| 本文随机对北京市区20~94岁人群中1333人进行了不同部位的双能X线骨密度(BMD)的调查，其中女性 740人，男性 593人，按10岁为一年龄组，将其分为8组，结果显示：腰椎骨峰值女性见于30~39岁，男性见于20~29岁，股骨上端(Neck、Wards、Troch)骨峰值男、女均见于 20~29岁。BMD累积丢失率女性较男性高，无论男、女股骨上端高于腰椎，股骨上端三个部位中又以Wards为著。女性50岁后可见骨量丢失加速，男性呈缓慢丢失。 同性别、同部位峰值BMD减低两个标准差为诊断骨质疏松症的标准，骨质疏松症患病率49岁前无论男性或女性均在10% 以内，50岁以后随年龄增长而增加， 累积丢失率最高的部位统计，50岁以上女性约为30%~40%，男性25%~30%，60岁以上女性约为60%~70 %，男性25%~35%；70岁以上女性达 80%~90% ，男性48%~56%；80岁以上女性达85%~100 %，男性达50%~65%。 股骨上端各部位骨质疏松症检出率明显高于腰椎。提示：骨质疏松的研究重点在女性，但对男性也不容忽视 股骨上端各部位BMD检测敏感性高于腰椎，对腰椎BMD正常，但有明显骨质增生者应参考股骨上端 BMD方能作出正确评价。 |

| In the article, the dual energy X ray bone mineral density(BMD) was investigated randomly in Beijing for1333 people．There were740 females and 593males over 20 years old, which were divided into 8 groups by every ten years．The results showed that the BMD peak values of lumbar vertebral could be seen in 30~39 years old group for females and in 20~29 group for males．However the values of femoral neck, wards triangle and trochanters were found in 20~29 years old group of both males and females．The rate of accumulative loss of BMD seemed higher for females than for males. In both sexes, the rates of accumulative loss of BMD of femoral neck, ward’s triangle and trochanters were higher than that of lumbar vertebral, and the highest rate in wards triangle．The rate of loss was increased for females after 50 years old，but that for males was slower than for females over 50 years old．The morbidity of osteoporosis was less than 10% in both sexes before 49 years old, after 50 years that was increased with age．Statistics according to the most significant parts of the rate of loss，the morbidity showed 30%~40% and 20%~30% for females and males over 50 years old respectively，60%~70% and 25%~35% over60, 80%~90% and 48%~56% over70，85%~ l00% and 50%~ 65% over80 years old．The detectable rate of osteoporosis in the upper parts of femoral bone was higher than that of lumbar vertebral．We suggested that the investigation of osteoporosis is more important for females but should not be ignored in males．The sensitivity of the determination of BMD in the upper parts of femoral bone is higher than that in lumbar vertebral. To normal BMD in lumbar vertebraI but with significant hyperosteogeny，we could do correct assessment only after referring to the BMD of the upper parts of femoral bone. |
