Participants included individuals who delivered singletons. Data were analyzed from December 2023 to June 2024.<\/jats:p>\n <\/jats:sec>\n \n Exposure<\/jats:title>\n Food insecurity in pregnancy assessed using the validated 2-item Hunger Vital Sign screener.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n Maternal (gestational diabetes, gestational hypertension, preeclampsia, cesarean delivery) and neonatal (preterm birth, neonatal intensive care unit [NICU] admission, small-for-gestational age [SGA], and large-for-gestational age [LGA]) complications extracted from the electronic health records, and a composite adverse perinatal outcome (APO) of maternal and neonatal complications. Modified Poisson regression models were adjusted for covariates and stratified by receipt of food assistance in pregnancy.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Among 19\u202f338 individuals, 2707 (14.0%) reported food insecurity in pregnancy. Individuals with food insecurity in pregnancy had a higher risk of gestational diabetes (adjusted relative risk [aRR], 1.13 [95% CI, 1.01-1.29]), preeclampsia (aRR, 1.28 [95% CI, 1.11-1.49]), preterm birth (aRR, 1.19 [95% CI, 1.02-1.38]), NICU admission (aRR, 1.23 [95% CI, 1.07-1.42]), and APO (aRR, 1.07 [95% CI, 1.02-1.13]) compared with individuals without food insecurity. Among 1471 individuals (7.6%) who received food assistance in pregnancy, associations of food insecurity in pregnancy with perinatal complications were attenuated to the null, except for preeclampsia (aRR, 1.64 [95% CI, 1.06-2.53]). On the contrary, the associations persisted among individuals who did not receive food assistance: gestational diabetes (aRR, 1.20 [95% CI, 1.04-1.37]), preeclampsia (aRR, 1.24 [95% CI, 1.06-1.46]), preterm birth (aRR, 1.23 [95% CI, 1.05-1.46]), NICU admission (aRR, 1.31 [95% CI, 1.12-1.52]), and APO (aRR, 1.12 [95% CI, 1.06-1.18]).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In this cohort study, food insecurity in pregnancy was associated with a higher risk of perinatal complications, and these associations were overall attenuated to the null among individuals who received food assistance in pregnancy. These findings support clinical guidelines of screening for food insecurity in pregnancy and provide evidence to expand food assistance programs that may help improve maternal and neonatal outcomes.<\/jats:p>\n
