We conducted a cross-sectional survey in 2005 to determine the prevalence of and factors associated with urinary incontinence (UI) in adults receiving home care. Of the 2,866 patients surveyed, 46% suffered from UI; 6.5% had stress, 16.6% had urge, 9% had mixed, and 17.6% had functional incontinence. No diagnosis regarding type of UI had been established in 50.2%. Factors associated with UI were advanced age, higher body mass index, and impaired mobility. UI is prevalent in older persons receiving home care, but the lack of diagnosis of type of UI in half of the participants surveyed impedes management of UI.
