Retrospective Analysis of Vitamin D Levels in Office Going People in South India
Journal Title: Indian Journal of Nutrition - Year 2018, Vol 5, Issue 1
Abstract
Background & objectives: Vitamin D is a sunshine vitamin and is one of the fat-soluble vitamins. Vitamin D regulates the absorption of calcium from the small intestine. Though sunshine is abundant in India, there is widespread prevalence of varying degrees (50-90%) of Vitamin D deficiency among Indians. This study was conducted to evaluate the status of the Vitamin D in office going people who get very little opportunity to expose to mid-day sun light. Methods: This is a retrospective analysis of Vitamin D data, collected from employees of the corporate offices and manufacturing plant in Bangalore. Venous blood samples were collected in the month of August and Vitamin D 2 was measured using Chemiluminescence method. Results: A total of 2477 subjects’ vitamin D data were evaluated. Among them 2154 were men and 323 were women. More than 83% of women and 75% of men were deficient in Vitamin D levels. Only 1.7% of men and 3.7% of women had normal Vitamin D levels and remaining had insufficient levels. Interpretation & conclusions: Office going people have minimal time to expose themselves to sunlight and hence are more prone for sunshine vitamin deficiency. The study clearly brings forth the importance of exposure to sunlight, periodic Vitamin D screening, strategies for the prevention of Vitamin D deficiency like food fortification with vitamin D and Vitamin D supplements.
