[THE INTERRELATION OF BIOLOGICAL AGE OF THE STUDENTS WITH THE INDICES OF BODY MASS, ITS COMPONENTS, AND THE CONSTITUTIONAL TYPE].

The relationship of biological age with the indices of body mass, body composition, and constitutional type was studied in 832 students aged 18­22 years (302 youths and 530 girls). To determine the biological age, the method of V. P. Voytenko (1981) was used that allowed to establish functional class, rate of aging and health condition. It was found that almost half of the students had poor health associated with the accelerated rate of biological aging. A decline in the proportion of active cell mass and an increase in body fat mass was noted. In 40.6% of students with normal values of body mass index, excessive amount of body fat was determined by bioimpedance method. 62.2% of the students with an accelerated rate of biological aging had an increased content of a fat component in the body.

[Influence of sociohygienic factors on the shaping of the nutritional status in children and teenagers].

There was revealed the structure of deteriorations in the nutritional status of schoolchildren in the city: the most of students has normal nutritional status, but there was noted the high prevalence of excessive body weight and obesity among children and teenagers. Risk factors for development of deteriorations of the nutrition state were detected as follows: irrational food regimen, qualitative compartment offood, factors of educational environment, lifestyle. The main role in system of control of the nutritional status in children is referred to the correction of socio-hygienic factors which prove to be the priority ones in the shaping of the nutritional status in students. As the main condition determining the nutrition state of the up-to-date schoolchildren and the quality of their life in the whole the social cultural level of children and adolescents must be regarded as a result of the hygienic education and training in fundamentals of healthy lifestyle. Priority protective factors of the gain in the part of schoolchildren with normal nutritional status (optimalfood regimen, optimal dietary habits, sufficient level of physical activity) laidfrom the child age in conditions of the family, sufficient level of the physical activity and the implementation of the other element of hygienically expedient day regimen served as the base for the elaboration of the system of the control of nutritional status. Algorithm of the control of the nutritional status in the students of educational institutions includes the creation of healthcare educational environment, optimization of nutrition and physical activity, the shaping of the culture of healthy lifestyle, health-improving measures for children with disorders of nutritional status and their psychological pedagogical supports at the stage of the correction of the nutritional status, improvement of the medical service for the early detection of deviations of nutritional status with the estimation of the efficiency of the system ofpreventive and health-improving measures.
