Abstract

Obesity is considered as a global epidemic. It is associated with risk of multiple health problems. Vitamin D deficiency is prevalent in India. Vitamin D deficiency is increasingly associated with insulin resistance, type 2 DM and CVD, conditions also commonly linked with overweight and obesity.
Aims:
Comparison of vitamin D3 levels in normal, overweight and obese individuals without comorbidities.
Settings and Design:
Cross sectional observation study
Methods and Material:
189 eligible individuals were enrolled, divided into 3 groups based on BMI- normal, overweight, obese according to guideline for Asian population. Excluding secondary obesity. Blood samples for vitamin D measurement and anthropometric measurements were taken.
Statistical analysis used:
Comparison among different BMI categories will be done using ANOVA (Analysis of variants) followed by post hoc comparison.
Results:
Our study revealed that Hypovitaminosis D was most common in the obese and subjects with central obesity. Overall 64.6% had Vitamin D deficiency, 22.2% had insufficiency, only 13.2% had normal vitamin D. Hypovitaminosis D was observed in 68% of subjects with central obesity as compared to 32% without central obesity.
Conclusions:
In our study there was hypovitaminosis D in all 3 groups, but the mean level of 25(OH) D was very low in obese and overweight individuals without comorbidities and hypovitaminosis D directly proportional to the central obesity. Overall vitamin D deficiency is present in even normal individuals.
