Health Insurance Type and Access to the Indian Health Service Before, During, and After Childbirth Among American Indian and Alaska Native People in the United States

Abstract

Background

American Indian and Alaska Native (AI/AN) people in the United States face elevated childbirth-related risks when compared with non-Hispanic white people. Access to health care is a treaty right of many AI/AN people, often facilitated through the Indian Health Service (IHS), but many AI/AN people do not qualify for or cannot access IHS care and rely on health insurance coverage to access care in other facilities. Our goal was to describe health insurance coverage and access to IHS care before, during, and after childbirth for AI/AN birthing people in the United States.

Methods

We analyzed 2016 to 2020 Pregnancy Risk Assessment Monitoring System data (44 states and two other jurisdictions) for 102,860 postpartum individuals (12,920 AI/AN and 89,940 non-Hispanic white). We calculated weighted percentages, adjusted predicted probabilities, and percentage point differences for health care coverage (insurance type and IHS care) before, during, and after childbirth.

Results

Approximately 75% of AI/AN birthing people did not have IHS care around the time of childbirth. AI/AN people had greater variability in insurance coverage and more insurance churn (changes in type of insurance, including between coverage and no coverage) during the perinatal period, compared with non-Hispanic white people. Health care coverage differed for rural and urban AI/AN people, with rural AI/AN residents having the lowest prevalence of continuous insurance (60%).

Conclusion

AI/AN birthing people experience insurance churning and limited access to IHS care during the perinatal period. Efforts to improve care for AI/AN birthing people should engage federal, state, and tribal entities to ensure fulfillment of the trust responsibility of the United States and to address health inequities.
