Does prevalence and correlate of irritable bowel symptoms in a New Zealand birth cohort? Context: To determine the prevalence and correlates of bowel symptoms and the irritable bowel syndrome (IBS) in a birth cohort of young New Zealanders. Participants in the Dunedin Multidisciplinary Health and Development Study at age 26 completed a validated Bowel Disease Questionnaire expressing their experience of clearly defined symptoms over the previous 12 months. 980 participants (499 male, 481 female, comprising 96% of the birth cohort) completed the questionnaire. Sixty four per cent had at least one of the measured symptoms; abdominal pain was reported in 46.5%, chronic constipation in 9.1%, and chronic diarrhoea in 17.1%. A diagnosis of IBS could be made by using two or more of Manning's diagnostic criteria in 18.8%, three or more criteria in 10.3%, and more than three in 3.3%. Symptoms were more than twice as frequent and severe in females than males.
