Description

Second–to–fourth digit ratio (2D:4D) is a sexually dimorphic biometric marker, which is influenced by prenatal estrogen levels and reflects to the hormonal profile of each individual. Exposure to environmental estrogens was common in the past. Their endocrine–disrupting action, combined with their long half–time, may have a feminizing effect and an impact on health. A stratified sample of 160 Greek people was selected by random procedures and fingers’ length was measured by means of an electronic caliper. Based on preliminary statistical analysis, middle aged persons, corresponding to birth in the period 1947–1972, were found to differ significantly from the rest and the original sample was subsequently divided into three age subgroups (≤37, 38–63 and ≥ 64 years old). 2D:4D ratio was found significantly higher in Greek people aged from 38 to 63 years old, although sexual dimorphism remained unaffected. The other digit ratios followed the same pattern, with people aged less than 38 years to share equivalent ratios with people aged more than 63 years.
