中文摘要：

目的 了解山西省农村地区症状性OA流行状况.方法 在山西省阳城县、偏关县采用多阶段分层整群抽样法选取乡镇和村,对选中村的16岁以上居民按WHO社区控制风湿病规划（COPCORD）程序进行调查,所有被调查者均签署知情同意书.有症状者由风湿科医生即时进行体检.可疑OA者10d内拍摄相应部位X线片.X线片由2名放射科医生独立进行读片,最后由3名风湿科医生根据检查结果做出诊断.采用SPSS 13.0和SAS 9.2软件进行统计学分析.率的比较采用r检验,以P＜0.05为差异有统计学意义.结果 两地共调查常住居民7 126名,检查出症状性OA患者1 734例,患病率24.3％.在各关节患病率中,膝OA患病率最高,为13.8％（983/7 126）;其次分别为腰椎、颈椎、手、肩、肘、踝、髋、腕、胸椎和足.其中膝、踝、颈、肩、手患病率不同性别间差异有统计学意义（P＜0.05）.结论 山西省农村人群症状性OA患病率总体较高,相关危险应引起足够重视.
