Mantel A, et al. - Researchers examined how maternal eating disorders affect adverse pregnancy and neonatal outcomes. All singleton births included in the Swedish Medical Birth Register from January 1, 2003, to December 31, 2014, comprised this population-based cohort study. In this cohort study, they analyzed 2,769 women with anorexia nervosa, 1,378 women with bulimia nervosa, and 3,395 women with an eating disorder not otherwise specified, and compared these with 1,225,321 women without eating disorders. The analysis revealed an association of maternal eating disorders with adverse pregnancy outcomes, such as antepartum hemorrhage, and with adverse neonatal outcomes, such as preterm birth, small size for gestational age, and microcephaly. Women with an active eating disorder had the most pronounced risk of most of these outcomes; however, women with a previous eating disorder also showed significantly increased risk. these results emphasize the significance of considering eating disorders among pregnant women and acknowledging the potential correlation with maternal and neonatal health.
