[Study of the effect of migration to high-mountain regions on the blood lipoprotein system]

The effect of regular migration of lowlands residents to highlands on their blood lipoproteins was investigated. As compared to non-migrants, the migrants showed a decrease of serum total cholesterol, a reduction of low density lipoproteins, and an increase of high density lipoproteins. The antiatherogenic changes in blood lipoproteins were correlated with a lower prevalence of ischemic heart disease in migrants.
