Abstract Low serum dehydroepiandrosterone sulfate (DHEAS) is common in older persons with poor health. The geriatric syndrome of physical frailty is associated with a higher risk of developing fatal and nonfatal health outcomes. However, the association of DHEAS with frailty is uncertain. This study investigated the association of serum DHEAS with frailty and its related adverse outcomes in 416 men and 504 women aged ≥65 years from an Italian prospective population-based cohort study. At baseline, frailty status was defined according to the physical phenotype, and serum DHEAS was measured in a fasting venous blood sample. After 4 years, subjects were reassessed for incident frailty and occurrence of nonfatal frailty-related outcomes (hospital admission, nursing home placement, disability, falls, and fractures). All-cause mortality after 8 years was also recorded. Incident frailty was inversely associated with baseline log-transformed DHEAS in men (odds ratio [OR]=0.35, 95% confidence interval [CI] 0.14-0.88, p=0.026) but not in women. Independent of baseline frailty status, women in the lowest DHEAS quartile compared to the upper three quartiles had a higher risk of hospital admission (OR=0.44, 95% CI 0.21-0.91, p=0.027) and nursing home placement (OR=0.27, 95% CI 0.08-0.95, p=0.041). Baseline log-transformed serum DHEAS was also inversely associated with mortality risk, but limited to women with concurrent frailty (hazard ratio [HR]=0.27, 95% CI 0.11-0.68, p=0.005) or preexisting major diseases (HR=0.57, 95% CI 0.33-0.98, p=0.041). These findings suggest that DHEAS is associated with incident frailty in older men and with fatal and nonfatal frailty-related adverse outcomes in older women.

Abstract

Abstract Low serum dehydroepiandrosterone sulfate (DHEAS) is common in older persons with poor health. The geriatric syndrome of physical frailty is associated with a higher risk of developing fatal and nonfatal health outcomes. However, the association of DHEAS with frailty is uncertain. This study investigated the association of serum DHEAS with frailty and its related adverse outcomes in 416 men and 504 women aged ≥65 years from an Italian prospective population-based cohort study. At baseline, frailty status was defined according to the physical phenotype, and serum DHEAS was measured in a fasting venous blood sample. After 4 years, subjects were reassessed for incident frailty and occurrence of nonfatal frailty-related outcomes (hospital admission, nursing home placement, disability, falls, and fractures). All-cause mortality after 8 years was also recorded. Incident frailty was inversely associated with baseline log-transformed DHEAS in men (odds ratio [OR]=0.35, 95% confidence interval [CI] 0.14-0.88, p=0.026) but not in women. Independent of baseline frailty status, women in the lowest DHEAS quartile compared to the upper three quartiles had a higher risk of hospital admission (OR=0.44, 95% CI 0.21-0.91, p=0.027) and nursing home placement (OR=0.27, 95% CI 0.08-0.95, p=0.041). Baseline log-transformed serum DHEAS was also inversely associated with mortality risk, but limited to women with concurrent frailty (hazard ratio [HR]=0.27, 95% CI 0.11-0.68, p=0.005) or preexisting major diseases (HR=0.57, 95% CI 0.33-0.98, p=0.041). These findings suggest that DHEAS is associated with incident frailty in older men and with fatal and nonfatal frailty-related adverse outcomes in older women.
