Vitamin D deficiency/Vitamin Insufficiency (VDI) is now recognized as a pandemic. Cutaneous exposure to ultraviolet-B causes photolysis of epidermal 7-dehydrocholesterol, converting it pre-Vitamin D3 (precholecalciferol), which then undergoes isomerization form the stable hormone D3.The objectives study determine status level among adults residing in rural area West Bengal and find out optimal cutoff sun for sufficiency.This was community based cross-sectional study. It done from May 2016 April 2017 197 block Bengal. Data were collected by interviewing respondents with help structured pre-tested pre-designed schedule. After interviewing, every individual examined height weight blood serum 25-(OH) D. Receiver Operating Characteristic (ROC) curves utilized optimum cut-off using Youden's index. Binary logistic regression performed associates high exposure. All analysis R.Overall VDI found 133 (67.5%). Among them, 102 (51.8%) female. On ROC curve veritable sufficiency, under 0.7841 signifies good screening tool.Proper information, education, communication material regarding various aspects should be prepared due consultation field experts disseminated increase awareness community.
