BackgroundDeaf and hard-of-hearing (DHH) people are at higher risk than their non-DHH counterparts of experiencing adverse birth outcomes. There is a lack of research focusing on social, linguistic, and medical factors related to being DHH which may identify groups of DHH people who experience more inequity. ObjectiveExamine difference in prevalence of cesarean and adverse birth outcomes among diverse sub-groups of DHH people. MethodsWe conducted a cross-sectional survey of DHH birthing people in the U.S. who gave birth within the past 10 years. The sample was predominantly white, college educated, and married. We assessed cesarean birth and three adverse birth outcomes: preterm birth, low birthweight, and NICU admission post-delivery. DHH-specific variables were genetic etiology of hearing loss, preferred language (i.e., American Sign Language, English, or bilingual), severity of hearing loss, age of onset of hearing loss, and self-reported quality of perinatal care communication. We estimated prevalence, 95 % confidence intervals, and unadjusted prevalence ratios. ResultsThirty-one percent of our sample reported a cesarean birth. Overall, there were no significant differences in prevalence across the outcome variables with respect to preferred language, genetic etiology, severity, and age of onset. Poorer perinatal care communication quality was associated with higher prevalence of preterm birth (PR = 2.37) and NICU admission (PR = 1.91). ConclusionsOur study found no evidence supporting differences in obstetric outcomes among DHH birthing people across medical factors related to deafness. Findings support the important role of communication access for DHH people in healthcare environments.
