Objective |
We sought to compare continence system function of black and white women in a population-based sample.
Study Design |
As part of a cross-sectional population-based study, black and white women ages 35-64 years were invited to have pelvic floor testing to achieve prespecified groups of women with and without urinary incontinence. We analyzed data collected from 335 women classified as continent (n = 137) and stress (n = 102) and urge (n = 96) incontinent based on full bladder stress test and symptoms. Continence system functions were compared across racial and continence groups.
Results |
Comparing black to white women, maximal urethral closure pressure (MUCP) was 22% higher in blacks than whites (68.0 vs 55.8 cm H2O, P < .0001). White and black women with stress incontinence had MUCP 19% and 23% lower than continent women. MUCP in urge incontinent white women was as low as stress incontinent whites, but blacks with urge had normal urethral function.
Conclusion |
Black women have higher urethral closure pressures than white women. White women with urge incontinence, but not black women, have reduced MUCP.
