Prenatal healthcare after sentencing reform: heterogeneous effects for prenatal healthcare access and equity

BACKGROUND: High rates of imprisonment in the U.S. have significant health, social, and economic consequences, particularly for marginalized communities. This study examines imprisonment as a contextual driver of receiving prenatal care by evaluating whether early and adequate prenatal care improved after Pennsylvania’s criminal sentencing reform reduced prison admissions. METHODS: We linked individual-level birth certificate microdata on births (n = 999,503) in Pennsylvania (2009–2015), to monthly county-level rates of prison admissions. We apply an interrupted time series approach that contrasts post-policy changes in early and adequate prenatal care across counties where prison admissions were effectively reduced or continued to rise. We then tested whether prenatal care improvements were stronger among Black birthing people and those with lower levels of educational attainment. RESULTS: In counties where prison admissions declined the most after the policy, early prenatal care increased from 69.0% to 73.2%, and inadequate prenatal care decreased from 18.1% to 15.9%. By comparison, improvements in early prenatal care were smaller in counties where prison admissions increased the most post-policy (73.5 to 76.4%) and there was no change to prenatal care inadequacy (14.4% pre and post). We find this pattern of improvements to be particularly strong among Black birthing people and those with lower levels of educational attainment. CONCLUSIONS: Pennsylvania’s sentencing reforms were associated with small advancements in racial and socioeconomic equity in prenatal care.
