MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prematurity and low birthweight are associated with increased risk of infant mortality as well as increased risk of chronic conditions throughout infancy and into adulthood. Non-Hispanic black infants are twice as likely to be born low birthweight (13.9% vs 7.0%) and 1.5 times as likely to be born prematurely (13.9% vs 9.1%) compared to non-Hispanic white infants.
Under the Affordable Care Act (ACA), states may expand Medicaid to adults with household income levels at or below 138% of the federal poverty level, thus extending coverage to childless adults and improving continuity. Insurance gain may ultimately improve maternal health, increased use and earlier initiation of prenatal care services, and improved access to pregnancy planning resources.
Our study aimed to evaluate whether there were changes in rates of low birthweight and preterm birth outcomes among states that expanded Medicaid versus states that did not expand Medicaid.

Medical Research: What is the background for this study?
Dr. DeFranco: The Infant Mortality Rate in the state of Ohio is higher than many other states. Additionally, there is a large disparity in the IMR with black infants impacted to a higher degree compared to white infants. For this reason, we are particularly interested in identifying factors that contribute to this disparity in order to identify potential areas where public health efforts can be focused.
We know that preterm birth is a major contributor to infant mortality, and that all babies born alive prior to 23 weeks of gestational age, i.e. "previable", die after birth and contribute to the infant mortality rate. In this study, we wanted to assess whether black women are more likely to have early preterm births at less than 23 weeks, and if so whether that may be part of the explanation of why black mothers are at higher risk of experiencing an infant mortality.
Medical Research: What are the main findings?
Dr. DeFranco: In this study, we found that black mothers were more likely to deliver than white mothers at very early preterm gestational ages, less than 23 weeks. We also found that the earlier the delivery, the larger the disparity with black mothers being at higher risk for the earliest deliveries compared to white mothers. From this data, we estimated that in Ohio, 44% of all infant mortality in black mothers is caused by previable preterm birth, whereas only 28% of infant mortality in white mothers is attributed to the same cause. We concluded that very early
