Abstract
Background: Vitamin D (vitD) plays a role in iron metabolism by the suppression of hepcidin, while iron deficiency also impairs vitD metabolism. In undernourished children, iron and vitamin D deficiency are common. There is little knowledge of the inter-relationship between these two nutrients in undernourished and non-undernourished children. Aim: To assess the association between 25-hydroxyvitamin D (25(OH)D) and iron status, and the effect of 3 doses of 50,000 IU of vitD on iron status in undernourished and non-undernourished children. Methods: We measured serum 25(OH)D, haemoglobin (Hb), ferritin and soluble transferrin receptor in 121 undernourished and 51 non-undernourished children in clinics in the North-West Province of South Africa. Three doses of 50,000 IU/week of vitD was supplemented to children with suboptimal vitD levels. Results: The overall prevalence of suboptimal vitD concentration (25(OH)D
