Calcium Supplementation and Increases in Bone Mineral Density in Children

Scientists have found that peak bone mass in childhood is a major cause of bone mineral density in adulthood and may decrease the risk of osteoporotic fractures. Osteoporotic fractures are those caused by a disease (Osteoporosis) which causes bones to be extremely porous. There are however other factors, such as Genetic and Environmental, that play a major role in determining peak bone mass. Studies done have implied that milk drinking may help in determining peak bone mass. Since milk is a complex food, other factors, not just the calcium, may be responsible for the increase in bone mass. Teenaged girls were studied, and scientists found that an increase in either milk drinking or calcium supplements was positively proportional to the rate of gain in bone mineral density.

Is calcium alone an effective tool in increasing the rate of change in bone mineral densit

In conclusion, only the rate of increase in bone mineral density was positively affected by the calcium supplementation. The group who received an average of 719mg per day of calcium supplements had about 3 percent more minerals in the radius than their twins. One factor that was very significant was sexual maturity. Prepubertal twins had about 4 percent greater increase in bone density while postpubertal and those going through puberty had little change. To account for these differences, scientists considered dose sizes and pubertal changes. They believed that pubertal changes such as the secretion of growth hormones and sex steroids were the main cause for the differences. Bone is either changing so rapidly or maximally stimulated that small effects of greater calcium intake can not be detected.

A three year, double blinded, placebo controlled study was done on 70 pairs of identical twins whose ages ranged from 6 to 14 years old. Of the 70 pairs, only
