Associations between adversity in the family of origin and hair cortisol concentration in adulthood

Abstract

AbstractThe current study examined associations between parental adversities as experienced in adolescence and hair cortisol concentration (HCC) 26 years later (n = 47). Specifically, bivariate correlations and linear regressions were used to examine harsh parenting as well as parental economic pressure, emotional distress, and body mass index (BMI) when their adolescent was between 15 and 16 years old (parent average age 43). HCC was measured when the adolescent was an adult (average 42 years old), at a similar age to when their parent(s) first participated in the study. We also assessed their economic pressure, emotional distress, obesity, and perceived stress in adulthood. For results across generations, parental economic pressure experienced during adolescence was significantly related to HCC when these adolescents were adults. None of the adult economic pressure, emotional distress, BMI, and perceived stress variables were associated with their HCC. Interestingly, there were significant associations among adult perceived stress, economic pressure, emotional distress, and obesity. Thus, the association between parental economic pressure and adult HCC is independent of adult adversities. Results highlight early economic adversity as a possible childhood stressor that has implications throughout the life course.
