Despite its frequency, abortion remains a highly sensitive, stigmatized, and difficult-to-measure behavior. We present estimates of abortion underreporting for three of the most commonly used national fertility surveys in the United States: the National Survey of Family Growth, the National Longitudinal Survey of Youth 1997, and the National Longitudinal Study of Adolescent to Adult Health. Numbers of abortions reported in each survey were compared with external abortion counts obtained from a census of all U.S. abortion providers, with adjustments for comparable respondent ages and periods of each data source. We examined the influence of survey design factors, including survey mode, sampling frame, and length of recall, on abortion underreporting. We used Monte Carlo simulations to estimate potential measurement biases in relationships between abortion and other variables. Underreporting of abortion in the United States compromises the ability to study abortion—and, consequently, almost any pregnancy-related experience—using national fertility surveys.

美国的堕胎报告：对三项全国生育率调查的评估。

尽管堕胎很常见，但它仍然是一种高度敏感、受到污名化且难以衡量的行为。我们对美国最常用的三项全国生育率调查的堕胎漏报情况进行了估计：全国家庭成长调查、1997 年全国青年纵向调查和全国青少年至成人健康纵向研究。每项调查中报告的堕胎数量与从美国所有堕胎提供者普查中获得的体外堕胎计数进行了比较，并根据每个数据源的可比受访者年龄和时期进行了调整。我们研究了调查设计因素（包括调查模式、抽样框架和回忆长度）对堕胎漏报的影响。我们使用蒙特卡罗模拟来估计堕胎与其他变量之间关系的潜在测量偏差。美国对堕胎的漏报影响了利用全国生育率调查研究堕胎的能力，从而影响了几乎所有与怀孕相关的经历。
