摘　　要：应用单光子骨矿分析仪测量了广州高校６９２名年龄２４～８５岁教职工的桡骨骨量（ＢＭＤ：骨质密度；ＢＭＣ：骨质含量）。结果显示男性各年龄组的骨量明显高于女性；两性在３０～３９岁组骨量最高；男性ＢＭＤ为０．７４２ｇ／ｃｍ２，ＢＭＣ为１．０６７ｇ／ｃｍ；女性则分别为０．６７６ｇ／ｃｍ２和０．７８６ｇ／ｃｍ；女性骨质丢失约从５０岁开始至７０岁后ＢＭＤ约下降２５．７％，男性的骨质丢失比女性晚约１０年，从６０岁开始至７０岁后ＢＭＤ下降约１８．５％。按ＷＨＯ建议诊断标准，５０岁后骨质疏松患病率男、女分别为３２．６％、５１．４％。另外，研究发现男性ＢＭＤ、ＢＭＣ与身高、体重有显著的线性正相关。The bone mineral status of distal radius of 692 persons were measured by singlephoton densitometry they are the staff members of various colleges and universities in Guangzhou and their age range was 24～85. It was found that the bone mass of the male was obviously higher than that of the female in any age period. And the peak of bone mass was achieved between 30～39 yr in both sexes(male: BMD 0.742g/cm 2, BMC 1.067g/cm; female: BMD 0.676g/cm 2, BMC 0.786g/cm). The female began to lose their bone mass at the age of 50, and the BMD would be lost 25.7% when they were over 70 yr, on the contrary, the male began to lose 10 year later and lost only 19.6% of the BMD after their 70 yr. According to the diagnostic standard proposed by WHO, the prevalence of those suffering osteoporosis will be 32.6% for the male, 51.4%. Besides, it was also found that the bone mass of the male was in an obvious positive line correlation with their height and weight in our study; but in female, only height was correlated with BMC.
