BT infants admitted to the NICU were compared with a randomly selected group of infants admitted to the NICU during the same time period.  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.  Birth tourism is associated with unique determinants of health. In our study, there were fewer NICU admissions, potentially explained by the healthy migrant effect. · 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.. · 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..While prompt diagnosis of vasculitis is important, recognition of vasculitis mimics is equally essential. As in the case of vasculitis, an approach to mimics based on the anatomic size of vessels can be useful. Infections can mimic vasculitis of any vessel size, including the formation of aneurysms and induction of ANCAs. Genetic disorders and vasculopathies are important considera
