Abstract:
To study plasma 25-hydroxyvitamin D (25(OH)D) status of children in Kerala, southern India, and its relationship with sociodemographic variables. Design Cross-sectional observational study. Setting Tertiary government hospital. Participants Children ( n 296) with trivial acute illness were enrolled. Sun exposure and Ca and vitamin D intakes (7 d dietary recall) were documented. Serum Ca, P, alkaline phosphatase, plasma 25(OH)D and parathyroid hormone (PTH) were measured. Results Prevalence of vitamin D deficiency (plasma 25(OH)D 〈 30 nmol/l) was 11·1% (median, interquartile range (IQR): 52·6, 38·4–65·6 nmol/l). Children who ate fish daily had significantly higher plasma 25(OH)D than those who did not (median, IQR: 52·5, 40·8–68·9 v . 49·1, 36·2–60·7 nmol/l; P = 0·02). Those investigated in the months of March–May showed highest 25(OH)D v . those enrolled during other times (median, IQR: 58·7, 45·6–81·4 v . 45·5, 35·6–57·4 nmol/l; P 〈 0·001). Plasma 25(OH)D correlated positively with serum P ( r = 0·24, P 〈 0·001) and Ca intake ( r = 0·16, P 0·03), negatively with age ( r = −0·13, P 0·03) and PTH ( r = −0·22, P 〈 0·001.). On linear regression, summer season (March–May), lower age, daily fish intake and higher Ca intake were independently associated with plasma 25(OH)D. Conclusions Prevalence of vitamin D deficiency is low in Kerala. The natural fish diet of coastal Kerala and the latitude may be protective. Public health policy in India should take account of this geographical diversity.
