EPIDEMIOLOGIC RISK ASSESSMENT OF CHILDREN’S MORBIDITY FROM ENVIRONMENTAL EXPOSURE

The purpose of the work is a comparative characteristic of indicators efficiency of relative epidemiological risk of primary and general incidence in estimating medico-ecological situation and mass non-communicable diseases of the population. To achieve the goals and tasks a retrospective study of the child's incidence in the years 2000-2012 was carried out in the 33 administrative territories of the Irkutsk region based on the statistical reporting (Form №12). The relative risk of primary and general morbidity of all diseases and of 11 separate classes was calculated using regional background incidence rates obtained by the statistics. The intensity degree of medico-ecological situation on the territory was determined by the varied criteria on the basis of sigma - deviations, waviness and tendencies of dynamics development of incidence relative risks in time were revealed by a smoothed method of sliding simple average values for 3 years and according to polynomial approximation of the 5th order. The research was carried out in 5 cities with the developed industry and 5 nonindustrial areas. The analysis of the average, increased and high risk rates of the general and primary diseases incidence of separate classes in children during the considered period on the territory of the industrial cities and nonindustrial areas has shown that we gain a better understanding about a degree of medico-ecological situation intensity in the studied territories when sharing risk indicators of the general and primary incidence. Undulating risk dynamics of general and primary morbidity in the period under review differ depending on the area, the class of illnesses and morbidity. This reflects the particular cyclical fluctuations of states with respect to low and high resistance to the pathogenic factor effects. Joint use of the risk indicators of primary and general child's morbidity is necessary to carry out while analyzing data of social and hygiene monitoring to assess the intensity degree of medical and ecological situation and mass (with higher and high risk levels) non-communicable morbidity.
