THE THEME: assessment of the influence of socio-economic factors on health and demographic indicators.
population of municipalities of the Voronezh region.
the justification of the system of measures aimed at stabilizing the medical-demographic situation at the regional level.
methods of Health Statistics; questionnaire.
the low socio-economic status of the population is set in the territories, depressed at the level of demographic development. The contribution of socio-economic indicators in health and demographic situation has been determined Reliable cause-effect relationships between health and demographic indicators and the level of socio-economic development of the population have been identified.
The purpose of the investigation was in the study of the influence of aerotechnogenic load on children and adolescents as a cause of the occurrence of diseases and exacerbation of the course of the chronic disease. There was performed an analysis of the daily air pollution by nitrogen dioxide, particulate matter, soot, sulfur dioxide, formaldehyde, phenol, nitrogen oxide, carbon monoxide, and appealability for medical aid of children and young people residing in the area with the high level of aerotechnogenic load. In the course of the work the correlation analysis was used in three ways: when the date of appealability for medical care coincided with daily indices of the level of air pollution; with delayed of 1 day (shift of data was carried out for 1 day); with delayed of 2 days (shift of data was carried out for 2 days). The number of examined children's population under the age of 14 years and adolescents up to 17 years accountedfor 7303 children, the study period was 1 year. In the course of the work there was established a causal relationship between the level of air pollution and the appealability of the children for the medical care: the pair correlation coefficients for certain classes of diseases amounted from 0.16 to 0.82. It is revealed that the highest number of requests for medical assistance was established to be accounted for the date following the date after exposure to elevated concentrations of pollutants in ambient air Therefore, the aerotechnogenic load, to which the human body is exposed to throughout life, from childhood can be considered as a stress factor that reduces the compensatory capacities.
65% of the region's population is covered by the complex monitoring and control of environmental factors. Chemical contamination of drinking water with iron, manganese, boron, or nitrates makes a 60% contribution to anthropogenic load. Implementation of the measures of a special urban program could reduce the proportion of the drinking water, which did not meet the hygienic standards by sanitary chemical indicators, in Voronezh from 10.2% in 1999 to 8.5% in 2008 and halve the concentration of manganese and iron.
Climatic factor is most important condition for the formation of public health. Attention to it has increased recently against the background of global and regional climate change. The aim of the study was to investigate the effect of air temperature on population die off in the Voronezh city in the period of fire-related emergencies. Assessment of cause-and-effect relationships between the air temperature and daily death cases s was performed with the help of the method of time series. Correlation analysis showed a statistically significant positive relationship between air temperature and population die off from all causes and from diseases of the circulatory system with a lag of 0, 1, 2, 3 days; respiratory diseases - with a lag of 3 days. With the gain in air temperature by one degree the number of deaths increases by 3%. The results were used in adopt management decisions on minimization risks and potential negative effects on human health.
A questionnaire survey made in different Voronezh population groups suggests that they spend 80 to 90% of time in the enclosed space. The greatest contribution to the chemical load caused by ambient air pollution made by production areas (54.9%) in the adult able-bodied population and by dwelling areas (56.0-86.9%) in children, adolescents, and pensioners. Pollution of ambient air (K = 9.19) is pronounced to a lesser degree than that of the air of office buildings (K = 12.49), which suggests that there are internal contamination sources in the closed space. The results of the questionnaire survey of respondents suggest that 20% suffer from allergic diseases and 7% of them associate these diseases with dwelling area contamination.
The impact of a teaching process on the working capacity of schoolchildren at new-type educational establishments (lycées, colleges), as well as at general educational schools was studied. There was a correlation between the pupils' health status and immunity and the level of educational workload, the air environment of institutional rooms, regimens.
