Abstract

CONTEXT: Dehydroepiandrosterone (DHEA) and T hormones are advertised as antiaging, antiobesity products. However, the evidence that these hormones have beneficial effects on adipose tissue metabolism is limited. OBJECTIVE: The objective of the study was to determine the effect of DHEA and T supplementation on systemic lipolysis during a mixed-meal tolerance test (MMTT) and an iv glucose tolerance test (IVGTT). DESIGN: This was a 2-year randomized, double-blind, placebo-controlled trial. SETTING: The study was conducted at a general clinical research center. PARTICIPANTS: Sixty elderly women with low DHEA concentrations and 92 elderly men with low DHEA and bioavailable T concentrations participated in the study. INTERVENTIONS: Elderly women received 50 mg DHEA (n = 30) or placebo (n = 30). Elderly men received 75 mg DHEA (n = 30), 5 mg T (n = 30), or placebo (n = 32). MAIN OUTCOME MEASURES: In vivo measures of systemic lipolysis (palmitate rate of appearance) during a MMTT or IVGTT. RESULTS: At baseline there was no difference in insulin suppression of lipolysis measured during MMTT and IVGTT between the treatment groups and placebo. For both sexes, a univariate analysis showed no difference in changes in systemic lipolysis during the MMTT or IVGTT in the DHEA group and T group when compared with placebo. There was no change in the results after adjusting for the resting energy expenditure, except for a small, but significant (P = .03) lowering of MMTT nadir palmitate rate of appearance in women who received DHEA. CONCLUSION: In elderly individuals with concentrations of DHEA (men and women) or T (men) below the normal range for young adults, supplementation of these hormones has no effect on insulin suppression of systemic lipolysis.
