Primary Outcome Measures:
  • Compare carotid artery intima medial thickness [ Time Frame: During study visit ]

Secondary Outcome Measures:
  • Compare metabolic parameters and body composition measurements [ Time Frame: During study visit ]

Enrollment: 24
Study Start Date: June 2008
Study Completion Date: February 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Groups/Cohorts
1
18-25 year old males, growth hormone deficient, who completed growth hormone treatment 3-5 years prior to enrollment in study
2
18-25 year old males, healthy, never treated with growth hormones.

Detailed Description:

Adults with growth hormone deficiency are at risk for cardiovascular disease. What age this begins is not known.

The objectives of this study are to compare the following measurements between growth hormone deficient young males 3-7 years post completion of growth hormone treatment and age related healthy controls:

  1. Carotid artery imaging
  2. Metabolic and cardiac parameters
  3. Body composition measurements
