OBJECTIVE
We calculated incidence rates of urinary incontinence by incontinence frequency and type over 4 years in Asian, black, and white women in the United States.
STUDY DESIGN
Prospective analyses included 76,724 participants aged 37-79 years in the Nurses' Health Study cohorts with no incontinence at baseline.
RESULTS
The 4-year incidence of incontinence at least monthly was higher in white women (7.3/100 person-years) compared with Asian (5.7/100 person-years; P = .003) and black women (4.8/100 person-years; P < .001). The incidence of at least weekly stress incontinence was significantly lower in black compared with white women (0.1 vs 0.8 per 100 person-years; P < .001). The difference between black and white women in the incidence of any incontinence and stress incontinence remained significant after adjusting for known risk factors (P < .001 for both).
CONCLUSION
Urinary incontinence incidence differs by race. Studies to confirm these results and better understand underlying mechanisms are needed.
目的
我们计算了美国亚洲、黑人和白人女性在 4 年内按失禁频率和类型计算的尿失禁发病率。
研究设计
前瞻性分析包括基线时无尿失禁的 76724 名年龄在 37-79 岁的护士健康研究队列参与者。
结果
与亚洲女性（5.7/100 人年；P =.003）和黑人女性（4.8/100 人年；P <.001）相比，白人女性至少每月发生一次尿失禁的 4 年发生率更高（7.3/100 人年）。与白人女性相比，黑人女性每周至少发生一次压力性尿失禁的发生率明显较低（0.1 比 0.8/100 人年；P <.001）。在调整了已知危险因素后，黑人女性与白人女性之间任何类型的尿失禁和压力性尿失禁的发生率差异仍然显著（均<.001）。
结论
尿失禁的发病率因种族而异。需要进行研究来证实这些结果并更好地了解潜在机制。
