The purpose of this study was to test whether cesarean delivery before labor and before ruptured membranes is associated with a higher risk of postpartum morbidity than vaginal delivery among women who are infected with human immunodeficiency virus-1 in Latin America and the Caribbean.
Data from a prospective cohort study (National Institute of Child Health and Human Development International Site Development Initiative Perinatal Study) were analyzed. The study population consisted of women who were followed for > or = 6 to 12 weeks after delivery, who had singleton infants, and with a known mode of delivery.
Of 819 enrollees, 697 women met inclusion criteria (299 vaginal deliveries, 260 cesarean deliveries before labor and before ruptured membranes, 138 cesarean deliveries after labor and/or after ruptured membranes); 36 women (5%) had postpartum morbidity (18 major, 18 minor). Mode of delivery was associated with postpartum morbidity (P = .02). Unadjusted odds ratios (95% CIs) for postpartum morbidity according to mode of delivery were cesarean delivery before labor and before ruptured membranes (odds ratio, 1.16 [95% CI, 0.5, 2.7]), cesarean delivery after labor and/or after ruptured membranes (odds ratio, 2.96 [95% CI, 1.3, 6.7]), and vaginal delivery (reference). These results did not differ appreciably with covariate adjustment.
The rate of postpartum morbidity was low. Mode of delivery was associated with postpartum morbidity, possibly reflecting the larger proportion of minor postpartum morbidity events among those with cesarean delivery after labor and/or after ruptured membranes.
本研究旨在检验在拉丁美洲和加勒比地区感染人类免疫缺陷病毒1型的女性中,胎膜破裂前未临产时行剖宫产与经阴道分娩相比,是否具有更高的产后发病风险。
分析一项前瞻性队列研究(美国国立儿童健康与人类发展研究所国际站点发展倡议围产期研究)的数据。研究人群包括产后随访≥6至12周、单胎分娩且分娩方式已知的女性。
819名受试者中,697名女性符合纳入标准(299例经阴道分娩、260例胎膜破裂前未临产时行剖宫产、138例临产和/或胎膜破裂后行剖宫产);36名女性(5%)有产后发病情况(18例为严重发病,18例为轻微发病)。分娩方式与产后发病相关(P = 0.02)。根据分娩方式,产后发病的未调整比值比(95%可信区间)为胎膜破裂前未临产时行剖宫产(比值比,1.16 [95%可信区间,0.5,2.7])、临产和/或胎膜破裂后行剖宫产(比值比,2.96 [95%可信区间,1.3,6.7])以及经阴道分娩(参照)。经协变量调整后,这些结果无明显差异。
产后发病率较低。分娩方式与产后发病相关,这可能反映出临产和/或胎膜破裂后行剖宫产的产妇中轻微产后发病事件的比例较高。
