The achievement of a peak bone mass is an important factor in the prevention of osteoporotic fractures. In normal children, the amount of calcium intake could affect bone mineral increment.
To assess the effect of a daily 500 mg calcium supplement on bone mineral density, in a group of healthy Chilean girls.
Fifty healthy girls were studied and 25 were randomly assigned to receive a 500 mg calcium supplement during 10 months. Bone mineral density of the distal and ultradistal region of the forearm was measured in all girls by single X ray absorptiometry (Osteometer DTX-100) at the beginning and end of the study. Bone mineral density was expressed as Z values.
Significant increments in bone mineral density at the distal radioulnar region were obtained in the supplemented girls. No significant changes in bone density were observed in control girls.
A daily 500 mg calcium supplement for 10 months increased bone mineral density in healthy girls.
达到峰值骨量是预防骨质疏松性骨折的一个重要因素。在正常儿童中，钙摄入量会影响骨矿物质增加。
评估每日补充500毫克钙对一组健康智利女孩骨密度的影响。
对50名健康女孩进行研究，随机将25名女孩分配到补钙组，在10个月内每日补充500毫克钙。在研究开始和结束时，通过单能X线吸收法（Osteometer DTX - 100）测量所有女孩前臂远端和超远端区域的骨密度。骨密度以Z值表示。
补钙组女孩的桡尺骨远端区域骨密度有显著增加。对照组女孩的骨密度未观察到显著变化。
健康女孩每日补充500毫克钙，持续10个月，可增加骨密度。
