The purpose of the present study was to investigate the developmental programming part of the theory of biological sensitivity to context using family environmental factors and hypothalamus-pituitary-adrenal (HPA) axis functioning. Specifically, we investigated whether perceived parenting (Rejection and Emotional Warmth) and socio-economic status (SES) predicted basal cortisol levels and the cortisol awakening response (CAR). In a population-based cohort of 1594 adolescents (mean age = 11.08, SD = 0.54) we assessed salivary cortisol, SES and perceived parenting. Perceived parental Emotional Warmth showed an inverse, linear association with basal cortisol levels. In addition, there was a curvilinear relationship between SES and both basal cortisol levels and the CAR. Our findings with regard to basal cortisol levels confirmed our hypothesis: lower basal HPA-axis activity in both high and low SES families compared to intermediate SES families.
