About

This ambispective cohort study aims to evaluate the effect of high altitudes environment on human's physiological and metabolic markers, specific markers of main human systems, and incidence rate and severity of chronic mountain sickness (CMS).

Full description

Qinghai-Tibet plateau is a high altitudes area with average 3,000-5,000 meters height in China. As the partial pressure of oxygen in inspired air falls with increasing terrestrial elevation above sea level, many physiological variables in human body could be affected by this hypobaric hypoxic environment. Up to date, there are no large scale clinical trials assessing these changes in chinese population. The study here would like to provide the newest medical information on the changes of physiological variables and correlation between specific risk factors in chinese adults living at high altitudes for work purpose.
