We sought to compare continence system function of black and white women in a population-based sample.
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.
Comparing black to white women, maximal urethral closure pressure (MUCP) was 22% higher in blacks than whites (68.0 vs 55.8 cm H(2)O, 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.
Black women have higher urethral closure pressures than white women. White women with urge incontinence, but not black women, have reduced MUCP.
我们旨在比较基于人群样本中黑人和白人女性的控尿系统功能。
作为一项横断面基于人群的研究的一部分，邀请年龄在 35-64 岁的黑人和白人女性进行盆底功能测试，以达到有和无尿失禁的预设女性群体。我们分析了根据充盈膀胱压力测试和症状将 335 名女性分为尿控（n=137）、压力性（n=102）和急迫性（n=96）尿失禁的女性的数据。比较了不同种族和尿失禁组之间的控尿系统功能。
与白人女性相比，黑人女性的最大尿道闭合压（MUCP）高 22%（68.0 比 55.8cmH2O，P<.0001）。压力性尿失禁的白人和黑人女性的 MUCP 比尿控女性低 19%和 23%。急迫性尿失禁的白人女性的 MUCP 与压力性尿失禁的白人女性一样低，但黑人女性急迫性尿失禁的尿道功能正常。
黑人女性的尿道闭合压高于白人女性。急迫性尿失禁的白人女性，但不是黑人女性，MUCP 降低。
