Association Between Body Fat Masses with Vitamin D Serum in Adolescent with Obesity

Background: vitamin D is a fat soluble vitamin. The study found obese people had lower vitamin D levels and tended to have vitamin D deficiency. The purpose of this study was to determine the relationship between body fat mass and vitamin D levels in adolescents with obesity. Methods: This was an analytic cross sectional study with the subject of obese adolescents aged 12-15 years and was recruited consecutively at several schools in the city of Denpasar. Body fat mass is calculated using Parizkova method. The correlation between body fat mass and vitamin D was tested using linear regression. Results: Thirty-three subjects with the majority male sex were analyzed to have a mean body fat mass of 3.41 %, with a mean vitamin D value of 18.41 ng/mL. A moderate negative relationship was found between body fat mass and vitamin D (r = -0.421 with P = 0.015). Conclusion: This study found that in adolescents with obesity there is a moderate negative relationship between the mass of body fat and vitamin D
