Disparities in early prenatal care and barriers to access among American Indian and white women in North Dakota

PURPOSE: American Indians/Alaska Natives (AI/AN) have received minimal attention in research on determinants of prenatal care access. We sought to gain an understanding of structural and sociocultural determinants of prenatal care access among AI/AN and White women in North Dakota (ND). METHODS: Data were drawn from the 2017 to 2018 North Dakota Pregnancy Risk Assessment Monitoring System (n = 1,166). Late prenatal care was assessed with 2 variables: late prenatal care initiation (>13 weeks gestation) and "Did you get prenatal care as early in your pregnancy as you wanted?" (yes/no). Those not satisfied with timing of prenatal care initiation reported 12 prenatal care barriers (yes/no). Logistic regression estimated odds ratios and 95% confidence internals for late prenatal care among AI/AN and other race/ethnicity women compared to White women. Models included maternal sociodemographic, medical, and behavior factors. Chi-square was used to examine the prevalence of prenatal care barriers by race/ethnicity. FINDINGS: AI/AN women had increased risk of late prenatal care initiation (OR: 1.93, 95%CI: 1.20, 3.09) and were more dissatisfied with timing of prenatal care initiation (OR: 1.73, 95% CI: 1.07, 2.78) compared to White women. AI/AN women reported higher prevalence for 8 of 12 (66%) barriers to care, including lack of transportation. Lack of health insurance was more prevalent among White women than AI/AN women (45%-8.5%; P<.01). CONCLUSIONS: Socioeconomic barriers to prenatal care are more prevalent among AI/AN women. This may be a consequence of systematic separation of AI/AN populations from health care resources. Alternative prenatal care delivery methods and expansion of health insurance may improve prenatal care access in ND.
