Overactive Bladder: Prevalence and Implications in Brazil

ObjectivesTo assess overactive bladder (OAB) prevalence, associated factors and implications in a young population.MethodsAn independent population-based study was carried out. A self-applicative questionnaire covering urinary symptoms, coping strategies, quality of life and treatment seeking behavior was developed.ResultsA total of 848 subjects between 15 and 55 years completed the questionnaire. The overall prevalence of OAB was 18.9%. Women were significantly more affected than men (p = 0.001). All age groups were equally affected (p = 0.152). Subjects with OAB reported significant impairment on household chores (p = 0.009), physical activities (p = 0.016), sleep (p < 0.001), work (p < 0.001), social life (p < 0.001) and sexual life (p < 0.001). In addition, OAB individuals present higher prevalence of depression (p = 0.036), anxiety (p < 0.001), shame (p < 0.001) and tiredness (p < 0.001) OAB was independently associated to sexual life impairment (OR = 3.36, 95% CI = 1.20–9.39). Only 27.5% of OAB subjects sought for medical counseling.ConclusionsOAB is a highly prevalent condition, even in such a young population. It affects both genders, yet it is more frequently observed in women. OAB is an important health condition, with serious impact on quality of life and sexual function. A large percentual of individuals remain unrecognized, under treated and consequently suffer for long periods of time.
