[Characteristics of the macronutrient composition of diet and some somatometric indicators of patients with tuberculosis].

Relevance of the diet to the physiological needs of the organism is an important factor determining the incidence of tuberculosis in the world and effectiveness of its treatment. The need to study actual nutrition and nutritional status is determined by its significant changes in recent decades. Aim: to study the actual nutrition and assess somatometric indicators of the nutritional status of patients with pulmonary tuberculosis in the acute stage. Material and methods. 217 men and 83 women, the average age of 42.9±0.7 years have been examined. Design: cross-sectional (simultaneous) epidemiological study. Research period: 2018. The method of analyzing the frequency of food consumption for the month preceding hospitalization has been applied. The somatometric indicators (height, body weight, waist, hip, shoulder girth) have been analysed, body mass index (BMI) have been determined. Results and discussion. 77.7±2.4% showed non-compliance of the diet energy with the recommended values, an imbalance in diet according to the content of macronutrients was noted in 88.0%, insufficient amount of protein in the diet, taking into account the existing disease, in particular - animal protein was observed in 68.3% of the examined. Excessive intake of fats, including saturated fatty acids took place in 52.0%, cholesterol in 51.0%, as well as insufficient intake of dietary fiber was revealed in 38.7% of the examined. 19.3% had a malnutrition degree 1 (according to BMI), 11.7% had a 2nd degree, and 2% had a 3rd degree, respectively. BMI within normal limits (according to WHO criteria) was recorded in 57.7% of patients. The proportion of patients with overweight and obesity did not exceed 10% (7.3 and 2.0%, respectively). Conclusion. The assessment of the nutritional status of patients suffering from tuberculosis and the identification of the macronutrient imbalance of their diet determine the need for their correction in the organization of therapeutic nutrition.

[Provision of vitamin D in the adult population of Western Siberia: a population-based study].

The results of research in recent years indicate a widespread low intake of vitamin D, its deficiency or lack among the population of many countries around the world. It is of interest to study vitamin D status of the population living at different geographic latitudes and depending on socio-demographic characteristics. The aim of the research is to analyze vitamin D status of the adult population living in the Omsk Region over the age of 18 in different seasons of the year. Material and methods. Evaluation of vitamin D status has been carried out in 818 adult residents (325 men and 493 women) aged 18 to 92 years, the median of age - 49 (35; 63) years. Vitamin D status was determined by the level of [25 (OH) D] in serum by the method of immuno-chemiluminescent or electrochemiluminescent analysis. Design: cross-section (simultaneous) uncontrolled epidemiological study. Research period: 2017, from January to December. Results and discussion. 25.8±1.5% showed optimal vitamin D provision, insufficient vitamin content was found in 32.5±1.6% of studied participants, and deficit in 41.4±1.7%. The median level of 25(OH)D for all subjects was in the suboptimal sufficiency range and amounted to 22.17 (16.5; 30.3) ng/ml. The lowest level of the metabolite has been registered in patients over the age of 80 years - 16.5 (13.2-22.6) ng/ml, at the age of 70-79 years - 19.1 (12.9-26.9) ng/ml. In persons aged 18-60 years, the median concentrations were higher (22.2-24.8 ng/ml) and did not differ in the age groups. Deficiencies of varying degrees were most prevalent in age groups over 80, 70-79, and 50-59 years. Slightly better sufficiency of men compared with women has been revealed (p=0.052). Seasonal differences were found in the nature of vitamin D supply characterized by a deficit state from January to June [median 18.7 (13.9; 23.5) ng/ml] and a state of insufficiency from July to December [median 24.8 (17.8; 32.04) ng/ml]. The dependence of the level of vitamin D status on the number of sunshine days during the periods of 15-90 days preceding blood collection hasn't been established. Conclusion. The problem of insufficiency of vitamin D applies to all age groups of the adult population of the region of Western Siberia, especially those over 70 years of age. For the first half of the year, predominantly deficient states are characteristic, and for the period from July to December - the state of vitamin D insufficiency in the residents.

[HYGIENIC ASSESSMENT OF WORKING CONDITIONS OF EMPLOYEES OF BROADCASTING CENTER].

Hygienic assessment of working conditions of employees of the Omsk Regional Broadcasting Centre was performed on data of the analysis of materials of certification of workplaces. There were examined materials concerning 65 core profile workplaces, where 130 persons, including 35 women work. There was determined health risk for personnel in dependence on working conditions. The staff was noted to be exposed to the adverse impact of the following factors: chemical, physical (noise, general and local vibration, non-ionizing radiation, microclimate, lighting), severity and intensity ofwork. Class working conditions for 13,5% of workplaces on noise, 35.4% on non-ionizing radiation was assessed as a harmful of the first degree. Lightness indices at 78.5% of the workplaces did not meet the requirements of sanitary norms. At 7.7% of the workplaces levels of hardness of labor were assessed as harmful. The impact of such factors as biological, infrasound, ultrasound, ionizing radiation, aerosols with mainly fibrogenic action, was absent, their assessment was not carried out. Working conditions at 83.1% of workplaces were characterized as hazardous, including at 52.3% of the workplaces where there was established hazard class 3.1, at 30.7% of workplaces--Class 3.2. Among all the factors of occupational environment the largest contribution into the overall assessment of working conditions was made by the lightness factor (50.9%) and non-ionizing radiation (20.6%). The most harmful working conditions have been identified for workplaces of the operator of masthead antenna, engineer of radiocommunications, broadcasting and television, electromechanician of television (radiocommunication), (broadcasting), car driver.
