Data from the Second and Third National Studies of Morbidity Statistics from General Practice, conducted from 1970 to 1972 and 1981 to 1982, respectively, by the General Practice Research Unit of the Royal College of General Practitioners, were analyzed to estimate morbidity rates of RA and examine changes in these rates over time. The age-adjusted annual incidence of RA in females fell from 3.3 to 2.6 cases per 1,000 person-years from 1970 to 1972 and 1980 to 1981; there was no change observed in males. Over the same time interval, there was a rise in age-adjusted period prevalence of RA in both sexes from 6.4 to 7.5 per 1,000 and 2.8 to 3.5 per 1,000 in females and males, respectively. These data, which should be interpreted with caution, confirm a decline in incidence of RA in females and demonstrate an increase in prevalence of RA in both sexes over the past decade.
英国皇家全科医师学院全科医学研究单位分别于1970年至1972年以及1981年至1982年开展了第二次和第三次全国全科医学发病率统计研究，对其数据进行分析以估算类风湿性关节炎（RA）的发病率，并研究这些发病率随时间的变化情况。1970年至1972年以及1980年至1981年期间，女性RA的年龄调整后年发病率从每1000人年3.3例降至2.6例；男性未观察到变化。在同一时间间隔内，两性RA的年龄调整后期间患病率均有所上升，女性从每1000人6.4例升至7.5例，男性从每1000人2.8例升至3.5例。这些数据应谨慎解读，它们证实了女性RA发病率的下降，并表明在过去十年中两性RA的患病率均有所增加。
