Distributed on 66 large occupational groups the prevalence of classical, definite, probable and possible RA (according to ARA criteria) was determined in the general population. A total of 39, 418 persons were investigated in a sample survey of five geographical areas in Sweden-this being the total populations over the age of seven. The distance between the different areas is 150-650 km. Occupational groups with high prevalence of RA were: Males: Food and dairy workers, butchers, fishermen, agricultural workers, building foremen, machine and engine repairers, bakers, foremen, washers and ironers, textile workers, industry and factory workers. Females: Cleaning workers, doctors and nurses, nurse assistants, textile workers, shop assistants, bank, post and telegraph personnel and wives. From the present series it seems as if outdoor occupations with relatively heavy work have the highest prevalence of RA. Environmental factors apparently account for differences in prevalences of RA.
在瑞典五个地理区域的抽样调查中，对 66 个大型职业群体进行了研究，以确定普通人群中经典的、明确的、可能的和可能的 RA（根据 ARA 标准）的流行率。共有 39418 人接受了调查，这是所有 7 岁以上的人群。职业群体中 RA 患病率较高的有：男性：食品和奶制品工人、屠夫、渔民、农业工人、建筑领班、机器和发动机修理工、面包师、领班、洗涤工和熨烫工、纺织工人、工业和工厂工人。女性：清洁工人、医生和护士、护士助理、纺织工人、店员、银行、邮电人员和妻子。从本系列中可以看出，户外职业且工作量较大的职业 RA 患病率最高。环境因素显然是 RA 流行率差异的原因。
