Key Points<\/p>\n\n\n\n

Question<\/strong>  What is the ratio between pregnancy-related and abortion-related mortality?<\/p>\n\n\n\n

Findings<\/strong>  This cross-sectional study using national data on annual pregnancy-related and abortion-related deaths, the annual number of abortions (3\u202f662\u202f580 abortions), and the annual number of births (14\u202f902\u202f571 births) between 2018 and 2021 found that the ratio between pregnancy- and abortion-related mortality in the study period ranged from 44.3 to 69.6, at least 3 times higher than the ratio of 14.7 calculated using data from 1998 to 2005.<\/p>\n\n\n\n

Meaning<\/strong>  These findings suggest that by taking away the option to end a pregnancy, abortion bans force pregnant people to take on the substantially increased health risks associated with continued pregnancy.<\/a><\/p>\n\n\n\n

Abstract<\/p>\n\n\n\n

Importance<\/strong>  The 2022 Supreme Court decision Dobbs v. Jackson Women\u2019s Health Organization<\/em> and the subsequent legal restrictions to abortion have prompted national discussion about the importance of abortion access for maternal health. A commonly cited statistic in these debates, based on data from 1998 to 2005, is that the risk of death associated with childbirth is approximately 14 times higher than that of abortion.<\/p>\n\n\n\n

Objective<\/strong>  To estimate the ratio of pregnancy-related to abortion-related mortality using updated data (2018-2021), capturing increased detection of maternal death and increased safety of abortion since the original estimate.<\/p>\n\n\n\n

Design, Setting, and Participants<\/strong>  This cross-sectional study included all births (live and stillbirths) and pregnancy-related deaths from the National Vital Statistics System from 2018 to 2021. The number of abortion related deaths was obtained from the Pregnancy Mortality Surveillance System, and the number of abortions was obtained from the Guttmacher Institute. Data were analyzed between February and October 2025.<\/p>\n\n\n\n

Main Outcomes and Measures<\/strong>  Pregnancy-related deaths were identified using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision<\/em> (ICD-10<\/em>) codes A34, O10 to O95, O96, O98 to O99. Pregnancy- and abortion-related mortality ratios were calculated per 100\u202f000 births and abortions, respectively, per year and overall. To calculate the ratio, the pregnancy-related mortality rate per 100\u202f000 births was divided by the abortion-related mortality rate per 100\u202f000 abortions. Sensitivity analyses excluded ICD-10<\/em> codes commonly misclassified as pregnancy related and COVID-19\u2013related deaths.<\/p>\n\n\n\n

Results<\/strong>\u00a0\u00a0During the period between 2018 and 2021, there were 14\u202f902\u202f571 births and 3\u202f662\u202f580 abortions. The mean ratio between pregnancy-related and abortion-related mortality was 69.6 (range, 52.9-105.2). Excluding nonspecific causes of pregnancy-related death, the mean pregnancy- to abortion-related mortality ratio was 52.9 (range, 38.2-74.2). Further excluding COVID-19\u2013related mortality, the ratio was 44.3 (range, 34.5 to 74.2).<\/p>\n\n\n\n

Conclusions and Relevance<\/strong>  This cross-sectional study found that the ratio of pregnancy- to abortion-related mortality from 2018 to 2021 ranged from 44.3 to 69.6, at least 3 times higher than the ratio of 14.7 calculated using data from 1998 to 2005.
