[PREVENTION OF ALIMENTARY-DEPENDENT PATHOLOGY IN ADOLESCENTS ON THE BASIS OF HEALTH RELATED QUALITY OF LIFE].

With the aim of the substantiation of hygienic measures for the improvement of the prevention of nutrition-related diseases among adolescents there was performed an analysis of indices of the health-related quality of life, lifestyle features, the character of nutrition and health of adolescents aged of 13-17 years in the territory of the Omsk region (n = 427). The study of the health-related quality of life was performed with the use of the validated Russian-language version ofthe general questionnaire PedsQL-4.0. According to the results of the study there were identified the priority factors influencing the formation of the quality of life of adolescents. The nutrition of adolescents has a significant influence on the formation of quality of life. Among the many parameters that characterize the nutrition, the greatest contribution to the quality of life is made by the factor of "the amount of consumed meat products". The decline in quality of life was noted in adolescents with chronic diseases or disorders of the nutritional status as overweight. There were marked forward-looking possibilities of prevention of nutrition-related diseases on the base of indices of the quality of life, including measures for correction of adolescent nutrition, in-time detection of disturbances of the nutritional status, early diagnosis and treatment of chronic diseases.

[HYGIENIC ASSESSMENT OF THE LIPID COMPONENT IN THE STRUCTURE OF NUTRITION OF STUDENT YOUNG ADULTS].

The actual nutrition of the Omsk University students aged 18-27 years, was studied with the use of the method of the analysis of the frequency of food consumption. There is done quantitative assessment of nutrient consumption related to the fat component of food. There is described the qualitative composition of lipids and its effect on indices of the nutritional status assessed with the use of somatometric, bioelectric impedance and laboratory methods. The nutrition of students is established to be irrational, unbalanced on the lipid component and creates conditions for the formation of diseases with alimentary dietary risk factors. Traditional indices of nutritional status (BMI, W/HR) at this are within the boundaries of normal values, but the composition of the body under the influence of an excess of animal fats with a deficiency of essential polyunsaturated fatty acids is altering that can be diagnosed with the aid of bioimpedance measuring method. There are established correlation relations between the parameters ofconsumption of dietary lipids and indices of the nutritional status in young adults.

[HYGIENIC SUBSTANTIATION OF NUTRITIONAL PREVENTION OF HYPOVITAMINOSIS B9 AND B12 IN THE POPULATION OF THE OMSK REGION].

The aim of the study--the assessment of the prevalence of hypovitaminoses B9 (folic acid) and B12 in the population of the city of Omsk and the determination of the possibility of their nutritional prevention. The subject of study--the adult population (18-59 years). The actual nutrition was studied by method of analysis of the frequency of food consumption. Prevalence of hypovitaminoses B9 and B12 was estimated upon the results of laboratory tests of blood by immunochemiluminiscent methods. Established prevalence of hypovitaminoses B (folic acid) and B12 in the population of the city of Omsk accounted for 63.2 ± 5.8% and 13.2 ± 4.1%, respectively. There was shown the possibility of correction of supply with vitamins by means of regular taking offermented dairy product "Prolacta". The serum content of vitamin B12 after a 2-month course of daily use of the product was increased by 17.8%, and the serum folate content--by 29.1%. The proportion of cases with insufficient content ofvitamin B9 in the experimental group decreased from 80.0 ± 6.8% to 38.7 ± 8.7%.
