The Effect of Vitamin D on Cytokines and Cardiometabolic Risk in Obese Adolescents

Large studies of children show that over half of the children in the United States of America do not have enough vitamin D stored in their bodies. In children who are overweight or obese, the percentage of children who do not have enough vitamin D is even higher. Vitamin D is essential for the body to maintain normal calcium levels and strong bones. Recent research shows that through the actions of inflammatory markers, levels in the blood that measure inflammation in the body, vitamin D plays many other important roles in the body like helping to regulate the immune system, blood sugar levels, blood pressure, and body fat. The purpose of this study is to determine the effect of vitamin D supplementation on inflammatory markers in obese and overweight adolescents. As a secondary goal, we would like to evaluate cardiometabolic risk factors and the correlation between body mass index, vitamin D stores and inflammatory cytokines. In an observed, randomized controlled trial over 6 months we will provide observed vitamin D supplementation or placebo to healthy obese and overweight adolescents and measure changes in inflammatory markers, lipids, blood pressure, and mean blood sugars. We hypothesize that administration of vitamin D to these patients will improve their inflammatory profile and cardiometabolic risk factors (blood glucose, blood pressure, and lipid profile).
