ABSTRACT
PIP: Deficiencies of either calcium or vitamin D can cause nutritional rickets. Findings are reported from a study conducted to assess the prevalence of vitamin D deficiency in young Nigerian children living in an area where nutritional rickets is common. A random sample of 218 children aged 6-35 months in Jos, Nigeria, was evaluated. The children were of mean age 22 months. No child had a 25-hydroxyvitamin D (25-OHD) concentration of less than 10 ng/ml, the generally held definition of vitamin D deficiency. Children spent an average of 8.3 hours/day outside of the home, and 20 children (9.2%) had clinical findings of rickets. Children with clinical signs of rickets were more likely to be not currently breast-fed and have significantly lower serum calcium concentrations than those with no signs of rickets. 25-OHD levels were not significantly different between children with clinical signs of rickets and those without such clinical signs. The failure to find vitamin D deficiency in this population of young children in whom clinical rickets is common is consistent with the hypothesis that dietary calcium insufficiency, without preexisting vitamin D deficiency, accounts for the development of rickets in Nigerian children.
