Previous studies of racial/ethnic variation in urinary incontinence (UI) suggest that population-specific studies of UI risk factors are needed to develop appropriate public health recommendations. We assessed UI risk factors among postmenopausal Mexican women enrolled in the Mexican Teachers' Cohort.
We conducted a cross-sectional study among 15,296 postmenopausal women who completed the 2008 questionnaire. UI cases were women who reported experiencing UI during menopause. Self-reported potential UI risk factors included age, reproductive variables, smoking status, adiposity, and several health conditions. We estimated multivariate-adjusted odds ratios (ORs) and 95 % confidence intervals (CIs) for UI using multivariable logistic regression.
Among these postmenopausal women, the prevalence of UI was 14 %. Odds of UI were higher among women with ≥4 children vs nulliparous women (OR 1.43, 95 % CI 1.04-1.96) or body mass index (BMI) ≥30 vs <22 kg/m(2) (OR 2.00, 95 % CI: 1.55-2.57). Age at first birth <20 vs 20-24 years, past or current vs never smoking, larger waist-to-hip ratio, and history of asthma, high blood pressure, or diabetes were also associated with higher odds of UI (OR 1.2-1.3). We found a trend of lower odds of UI with older age.
Our data suggest that information about UI and UI prevention strategies might be particularly useful for Mexican postmenopausal women with 4 or more children or higher BMI. Further studies with longitudinal UI data, in addition to data on UI severity and subtype, are needed to provide more specific information about UI risk factors to Mexican women.
