Plasma lipids in two indigenous Arctic populations with low risk for cardiovascular diseases.

The distribution of plasma lipids and their sociodemographic and metabolic correlates were investigated in two Arctic indigenous populations based on two health surveys conducted during 1990-1991 among adults in eight Inuit communities in the Keewatin region of the Northwest Territories, Canada (n = 387), and in four communities in the Chukotka region in the Russian Far North (n = 362). For comparison, data from the Canadian Heart Health Survey were used. The age-sex-specific mean total and low-density lipoprotein (LDL)-cholesterol levels among Inuit in northern Canada either do not differ significantly from the Canadian national population, or, in the case of younger Inuit women, are higher than in Canadians.
