The 25 years of rising cesarean delivery rates in the United States may have finally run their course. In 1989 the rate of 23.8 cesareans per 100 deliveries was not significantly different from 24.7 in 1988, 24.4 in 1987, or 24.1 in 1986. The 1989 primary rate of 17.1 first cesareans per 100 women with no previous cesarean was also not significantly different from 17.5 for 1988, or 17.4 for 1987 and 1986. The percentage of vaginal births after cesarean section per 100 deliveries showed a remarkable rise between 1988 and 1989--from 12.6 percent in 1988 to 18.5 percent in 1989. Data are from the National Hospital Discharge Survey conducted by the National Center for Health Statistics, Centers for Disease Control.
美国剖宫产率持续上升的25年可能终于画上了句号。1989年,每100例分娩中的剖宫产率为23.8例,与1988年的24.7例、1987年的24.4例或1986年的24.1例相比,并无显著差异。1989年,每100名未做过剖宫产的女性中首次剖宫产的比率为17.1例,与1988年的17.5例、1987年和1986年的17.4例相比,也无显著差异。每100例分娩中剖宫产术后阴道分娩的百分比在1988年至1989年间显著上升——从1988年的12.6%升至1989年的18.5%。数据来自疾病控制中心国家卫生统计中心进行的全国医院出院调查。
