- Аннотация: Introduction. The previous studies of intersystem correlations inside constitutional integrity showed positive associations between the level of anxiety and EEG power for males and tendencies to lower transversal body dimensions of highly anxious persons regardless of sex. The goal of the present study is analysis of the morphophysiological basis of anxiety by Spielberger enlisting vaster database. Methods. The sample consisted of 105 students, aged 18-20 years (36 males, 69 females). The program embraced standard anthropometry to describe body build; EEG registration (eyes closed, monopolar, 12 cortical leads); Spielberger state and trait anxiety questionnaire (STAI). The coefficient of EEG asymmetry was calculated as ((L-R)/(L+R))×100 for theta-, alpha- and beta-bands. Mann-Whitney U-test and Spearman correlation coefficient were used for statistical analysis. Results. Females showed negative associations between the anxiety level and EEG asymmetry in alpha- and beta-bands: the higher EEG power in the right hemisphere as compared to the left one - the higher the anxiety level. For males there were no significant correlations between the anxiety level and asymmetry coefficients. Thus operating with asymmetry coefficient allowed to throw light on the character of correlations of EEG and anxiety for females. While for males the study confirmed the existence of positive associations of anxiety level and EEG power – mainly for the frontal and temporal cortical leads for high frequency alpha- and for frontal, temporal and occipital leads for beta-rhythm.The previously established larger leptosomy of highly anxious individuals remained at trend level. Spearman correlations analysis between EEG power and anthropometry (among EEG frequencies with maximal number of correlations with anxiety level) revealed for males significant associations of EEG power with height and leg length (for the frontal, central and parietal cortical leads). Besides, rare positive correlations were fixed for the forearm condyle width, biacromial diameter and sagittal chest diameter (mostly for central and parietal, partly – for temporal cortical leads). Direct correlation analysis between soma (anthropometric parameters) and anxiety level failed to obtain significant results. Still such parameters as higher height and higher leg length (i.e., dolichomorphy), as well as the tendency to macrosomy, can be considered as indicators of higher anxiety for males. The similar analysis for females didn’t reveal significant correlations between anthropometry and EEG-asymmetry.Conclusion. The results suggest that the higher level of anxiety for females is associated with negative coefficient asymmetry of EEG, while for males — with higher EEG power and dolychomorphy of body proportions.
