Abstract

Introduction. The article is devoted to the study of associations of the 2D/4D ratio with other morphological features and with psychological indicators in a sample of mature and elderly women of Belgorod. The analysis of such associations may be related to an approach to the complex problem of the relationship between prenatal and late levels of sex hormones. Older ages have low representation in such studies, so the sample studied by the authors allows to a certain extent to fill in the gap. Materials and methods. The study was based on a sample of 50 women of mature and elderly age of the city of Belgorod. In the work we used the data of anthropometry, as well as the results obtained using the A. Muddy test of hardiness in the adaptation of D.A. Leontiev and the self-esteem scale of T. Dembo and S.Ya. Rubinstein. The subjective age of the study participants was also evaluated. Statistical methods included correlation and factor analysis performed in the Statistica 10 software package. Results. The 2D/4D ratio shows positive associations with fat deposition and body length. The study of the associations of the 2D/4D ratio with indicators of psychological hardiness and self-esteem shows statistically significant positive correlations and a high level of unidirectional variability of these signs. Both the indicators of hardiness and self-esteem are higher in women with more feminine values of the 2D/4D ratio. A lower subjective age is associated with more masculine 2D/4D ratio values. Conclusion. The results of the study can be considered as an indirect confirmation of the correspondence between prenatal and late hormonal ratios in women and the influence of early hormonal background on the formation of psychological characteristics in older age.
