Early life health adversity and internalizing disorders in the transition from adolescence to adulthood

Abstract

Early life adversity (ELA) and youth chronic health conditions have been examined as separate contributors to psychopathology. However, little work has specifically examined early life health adversity (ELHA) and its association with risk for internalizing disorders. This study seeks to examine the relationship between ELHA and internalizing disorders across adolescence. A sample of 705 Australian mother-youth dyads participated in a prospective longitudinal study. Mothers reported child health indicators at youth ages three-to-four days, six months, and five years and completed a psychiatric interview at 15 years. Youth completed a psychiatric interview, as well as measures of current health status, at age 20. ELHA was positively associated with both youth anxiety and depressive disorders from ages 15 to 20. When independently accounting for the role of (a) current health status and (b) exposure to traditionally conceptualized forms of ELA, these findings remained statistically significant for anxiety but not depressive disorders. ELHA interacted with maternal depression, such that ELHA was only associated with youth depressive disorders in cases where mothers themselves had experienced depression. Routine mental health screenings may be warranted for youth who experience ELHA and their mothers. Pediatric primary care may be an ideal setting for implementing prevention and intervention efforts.
