Incontinência urinária em idosos da estratégia saúde da família: prevalência e fatores de risco

Aims: to determine the prevalence of urinary incontinence and its relation with drug intake, cognition, functionality, falls, level of physical activity and body image in the elderly of the Family Health Strategy of Porto Alegre / RS (FHS/POA).Methods: a cross-sectional analytical study, prospectively collected in a random sample (30 units of FHS/POA). Sociodemographic, anthropometric and health data were collected, including on physical activity (Minnesota Physical and Leisure Activity Questionnaire), cognition (Mini Mental State Examination), body image satisfaction (Stunkard Silhouettes Scale) and functional ability (Chair Sit/Stand, hand grip strength and walking speed).Results: a total of 575 elderly subjects (68.9 ± 7.1 years; women = 64.35%) were studied; 33.04% reported urinary incontinence (women = 69.5%). The following parameters were estimated as risk factors for incontinence: lower Mini Exam score (OR= 0,939; p= 0,033; IC95%= 0,887– 0,995), presence of cognitive decline (OR= 1,625; p= 0,010; IC95%= 1,351– 3,113), slower walking speed (OR= 1,160; p= 0,016; IC95%= 1,028– 1,309) and lower chair sit/stand score (OR= 0,013; p= 0,874; IC95%= 0,712 – 0,932). Falls, physical activity, body image satisfaction and medication intake were not significantly associated with UI. Conclusion: in this sample, the prevalence of urinary incontinence was high and presenting weaker lower limb strength, worse mobility and cognition were identified as risk factors for incontinence, all modifiable.
