Objectives: The aim of these analyses was to examine the association between cortisol, dehydroepiandrosterone sulphate (DHEAS), and the cortisol:DHEAS ratio and mortality.

Design: This was a prospective cohort analysis. Methods: Participants were 4255 Vietnam era US army veterans. From military service files, telephone interviews, and a medical examination, occupational, socio-demographic, and health data were collected. Contemporary morning fasted cortisol and DHEAS concentrations were determined. Mortality was tracked over the subsequent 15 years. The outcomes were all-cause, cardiovascular disease, cancer, other medical mortality and external causes of death. Cox proportional hazard models were tested, first with adjustment for age and then additionally adjusting for a range of candidate confounders. Results: In general, cortisol concentrations did not show an association with all-cause or cause-specific mortality. However, in age- and fully-adjusted analyses, DHEAS was negatively related to all-cause, all cancers, and other medical mortality; high DHEAS concentrations were protective. The cortisol:DHEAS ratio was also associated with these outcomes in both age- and fully-adjusted models; the higher the ratio the greater the risk of death. Conclusions: DHEAS was negatively, and the ratio of cortisol to DHEAS was positively associated with all-cause, cancer, and other medical cause mortality. Further experimental study is needed to elucidate the mechanisms involved in these relationships.
