Introduction: Disruptions in the hypothalamic-pituitary-adrenal (HPA) axis are thought to be key neuroendocrine mechanisms involved in psychopathology and may have intergenerational impacts.
Objective: We examine the impact of a perinatal psychosocial intervention on mother-child HPA axis activity assessed using hair-derived cortisol, cortisone, and DHEA.
Methods: Hair samples were collected from mother-child dyads at one year postpartum from a subsample of prenatally depressed women randomized to a cognitive-behavioral intervention (n=35 dyads) or to enhanced usual care (n=37 dyads), and from a comparison sample of women who screened negative for depression in pregnancy (n=35 dyads).
Results: The intervention reduced maternal cortisol levels by approximately 38 percent (p=0.01) and maternal cortisone levels by 45 percent (p<0.01). Maternal DHEA levels were higher among women in the intervention group compared to the EUC group, an increase of approximately 29 percent (p=0.02). Intergenerational intervention effects show increased DHEA levels in infants by approximately 43% (p=0.03). Infant cortisol and cortisone did not differ across groups.
Conclusions: This study provides evidence for a causal link between treatment of maternal depression and HPA axis activity in mothers and children. Utilizing hair-derived biomarkers of HPA-axis activity is a potentially useful clinical indicator of intervention impacts on the neuroendocrine system.
