Abstract

The goal of the study was to assess the correlation between height and body mass deviations measured with the aid of Z-index in teens and cell component of their peripheral blood. Materials and methods. Apical height was measured in 83 adolescent boys in the course of regular prophylactic medical examination. Z-index was calculated according to WHO Growth Reference, 2007. Cell blood composition was studied with the help of automatic hematologic analyzer. The empiric data was processed statistically using Spearman’s correlation coefficient. Results. The analysis of hematologic parameters correlation with deviations of height and bodymass by Z-index has yielded relationship as follows: moderate positive correlation of Hb concentration with bodymass index Z-index, hematocrite – with bodymass and height Z-index. Besides there is a mild positive correlation of Hb concentration with bodymass Z-index; RBC number with bodymass and height Z-index, MCV – with bodymass and height Z-index. There is no correlation of MCH, MCHC, WBC and Plt number with bodymass and height Z-index. Conclusion. The study has demonstrated there is a correlation between RBC number, Hb concentration and height deviations in case of normochromicity. The relationship ascertained may be explained by an assumption that peculiarities of erythropoiezis correlate with body size. Lower RBC number and Hb concentration in children with smaller bodymass index may be due to general plastic deficiency in their organism. The results obtained in the present study may be used to reveal and analyze physical development and the organism morpho-functional peculiarities correlation markers.
