The prevalence of urinary and fecal incontinence in Canadian secondary school teenage girls: questionnaire study and review of the literature.

Abstract

The purpose of this study was to examine the prevalence of pelvic floor dysfunction and incontinence in the Canadian nulligravid secondary school female teenage population. During the University of Toronto day in 1996, female visitors to the Obstetrics and Gynecology Department booth were asked to complete anonymous pelvic floor and continence questionnaires, which were thoroughly explained to them and completed during their visit. Out of the 332 completed forms, 69% were completed by nulligravid teenagers in secondary school. These students formed our study population. The prevalence of urgency urinary incontinence (UUI) symptoms was 17% and of stress urinary incontinence (SUI) symptoms was 15%. In all candidates these reported symptoms were mild, occurring less than once a week. Occasional minor fecal incontinence (involuntary loss of flatus or fecal staining) was 38%; of these, 92% reported loss of flatus. Major fecal incontinence with loose bowel movements was reported by 3% of the study population. Two girls (1%) reported nocturnal enuresis. Weight directly correlated with SUI symptoms and fecal incontinence, but not with UUI. Fecal incontinence correlated with SUI symptoms (P = 0.0152), but not with UUI. Ten per cent of the study population were sexually active, but sexual activity did not correlate with incontinence problems. Voiding habits were markedly variable: 30% were infrequent voiders (three times or fewer per day). Nocturia was reported by 3%. We concluded that in nulligravid teenage female students minor fecal incontinence appears to be the most common incontinence type; urge incontinence was slightly more common than SUI. Unlike UUI, SUI symptoms were more prevalent with fecal incontinence, which were affected by weight. There appears to be a problem with a high prevalence of poor voiding habits.
