To investigate the prevalence of knee, hip and hand osteoarthritis (OA) in the elderly of Beijing and to compare the prevalence of OA between the Beijing elders and the US Caucasians.
Using the same standardized instruments and protocol as those in the Framingham Osteoarthritis Study, home interview, clinical examination and radiography were conducted among 1012 males and 1507 females, all aged 60 and over, on 4 central districts of Beijing with informed consent. The data of survey were compared with those of the corresponding US study.
The prevalence of radiographic and symptomatic knee osteoarthritis was 42.8% and 15.4% respectively among the women aged 60 and over in Beijing, higher than those in Caucasian women of the same age. The prevalence of radiographic and symptomatic knee osteoarthritis were 27.6% and 7.1% respectively among the men aged 60 and over in Beijing, similar to those in the Caucasian men of the same age. The prevalence of radiographic hand osteoarthritis among the Beijing men and women aged 60 and over were 44.5% and 47.0% respectively, lower than those among the contemporary Caucasian in US. The prevalence of hip osteoarthritis among the men and women aged 60 and over were only 0.4% and 0.6%, significantly lower than those among the contemporary Caucasian in US.
Compared to the Caucasian contemporaries, fewer Beijing elderly suffer from hand and hip osteoarthritis. However, knee osteoarthritis is much more prevalent, affecting millions of elderly Chinese.
调查北京老年人膝关节、髋关节和手部骨关节炎（OA）的患病率，并比较北京老年人与美国白种人OA的患病率。
采用与弗雷明汉骨关节炎研究相同的标准化工具和方案，在北京市4个中心城区对1012名男性和1507名60岁及以上的女性进行了入户访谈、临床检查和X线摄影，所有参与者均签署了知情同意书。将调查数据与美国相应研究的数据进行比较。
北京60岁及以上女性中，X线检查确诊的膝关节骨关节炎患病率为42.8%，有症状的膝关节骨关节炎患病率为15.4%，均高于同年龄段的白种女性。北京60岁及以上男性中，X线检查确诊的膝关节骨关节炎患病率为27.6%，有症状的膝关节骨关节炎患病率为7.1%，与同年龄段的白种男性相似。北京60岁及以上男性和女性中，X线检查确诊的手部骨关节炎患病率分别为44.5%和47.0%，低于美国当代白种人。60岁及以上男性和女性中，髋关节骨关节炎患病率仅为0.4%和0.6%，显著低于美国当代白种人。
与同时代的白种人相比，北京老年人患手部和髋关节骨关节炎的较少。然而，膝关节骨关节炎更为普遍，影响着数百万中国老年人。
