An epidemiological survey of rheumatoid arthritis (RA) was undertaken in a tribal Xhosa community in the Transkei of Southern Africa. 577 respondents aged 18 and over were examined clinically and of these, 549 were investigated radiologically and 482 serologically. The presence of RA was then assessed by means of a modification of the Rome criteria, as used in previous comparable surveys. The prevalence of 'definite' RA in the adults aged 18 and over in this population was 0-68% and of 'probable' RA, 1-6%. The combined 'definite' and 'probable' prevalence was 2-2%. The relatively low prevalence of RA in this population is consistent with the results of other surveys in unsophisticated African Negro populations in West Africa and South Africa, and contrasts with the higher prevalence encountered in an urbanized South African Negro community and in populations in Europe and the USA.
在非洲南部特兰斯凯的一个科萨部落社区开展了一项类风湿性关节炎（RA）的流行病学调查。对577名18岁及以上的受访者进行了临床检查，其中549人接受了放射学检查，482人接受了血清学检查。然后采用先前类似调查中使用的罗马标准的修订版来评估RA的存在情况。该人群中18岁及以上成年人“确诊”RA的患病率为0.68%，“可能”RA的患病率为1.6%。“确诊”和“可能”的合并患病率为2.2%。该人群中RA相对较低的患病率与西非和南非未开化的非洲黑人人群的其他调查结果一致，与城市化的南非黑人社区以及欧洲和美国人群中较高的患病率形成对比。
