Restrictive sub-federal immigration policy climates and very preterm birth risk among US-born and foreign-born Hispanic mothers in the United States, 2005–2016

Abstract Immigration policy climate may have pervasive effects on the health of immigrants and their families. We examine how living in a state at the time of delivery with a more restrictive immigration policy climate impacts risk of very preterm birth (VPTB) among Hispanic mothers in the United States. We used data from the United States live birth files, 2005–2016. We fit generalized linear mixed models predicting VPTB including information on individual (e.g., age, parity, specific Hispanic origin group) and geographic (e.g., county level poverty, ethnic density) risk determinants. Living in a state with a more restrictive immigration policy climate is associated with a slight increase in odds of VPTB for Hispanic women (aOR: 1.07 (1.04–1.10)).
