Abstract

Objective

Blunted patterns of daily cortisol, an indicator of hypothalamic-pituitary-adrenal (HPA) axis stress response system dysregulation, are implicated in poor health outcomes and racial health disparities. It is unknown how coping—an important, but understudied, component of the stress-health disparities relationship—relates to these biological mechanisms of health.

Methods

This study investigated relationships, including racial differences, between 12 coping strategies and early-day cortisol changes (diurnal cortisol slopes from peak to before lunch) among 700 35–85-year-old Black and White male participants in the National Survey of Midlife Development in the United States (MIDUS) II. Cognitive-oriented (e.g., positive reinterpretation, denial, religious/spiritual) and behavioral (e.g., stress eating, substance use) coping strategies were examined.

Results

Overall, Black and White men used similar coping strategies. Most coping strategies were not associated with men’s cortisol slopes. Religious/spiritual coping was associated with steeper (more robust) cortisol slopes among White (b = − 0.004, t = − 3.28, p = 0.001) but not Black men. Drug use was associated with steeper cortisol slopes among Black (b = − 0.095, t = − 2.87, p = 0.004) but not White men.

Conclusions

This exploratory study increases our understanding of relationships between coping and stress-related biological mechanisms underlying racial health disparities among men in later life. With some notable exceptions, men’s coping strategies were not associated with their diurnal cortisol slopes. This suggests that the coping strategies currently used by older Black and White men may not be important factors, as determinants or intervention targets, in disparities in diurnal cortisol slopes and associated health outcomes among men in this age group.
