The epidemiology of ulcerative colitis in Stockholm County over a 25-year period, 1955-79, was investigated. Only definite cases in accordance with specified acceptance criteria were included. There were 1274 cases--681 males and 593 females. The proportion of patients with proctitis, left-sided, and total extent of disease of diagnosis remained constant over the study period, as did the time interval between onset of symptoms and definite diagnosis. The peak incidence in relation to age increased slightly but remained in the 3rd and 4th decade through the study period. The incidence in men over 40 years old increased markedly towards the end of the study.
对1955年至1979年斯德哥尔摩郡25年间溃疡性结肠炎的流行病学进行了调查。仅纳入符合特定纳入标准的确诊病例。共有1274例病例，其中男性681例，女性593例。在研究期间，直肠炎、左侧病变以及疾病诊断为全结肠病变的患者比例保持不变，症状出现至确诊的时间间隔也保持不变。与年龄相关的发病率峰值略有上升，但在整个研究期间仍集中在第三和第四个十年。40岁以上男性的发病率在研究接近尾声时显著上升。
