Objective: To determine the hypovitaminosis D prevalence and risk in healthy Pakistani adults. Study Design: A cross-sectional multicentre study. Place and Duration: In two major Hospitals of Southern Punjab, Nishtar Hospital, Multan and Bahawal Victoria Hospital, Bahawalpur from July 2017 to January 2018. Patients of different age group visited various departments. Methodology: In this study, 244 healthy adults between the ages of 16-62 visited the two major hospitals of Nishtar and BVH as a patient assistant and met the criteria for participation and exclusion. After the written permission was received, a survey was conducted on age, gender, occupation, exposure to sun, exposed area, type of housing used, eating habits and clothing. By electrochemiluminescence assay, Serum 25-OH vitamin D3 levels were checked and deficiency of vitamin D was considered when <20 μg / ml. In all these patients alkaline phosphatase and serum calcium phosphorus were checked. Findings: Of the 244 persons aged 16-62 years, women were 193 (79%). The volunteers were mostly married (73%), most of them lives in apartments (48.5%). Mostly sun exposure was 1-2 hours / day (42%). The majority wears outfits in different colors (73%) and in 41% fabric. 186 (75.99%) subjects were exposed to Vitamin D deficiency and significant exposure to sunlight, exposed deep, Vitamin D consumed diet and large area of clothing color. While serum was positive for calcium, vitamin D showed a significant negative correlation with serum phosphorus and alkaline phosphatase. Conclusion: The hypovitaminosis D prevalence in healthy Pakistanis is at peak and Sun exposure the duration is the most important determinant of hypovitaminosis D. Key words: healthy individuals, hypovitaminosis D, risk factors.
