Background: Inhaled steroids are recommended for the treatment of persistent asthma during pregnancy, but their potential effects on intrauterine growth have been inadequately evaluated.
Objective: The purpose of this study was to evaluate the association between maternal use of specific inhaled steroids and inhaled steroid dose during pregnancy and the incidence of infants who are small for gestational age (SGA) and mean birth weight.
Methods: Pregnant asthmatic women being treated with inhaled steroids were enrolled in the study before delivery by their managing allergists.
