Psychological impact and risk factors associated with new onset fecal incontinence

ObjectivesWe aim to evaluate the psychological impact and risk factors associated with new onset FI over 12 years in adults over 18 years for the first time in a population-based study.MethodsParticipants (n = 1775) were a random population sample from Penrith, Australia who responded to a survey in 1997 and completed a 12-year follow-up survey (response rate = 60%). FI was defined as having leakage of stool over the past 12 months. The original and follow-up surveys contained valid questions on demographic, gastrointestinal and psychological symptoms.Results114 (11.4%) reported new onset FI at the 12 year follow-up. People who reported FI at the 12 year follow-up were significantly more anxious and depressed. In terms of baseline risk factors only bloating (OR = 1.3; 95%CI 1.0–1.6, P = 0.026) was an independent predictor of developing new onset FI. However, current bowel symptoms measured at follow-up including less likelihood of < 3 bowel motions a week, increased urgency and mucus were independently associated with having FI at follow-up.ConclusionFI is associated with anxiety and depression. Baseline GI symptoms do not appear to be as important as current bowel symptoms in determining who develops FI.
