Regulation of ghrelin, growth hormone and growth factors at high altitude and their change during ascent to high altitude has not been studied in depth yet. The study includes 33 volunteers (12f) investigated at sea level, 4 days after ascent to 3440m and 14 days after ascent to 5400-5900m.
The investigators hypothesized that during ascent growth hormone levels would increase to compensate for the higher energy needs at high altitude.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
