['Overweight adolescents have low bone mineral content for weight and are at increased risk for fractures.', 'The aim was to determine whether overweight and obesity influence the positive relationship between dietary calcium intake and skeletal calcium retention in adolescents.', 'Analysis of pooled data from calcium balance studies in adolescents.', 'Participants each underwent a 3-wk calcium balance study in a controlled environment.', 'Participants included 280 White, Black, and Asian boys (n = 73) and girls (n = 207) ages 10-16 yr.', 'The relationship among body mass index (BMI), calcium intake, and calcium retention was modeled using linear regression.', 'Calcium intake, BMI, sex, race, and age explained 27.9% of the variation in calcium retention. At low calcium intakes, there was no effect of BMI on skeletal calcium retention, but at higher calcium intakes, BMI increased skeletal calcium retention.'] Does obesity augment calcium-induced increases in skeletal calcium retention in adolescents?
