目的分析徐家汇街道社区老年人骨质疏松症的相关因素,为制定社区老年人骨质疏松症防治对策提供依据。方法社区卫生服务中心与上海市第六人民医院骨质疏松症科合作,应用双能X线骨密度仪对参加本中心65岁以上老年人健康体检的342名老年人进行骨密度测定,按骨密度测定值分为正常对照组和骨量减少及骨质疏松症组,采用Logistic回归分析影响骨密度的相关因素。结果在调查的342名老年人中,骨密度正常者占26.3%,骨量减少及骨质疏松症者占73.7%,女性骨质疏松症患病率显著高于男性,差异有统计学意义(P<0.01)。多因素Logistic回归分析显示,年龄、性别、曾因轻微碰撞或跌倒伤到骨骼、身高较年轻时降低>3 cm、经常腹泻和45岁前绝经者为骨质疏松症的主要影响因素。结论女性、高龄、曾因轻微碰撞或跌倒伤到骨骼、身高较年轻时降低>3 cm、经常腹泻和45岁前绝经者是该社区老年人骨质疏松症患病的高危因素,提示应加强有该方面因素老年人骨质疏松症的防治工作。

OBJECTIVE To analysis of realated factors of osteoporosis in people over 65 years old in Xujiahui street, provide the basis for prevention and countermeasures. METHODS To cooperate with the osteoporosis department of shanghai N0.6 people＇s hospital. BMD was measured by dual-energy X-ray absorptionetry in 342 elderly peoples, All the peoples were divided into 2 groups： the normal bone mass group and the osteopenia or osteoporosis group according to the determination of BMD. RESULTS In 342 cases, the occurrence rate of the normal bone mass group was 26.3%, and 73.7% for the osteopenia or osteoporosis group. The female prevalence rate of osteoporosis was significantly higher than that of male. The difference was statistical significance.Logistic regression analysis showed that gender, age, history of fracture, more than 3cm shorter than younger, diarrhoea and postmenopausal women before the age of 45 were the risk factors for osteoporosis. CONCLUSION Osteoporosis was related to gender, age, history of fracture, more than 3cm shorter than younger, diarrhoea and postmenopausal women before the age of 45, so it needs to strengthen the prevention and treatment of elderly osteoporosis for these reason.
