Calcium supplementation increases stature and bone mineral mass of 16- to 18-year-old boys.

The effect of calcium carbonate supplementation on bone growth and mineral accretion was studied in 143 boys aged 16-18 yr, randomized to 1000 mg Ca/d or a matching placebo for 13 months. Anthropometry and dual-energy x-ray absorptiometry of the whole body, lumbar spine, hip, and forearm were performed before, during, and after the intervention. The intervention resulted in greater bone mineral content (BMC) of the whole body (+1.

Effect of a calcium and exercise intervention on the bone mineral status of 16-18-y-old adolescent girls.

Background: Osteoporosis may be prevented or delayed by maximizing peak bone mass through diet modification and physical activity during adolescence.

Objective: We studied whether increases in calcium intake and physical activity effectively increase the bone mineral status of adolescent girls aged 16-18 y.

Design: We conducted a 15.
