title: [HYGIENIC ASSESSMENT OF WATER-SOLUBLE VITAMINS CONTENT IN THE FOOD RATION OF ADOLESCENTS].
abstract: BACKGROUND
  Adequate, balanced nutrition is a precondition for the formation of health of the younger generation. The study of the dietary intake and peculiarities of the chemical composition offood is needed to substantiate measures aimed at the correction of the ration of adolescents.
  
  
  OBJECTIVE
  Hygienic evaluation of the content of water soluble vitamins in foods and the ration of teenage population of the Omsk region. TASKS OF THE STUDY: 1. To determine levels of water-soluble vitamins content in foods forming the basis of the ration of the population the Omsk region. 2. On the base of a study of the actual nutrition of adolescents to determine the levels of water-soluble vitamins consumption. 3. To give a hygienic assessment of adolescent nutrition in the Omsk region in terms of provision with water-soluble vitamins, and to identify priority directions of the alimentary correction of the revealed disorders.
  
  
  METHODS
  The analysis of 389 food samples for the content of water-soluble vitamins (B1, B2, B6, PP C, folic acid) was performed with the use of reversed-phase HPLC high pressure on the Shimadzu LC-20 Prominence detector. The hygienic assessment of the actual nutrition of adolescents aged 13-17 years (sample survey; n = 250; 2012-2014) in the Omsk region was performed by the method of the analysis of food consumption frequency.
  
  
  RESULTS
  There were noted significantly lower concentrations of vitamin B1 and B2 in the studied samples of cereals, bread and vegetables in comparison with reference data. Consumption levels of vitamins B1, B2, PP folic acid in the diet of adolescents in the Omsk region are lower than recommended values. In the structure of nutrition there is not enough milk dairy products--in 82.4 ± 2.4%, fish and sea products in 90.8 ± 1.8% of adolescents.
  
  
  CONCLUSIONS
  The actual nutrition of the adolescent population of the Omsk region is irrational, unbalanced in quantitative and qualitative terms, and does not provide the necessary level of consumption of most important water-soluble vitamins. Priority for the correction nutrients there are B1, B2, folic acid (B0).
