目的：对上海市中国地区膝关节骨性关节炎(OA)的患病率及相关因素进行社区调查。方法：对2305名40岁的户籍居民进行访谈和问卷调查，共2093人。190名膝关节疼痛阳性受试者和510名膝关节疼痛阴性受试者接受了X光检查。结果：72.1%(137/190)有症状组和41.6%(212/510)无症状组出现膝关节骨关节炎(RKOA)。社区中有症状和无症状膝骨性关节炎的患病率估计分别为7.2%和37.4%。女性SKOA患病率高于男性(9.8%vs3.7%，P<；0.01)。与高加索人群相比，上海城市人群胫股关节骨关节炎的患病率较高。结论：SKOA的比例高于AsKOA(72.1%比41.6%)，而且SKOA与残疾的相关性更大(81.0%比26.9%，P<；0.01)。SKOA的患病率随着年龄的增长而增加，从40-49岁年龄组的1.3%上升到70岁以上年龄组的13.2%。年龄、体重指数和女性是膝骨性关节炎的相关危险因素。
Objectives: A community-based survey on the prevalence of knee osteoarthritis (OA) and associated factors was carried out in Shanghai, People's Republic of China. Methods: Of 2,305 registered residents >= 40 years of age, 2,093 were examined by interview and questionnaire. One hundred ninety knee pain-positive and 510 knee pain-negative subjects received radiography. Results: Radiographic knee OA (RKOA) was found in 72.1% (137/190) of symptomatic and 41.6% (212/510) of asymptomatic subjects (SKOA and AsKOA, respectively). The estimated prevalences of symptomatic and asymptomatic knee OA in the community were 7.2% and 37.4%, respectively. Women had higher SKOA prevalence than men (9.8% vs 3.7%, P < 0.01). Compared with Caucasians, the urban Shanghai population had a higher prevalence of tibiofemoral joint OA. Conclusions: There was a higher proportion of SKOA than AsKOA (72.1% vs 41.6%), and SKOA was significantly more associated with disability (81.0% vs 26.9%, P < 0.01). The prevalence of SKOA increased with age, from 1.3% in the 40-49-year-old age group to 13.2% in the 70+ group. Age, body mass index, and female gender were associated risk factors for knee OA.
