Political representation and perinatal outcomes to Black, White, and Hispanic people in Georgia: a cross-sectional study.

PURPOSE: Our goal was to estimate differences in perinatal outcomes by racial differences in political representation, a measure of structural racism.

METHODS

We gathered data on the racial composition of county-level elected officials for all counties in Georgia (n = 159) in 2022. We subtracted the percent of non-White elected officials from the percent of non-White residents to calculate the "representation difference," with greater positive values indicating a larger disparity. We linked this to data from 2020-2021 birth certificates (n = 238,795) on outcomes (preterm birth, <37 weeks, low birthweight birth <2500 g, birthweight, hypertensive disorders of pregnancy, cesarean delivery). We fit log binomial and linear models with generalized estimating equations, stratified by individual race/ethnicity and including individual and county covariates.

RESULTS

Median representation difference was 17.5% points (interquartile range: 17.2). A 25-percentile point increase in representation difference was associated with a greater risk of hypertensive disorders of pregnancy [White: adjusted risk ratio (RR): 1.12, 95% confidence interval (CI): (1.05, 1.2), Black: 1.06, 95% CI: (0.95, 1.17), other: 1.14, 95% CI: (1.0, 1.3), Hispanic: 1.19, 95% CI: (1.07, 1.32)] and lower mean birthweight for Black birthing people [adjusted beta -15.3, 95% CI: (-25.5, -7.4)].

CONCLUSIONS

Parity in political representation may be associated with healthier environments.
