Vitamin D supplementation has no effect on rickets or growth in stunted kids: Study
UK: Vitamin D supplementation has no effect on children with stunted growth or rickets except for those having high calcium intake, finds a recent study in the journal Pediatrics.
Vitamin D or sunshine vitamin is essential for healthy development of bones but not much is known about effects of vitamin D supplementation in young children with stunted growth. The aim of the study by Francesca L. Crowe, London School of Hygiene and Tropical Medicine, London, United Kingdom, and colleagues was to assess the effect of vitamin D supplementation on rickets risk and linear growth among Afghan children.
The double-blind, placebo-controlled trial included 304 children (aged 1 to 11 months) from Kabul. They were randomly assigned to receive oral vitamin D3 (100 000 IU) or placebo every 3 months for 18 months. Rickets Severity Score was calculated using knee and wrist radiographs for 631 randomly selected infants at 18 months. Rickets was defined as a score >1.5. Length and weight were measured at baseline and 18 months by using standard techniques, and z scores were calculated.
