SUMMÀRY:
The purpose of the study was to determine the association between the physical development and calcium, phosphorus and 137Cs radionuclides in the organisms of the children living in the regions affected the Chornobyl nuclear power plant accident.
Material and methods. 520 children, living in Ivankiv and Polissya regions of the Kyiv oblast, were examined. The average age of the schoolchildren was 14.0±0.07 years. The Rohrer index was used as a criterion for the assessment of the state of physical development (PD) of the child. Radiometric, anthropometric, spectrometric, mathematical and statistical methods were used for the study.
Results. Among the examined children, living in the regions affected the Chornobyl nuclear power plant accident, the cases of harmonious PD made up 66.9 %. The cases of disharmonious high PD were detected in 63.95 % of the children in the group with disharmonious PD.
There was no association between the PD of the examined children and the content of general calcium in blood. At the same time, the association was observed between the PD of those children and content of phosphorus in blood. The proportion of hypophosphatemia cases in the groups of the children with harmonious and disharmonious high PD development was statistically higher than the proportion of cases where the content of phosphorus in blood was within the reference range. The content of 137Cs radionuclides and phosphorus in blood was reliably higher in the children with disharmonious low PD than in the children with harmonious and disharmonious high PD. The results of the statistical studies confirm the inverse correlative relationships between the indicators of 137Cs, phosphorus values and PD.
The body weight decrease in the adolescents, living in the areas affected the Chornobyl nuclear power plant accident, is associated with an increase of the content of 137Cs radionuclides in the organism and phosphorus in blood.
Conclusions. The obtained results indicate the negative effect of incorporated 137Cs radionuclides on the PD of child’s organism.
