The present investigation assessed self-esteem effects on biological and subjective chronic stress measures, including cardiovascular parameters, health indicators, and mood. Moderators were examined, including vagal tone and social identity.

Vagal tone moderated the relationship between self-esteem and the chronic stress measure: hair cortisol (p<.05). The high self-esteem group showed lower cortisol, particularly when coupled with high vagal tone. Individuals with low vagal tone had the highest cortisol; for those …

Early life adversity influences later health and may be mediated by psychosocial, affective, and physiological stress and immune factors. We report evidence from MIDUS biomarker project (N = 845, age 34-84, M = 55.09, SD = 11.70) confirming the predicted relationship between early adversity and frequency of diagnosed chronic illnesses (M = 2.8, SD =1.2). Specific psychosocial and physiological variables were tested as mediators. Lifetime (M = .95, SD = 1.5) and daily (M = 12.8, SD = 1.2) discrimination, urinary cortisol (M = 1.1, SD = 1.2 ug/dL), IL-6 (M =2.8, SD = 2.8 pg/mL) (all ps<.001), and …
