Abstract
Although the literature suggests that women with disabilities are at increased risk for pregnancy complications and adverse birth outcomes, there are few population-based studies of pregnancy outcomes among deaf and hard of hearing (DHH) women in the United States. To compare pregnancy complications and neonatal outcomes between deliveries to DHH and non-DHH women using national hospitalization discharge record data. We used the 2007-2016 Healthcare Cost and Utilization Project National Inpatient Sample to compare pregnancy complications and outcomes among deliveries to DHH women with deliveries to non-DHH women using bivariate and Poisson regressions, controlling for sociodemographic, hospital, and clinical characteristics. DHH women had an increased risk of adverse pregnancy outcomes and chronic medical conditions, including preexisting diabetes (relative risk [RR], 2.01; 95% confidence interval, 1.68-2.42; p<.001), gestational diabetes (RR, 1.31; 95% CI, 1.19-1.44; p<.001), chronic hypertension (RR, 1.51; 95% CI, 1.33-1.72; p<.001), preeclampsia and eclampsia (RR, 1.35; 95% CI, 1.21-1.51; p<.01), placenta previa (RR, 1.62; 95% CI, 1.22-2.16; p<.01), placental abruption (RR, 1.43; 95% confidence interval, 1.15-1.78; p<.01), labor induction (RR, 1.16; 95% CI, 1.05-1.27; p<.01), chorioamnionitis (RR, 1.43; 95% CI, 1.22-1.69; p<.001), cesarean delivery (RR, 1.09; 95% CI, 1.04-1.14; p<.001), premature rupture of membranes (RR, 1.34; 95% CI, 1.20-1.50; p<.001), antepartum hemorrhage (RR, 1.36; 95% CI, 1.13-1.64; p<.001), and postpartum hemorrhage (RR, 1.30; 95% CI, 1.13-1.49; p<.001). After adjustment for socioeconomic and hospital characteristics, the risk for gestational diabetes, preeclampsia and eclampsia, placenta previa, and chorioamnionitis remained unexplained. DHH women are at increased risk for adverse pregnancy, fetal, and neonatal outcomes, illuminating the need for awareness among obstetric and primary care providers as well as the need for systematic investigation of outcomes and evidence-based guidelines.
