Inequities in Availability of Evidence-Based Birth Supports to Improve Perinatal Health for Socially Vulnerable Rural Residents.

Rural residents in the United States (US) have disproportionately high rates of maternal and infant mortality. Rural residents who are Black, Indigenous, and People of Color (BIPOC) face multiple social risk factors and have some of the worst maternal and infant health outcomes in the U.S. The purpose of this study was to determine the rural availability of evidence-based supports and services that promote maternal and infant health. We developed and conducted a national survey of a sample of rural hospitals. We determined for each responding hospital the county-level scores on the 2018 CDC Social Vulnerability Index (SVI). The sample's ( = 93) median SVI score [IQR] was 0.55 [0.25-0.88]; for majority-BIPOC counties ( = 29) the median SVI score was 0.93 [0.88-0.98] compared with 0.38 [0.19-0.64] for majority-White counties ( = 64). Among counties where responding hospitals were located, 86.2% located in majority-BIPOC counties ranked in the most socially vulnerable quartile of counties nationally (SVI ≥ 0.75), compared with 14.1% of majority-White counties. In analyses adjusted for geography and hospital size, certified lactation support (OR 0.36, 95% CI 0.13-0.97), midwifery care (OR 0.35, 95% CI 0.12-0.99), doula support (OR 0.30, 95% CI 0.11-0.84), postpartum support groups (OR 0.25, 95% CI 0.09-0.68), and childbirth education classes (OR 0.08, 95% CI 0.01-0.69) were significantly less available in the most vulnerable counties compared with less vulnerable counties. Residents in the most socially vulnerable rural counties, many of whom are BIPOC and thus at higher risk for poor birth outcomes, are significantly less likely to have access to evidence-based supports for maternal and infant health.
