Reduction in Postpartum Uninsurance Among Black Women in Non-Expansion States

A study by Columbia University's Mailman School of Public Health highlights a reduction in postpartum uninsurance among Black women in states that did not expand Medicaid under the Affordable Care Act (ACA). This was observed during the COVID-19 pandemic's continuous Medicaid coverage provision. However, findings published in the American Journal of Preventive Medicine indicate no significant change in racial disparities in insurance coverage between Black and White women.

The research assessed insurance status among postpartum Black and White women, focusing on different Medicaid expansion policies. Dr. Teresa Janevic, associate professor of Epidemiology at Columbia, emphasized the postpartum period's crucial role in addressing maternal morbidity and mortality. The study analyzed insurance coverage changes before and after the COVID-19 continuous coverage policy, considering state Medicaid expansion status.

In 2022, data revealed that Black women experienced higher rates of pregnancy-related complications and mortality than White women, with disparities evident within 12 months postpartum. The American Rescue Plan Act (ARPA) extended Medicaid postpartum coverage to 12 months in 49 states to address these issues. Previously, postpartum uninsurance rates were higher in non-expansion states.

Janevic highlighted that the extended Medicaid coverage policy significantly reduced postpartum uninsurance, especially in non-expansion states. Nonetheless, she warned that this policy alone might not fully address racial disparities in maternal healthcare.

The study utilized data from the American Community Survey (ACS) and U.S. census microdata, analyzing records from 157,016 non-Hispanic Black and White women who recently gave birth. The analysis covered pre-pandemic years (2016-2019) and the period of continuous coverage (2021-2023), considering variables like age, employment, and income. Results underscored Medicaid's critical role in supporting maternal health, particularly for Black women who rely heavily on these services for pregnancy-related care.
