The Relationship of Serum Vitamin 25(OH)D3-Levels with Women Obesity

Objectives: This paper aims to evaluate the relationship between vitamin D3 levels and
obesity in adult women compared to normal weight women. Method: Ninety-six (96)
women them age around (20-50) years were collected and classified into three groups
based on BMI categories. ELISA kit was used to measure vitamin D3 levels in serum of
blood. Results: The results showed significantly lower vitamin D3 levels (15.28±1.13)
in obese and overweight women (22.46 ±1.31) compared to normal weight group (34.40
±2.43) at p≤ 0.05, and a negative significant correlation between vitamin25(OH) D3
levels and BMI in obese women. Novelty: This finding suggested that vitamin D3
deficiency in obese women may be due to its storage in adipose tissue which reduces its
levels in the bloodstream. In addition to other different mechanism. More studies are
required for detect the complex interchange between vitamin D3 and obesity to know
more about the biological mechanism of action.
