To estimate the risk for stress urinary incontinence and pelvic organ prolapse surgery related to vaginal birth or cesarean delivery.
A cohort study of all women having their first and all subsequent deliveries by cesarean (n = 33,167), and an age-matched sample of women only having vaginal deliveries (n = 63,229) between 1973 and 1983. Hazard ratios were calculated using Cox regression models with 95% confidence intervals.
Women only having vaginal deliveries had increased overall risks of incontinence (hazard ratio, 2.9; 95% confidence interval, 2.4-3.6) and prolapse surgery (hazard ratio, 9.2; 95% confidence interval, 7.0-12.1) compared with women only having cesarean deliveries.
Having only vaginal childbirths was associated with a significantly increased risk of stress urinary incontinence and pelvic organ prolapse surgery later in life compared with only having cesarean deliveries.
评估阴道分娩或剖宫产分娩与压力性尿失禁和盆腔器官脱垂手术相关的风险。
对 1973 年至 1983 年间所有初次分娩和所有后续剖宫产分娩的妇女（n=33167）以及仅行阴道分娩的年龄匹配样本（n=63229）进行队列研究。使用 Cox 回归模型计算风险比，并计算 95%置信区间。
与仅行剖宫产分娩的妇女相比，仅行阴道分娩的妇女压力性尿失禁（风险比，2.9；95%置信区间，2.4-3.6）和脱垂手术（风险比，9.2；95%置信区间，7.0-12.1）的总体风险增加。
与仅行剖宫产分娩相比，仅行阴道分娩会显著增加日后发生压力性尿失禁和盆腔器官脱垂手术的风险。
