We studied the functional state of the cardiovascular system in 997 schoolchildren of Ufa and 597 students of the Bashkir State Medical University with different levels of physical activity. All subjects were divided into 3 groups depending on the level of physical activity: the first group (control) consisted of schoolchildren and students, which do not involve in sports outside the school and university programs, with the lowest physical activity compared with other groups; the second group included persons with an average level of physical activity, who in addition to physical education classes independently engage in physical culture: running, walking, outdoor games and daily morning exercises; the third group consisted of schoolchildren and students regularly engaged in sports clubs and sections, having the highest level of physical activity. The following hemodynamic parameters were calculated: systolic blood volume, minute blood volume, pulse pressure, fatigue coefficient, blood circulation efficiency ratio, Robinson index. The data obtained for each group were subjected to statistical analysis separately for males and females in the age aspect. We have established the positive influence of regular physical education and sports on the metabolic and energy processes in the heart, which in turn leads to an improvement in the main indicators of the cardiovascular system. Thus, among schoolchildren and students regularly engaged in physical culture and sports, significantly lower values of minute blood volume, blood circulation efficiency ratio, endurance coefficient, Robinson index and high values of systolic blood volume, pulse pressure were noted. The presence of reliable direct correlation of the weak degree of physical culture and sports with the majority of studied hemodynamic parameters was revealed.

It was established that 77,72 ± 1,38 % of students have normal nutritional status, 13,50 ± 2,57 % -inadequate nutritional status, and of 8,78 ± 2,70 % - redundant power status. A significant part of the diets account for bakery and confectionery products, at the same time revealed a low consumption of such basic foods as milk and dairy products, meat, fish. The energy value of the diets of the students were below the physiological norms by reducing the income of protein and carbohydrates. Students are also experiencing a shortage of virtually all vitamins and most minerals. It was established that the quality of life of students with different nutritional status differs, girls have reduced quality of life when excess nutritional status, in boys - while insufficient.

The health of employees is an integral part of the human potential of the organization, which has a special dual significance. On the one hand, this is a necessary condition for the realization of other components of human potential; on the other hand, it reflects the quality of the productive and social environment of the organization. The study of the psychosocial aspect of employee health is a relatively new area in the field of occupational medicine. The proposed work explores the psychosocial well-being of workers in industrial enterprises and the factors that determine it. The information base of the research is the results of a sociological survey of workers of four large industrial enterprises of the Republic of Bashkortostan: UMPO, UGOK, VNZM and Bashneft-service NPZ, as well as financial reports of enterprises and information published on their official websites. The general characteristics of enterprises are given, the method of coefficient analysis is used to evaluate their financial and economic well- being. In general, the respondents demonstrate a positive psychosocial well-being: more than 45% of respondents are completely satisfied with their lives, more than 70% of respondents assess their health as good or excellent, more than 60% of respondents do not consider the search for a new job a difficult task. Factor analysis of the psychosocial well-being of workers is performed by two methods: order regression and classification trees. A comparative analysis of the conclusions drawn as a result of the application of these methods showed that some of them coincide, while some of them differ. To select the preferred method, a comparison of the prediction accuracy was made, showing that both methods provide almost the same accuracy. Therefore, the reliable conclusions are those that are obtained using both methods, namely: self-estimation of health deteriorates while aging; men are more optimistic about their health compared to women; with age, the search for a new job is considered as an increasingly difficult task; men show greater satisfaction with life compared to women; the place of work has an effect on a degree of life satisfaction.

It was established that 77,72 ± 1,38 % of students have normal nutritional status, 13,50 ± 2,57 %– inadequate nutritional status, and of 8,78 ± 2,70 % – redundant power status. A significant part of the diets account for bakery and confectionery products, at the same time revealed a low consumption of such basic foods as milk and dairy products, meat, fish. The energy value of the diets of the students were below the physiological norms by reducing the income of protein and carbohydrates.

There was executed the analysis of morbidity and disability rate in workers with occupational diseases (poisoning) of the Republic ofBashkortostan for the periodfrom 2010 to 2014. There is reflected the sectoral distribution of the relative indices of the occupational morbidity. There are selected factors of labor and the labor process, promoting occupational diseases (OD). The leading place in the structure of primary morbidity is held by OD related to physical overload and functional overexertion of certain organs and systems; the second - by diseases associated with exposure to physicalfactors; the third - by diseases from exposure to workplace allergens. This is followed by illness (intoxications) caused by exposure to chemical factors, industrial aerosols. The share of OD from exposure to biological agents and professional tumors in total accounts for about 2.0% of all cases of OD revealed for the first time.

According to official statistics, in the Republic of Bashkortostan (RB) since 1991 there is noted the increase in the number of patients with cystic echinococcosis. In 2012, the number of recorded cases increased by 55.3% if compared with 2007. In the areas of RB, where there was observed the high index of population morbidity rate, there was noted the extensive growth of the infestation in sheep. The analysis of the landscape-climatic and sanitary characteristics of the territory of the RB, as well as population economic activity revealed a definite relationship between them and the spread of echinococcosis. The performed survey of rural residents of RB showed that the population is poorly informed about the factors of transmission and ways of infection by echinococcosis. Out of respondents 73% were wrong in determining factors of transmission of infection, 34% admitted irregularities in the disposal of slaughtering condemned products. Fully correct answers were given only by 9% of respondents. The research of fruitfulness of hydatid bubbles and viability of Protoscolexes revealed that the effect of hot water (t = 90-100 ° C) is effective for disinfecting of invasive origins of larvocysts. Due to the low level of awareness of the population there is needed an active health education work on effective measures to prevent the spread of echinococcosis in RB--the prevention of feeding dogs with raw slaughtering waste and decontamination in the private courtyard slaughtering condemned products with the hot water.

Five hundred and twenty four students aged 17-23 years studying at Bashkirian State Medical University were examined. The quality of life was assessed using the Russian version of the international standard SF- 36 questionnaires. The differences in terms of sex and age groups were detected among students

There was studied the physical development of4550 schoolchildren of the city of Ufa at the age from 8 to 16 years. Almost a third of the students was noted to have disharmonious physical development. The proportion of children with excess of body weight exceeds the proportion of underweight children in 2 times. Modern schoolchildren of middle and senior age groups were established to have higher indices of height and weight in comparison with peers at the end of twentieth century, and in younger schoolchildren the indices are higher than in their peers in 2004.
