ABSTRACT
Correlations of 25-hydroxyvitamin D, or 25(OH)D, serum concentration with the blood levels of total cholesterol (TC), high-density lipoprotein cholesterol, triglycerides (TG), and apolipoprotein E were analyzed in young non-overweight men (n = 40) and females (n = 61) aged 1423 having no excess body mass. The measured variables have been standardized within each of four locality groups. The spearman rank correlation coefficients of 25(OH)D were Rsp = 0.306 (p = 0.017) with TC in females, and Rsp =0.372 (p = 0.018).

Seasonal and geographical variability in blood serum concentration of 25-OHD3 among the residents of the Perm Territory, Komi and Udmurtia Republics (327 subjects in total) were investigated. The mean values of serum 25-OHD3 concentrations in 13-16 years old adolescents vary from 31.1 to 49.6 nmol/l, in adults from 39.7 to 47.7 nmol/l. They are within the range of variation reported in other groups in Russian Federation and North-Western Europe. Seasonal fluctuations of vitamin D content are more expressed in adolescents. The geographical distribution of the measures does not agree with the conventional notion that it has a latitudinal (South-North) variability gradient.
