Urinary incontinence knowledge and attitudes in São Paulo.

Urinary incontinence is a social and hygienic problem that affects 15% to 35% of individuals aged 60 years or older, with an estimated annual cost in the United States of $16 billion. To better understand the effects of misinformation and underestimation of the problem, a study to identify knowledge and attitudes related to urinary incontinence was conducted among 400 community-dwelling residents (55 years of age or older). The instrument covered four knowledge/attitude subject areas: treatment and effects, causes, the relationship between aging and urinary incontinence, and physician/patient discussion regarding urinary incontinence. Interviews were conducted in waiting rooms, shopping centers, subways, and hospital/clinic waiting rooms. One hundred, forty-two people (43% women and 23% men) reported current or previous bladder problems. Only two of the 14 knowledge statements elicited a correct response from the majority (60%) of participants. The percentage of correct answers to the other 12 statements ranged from 23% to 43%. Most people believed that urinary incontinence is an inevitable consequence of aging, and the majority of treatment responses (58%) indicated a lack of knowledge about available treatments. Differences in the percentage of correct responses related to the treatment and causes of urinary incontinence were observed between respondents with varying educational levels (P = 0.001) and between Caucasian and African American respondents (P = 0.001). The results confirm that misinformation about urinary incontinence is common in the general population and that educational interventions are needed if the prevalence of uncontrolled urinary incontinence is to be solved.
