth weights of their newborn were noted. A significant positive correlation was noted between haemoglobin concentration at 10-26 weeks of gestation of anaemic mothers (n = 180) and birth weights of their new born. Depleted iron stores (serum ferritin < 12 micrograms/l) were noted in 33.3% of subjects at 10-26 weeks of gestation. There was no significant change in serum ferritin concentration at > 32 weeks of gestation. Iron deficiency persisted at 20-36 weeks postpartum. Marginal vitamin A deficiency was also noted, as, 46.2% and 15.6% of the subjects respectively, had low serum vitamin A levels in pregnancy and postpartum. Low serum zinc levels were noted only in pregnancy. Iron supplementation during pregnancy was only effective in preventing further deterioration in iron status and it should be continued for about 12 weeks after delivery
