HEALTH STATUS OF CHILDREN POPULATION UNDER INFLUENCE OF THE CHEMICAL COMPOSITION OF DRINKING WATER

Abstract

The aim: To study health status among the children in connection with a prolonged exposure of drinking water from decentralized systems. Materials and methods: The prevalence rates of diseases among children of rural areas were studied according to the statistical reports in Dnipropetrovsk region healthinformation center from 2008 to 2013 using statistical form № 12 (totally 220 reports). The distribution of rural areas in the region was based on the cluster analysis. The horizontal dendrogram showing similarity between the research areas in a multidimensional space. Cluster analysis includes 2 groups of rural districts in Dnipropetrovsk region. Results: It is established that with increase of pH#62; 7.5-7.6 in water of decentralized systems decreased the prevalence in the majority of nosologies: diseases of the blood and hematopoietic organs (rS=0,331; p#60;0,001), musculoskeletal system (rS=-0,174; p#60;0,001), anemia (rS=-0,331; p#60;0,001), congenital anomalies (rS=-0,272; p=0,002) among children population. Conclusions: Among those children, who consumed drinking water from wells with content of some essential trace elements on the limits of MPC: 71% did not suffer from chronic diseases of the circulatory system (Fe >0.144 mg/dm3); 59% did not suffer from the diseases of digestive system (Cu #62;0.089 mg/dm3), and 60% had no congenital abnormalities of circulatory system (Mn #62; 0.099 mg/dm3).
