大学生饮食运动与骨密度的关系

目的探讨饮食、运动等因素对大学生骨密度的影响。方法用问卷调查方法获得学生饮食及运动情况，用单光子骨密度仪测定骨密度（ＢＭＤ）及骨矿物含量（ＢＭＣ）。结果大学生男性桡骨ＢＭＣ显著高于女性（Ｐ＜０．０５），锻炼强度及锻炼频数与ＢＭＤ和ＢＭＣ呈显著性正相关（Ｐ＜０．０１），经常摄入豆类制品者尺骨骨密度和尺骨、桡骨骨矿物含量增高（Ｐ＜０．０５），表明经常摄入豆制品有利于骨的形成，但膳食中也可能存在许多影响钙吸收的因素。结论饮食和运动可影响ＢＭＤ和ＢＭＣ。

Relation between food or exercise and bone mineral density

Objective To investigate the bone mineral density(BMC) of college students and search for the affective factor on bone mineral density.Method The questionaire was used to collect informatiion about foodseaten and exercises done by college students.The bone mineral density and the bone mineral contents(BMC) of 236 medical college students was measured with single-photon absorptiometry .Results The radial bone mineral content of male students was significantly higher than that of female ( P <0.05). The frequency and the intensity of exercise had significant positive correlation with bone mineral density and bone mineral content. The bone mineral density and the bone mineral content were higher in the students of eating bean products food frequently.Conclusion The food and the exercise could affect the bone mineral density of college students.
