Association of dehydroepiandrosterone sulfate, body composition, and physical fitness in independent community-dwelling older men and women.
Journal of the American Geriatrics Society 1998 March
OBJECTIVES: To determine the association of dehydroepiandrosterone sulfate (DHEAS), body composition, and physical fitness in independent community-dwelling men and women aged 60 to 80 years.
DESIGN: Cross sectional analysis.
PARTICIPANTS: Independent men and women, 60 years of age and older, living in urban and suburban communities of Southeastern Wisconsin.
MEASUREMENTS: History, physical examination, physical activity level, and anthropometrics were measured for every subject. Total adipose mass (TAM) and lean body mass were measured using dual energy X-ray absorptiometry. Dehydroepiandrosterone sulfate, insulin-like growth factor-1 (IGF-1), total testosterone (TT), and free testosterone (FT) were measured using radioimmunoassay. Physical fitness was measured as VO2max using exercise stress tests. Blood for lipids was analyzed using standard assays.
RESULTS: In men, the DHEAS was significantly correlated to age (r = -.32), TAM (r = -.27), percent fat (r = -.30), HDL cholesterol (r = .34), TT (r = .30), VO2max (r = .23), and percent lean body mass (% LBM) (r = .33). In women, the DHEAS was not significantly correlated to any of the variables examined except body mass index (BMI) (r = .23). In men, after partialling out age, DHEAS was significantly correlated to HDL, % fat, TAM, % LBM, and TT. Multivariate analysis for men revealed that high density lipoprotein cholesterol (HDL) was the strongest predictor of serum DHEAS level, followed by % LBM, BMI, and age. The men in the highest quartile of serum DHEAS levels were different from those in the lowest quartile in terms of age, TT, FT, % fat, TAM, % LBM, HDL, and low density lipoprotein (LDL) cholesterol level. No such differences were found in the two groups of women.
CONCLUSION: In this group of independent community-dwelling older men, several factors were found to be associated with the serum DHEAS concentration, whereas in a group of older women, no such associations were identified with the exception of BMI. Men in the highest quartile of serum DHEAS level, compared with those with a serum DHEAS level in the lowest quartile, were younger, leaner, more fit, had higher TT and FT levels, and had a favorable lipid profile. No such differences were identified between the women in the highest and the lowest quartiles of serum DHEAS level.
