AbstractSeasonal 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.
