某市社区中老年人群骨质疏松影响因素研究

Influence factors of osteoporosis among middle-aged and older population in communities

目的 分析合肥市某社区中老年人群骨质疏松患病率及其相关影响因素,为社区骨质疏松预防控制提供依据.方法 采用方便抽样的方法,抽取合肥市某社区中的部分40岁以上中老年人群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,平均跟骨超声传播速度（SOS值）男性为（1 496.50±28.51）,女性（1 490.80±27.98）,男性高于女性（t=2.39,P ＜0.05）.骨质疏松患病率为女性高于男性（x^2=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、每天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 性别差异、高龄、少运动、体重指数低、奶类摄入量低和静坐时间过长是该社区中老年入骨质疏松患病危险因素,其中运动、静坐时间和体质指为可控因素.

Abstract：Objective To analyze the prevalence and related factors of osteoporosis among the middle-aged and elderly subjects in Hefei communities, and to provide the basis of control and prevention of osteoporosis. Methods Bone mineral density testing and epidemiological investigation were taken in a part of middle-aged and elderly residents,who were randomly selected from the community of Hefei and their age had been over 40 years. Results Among 820 patients, the average SOS value of calcaneus was higher in male （1 496.50 ± 28.51 ） than in female （1 490.80 ± 27.9, t = 2.39, P 〈 0.05 ）. Prevalence of osteoporosis was higher in female than in the male （2.79% ,x^2 = 27. 8326, P = 0. 000）. Logistic multivariate regression analysis showed that gender, age, body mass index, weekly exercise frequency,milk intakes and sedentary hours per day were the main factors of osteoporosis. Conclusions The differences of gender, age, lack of exercise, lower body mass index , reduced milk intakes and sedentary are the risk factors of osteoporosis among the middle-aged and elderly subjects in community, and exercise, meditation time, body mass index should be reinforced for they are controllable.
