Adequate Dairy Intake on Weight Change in Girls (DQ)
SPECIFIC AIM The aim of this study is to determine if increasing calcium intake to recommended levels with dairy foods in adolescent females with habitually low calcium intake and above-the-median body mass index (BMI) for sex and age will decrease body fat gain compared to similar females who continue their low calcium intake. .
HYPOTHESIS Post-menarcheal adolescent girls with habitually low calcium intake who consume dairy foods providing at least 1200 mg of calcium per day will have a smaller increase in percent body fat, as measured by dual energy absorptiometry, during one year than post-menarcheal adolescent girls on a usual diet of 600 mg of calcium per day or less.
