Abstract

<h4>Objective</h4>Disruptions in the hypothalamic-pituitary-adrenal (HPA) axis are thought to be key neuroendocrine mechanisms involved in psychopathology and may have intergenerational impacts. Hair-derived HPA hormones offer a measure of long-term HPA axis activity that may be useful in assessing maternal and infant health. Building on a community-based randomized control trial of a perinatal depression intervention in Pakistan, we examine intervention effects on HPA axis activity in a subsample of mothers and infants.<h4>Methods</h4>HPA axis activity was assessed using hair-derived cortisol, cortisone, and dehydroepiandosterone (DHEA). Hair samples were collected from mother-child dyads at one year postpartum from 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).<h4>Results</h4>The intervention group had 38 percent <i>(p</i>=0.01) lower maternal cortisol levels and 45 percent (<i>p</i> < 0.01) lower maternal cortisone compared to the EUC group. Maternal DHEA levels were higher among women in the intervention group compared to the EUC group by 29 percent (<i>p</i> = 0.02). Intergenerational intervention effects show higher DHEA levels in infants by 43% (<i>p</i> = 0.03). Infant cortisol and cortisone did not differ across groups.<h4>Conclusions</h4>Results suggest that the perinatal depression intervention has effects on HPA axis activity in both mothers and children, providing evidence that treating maternal depression may impact physiological stress system functioning intergenerationally. In addition, utilizing hair-derived biomarkers of HPA-axis activity is a potentially useful clinical indicator of intervention impacts on the neuroendocrine system.
