In this study, gut functioning and the prevalence of functional bowel disorders among a Wellington community sample of 285 apparently healthy people was estimated using a standardised questionnaire. When asked for their opinion of their bowel functioning generally, 37% of respondents were satisfied that it was always normal, 57.2% regarded it as not always normal, and 5.6% felt it was normal less than half the time or not normal at all. However, only 11.6% had actually consulted a physician about a stomach or bowel disorder in the past year. Average bowel frequency was 8.4 movements per week (SD = 3.9) for the total sample. Approximately three quarters of the total sample had experienced diarrhoea at least occasionally, but only 2.5% half the movements or more often. Constipation was reported by 8.1% for half the time or more, and 1.8% for most bowel movements. Abdominal distension was experienced by 7.2% on half of days or more, and 3.6% on most days or daily. Abdominal pain occuring on six or more separate days in the previous year was reported by 26.4% of men and 31.9% of women. Pain not due to organic disorders that was colonic in nature and of the irritable bowel syndrome type was reported by 15.9% of men and 17.2% of women.
在本研究中，使用标准化问卷对惠灵顿一个由285名表面健康的人组成的社区样本的肠道功能及功能性肠病患病率进行了评估。当被问及他们对自己肠道功能的总体看法时，37%的受访者对其肠道功能一直正常感到满意，57.2%的人认为并非一直正常，5.6%的人觉得正常的时候不到一半或根本不正常。然而，在过去一年中，实际上只有11.6%的人就胃部或肠道疾病咨询过医生。整个样本的平均排便频率为每周8.4次（标准差 = 3.9）。大约四分之三的样本至少偶尔经历过腹泻，但只有2.5%的人半数或更多排便次数如此。报告便秘情况为半数或更多时间的占8.1%，大多数排便都如此的占1.8%。半数或更多天数出现腹胀的占7.2%，大多数日子或每天都出现腹胀的占3.6%。报告上一年中在六个或更多不同日子出现腹痛的男性占26.4%，女性占31.9%。报告有非器质性原因导致的、性质为结肠型且属于肠易激综合征类型疼痛的男性占15.9%，女性占17.2%。
