Influence of Dairy on Bone Accrual and Bone Size and Fat and Lean Mass in Early Pubertal Overweight vs. Healthy-weight Boys and Girls
Building stronger bones during pubertal growth could reduce lifelong fracture risk. This
project is an 18 month dairy intervention study for overweight and healthy weight 4th-8th
grade boys and girls. Half of the girls will receive dairy products to add to their habitual
diet (milk, yogurt, and cheese) to equal three products per day, while the other half will
remain on their normal diet. All participants will attend four study visits, each 6 months
apart. At these visits height, weight, bone density and geometry, and fat and lean mass will
be measured. This study aims to show that meeting calcium requirements by eating dairy
products builds bigger, stronger bones, and that this effect may be enhanced in overweight
boys and girls. The effect of the dairy intervention on body fat, lean mass, and weight, as
well as the mechanisms and predictors of changes in bone mass and size and body composition
will also be evaluated.
