The Delaware Healthy Women Healthy Babies Program (HWHB) was developed in response to increasing rates of infant mortality (IMR) and widening racial disparity. The primary aim of this study was to examine birth outcomes of enrolled and non-enrolled black and Hispanic women in the program whose payer was Medicaid. We utilized a retrospective cohort of linked birth certificate and HWHB program participant data during 2011-2015. Our primary outcome variables (dependent variables) of interest included cigarette use, low birth weight, preterm birth and neonatal mortality. We utilized inverse probability of treatment weighting (IPTW) and estimated crude odds ratios (COR) and adjusted odds ratio (AOR) with 95% confidence intervals (CI) using IPTW as a weight variable. HWHB enrolled women were 10% less likely to smoke during pregnancy COR 0.89 (95% CI 0.82-0.96); were 9% less likely to deliver a low birth weight infant (AOR 0.91; 95% CI 0.84-0.99; p = 0.023); were 15% less likely to deliver a preterm infant (AOR 0.85; 0.78-0.92; p < .0001) as compared with non-HWHB women. Infants delivered by HWHB enrolled women had 27% less likelihood (AOR 0.73; 95% CI 0.54-0.98; p = 0.035) of experiencing a neonatal death (i.e., < 28days) as compared with infants of non-enrolled HWHB women. The primary goal of this evaluation was to assess the effectiveness of the HWHB program on modifiable risk factors of IMR among HWHB enrolled and non-enrolled women. We found that HWHB program is a promising practice in improving the outcomes of infants born to participating black and Hispanic mothers.
