The aim of the study was to assess (1) the prevalence of colon related symptoms among the elderly and (2) whether different definitions identify different subjects with Irritable Bowel Syndrome. The study was carried out in a random sample of 1119 70-year-old Danes of whom 72% answered a questionnaire concerning colon related symptoms. The number of bowel movements a week ranged from 0 to 21 among men and 1 to 28 among women, 5% limits were at < 3 or > 15 movements a week. The individual symptoms occurred with prevalences between 16 and 25% among men and 27 and 41% among the women. Abdominal pain, distension and borborygmi occurred significantly more often among women than men, whereas no sex difference was found for alternating stool consistency and number of bowel movements. According to the different definitions the prevalence of Irritable Bowel Syndrome varied from 0 to 18% among men and 4 to 32% among women. The subpopulations with Irritable Bowel Syndrome identified by various definitions had less than half of the subjects in common.
（1）老年人中结肠相关症状的患病率；（2）不同的定义是否能识别出不同的肠易激综合征患者。该研究以1119名70岁丹麦人作为随机样本开展，其中72%回答了一份关于结肠相关症状的问卷。男性每周排便次数在0至21次之间，女性在1至28次之间，5%的界限为每周排便次数<3次或>15次。个体症状的患病率在男性中为16%至25%，在女性中为27%至41%。女性出现腹痛、腹胀和肠鸣音的频率明显高于男性，而在粪便稠度交替和排便次数方面未发现性别差异。根据不同的定义，肠易激综合征的患病率在男性中为0至18%，在女性中为4至32%。通过各种定义识别出的肠易激综合征亚组人群中，共同的受试者不到一半。
