[Prevalence of urinary incontinence and linked factors in men and women over 65]. / Prevalencia de la incontinencia urinaria y factores asociados en varones y mujeres de más de 65 años.

OBJECTIVES: To calculate the prevalence of urinary incontinence and to identify linked factors in a population of elderly people living in their homes. DESIGN: Population survey. SETTING: Leganés (Madrid). PARTICIPANTS: Representative sample of people over 65 registered in Leganés (n=1560). Two interviews at home were conducted. The second interview included a medical examination. The reply rate was 75% (n=1150). MAIN MEASUREMENTS: Frequency of involuntary losses of urine and use of medication and absorbents, health status, use of diuretics and oxybutinin, and demographic and social variables. RESULTS: The prevalence of urinary incontinence was 14% (95% CI, 11%-17%) in men and 30% (95% CI, 26%-34%) in women. Advanced age was associated with greater prevalence in men but not in women. In the multivariate analysis, factors associated with urinary incontinence were comorbidity and cognitive deficit. In addition, in women, high Body Mass Index and seriously limited movement were added factors. 20% of women and 5% of men over 65 used absorbents. The use of diuretics and the low number of patients receiving specific treatment for urinary incontinence suggested that there was low detection of this problem. CONCLUSIONS: Urinary incontinence is common and could be better detected and treated in primary care. Prevention of urinary incontinence in women should begin before old age.
