Key Points Question Is there an association between rates of neonatal Down syndrome diagnosis in states that did vs did not enact 20-week abortion bans from 2011 to 2018? Findings In this cohort study of 31 157 506 births in the United States from 2011 to 2018, the birth prevalence of Down syndrome at birth increased over time, with a significantly higher increase among births in states that enacted a 20-week ban. Meaning This study suggests that abortion bans may inhibit choice in decision-making in the context of second-trimester aneuploidy screening.
