Abortions performed late in pregnancy are associated with higher death and complication rates, are more expensive, and are emotionally more taxing for patients and staff than abortions performed early in pregnancy. To examine potential correlates of late abortion, we studied 1,066 women having abortions at two Washington, DC, abortion facilities. We found the following variables to be statistically significantly related to the gestational stage of pregnancy at the time a woman seeks an abortion: history of irregular periods, level of education, type and number of pregnancy symptoms volunteered, moral feelings of the women about abortion, confided suspicion of pregnancy to another person, knowledge of the legality of abortion, contraceptive use, pregnancy symptoms elicited by professional personnel, and length of time the sexual partner was known. Yet, these variables are responsible for only a small percentage of the problem, since much variation in gestational age was unexplained by our analysis. This result and the finding that most of the important determinants of delay were individually oriented factors strongly imply that the problem of late abortions is one that will not be greatly influenced by public health interventions.
妊娠晚期进行的堕胎与更高的死亡率和并发症发生率相关,成本更高,对患者和医护人员而言,比起妊娠早期进行的堕胎,在情感上更具压力。为了研究晚期堕胎的潜在相关因素,我们对华盛顿特区两家堕胎机构的1066名堕胎女性进行了研究。我们发现以下变量与女性寻求堕胎时的妊娠孕周在统计学上显著相关:月经不规律史、教育程度、主动提及的妊娠症状类型和数量、女性对堕胎的道德感受、向他人透露怀疑自己怀孕、对堕胎合法性的了解、避孕措施的使用、专业人员引发的妊娠症状,以及认识性伴侣的时长。然而,这些变量仅占该问题的一小部分,因为我们的分析无法解释孕周的大部分差异。这一结果以及大多数导致延迟的重要决定因素都是个体导向因素这一发现,强烈表明晚期堕胎问题不会受到公共卫生干预措施的太大影响。
