目的：为探讨孕前肥胖与剖宫产风险的关系，研究对象为1994年6月1日至1995年5月31日在纽约州中部纽约妊娠20周后分娩的20,130名妇女。在分娩方式方面，将孕前肥胖的妇女与非肥胖妇女进行比较。肥胖的定义是体重指数（BMI）大于29。对整个样本和单胎妊娠且既往无剖宫产史的女性子集进行单独分析，以估计肥胖女性初次剖宫产的风险。统计分析包括卡方检验、粗比值比（OR）和95%可信区间（CI）、校正OR和95% CI，使用logistic回归控制混杂变量。结果：单胎妊娠且无剖宫产史的肥胖妇女进行剖宫产的校正OR为1.64（95% CI 1.46，1.83）。在整个样本中，肥胖妇女接受剖宫产的调整OR为1.66（95%CI 1.51，1.82）。此外，增加体重指数与剖宫产率增加的风险。结论：与非肥胖妇女相比，妇女谁是肥胖的怀孕前是在剖宫产的风险增加。有关饮食和生活方式改变的先入为主的咨询可能会改变这种模式。版权所有（C）1997美国妇产科医师学院。
Objective: To explore the relationship between prepregnancy obesity and the risk for cesarean delivery.Methods: The population studied included 20,130 women with live births after 20 weeks' gestation in central New York state between June 1, 1994, and May 31, 1995. Women who were obese before pregnancy were compared with nonobese women with regard to mode of delivery. Obesity was defined as body mass index (BMI) greater than 29. Separate analyses were conducted on the entire sample and on a subset of women with singleton pregnancies and no prior cesarean deliveries, as an estimate of the risk of primary cesarean delivery in obese women. Statistical analyses included chi(2) test, crude odds ratio (OR) with 95% confidence interval (CI), and adjusted OR with 95% CI, using logistic regression to control for confounding variables.Results: The adjusted OR was 1.64 (95% CI 1.46, 1.83) for obese women with singleton pregnancies and no prior cesarean deliveries to undergo cesarean delivery. The adjusted OR was 1.66 (95% CI 1.51, 1.82) for obese women in the entire sample to undergo cesarean delivery. In addition, increasing BMI was associated with increased risk for cesarean delivery.Conclusion: Compared with nonobese women, women who are obese before pregnancy are at increased risk for cesarean delivery. Preconceptional counseling regarding dietary and Life-style modifications may alter this pattern. Copyright (C) 1997 by The American College of Obstetricians and Gynecologists.
