Maternal Nativity and Residence in US Territories and Preterm Birth
In this cross-sectional study, maternal territory nativity and residence were associated with preterm birth. Territory residence was associated with a higher risk of preterm birth, regardless of insurance type. Privately insured-individuals in US territories had a higher risk of preterm birth than Medicaid-insured individuals in the mainland. Given differential access to health care, health insurance, and other social exposures between territory and mainland populations, future work should explore causal effects and related policies that may improve birth outcomes in US territories.
