INFLUENCE OF ENVIRONMENTAL FACTORS ON HYGIENE PREVALENCE OF CIRCULATORY DISEASES OF POPULATION OF THE PRIMORSKY KRAY BIOCLIMATIC ZONES

Abstract

The article presents the results of the environmental and hygienic assessment of the prevalence of diseases of the circulatory system in the adult population in the Primorsky Kray. The analysis was conducted on the incidence of Form 12 for the period of 1991-2011. To characterize the habitat 8 sanitation (according to the Form 18 provided by Center of Hygiene and Epidemiology in the Primorsky Kray) and 7 climatic factors of the modular that were formalized in a 5-point scale based on the developed normalized rating scale were taken. Each module consisted of a factor of 3 to 10 parameters of the environment. To establish the connection between environmental factors and the level of circulatory diseases we used regression analysis of the statistical package SSP. It was revealed that for the last 6 years for the first time the disease circulatory system in the adult population began to occupy first place in the structure of the entire morbidity and reached 43-49 %. Ranging of the administrative territories of Primorsky Kray as habitat and morbidity. With the use of Pearson (χ²) and regression analysis the patterns of environmental factors impacting on the level of cardiovascular diseases were determined. The prevalence of cardiovascular diseases in the adult population of the region depends on the bioclimatic zones, the degree of environmental stress of the situation and factors of the environment. The prevalence of cardiovascular diseases in adults as the organism's response to the impact of the environment influenced primarily hygienic parameters: the level of pollution of the atmospheric air, characterization of chemical pollution and adverse physical factors in urban and rural areas, transport load as well as the level of diseases of the circulatory system has a strong connection with climatic parameters: the number of days with BASR, latitude, speed of air movement.
