目的 :了解 5 0岁以上人群中骨折史的分布情况。方法 :对成都市某厂 5 0岁以上的 2 2 49人 (男 10 92人 ;女 115 7人 )进行了骨折史的流行病学问卷调查。结果 :总骨折患病率为 2 2 .5 0 % (2 0 .80 %～ 2 4.2 4% ) ,其中男性 19.5 1%、女性2 5 .32 % ,女性骨折高于男性 (P<0 .0 0 5 )。骨折时的平均年龄为 45 .15岁。 40岁后男女骨折的患病率大幅度上升 ,女性尤为明显 ,5 0岁时为男性的两倍。骨折的诱因在男性以外力 (交通事故等 )及摔倒为主 (76 .14% ) ,女性以摔倒为主 (5 5 .93% ) ,男女骨折诱因有明显差别 (P<0 .0 0 5 )。骨折的患病率与家族史有关 (P<0 .0 5 )。结论 :本研究提供了该人群骨折患病率的基本情况
Objectives: To understand the distribution of fracture history in people over 50 years of age. Methods: A total of 2,249 persons (1092 males and 1157 females) over 50 years old in a factory in Chengdu were investigated by epidemiological survey. Results: The prevalence of total fracture was 22.5% (20.8% -2.24%), of which 19.5% were male and 25.32% were female, and the fracture rate of female was higher than that of male (P <0.05). 0 0 5). The average age at fracture was 45.15 years. The prevalence of fractures between men and women has increased dramatically after age 40, especially in women, which is twice as frequent as men at age 50. The predisposing factors of fractures were male (76.14%), falling (55.93%), male and female fractures were significantly different (P <0. 0) 0 5). The prevalence of fractures was related to family history (P <0.05). Conclusion: This study provides the basic information on the prevalence of fracture in this population
