Dehydroepiandrosterone sulfate, diseases and mortality in a general aged population

Dehydroepiandrosterone sulfate (DHEAS) was measured in a five-year follow-up study of random persons of three age cohorts (75-, 80-, and 85-years, N=571) in order to investigate its associations with clinical diseases and their risk indicators, as well as its prognostic significance in old age. DHEAS was higher in men (3.1 mu mol/L) than in women (1.9 mu mol/L) in the 75-year age group. It decreased in men up 85 years. Compared to healthy men, DHEAS was lower in men with a history of or manifest vascular diseases, presence of dementia, diabetes mellitus, malignancies and musculoskeletal disorders, bur was Similar in all these disease groups. No differences were found in women. DHEAS did not relate to cardioechographic findings, cardiovascular risk factors or predictors of impaired survival prognosis. After controlling for age. DHEAS tended to be lower in the non-surviving than in the surviving men (2.28 mu mol/L vs 2.65 mu mol/L, p=0.065). After controlling for disease, DHEAS did not predict increased risk of all-cause or cardiovascular mortality during the 5-year follow-up. In this study, gender differences in DHEAS persisted up to the age of 75 years. Low plasma DHEAS appears to be a secondary phenomenon rather than a specific risk indicator of common diseases in old age.
