摘　　要：为了研究体成分与骨密度（ＢＭＤ）之间的关系，因体重与ＢＭＤ显著相关，体成分各个组成相加等于体重，而体成分与ＢＭＤ的关系仍不清楚。方法随机选取２０６名１６～５２岁健康的男女性汉族人，用双能Ｘ射线吸收法（ＤＸＡ）测量ＢＭＤ与体成分，进行ＢＭＤ与体重，体成分的多元线性回归分析。结果体重，瘦组织（ＬＴＭ）与男女性的ＢＭＤ显著正相关，脂肪组织（ＦＴＭ）仅对女性全身，腰椎ＢＭＤ起显著性作用。结论影响男女性ＢＭＤ的体成分中，ＬＴＭ是主要因素，ＦＴＭ仅对女性ＢＭＤ有影响。本文较全面地研究了体成分与ＢＭＤ的关系。To study the relationship between body weight, body composition and bone mineral density(BMD). Methods In 206 randomly selected healthy men and women,aged 16 to 52,BMD and body compsition were measured by dual-energy X-ray absorptiometry (DXA),and BMD, body weight and body composition were analyzed by multiple linear regression. Results There is a significant positive correlation between body weight,lean tissue mass (LTM) and BMD in men and women. Fat tissue mass(FTM) has significant effect on BMD of total body and lumbar spine in women only. Conclusion The effects of body composition on BMD are mainly attributed to LTM in men and women,FTM is the contributing factor of BMD of total body and lumbar spine in women.
