Primary Outcome Measures:
  • 6-month change in visceral and subcutaneous abdominal fat

Estimated Enrollment: 56
Study Start Date: June 2001
Study Completion Date: February 2004
Primary Completion Date: February 2004 (Final data collection date for primary outcome measure)
Detailed Description:

Studies on rats and mice have shown that the adrenal hormone dehydroepiandrosterone (DHEA) reduces abdominal visceral fat and protects against insulin resistance. This study was done to learn if DHEA replacement therapy decreases abdominal obesity and improves insulin action in humans.

Participants were randomly assigned to receive 50 mg per day of DHEA or a placebo at bedtime for 6 months. Participants underwent magnetic resonance imaging (MRI) and oral glucose tolerance tests at the beginning and conclusion of the study. Other tests included measurements of hormones and lipids.
