Data regarding 2D:4D and other digit ratios in Greek population

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.

第二至四指比例（2D:4D）是一种性二态生物标志物，受孕前雌激素水平影响，并反映个体激素状况。过去，环境雌激素的暴露十分普遍。其内分泌干扰作用，结合其较长的半衰期，可能产生女性化效应并对健康产生影响。通过随机程序选取了160名希腊人作为分层样本，并使用电子卡尺测量了手指长度。初步统计分析显示，出生于1947年至1972年期间的中年人（即37岁及以下、38至63岁以及64岁及以上三个年龄段）与其它人群存在显著差异，因此原始样本随后被划分为三个年龄段子组。在38至63岁的希腊人中，2D:4D比例显著升高，尽管性二态性未受影响。其他手指比例也呈现相同的模式，即38岁以下的人群与63岁以上的人群共享相似的比例。原始数据伴随出版物《环境雌激素暴露与希腊人群的第二至四指比例：一种可能的联系》（DOI: https://doi.org/10.1016/j.earlhumdev.2020.105245）一同发布。该研究结合了以下数据集：[1] 《希腊男性和女性的手指比例与心肌梗死的关系》（DOI: https://doi.org/10.1016/j.genm.2010.11.008），[2] 《希腊人群中性二态的第二至四指比例（2D:4D）及其他手指比例的流行病学研究》（PMID: 19149213），[3] 《希腊老年人的2D:4D比例更高。这可能归因于环境影响吗？》（DOI: https://doi.org/10.1002/pds.1631），[4] 《希腊年轻人群腰臀比与身体质量指数的关系》（DOI: https://doi.org/10.1111/j.1742-7843.2009.00437.x）。
