Supply of vitamins A, E and relationship of their levels to saturated fatty acids in adolescent girls of the subartic and arctic regions

The supply of fatsoluble vitamins A and E, special aspects of the fatty acid profile of the saturated series (SFA), intersystem interaction parameters were studied in adolescent girls living in the Subarctic (SR) and Arctic (AR) regions of the European and Asian North of Russia. Regardless of the region of the study, in adolescent girls reduced supply of vitamins A and E was revealed: abnormally low values were recorded in 87.9% and 43.4% of cases in the SR and in 61.9% and 49.2% in AR, respectively. While in AR girls the retinol supply was higher compared to the SR in the presence of higher content of SFA, primarily long- chain, as well as medium-chain hendecanoic, tridecanoic and pentadecanoic acids. With the help of correlation analysis, there were established the feedbacks of the contents of vitamins A and E with SFA in adolescents of SR, and only retinol with SFA in girls of AR.
