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.

Introduction. A distinctive feature of the modern lifestyle of children and adolescents is insufficient physical activity having a negative effect on their health. We conducted a physical activity survey for 997 schoolchildren and 597 students of the city of Ufa. Results. The results showed that 688 respondents (43.16%) did not do sport outside school or university. 272 people (17.06%) reported jogging and playing sports games on their own. 634 respondents (39.78%) attended sports clubs and sections on a regular basis. The survey demonstrated that physically inactive students and schoolchildren violated daily routine. Such schoolchildren spent significantly more leisure time on television viewing (52.78%) compared to their peers attending sports clubs (41.36%). The percentage of schoolchildren spending much time on the computer among those not doing sport was also higher (58.59% vs 41.47%). The same trend was observed in the students: 36.24% of the students not practicing sport spent most of their leisure time on the computer. Physically active students spent enough time outdoors as compared to those not doing sport (23.40% vs 11.15%). Conclusions. The surveyed schoolchildren and students revealed age and gender differences in sports patterns. The duration of training and the level of sportsmanship was higher in boys than in girls. We also observed the increase with age in the number and duration of training, as well as the level of sportsmanship. The health status analysis showed that the schoolchildren and students doing sport had significantly more harmonious physical development, while disharmonious physical development was more common among physically inactive persons. The pupils and students practicing sport regularly showed higher lung vital capacity, hand muscle strength, and a higher level of adaptation.

Introduction. One of the most important tasks of Medicine at present is to determine the level of physical health of a person, based on an assessment of physical development. Given the urgency of the problem, we conduct a comprehensive hygienic study, the purpose of which was to assess the physical development, as well as the conditions and lifestyle of university students, with the subsequent development of a system of measures aimed at maintaining and strengthening the health of students. Material and methods. The study included 1,820 students from 4 universities of the Ufa city, Republic of Bashkortostan. At the first stage, there was performed an assessment of students’ physical development using certified devices. In the second stage of the research, an anonymous questionnaire was organized, aimed at studying the living conditions and lifestyle of the students. In the third stage, a conceptual model was developed for determining health risk groups depending on the physical development, conditions, and lifestyle of students using neural network technologies, as well as a system of measures aimed at preserving and strengthening the health of students. Results. While assessing the physical development of students, it turned out that only in 74.7% of students the body mass index is within the normal range. One in seven students has an insufficient body weight (15.1%), and one out of ten students is overweight (10.2%). The average dynamometry (grip strength) among young women is 25.6 ± 0.6 kg, among young men - 45.5 ± 0.8 kg. The ranking using percentiles showed that the range of grip strength indices from Р25 to Р75 among young women is 22.0-28.5 kg, among young men - 40.0-52.0 kg. The balance of sympathetic and parasympathetic influences (according to Kerdo index) is typical for 58.6% of students, one out of four students is prone to sympathicotonia (28.4%). The main “time absorber” for modern student youth has been determined: the average time spent on social networks during weekdays was 4.8 ± 0.24 hours. A significant deficit of night sleep among students has been identified. The average duration of students’ night sleep on weekdays was only 6.4 ± 0.27 hours. Only one-sixth students went in for sports (17.5%). Nutrition has changed for the worse after entering a university in 42.8% of respondents. Based on the study, standards for the physical development of Bashkortostan Republic students were developed and approved by the Ministry of Health of the Republic of Bashkortostan. Using the developed conceptual model for identifying risk groups for student health based on neural network tools, in 14.9% of students sympathicotonia were determined to be considered to be at high risk for health. The system of measures aimed at optimizing the learning environment and formation of positive hygienic behavior of students has been justified, developed and implemented. Conclusion. Negative changes in the physical development of young people were identified: a tendency toward asthenization in young people, the decrease (over the years of the study at a University) in the number of students with a body mass index within normal limits, and decrease in strength indices (compared to generations of students from the early 2000s). The results obtained indicate to the need for work aimed at maintaining and strengthening the health of students.

Introduction. Rational nutrition is one of the most important factors of a healthy lifestyle, ensuring the preservation and strengthening of the health of the population. However, in the government document “Fundamentals of the state policy of the Russian Federation in the field of healthy nutrition of the population for the period until 2020” it is noted that despite positive trends in nutrition of the population, the mortality from chronic diseases, the development of which is largely related to the alimentary factor, remains much higher than in most European countries. It is especially important to ensure the rational nutrition of young people, which determines the future development of Russian society. Given the urgency of the problem, we carried out a comprehensive hygienic study aimed at studying the nutrition of students in higher education. Materials and methods. 1820 students from 4 Universities of Ufa of the Republic of Bashkortostan took part in the experiment. The study of the daily diet of students was conducted using the method of 24-hour reproduction. Two computer programs aimed at monitoring of the daily diet of students have been developed, tested and registered. The chemical composition and caloric content of the consumed products was estimated. Results. As a result of the study, the amount of protein in the daily rations of students was found out to increase (for girls - by 8.2%, for boys - by 23.5%). Above the norm, there is also the fat content in food products of young men (by 10.2%). The students of both genders have been diagnosed with carbohydrate deficiency (8.5% below the norm for girls, 10.4% for boys). The daily calorific value of the students was normal. Evaluation of the content of macronutrients in the diet of students revealed excessive intake of sodium (32.7% above the norm for girls and 90.9% for boys), phosphorus (25.1% higher for girls and 65.0 % - for boys). Both girls and boys have a significant calcium deficit: 44.5% and 41.1% lower than the normative indices, respectively. When studying the content of microelements in diets, the girls showed a significant iron deficiency (21.7% below the norm). Deficiency of vitamin C (for girls below the norm by 23.2%, in boys - by 15.2%) was identified. The intake of vitamin B2 is somewhat reduced for female students (by 11.2%). Conclusion. The analysis of the students’ diet revealed a discrepancy with the norms of physiological needs for a number of nutrients. A conceptual medical-pedagogical model aimed at the formation of value orientations towards the healthy lifestyle of students (oriented, among other things, improve the quality of nutrition) has been developed and tested. The analysis of the effectiveness of the medical-pedagogical model is carried out using neural network information technologies that assess the impact of the regime and quality of nutrition on students’ health status.
