The Relationship of Central Obesity to Vitamin D Levels in Medical Faculty Students of Udayana University in Year 2023

Background: Central obesity is defined as the accumulation of excess fat in the abdomen as a result of an energy imbalance caused by genetic and environmental factors. Obesity may contribute to vitamin D deficiency (<20 ng/mL) and insufficiency (20–29.9 ng/mL). Vitamin D is an important vitamin for the body and is fat-soluble. It can be synthesized by exposure to ultraviolet B light by converting 7-dehydrocholesterol into 1,25-dihydroxyvitamin D3 through hydroxylation in the liver and kidneys and then binding to the vitamin D receptor to carry out its function. Based on previous research, the mechanism for decreasing vitamin D levels in obese people can be explained through three theories: volumetric dilution, sequestration theory, and degradation theory. Method: The purpose of this study is to determine the relationship between central obesity and vitamin D levels in college students at the Faculty of Medicine, Udayana University, in 2023. This study used a quantitative analytical methodology with a cross-sectional design. The study's dependent variable was waist circumference, while the independent variable was vitamin D levels.
