Abstract

There were studied: The role of the disease dynamics at the background area in the formation of the risk for childhood morbidity in the study area; the value of indices of the long-term wavelike risk dynamics and the corresponding adaptation process for the identification and classification of mass non-infectious diseases. The waviness dynamics of the children morbidity risk is caused by the wave-like nature of the disease dynamics in the study and background areas. The disease risk level is formed not only by differences in the incidence rates of the background and study areas but also from differences in phases of high and low non-specific resistance of children contingent in these territories. The different character of the dynamics of the risk for the disease and related waviness of the adaptation process among children reflects the existence of differences in exposure to characteristics of local environmental factors in each territory. The average risk of disease, around which there are carried out annual fluctuations risks and phase states of the adaptation process, and the corresponding levels of reactivity and resistance of the body are the result of the absolute magnitude of the impact of local factors on the study area. The average relative risk of the morbidity, around which there are carried out annual fluctuations risks and phase states of the adaptation process is an integral index of the level of mass non-infectious diseases and the degree of severity of the medical and environmental situation, the level of reactivity and work mismatch of the body subsystems of children and the degree of their intensity. This is the measure of the absolute magnitude of the impact of local factors. The waviness to the development of states of high and low resistance is both always an index of antistress activation responses (or non-specifically high resistance state) and relative to the average force of impact factors (for the observed reactivity level). On the basis of the accounting for the level of the risk, there is suggested the classification of infectious diseases, including 1) the background or relatively satisfactory morbidity, 2) mass morbidity with the increased risk, 3) mass incidence of the high-risk, and 4) a mass incidence of the very high risk.
