Maternal and neonatal outcomes among pregnant women with eating disorders

OBJECTIVES: Eating disorders (ED), most prevalent among women of reproductive age, may negatively impact both maternal and fetal health during pregnancy. However, their effects remain inadequately explored. This study aimed to evaluate the associations between maternal ED and perinatal outcomes. METHODS: A retrospective population-based cohort study of all delivery admissions from 2016 to 2021 was conducted using the United States' Healthcare Cost and Utilization Project-National Inpatient Sample. Pregnancies complicated by maternal ED were identified using ICD-10 codes F50.x. Associations between antenatal ED and adverse maternal and neonatal outcomes were assessed using multivariable logistic regression. Potential confounders adjusted for include baseline maternal demographics and relevant clinical factors. RESULTS: Among 4,337,612 delivery admissions, 1,262 involved an ED diagnosis, with prevalence increasing from 23.9 to 37.6/100,000 (p
