目的 分析合肥市社区中老年人群骨质疏松患病率及其相关影响因素,为社区跟骨骨质疏松的预防控制提供依据.方法 采用随机抽样的方法,抽取合肥市天鹅花园社区中部分40岁以上中老年人进行跟骨骨密度检查和流行病学调查.结果 在调查的820例中老年人中,平均跟骨超声传播速度(SOS)男性为(1 496.5±28.5)m/s,女性为(1 490.8±28.0)m/s,男性跟骨SOS显著高于女性,差异有统计学意义(t=2.39,P＜0.05).女性跟骨骨质疏松患病率(18.88%)显著高于男性(2.79%),差异有统计学意义(x2=27.8326,P=0.000).多因素Logistic回归分析显示:性别、年龄、体质指数、每周运动次数、奶类摄入及每天静坐时间为骨质疏松的主要影响因素.结论 女性、高龄、少运动、体质指数低、奶类摄入量低和静坐时间过长是该社区中老年人骨质疏松患病危险因素,其中运动、静坐时间和体质指数为可控因素.%Objective To analyze the prevalence and influencing factors of osteoporosis among mid - aged and elderly community residents in Hefei, An'hui Province. Methods Bone mineral density test and epidemiological survey were performed among mid - aged and elderly community residents randomly selected from an urban community in Hefei, Anhui Province. Results Among 820 subjects, the average speed of sound ( SOS ) of calcaneus was significantly higher in the males ( 1 496. 5 ±28. 5 m/s ) than in the females ( 1 490. 8 ±28. 0 m/s, t = 2. 39, P ＜ 0. 05 ). The prevalence of osteoporosis was significantly higher in females than in the males ( 18. 88％ vs. 2. 79％ , x2 =27. 8326 , P = 0. 000 ). Logistic multivariate regression analysis showed that gender, age, body mass index, weekly exercise frequency, milk intake, and sedentary hours per day were the main influcning factors of osteoporosis. Conclusion Gender ( female ), age ( elderly ), lack of physical exercise, lower body mass index, reduced milk intake, and sedentary are the risk factors of osteoporosis among mid - aged and elderly community residents , among which physical exercise , rest time , and body mass index are controllable factors.
