Abstract PURPOSE: We compared the prevalence of urinary incontinence by type among white, black, Hispanic and Asian-American women. MATERIALS AND METHODS: The RRISK is a population based cohort study of 2,109 randomly selected middle-aged and older women. Incontinence and other variables were assessed by self-report questionnaires and in person interviews. Labor and delivery and surgical data were abstracted from medical records archived since 1946. Logistic regression was used to estimate the OR with 95\% CIs for incontinence while adjusting for covariates. RESULTS: The age adjusted prevalence of weekly incontinence was highest among Hispanic women, followed by white, black and Asian-American women (36\%, 30\%, 25\% and 19\%, respectively, p <0.001). Type of incontinence also differed among groups, with weekly stress incontinence prevalence being 18\%, 15\%, 8\% and 8\% (p <0.001), and weekly urge incontinence prevalence being 10\%, 9\%, 14\% and 7\% (p <0.001). After adjustment for age, parity, hysterectomy, estrogen use, body mass, menopausal status and diabetes, the risk of stress incontinence remained significantly lower in black (adjusted OR 0.36, 95\% CI 0.23-0.57) and Asian-American (adjusted OR 0.54, 95\% CI 0.34-0.86) women compared to white women. In contrast, the risk of urge incontinence was similar in black (adjusted OR 1.19, 95\% CI 0.79-1.81) and Asian-American (adjusted OR 0.86, 95\% CI 0.52-1.43) women compared to white women. CONCLUSIONS: Significant differences in the adjusted risk of stress incontinence among Hispanic, white, black and Asian-American women suggest the presence of additional, as yet unrecognized, risk or protective factors for stress incontinence.
