The timing of an abortion (often measured as gestational age) can have important effects on the woman's physical health and on the cost of the procedure. To the authors' knowledge, there has been only one national analysis of the factors associated with the gestational age at abortion, but it employed data from over 20 years ago. The state-specific studies that have explored abortion timing have typically examined the effects of a specific change in abortion regulations. In this study, we employ annual, state-level data covering the 1991-2014 period that measure the frequency of abortions by gestational age. We regress these measures of abortion utilization on policy, economic, demographic, and health care infrastructure characteristics. The estimates indicate that the introduction of state restrictions on Medicaid funding of abortions is associated with a 13% increase in the rate of abortions after the first trimester. We do not find a statistically significant association between parental involvement laws and the rate or percentage of post-first-trimester abortions.
人工流产的时间（通常以孕龄来衡量）会对女性的身体健康和手术费用产生重要影响。据作者所知，仅有一项关于与人工流产孕龄相关因素的全国性分析，但它使用的是 20 多年前的数据。对人工流产时间进行探索的州级研究通常只考察了特定堕胎法规变化的影响。在这项研究中，我们利用了涵盖 1991 年至 2014 年期间的年度州级数据，这些数据按孕龄衡量堕胎的频率。我们将这些堕胎利用度的衡量指标与政策、经济、人口和医疗保健基础设施特征进行回归分析。这些估计表明，州对医疗补助资金用于堕胎的限制的引入与孕早期后堕胎率的增加有关，增加了 13%。我们没有发现父母参与法与孕早期后堕胎的比率或百分比之间存在统计学上的显著关联。
