Constipation: Prevalence in the Portuguese community using Rome IV-Associated factors, toilet behaviours and healthcare seeking.

Abstract

BackgroundChronic constipation (CC) is a major public health condition and CC management remains challenging.ObjectiveWe aimed to evaluate the CC (and subtypes) prevalence in a Southern Europe Mediterranean country using Rome IV criteria, and to assess related factors, toilet and healthcare seeking behaviours.MethodsCross‐sectional epidemiological survey, conducted in general community and representing the Portuguese population according to sex and age. The questionnaire covered bowel habits, factors potentially associated with CC (demographic, health/lifestyle, toilet behaviours) and data regarding healthcare seeking.ResultsFrom the study data of 1950 individuals were analyzed. The answer rate was 68% and 1335 questionnaires were available for calculation. The CC prevalence was 17.8%, with respectively 9.3% of Functional Constipation (FC) and 8.5% of Irritable Bowel Syndrome – subtype constipation (IBS‐C). The likelihood of constipation was significantly higher in younger (OR 1.01; 95% confidence interval [CI], 1.007–1.031), solo (OR 2.48; 95% CI, 1.7–3.47) and low‐income (OR 2.40; 95% CI, 1.77–3.47) individuals. Constipated individuals spent more time at defecation, longer than 5 min (p = 0.001), and had particular toilet behaviours (absence of a morning pattern [p = 0.008], the use of triggers [p = 0.001] and reading/technological material [p = 0.006]) to facilitate the evacuation. Only 39% of affected individuals sought medical advice, mainly IBS‐C patients (p = 0.018).ConclusionChronic constipation seems to impact 1 in each 5 Portuguese. Constipated patients are younger, solo, less active and with low income. They develop a clear toilet behaviour profile. FC and IBS‐C patients assume particular behaviours.
