摘要
目的 了解北京房山区正常成年人的峰值骨量及各年龄段的骨密度 (BMD)水平 ,为今后全国范围内的骨量调查提供参考性数据。方法 采用分层整群抽样调查方法 ,使用美国LUNAR公司的双能X线骨密度仪 (DPX -L)对房山区现有社区医疗服务网内居民及两个人口在 2 5 0 0人以上的行政村村民 ,随机抽样年龄在 2 0～ 89岁的男女人群 ,2 72 6例进行腰椎及股骨颈骨密度的测定 ,将所获得的数据录入SPSS 10 0软件数据库并进行有关统计分析。结果 房山地区成年男女峰值骨量在 3 0～ 3 9岁年龄段 ,女性在 5 0岁以后骨量下降速度明显加快 ,70岁以后呈缓慢下降。男性从 40岁以后骨量呈缓慢下降趋势。结论 BMD达到峰值后 ,随年龄增加而下降 ,女性绝经后骨量丢失明显加快 ,男性下降缓慢 ,女性骨质疏松发病率高于男性。预防和治疗骨质疏松的重点在中老年女性 。
Objective To find out the peak bone mass and bone mineral density(BMD)level in different ages of the people in Fangshan and acquire useful data for investigating bone mass in the country Methods BMD of lumbar spines and neck of femur was measured using DPX-L and questionnaire was surveyed in 2 726 people 20-89 years of age SPSS was used to analyze the data Results The adult peak bone mass was found between 30-39 years of age Female's bone mass decreased quickly after the age of 50 and then slowly after the age of 70 The male's bone mass decreased slowly after the age of 40 The female's maximum muscle strength appears between 20-30 years of age and the males remain high level from the age of 20 to the age of 50 Conclusion After BMD reaches the maximum,Graduate decrease of bone mass with age Female has a more rapid speed of bone loss after menopause while the male has a slower speed of bone loss Female's attack risk of osteoporsis is higher than males' It is more important in old female than in old male to prevent ospeotosis
