The results of the research show the main problems in the development of healthy lifestyle of modern student youth. We made the analysis of day regimen of modern students, identified the assessment of expertise level of balanced diet, found the frequency of use of the information-communication technologies different types for learning and leisure.

For morbidity is assessed the health of the population, which influence the socio-economic conditions and lifestyle factors, conditions and external factors Wednesday, biological conditions and factors, conditions and factors of the system and service health care. In Russia regularly examines the details of medico-demographic aspects of population health, but the necessary activities to enhance the health of the population of the countries of the Middle East hampered by various problems. Purpose - a study of the medico-social aspects of morbidity among adults and children in the Arab countries of the Middle East. Materials and methods. The research of health status of the population and the influence of socio-hygienic factors in Yemen, Iraq and Syria during the period of 2005-2010, studied modern informational materials on this issue. Results-the health status of the population of Yemen, Iraq and Syria is under the constant influence of the complex socio-hygienic factors mostly negative for the high morbidity of population, the low availability of medical assistance and health literacy, poor living conditions, material income. The first 5 places in the structure of morbidity of the population occupy: andnfekcionnye and parasitic diseases (28.3%), diseases of bodies of digestion (26.1%), respiratory (13.7%), circulatory (12.3%), injuries ( 3.6%), accounting for 83.5% of pathology. Total morbidity adult and children population of the countries surveyed the first three places are occupied by respiratory diseases, infectious diseases and diseases of the digestive system. Almost half of the urban population have daccess to primary health services in the countries studied, the inhabitants of the village-only every fourth. This process in the period from 2011 to 2017 years worsened in connection with military actions. Correction of the prevailing situation is possible only with the establishment of peace and the use of preventive recommendations.

Introduction. The use of microorganisms in biotechnological enterprises, agriculture, and forestry can be accompanied by microbial contamination of the environment and have an adverse effect on the human health. The purpose of the research is to develop and put into practice quantitative criteria for the pathogenicity of biotechnological microorganisms as the first stage in assessing their safety. Materials and methods. Lethal dose (LD50) and “threshold” (Limbact) doses, dissemination in internal organs, toxigenicity, and “pathogenicity enzymes” of thirty-three strains of saprophytic, opportunistic and pathogenic bacteria, 250 strains of 10 genera proposed for use in biotechnology, and 11 strains already used as active biopreparation substances were investigated. Results. Based on the criteria for primary sanitary and hygienic assessment, microorganisms were selected into three groups: strains recommended for industrial use; strains at risk of application; strains not recommended for use. Among the studied 250 strains of microorganisms proposed for use in biotechnology, 38.9% did not have pathogenic properties and can be used, 41.0% are conditionally pathogenic and are at risk of use, and 20.1% are not recommended for use in biotechnology due to the presence of pathogenic properties. A study of the pathogenic properties of 11 strains of bacteria that are the part of modern biological products showed that they belong to non-pathogenic microorganisms. Limitations. The development and testing of the criteria for the primary sanitary and hygienic assessment of microorganisms proposed for biotechnology were carried out on a large material (more than 250 strains) with a single exposure to high doses, which did not allow us to assess the specific effects of exposure to strains during long-term exposure and may be the subject of further research. Conclusion. The criteria for the primary sanitary and hygienic assessment of microorganisms proposed for use in biotechnologies include average lethal and “threshold” doses dissemination in internal organs, toxigenicity and activity of “pathogenicity enzymes”. All planned for use in biotechnology microorganisms should be examined for possible pathogenic properties. Biological products used in real time in the national economy contain only saprophytic microorganisms as an active substance. The problem of biosafety should be solved in the direction of studying the specific effect of microorganisms and biological products on the immune system influence and the state of the microcenosis of the body.
