Age‐related features of the content of substrates of energy metabolism and body mass index in women residing in the Subarctic and Arctic regions of Russia
Abstract Objectives Age is associated with a number of health risks linked to obesity caused by an imbalance in the main energy substrates—fatty acids (FA) and glucose (Glu). Therefore, the objective of this study was to identify age‐related features of the metabolism of fatty acids and Glu, their c...

Therefore, the objective of this study was to identify age‐related features of the metabolism of fatty acids and Glu, their correlations and the relation with the body mass index (BMI) in women of the local Caucasoid population from two northern regions of Russia with different nature, climate, and geography. Methods We examined women aged 21–60 years born and permanently residing in the Subarctic region (SR) and the Arctic region (AR). The participants were divided into three age groups: 21–35, 36–45, and 46–60 years. The levels of FAs, Glu, and triglycerides (TG) in the blood serum were determined by spectrophotometric and gas chromatographic methods; the values of BMI and TyG (triglyceride glucose) index were calculated. To analyze data, we used the descriptive and correlation analyses by nonparametric methods, as well as multiple linear regression analysis. Results With age, the surveyed women demonstrated elevated levels of triglyceride, the majority of the studied fatty acids, BMI and TyG index. For three fatty acids, age‐related changes were noted in one of the regions only: stearic and linoleic acids in the SR, and docosahexaenoic acid in the AR; no significant changes were observed for dihomo‐γ‐linolenic and arachidonic acids. We found elevated Glu levels in women aged 46–60 years residing in the SR. Regional differences were due to higher concentrations of FAs and Glu in the AR. All identified correlations were positive. BMI values were associated with FAs and TG, and in women aged 46–60 years, they were additionally associated with Glu. The latter also correlated with some FAs and TG in this group. TyG index associations with saturated FAs (SFAs) became stronger with age. Conclusions Age has a significant impact on the homeostasis of key energy substrates (Glu, TG, SFAs, monounsaturated FAs), on BMI and TyG index, which are ...
