A study of ecological dependence of health indicators of the child population in agricultural region on example of Chernihiv region

Abstract

Objective. Identification of causal relationship between the environment and the level of child health indicators of the agricultural region on an example of Chernihiv region. Materials and methods. The dynamic relationship between the pollution of drinking water, food, air and soil and level of primary and general morbidity in 0-14 years old children, levels of stillbirth, perinatal, neonatal, post-neonatal, infant mortality in 2001-2012 was studied. A cross-correlation analysis with the determination of cross-correlation coefficient (r) and log (Δt), calculated in years, through which most clear changes in indicators of child health due to the action of environmental factors manifest was applied. Results. It was found that the leading factors that have the time-delay impact on the health of the rural child population Chernihiv region are: air pollution, epidemic safety of food, helminthological and bacterial pollution of soil, the quality of drinking water (the sanitary-chemical indicators for centralized water supply; both the sanitary-chemical and sanitary-bacteriological indicators for decentralized water supply). Chemical pollution of soil, bacterial pollution of tap water, radioactive and chemical pollution of food have a delayed impact only on selected indicators of children's health.
