The aim of this nationwide study was to determine the recent incidence and prevalence of inflammatory bowel disease, i.e., Crohn's disease (CD) and ulcerative colitis (UC), in Japan. We mailed out a preliminary examination sheet with diagnostic criteria, asking about the presence of patients with inflammatory bowel disease, to all hospitals in Japan that have more than 200 beds for general use. The rate of reply was 60.93%. A total of 4243 patients with CD were reported. The incidence per 100 000 population per annum was 0.51 (0.71 in males, 0.32 in females). The prevalence per 100 000 population per annum was 5.85 (7.94 in males, 3.83 in females). Peak age at onset was 20-24 years in males and 15-19 years in females. A total of 12559 cases of UC were reported. The incidence per 100 000 population per annum was 1.95 (2.23 in males, 1.68 in females). The prevalence per 100 000 population per annum was 18.12 (18.70 in males, 18.17 in females). Peak age at onset was 20-24 years in males and 25-29 years in females.
这项全国性研究的目的是确定日本炎症性肠病，即克罗恩病（CD）和溃疡性结肠炎（UC）的近期发病率和患病率。我们向日本所有拥有200张以上普通病床的医院邮寄了一份附有诊断标准的初步检查表，询问炎症性肠病患者的情况。回复率为60.93%。共报告了4243例克罗恩病患者。每年每10万人口的发病率为0.51（男性为0.71，女性为0.32）。每年每10万人口的患病率为5.85（男性为7.94，女性为3.83）。男性发病高峰年龄为20 - 24岁，女性为15 - 19岁。共报告了12559例溃疡性结肠炎病例。每年每10万人口的发病率为1.95（男性为2.23，女性为1.68）。每年每10万人口的患病率为18.12（男性为18.70，女性为18.17）。男性发病高峰年龄为20 - 24岁，女性为25 - 29岁。
