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，女性只有身高与ＢＭＣ有较良好的相关性
Radius bone mass (BMD: bone density, BMC: bone mass) of 692 faculty members aged 24-85 years in Guangzhou colleges and universities was measured using a single-photon bone mineral analyzer. The results showed that the bone mass of all age groups was significantly higher than that of the females. The bone mass of the two groups was the highest in the age group of 30-39 years. The BMD of males was 0.742g / cm2, the BMC was 1.067g / cm, and the females was 0.676g / cm and 0.786g / cm respectively. The bone loss in women about 25 years old decreased from about 50 years old to 70 years old. The bone loss in men was about 10 years later than that in women. From the age of 60 to the age of 70, the BMD Decline of about 18.5%. According to the WHO diagnostic criteria, the prevalence of osteoporosis after 50 years old was 32.6% and 51.4% respectively. In addition, the study found that male BMD, BMC and height and weight had a significant positive linear correlation, only tall women and BMC have a good correlation
