Aims: To verify the possible relation between urinary incontinence and lower limbs strength and resistance indicators and the sex influence in this relation.Methods: Cross-sectional and analytical study with nonagenarians and centenarians from “Multiprofessional Attention to the oldest-old” project. Presence of incontinence, the ease to walking and climbing stairs, Timed up and Go test, sex, age, marital status and depression symptoms were the study variables. Descriptive and analytical analysis (chi-square tests, analysis of variance and univariate and sex-adjusted logistic regression) were performed accepting p<0.05.Results: We evaluated 238 oldest-old, 174 women. The ease of walking 400 meters and stand up from a chair and the time during the Timed Up and Go were significant indicators of muscle strength and resistance in the correlation between incontinence and muscle strength and resistance adjusted by sex (respectively, RC=0.832, p=0.011, RC=0.846, p=0.012 and RC=0.352, p=0.002). Sex was the most significantly related to incontinence (RC=0.349, p=0.001) and its presence in the complete model decreased the significance of other variables. Depressive symptoms increase the chance of presenting incontinence in men.Conclusions: Incontinence can be associated with strength and resistance in lower limbs, mainly in women. Strength and resistance exercises focus on lower limbs can be added to traditional and recognized prevention programs to incontinence.
