Our study, from North India, confirms the high prevalence of vDD in both men and women in older age groups. The mean 25(oH)D level observed by us in this population of older subjects was 9.79±7.61 ng/ml. We and other investigators have earlier reported similarly low levels in different age of healthy individuals in north India, mean 25(oH)D level ranging from 4.5 ng/ml15 – 20.85 ng/ml.3 In contrast, higher serum 25(oH)D levels, 25.3±7.4 ng/ml in females in summer and 18.4±5.3 ng/ml in males in winter have been observed in paramilitary personnel who as a consequence of their professional duties have greater sunlight exposure.16
