EPIDEMIOLOGICAL INVESTIGATION ON THE HISTORY OF FRACTURE AND ITS INFLUENTIAL FACTORYS IN CHENGDU

目的 :了解成都地区人群中一生中骨折发生的情况及影响因素 ,为防治骨质疏松提供依据。方法 :对四川省成都市≥ 5 0岁的常住人口按整群随机抽样方法抽取 10 930人 (男 5 2 45人 ,女 5 6 85人 )进行既往骨折情况的流行病学调查 ,对影响骨折发生的因素采用非条件单因素和多因素 logistic回归分析方法进行分析。结果 :该人群一生的骨折率为 18.75 % ,女性为 2 1.11% ,男性为 16 .19% ;城市骨折的发生率高于农村 ,分别为 2 7.13%及 12 .2 6 % ,性别及城乡间均有显著性差异(P<0 .0 1)。股骨颈、脊柱和前臂的骨折率分别为 1.42 %、 2 .14%及 4.71%。经 L ogistic回归分析发现 ,骨折与性别、遗传呈正相关 ,与劳动强度、睡眠时间呈负相关 (OR<1)。结论 :人群中发生骨折的危险性女性较男性高 ,城市较农村高 ,劳动强度、睡眠时间、遗传等因素可影响骨折的发生。

Objective:Understanding the epidemic situation of fracture occurred in ones life and its influential factors.Supplying some advice for osteoporosis prevention.Methods:We selected 10930 residents aged over 50 years with cluster sampling(there were 5245 men and 5685 women).Subjects answered the questionnaire about the fracture.Analyzing the influential factors of the fracture with simple and multiple nonconditional logistic regression analysis.Results:The incidence rate of fracture was 18 75%,21 11% in women and 16 19% in men( P <0 01).27 13% in urban and 12 26% in rural( P <0 01).The incidence rates of fracture in femur neck,spine and forearm were 1 42%,2 14%,and 4 71%,respectively.Sex,and heredity were significantly associated with increased risk of fracture.Lower intensity of labor and enough sleeping time were protective factor.Conclusions:Incidence rate of fracture in women in higher than one in wen,and in urban in rural.The influential factors of fracture were sex,heredity,intensity of labor and sleeping time.
