Prevalence of Vitamin D Deficiency Among Urban Working Adults: A Cross-Sectional Study

Vitamin D deficiency is increasingly reported among adults who spend most of the day indoors. This cross-sectional study assessed serum vitamin D levels among office workers in an urban setting and examined their association with sun exposure, diet and physical activity. Deficiency was common across age groups and was associated with limited daytime sun exposure and low dietary intake. The findings support workplace screening, awareness programmes and simple lifestyle measures.
