为了研究少女在生长突增阶段的骨密度变化以及与身高增长速度、第二性征发育和营养状况的关系，作者采用双能Ｘ线骨密度测量仪，先后两次测量６９例少女身体多部位的骨密度，了解其一年中的骨密度变化情况。结果表明：生长突增阶段各个部位的骨密度均随着年龄增长而明显增加，但各部位骨密度增加的幅度和时间并不一致。营养状况（超重与体重不足）和少女的性发育状况与骨密度的增加有密切关系，提示：在青春期加强营养对预防骨质疏松是很有必要的。此外，通过与年轻妇女骨密度的粗略比较，初步了解青春期早期是女性骨密度增长的重要时期。
In order to study the changes of the bone density of the girl in the stage of rapid growth and the relationship with the height growth rate, the development of the second sexual characteristics and nutritional status, the author used dual-energy X-ray absorptiometry to measure the number of males’ Of the bone density, understanding of the changes in bone mineral density in the year. The results showed that the BMD of each site increased significantly with the increase of age, but the range of increase of BMD in each site did not agree with the time. Nutrition status (overweight and underweight) and sexual development of girls are closely related to the increase of BMD, suggesting that strengthening nutrition in adolescence is necessary to prevent osteoporosis. In addition, a rough comparison of bone mineral density with young women shows that early adolescence is an important period for female bone mineral density growth.
