Prenatal, Intrapartum and Infant Antibiotic Use and Atopic Diseases in Childhood

This study has the following aims: 1) Assess prenatal, intrapartum and infant antibiotic exposure in relation to atopic dermatitis, allergic rhinitis and asthma. 2) Assess bias due to reverse causality, confounding by early life respiratory infections, and confounding by unmeasured or poorly measured maternal and child factors such as healthcare-seeking behaviors.
