Abstract:

Objective: To investigate the CMS risk of healthy population in western Yunnan plateau. Methods: CMS risk of healthy
population living at different districts was analyzed in 5 ways: bone density measurement, blood routine examination, hemorheological
analysis, blood biochemistry and immunologic function. Results: The bone density of people gradually increased with elevation. RBC
and Hb gradually increased and blood viscosity increased, the difference was statistically significant（P＜0.05）. Except for TP, Alb
and Glu, other indexes of liver function increased with elevation. Indexes of renal function and myocardial enzymes increased as
altitude rose（P＜0.05）. The TC, TG, LDL-C, APoB level of Dali and Weixi group were significantly lower than those of Shangri-La
group（P＜0.05）, and these were even lower than Deqin group（P＜0.05）. The IgG, IgM, IgA, C3, C4 and CD3+, CD8+ level of Dali
and Weixi group were significantly lower than Shangri- La group（P＜0.05）, and were still lower than Deqin group（P＜0.05）.
Conclusion: The indexes of bone density measurement, blood routine examination, hemorheological analysis, blood biochemistry and
immunologic function of healthy people varied differently, and the CMS risk gradually increased.
