Katedra Antropologii przy współpracy z naukowcami z Pracowni Biobank Uniwersytetu Łódzkiego oraz Uniwersytetu de Adelaide z Australii przygotowała artykuł dotyczący oceny zależności stosunku 2D:4D (stosunek długości drugiego palca do czwartego), a składem ciała na wybranym etapie postępowania ontogenezy – u polskich dzieci w wieku od 6 do 13 lat: Association of the 2D:4D digit ratio with body composition among the Polish children aged 6–13 years. Artykuł jest dostępny na łamach Early Human Development (35 pkt. MNiSW; IF = 2,025). Zapraszamy do lektury.

Aim

The aim of the study was to evaluate the relationship between the 2D:4D digit ratio and body composition during the chosen step of progressive ontogenesis- among children aged 6 to 13 years. There is few studies which tackle the problem of the fat and muscle mass in relation to the digit ratio (2D:4D) [3,29], thus conducted study seems to be an important contribution to knowledge about the digit ratio (2D:4D)

Conclusions

The 2D:4D digit ratio (in the right hand) in the analysed group of children at the age 6–13 years is significantly differentiated depending on sex; boys are characterised by lower values of the indicator.

The muscle mass variability of girls is also dependent on the proportion of sex hormones in prenatal life, which is visible as the value of the 2D:4D digit ratio.

We have found no relationship between the 2D:4D digit ratio values and the relative body weight and the WHR in both sexes what is inconsistent result with some previous studies.

Maternal traits, such as maternal education and maternal weight gain during pregnancy, significantly modify the body composition in the group of girls aged 6–13 years.
