Birth Tourism Is Associated with Fewer Neonatal Intensive Care Unit Admissions: A Healthy Migrant Effect?

Objective: This work aimed to study perinatal, maternal, and neonatal characteristics of birth tourism (BT) mother-baby dyads and the rate of neonatal intensive care unit (NICU) admissions of BT infants.

Study Design: Retrospective study at a regional perinatal center comparing BT mother-baby dyads to all dyads. BT infants admitted to the NICU were compared with a randomly selected group of infants admitted to the NICU during the same time period.

Results: A total of 1,755 BT dyads were identified over 4 years. BT mothers were older (32 vs. 28 years,  < 0.0001), more likely to carry multiples (5.5 vs. 1.4%,  < 0.0001), deliver via cesarean section (40 vs. 34%,  < 0.0001), and require postpartum intensive care (0.6 vs. 0.1%,  < 0.0001). BT infants had significantly fewer NICU admissions 96 (5.5%) versus 3,213 (11.3%;  < 0.0001). There were no statistically significant differences in NICU course and outcome between BT and non-BT control infants.

Conclusion: Birth tourism is associated with unique determinants of health. In our study, there were fewer NICU admissions, potentially explained by the healthy migrant effect.

Key Points: · Birthright citizenship attracts foreigners to give birth in the United States.. · BT is associated with unique social determinants of health.. · Fewer NICU admissions in our study are possibly explained by the healthy migrant effect..
