We compared the prevalence of urinary incontinence by type among white, black, Hispanic and Asian-American women.
The RRISK is a population based cohort study of 2,109 randomly selected middle-aged and older women. Incontinence and other variables were assessed by self-report questionnaires and in person interviews. Labor and delivery and surgical data were abstracted from medical records archived since 1946. Logistic regression was used to estimate the OR with 95% CIs for incontinence while adjusting for covariates.
The age adjusted prevalence of weekly incontinence was highest among Hispanic women, followed by white, black and Asian-American women (36%, 30%, 25% and 19%, respectively, p <0.001). Type of incontinence also differed among groups, with weekly stress incontinence prevalence being 18%, 15%, 8% and 8% (p <0.001), and weekly urge incontinence prevalence being 10%, 9%, 14% and 7% (p <0.001). After adjustment for age, parity, hysterectomy, estrogen use, body mass, menopausal status and diabetes, the risk of stress incontinence remained significantly lower in black (adjusted OR 0.36, 95% CI 0.23-0.57) and Asian-American (adjusted OR 0.54, 95% CI 0.34-0.86) women compared to white women. In contrast, the risk of urge incontinence was similar in black (adjusted OR 1.19, 95% CI 0.79-1.81) and Asian-American (adjusted OR 0.86, 95% CI 0.52-1.43) women compared to white women.
Significant differences in the adjusted risk of stress incontinence among Hispanic, white, black and Asian-American women suggest the presence of additional, as yet unrecognized, risk or protective factors for stress incontinence.
我们比较了白人、黑人、西班牙裔和亚裔美国女性中不同类型尿失禁的患病率。
RRISK是一项基于人群的队列研究，随机选取了2109名中老年女性。通过自我报告问卷和面对面访谈评估尿失禁及其他变量。分娩和手术数据从1946年以来存档的医疗记录中提取。采用逻辑回归分析在调整协变量的情况下估计尿失禁的比值比（OR）及95%置信区间（CI）。
年龄调整后的每周尿失禁患病率在西班牙裔女性中最高，其次是白人、黑人及亚裔美国女性（分别为36%、30%、25%和19%，p<0.001）。不同组间尿失禁类型也存在差异，每周压力性尿失禁患病率分别为18%、15%、8%和8%（p<0.001），每周急迫性尿失禁患病率分别为10%、9%、14%和7%（p<0.001）。在调整年龄、产次、子宫切除术、雌激素使用、体重、绝经状态和糖尿病后，与白人女性相比，黑人女性（调整后OR 0.36，95%CI 0.23 - 0.57）和亚裔美国女性（调整后OR 0.54，95%CI 0.34 - 0.86）压力性尿失禁风险仍然显著较低。相比之下，与白人女性相比，黑人女性（调整后OR 1.19，95%CI 0.79 - 1.81）和亚裔美国女性（调整后OR 0.86，95%CI 0.52 - 1.43）急迫性尿失禁风险相似。
西班牙裔、白人、黑人及亚裔美国女性在调整后的压力性尿失禁风险上存在显著差异，这表明存在尚未被认识到的压力性尿失禁额外风险或保护因素。
