Factor analysis of the odds of having metabolic syndrome in young people with long-term residence in areas considered as the Far North

Introduction. The use of factor analysis in the study of metabolic syndrome (MS) makes it possible to assess the independent effect of each factor and their synergistic effect on the likelihood of developing the disease. Aim. To assess the risk of developing MS in young indigenous and non-indigenous individuals with long-term residence in areas considered to be the Far North. Materials and methods. A case-control study was conducted among 863 young people aged 18–44 years. The study involved 283 men and 580 women, as well as non-indigenous people (583 people) and indigenous people (small peoples of the Far North – Khanty) (280 people) by ethnicity. A one-factor and multifactorial logistic regression analyses of the relationship between factors and the chance of MS in young people in the general sample, by age and ethnicity, were carried out. Results. In all the analyzed groups, the chance of having a MS was significantly associated with an increase in the TyG index and non-high-density lipoprotein cholesterol (non-HDL-C) levels. With an increase in the TyG index by one conventional unit, the chance of MS in the non-indigenous group increased 22-fold, which is 4.7 times higher than in the indigenous group, and with an increase of 1 mmol/L, the non-HDL-C level was 3.4 mmol/L 3-fold higher than in the indigenous group. Conclusion. The TyG index was significantly associated with the odds of having MS, more so than the HOMA-IR index. A significant association was observed with an increase in non-HDL-C levels, predominantly in men (21.4-fold, p < 0.001) and in non-natives (18.7-fold, p < 0.001).
