摘　　要：目的　调查辽宁地区正常人群骨密度值及骨质疏松患病率 ,为骨质疏松的预防提供科学依据。方法　对辽宁地区一般人群随机抽样 2 30 0例 ,应用美国Lunar公司生产的双能X线骨密度仪分别测试受试者的L2 - 4及股骨上段 (包括股骨颈 ,Ward’s区及粗隆部位 )的BMD值。结果　各检测组的BMD峰值均出现于 2 0～ 2 9岁组 ,且BMD随年龄增加而逐渐降低 ,进入 5 0～ 5 9岁组 ,女性的骨量丢失速度明显加快 ,尤以Ward’s区明显。 6 0～ 6 9岁年龄组的骨质疏松症患病率 ,男性为2 7% ,女性为 4 6 8%。结论　BMD随年龄增长而下降 ,骨质疏松发病率也随之增加 。Objective\ To investigate the BMD and the incidence of osteoporosis(OP)in normal people in Liaoning Province of China,and provide scientific basis for diagnosis and treatment of osteoporosis. Methods 2300 random samples were obtained from healthy adults in Liaoning Province.Their BMD of L 2-4 and upper femur were measured by dual energy X ray absorptiometry(DEXA),then statistically analyzed. Results\ The peak value of BMD appeared during 20 to 29 years of age in every groups and BMD decreased with age During 50 to 59 years of age,the BMD of females dropped obviously,especially in Ward's area.In the age group of 60-69 years,the incidence of osteoporosis in Ward's area was 27% in men,and 46 8 in women. Conclusion\ BMD decreases with age,and the incidence of osteoporosis increases with age. The incidence of OP in females is higher than that in males.
