After years of failure to obtain accurate statistics on maternal mortality, the United States noted a sharp increase in its maternal mortality rate with widening racial and ethnic disparities. The 2016 report shocked the nation by documenting a 26 percent increase in maternal mortality from 18.8/100,000 live births in 2000 to 23.8 in 2014. Suggested etiologies of this increase included artifact as a result of improved maternal death surveillance, incorrect use of - codes, healthcare disparities, lack of family support and other social barriers, substance abuse and violence, depression and suicide, inadequate preconception care, patient noncompliance, lack of standardized protocols for handling obstetric emergencies, failure to meet expected standards of care, aging of the pregnant patient cohort with associated increase in chronic diseases and cardiovascular complications, and lack of a comprehensive national plan. While some of the increase in maternal mortality may be a result of improved data collection, pregnancy-related deaths are occurring at a higher rate in the United States than in other developed countries. Some have suggested that the increased maternal mortality is due to limiting women's access to legal abortion. In order to discover effective strategies to improve pregnancy outcomes, maternal mortality must be investigated in an unbiased manner. This review explores the relationship between legal-induced abortion and maternal mortality.
In Finland, where epidemiologic record linkage has been validated, the risk of death from legal induced abortion is reported to be almost four times greater than the risk of death from childbirth. It is difficult to do this comparison in the United States not only because prior induced abortion history is often not recorded for a pregnancy-related death but also because less than one-quarter of the states require health care providers to report abortion deaths for investigation. These omissions are important because mortality risk in pregnancies subsequent to abortion is increased due to abortion-induced morbidities such as preterm birth and abnormal placentation. Legal induced abortion is a root cause of the racial and ethnic disparity noted in maternal mortality. In the United States, the death rate from legal induced abortion performed at 18 weeks gestation is more than double that observed for women experiencing vaginal delivery.
多年来,美国一直未能获得准确的孕产妇死亡率统计数据,现其孕产妇死亡率急剧上升,种族和族裔差异不断扩大。2016年的报告记录了孕产妇死亡率从2000年每10万例活产18.8例增至2014年的23.8例,增长了26%,这令全国震惊。此次增长的推测病因包括孕产妇死亡监测改善导致的人为因素、编码使用不当、医疗保健差异、缺乏家庭支持及其他社会障碍、药物滥用和暴力、抑郁和自杀、孕前保健不足、患者不依从、处理产科紧急情况缺乏标准化方案、未达到预期护理标准、怀孕患者队列老龄化及相关慢性病和心血管并发症增加,以及缺乏全面的国家计划。虽然孕产妇死亡率的部分增长可能是数据收集改善的结果,但美国与妊娠相关的死亡发生率高于其他发达国家。一些人认为孕产妇死亡率上升是由于限制了女性获得合法堕胎的机会。为了找到改善妊娠结局的有效策略,必须以无偏见的方式调查孕产妇死亡率。本综述探讨合法人工流产与孕产妇死亡率之间的关系。
在芬兰,流行病学记录关联已得到验证,据报道合法人工流产导致的死亡风险几乎是分娩死亡风险的四倍。在美国很难进行这种比较,不仅因为与妊娠相关死亡的既往人工流产史往往未被记录,还因为不到四分之一的州要求医疗保健提供者报告堕胎死亡情况以供调查。这些遗漏很重要,因为堕胎后的妊娠因早产和胎盘异常等堕胎引起的发病情况而死亡风险增加。合法人工流产是孕产妇死亡率中种族和族裔差异的根本原因。在美国,妊娠18周时进行的合法人工流产死亡率是经阴道分娩女性的两倍多。
