To evaluate the role of socioeconomic factors in susceptibility to rheumatoid arthritis (RA).
A prospective population based register of inflammatory joint disease (NOAR) recruited 687 adults between 1990 and 1992, of whom 50% satisfied ARA criteria for RA at presentation. Using census data, social class specific incidence rates were calculated for both sexes. A correlation analysis was undertaken examining the association between incidence rates and 5 indicators of socioeconomic status.
There was no trend of increasing incidence with declining social class. None of the 5 indicators examined showed any evidence of association with incidence (rs range 0.0-0.3).
In contrast to the data on factors influencing outcome in established RA, the socioeconomic status variables examined did not explain susceptibility patterns in the population studied.
评估社会经济因素在类风湿关节炎（RA）易感性中的作用。
一项基于人群的炎性关节病前瞻性登记研究（NOAR）在1990年至1992年期间招募了687名成年人，其中50%在就诊时符合美国风湿病学会（ARA）的RA标准。利用人口普查数据，计算了不同社会阶层男女的发病率。进行了相关性分析，以检验发病率与5个社会经济地位指标之间的关联。
发病率没有随着社会阶层的降低而呈现上升趋势。所检查的5个指标均未显示出与发病率有任何关联的证据（相关系数范围为0.0 - 0.3）。
与已确诊RA中影响病情转归因素的数据相反，所研究的社会经济地位变量并不能解释所研究人群中的易感性模式。
