Abstract
Context: Antenatal glucocorticoid (GC) exposure has been discussed as a potent programming factor of hypothalamus-pituitary-adrenal (HPA) axis activity, producing sustained alterations in cortisol secretion throughout life. So far, the assessment of HPA-axis activity in offspring of mothers treated with synthetic GC has been limited to a time period shortly after birth, with prematurity being an important confound in most prior studies. Objective: The present study aimed to investigate HPA-axis reactivity of term-born children with antenatal GC exposure in a larger sample, allowing us to further address sex- and drug-specific effects. Design, Setting, and Participants: This was a cross-sectional study comprised of 209 term-born children between 6 and 11 yr of age. Cortisol secretion patterns in response to a standardized laboratory stressor (Trier Social Stress Test for Children) were assessed in children with antenatal GC exposure (a single course of either dexamethasone or betamethasone) and compared to...
