The impact of maternal hyperemesis gravidarum on early childhood respiratory morbidity

Background Lung maldevelopment due to in‐utero events may potentially cause respiratory morbidity during childhood. Maternal nutritional status during pregnancy is critical for lung development. This study is contributing to the understanding of the interplay between maternal nutrition status during pregnancy, fetal lung development and the risk for respiratory diseases in early life. Research Question To investigate the association between maternal hyperemesis gravidarum (HG) during pregnancy and respiratory morbidity in the offspring's early childhood. Study Design and Methods This is a retrospective population‐based cohort study that included all singleton term deliveries at Soroka University Medical Center (SUMC) between 1991 and 2021. Preterm deliveries (
