We assessed the effect of vitamin D supplementation on related biochemistry, infection and dentition of the infant. In a double-blind, placebo-controlled trial conducted in Lucknow, India (latitude 26°N), 230 mother -newborn pairs were randomised to receive, for 9 months, 3000µg/month oral vitamin D3 by the mother (group A) or 10 µg/d by the infant (group B ) or double placebo (group C).
All babies received 15 min of sun exposure (unclothed) during massage.
Infants' median 25-hydroxyvitamin D ( 25(OH)D) was lower in group C (median 45·3; interquartile range (IQR) 22-59·5 nmol/l) than in groups A (median 60·8; IQR 41·3-80·5 nmol/l (P7.5µkat/l) was significantly more frequent in group C babies (16 %) than in group A (4 %) or group B (0 %) babies. The number of days with respiratory or diarrhoeal infection by 9 months of age was higher in group C (median 46·5; IQR 14·8-73·3 d) than in group A (median 18·5; IQR 8·8-31·0 d (P<0·01)) or group B (median 13·0; IQR 7·0-28·5 (P<0·05)). We conclude that monthly maternal or daily infant supplementation with vitamin D along with sun exposure is superior to sun exposure alone in maintaining normal infant 25(OH)D at 3·5 months, and provide protection from elevated alkaline phosphatase and infectious morbidity.
