[The characteristics of the blood serum lipid composition in northern Selkups]

A representative sample of native Selkup population (161 males and 237 females) aged 20-69 from the Tyumen region of the Russian Federation was examined for blood lipids using standard techniques. Measurement of mean cholesterol in males and females showed it to be 181.2 +/- 9.4 mg/dl and 188.2 +/- 8.5 mg/dl, respectively, that of low-density lipoproteins, high-density lipoproteins made up 112.0 +/- 9.7 mg/dl and 50.3 +/- 3.9 mg/dl for males and 118.4 +/- 9.0 mg/dl, 51.7 +/- 3.4 mg/dl, for females, respectively. Mean triglycerides concentration amounted to 86.1 +/- 7.0 in males against 87.4 +/- 6.7 mg/dl in females. Overall atherogenic index averaged 2.9 +/- 0.3. The findings evidence that northern Selkups (both males and females) have much lower content of blood cholesterol and low-density lipoprotein cholesterol than control populations from Novosibirsk and Moscow.
