The annual incidence of ulcerative colitis in the city of Cardiff was examined over a 20 year period. In the decade 1968-77, the mean annual incidence was 6.4 per 10(5) of the population compared with 6.3 for the period 1978-87. There was no difference in the distribution or extent of the disease between decades or between sexes. This contrasts with the increased incidence of Crohn's disease during the same period. The study included a survey of family practitioners which identified a further 19 patients (11% of the total).
在20年的时间里，对加的夫市溃疡性结肠炎的年发病率进行了调查。在1968 - 1977年这十年间，年平均发病率为每10万人中有6.4例，而1978 - 1987年期间为6.3例。这两个十年间以及不同性别之间，疾病的分布或范围均无差异。这与同期克罗恩病发病率的上升形成对比。该研究包括对家庭医生的一项调查，又发现了19例患者（占总数的11%）。
