Low serum 25-hydroxyvitamin D level is associated with obesity and atherogenesis in adolescent boys

Purpose: We investigated the relationship of 25-hydroxyvitamin D (25[OH]D) level with obesity and atherosclerosis in Japanese adolescents.Methods: We examined 492 children (247 boys and 245 girls) aged 12–13 years. The serum 25(OH)D level was compared among underweight, healthy weight, and overweight children. Spearman correlation coefficient analysis was performed to examine the relationships between the 25(OH)D level and body mass index (BMI), plasma lipids, and blood pressure and to compare the latter between the normal (≥20 ng/mL) and low (
