Study on The Association Between Vitamin D and Body Composition in Obese Children and Adolescent
[Objective]To investigate the association between serum 25-hydroxyvitamin D[25-(OH)D]levels and body composition in obese children and adolescents.[Method]A total of 289 obese children aged 6-18 years were selected as the study subjects.Serum 25-(OH)D levels were measured and body composition was assessed using bioelectrical impedance analysis(BIA).The association between serum 25-(OH)D levels and BMI as well as body composition indices were analyzed.[Result]Deficiency and insufficiency rates of vitamin D is 25.6％and 43.3％,respectively.There were statistically significant differences in BMI and body composition indices among different groups of vitamin D nutritional status.Multiple linear regression analysis showed that after adjusting body fat percentage were linearly negatively correlated with serum 25-(OH)D levels.BMI as well as body fat percentage,VFA,FMI,AFMI,and TFMI were associated with an increased risk of vitamin D deficiency(P＜0.05).[Conclusion]Body composition of obese children influences serum 25-(OH)D levels,particularly the amount and distribution of body fat.
