摘要
最近，2D:4D比例的主题受到了极大的关注，因为有报道将其与睾酮和雌激素影响的特征联系在一起。本文报道了尼日利亚人2D、4D和2D:4D的研究及其与某些人体特征的关系。1400名受试者(男性713人，女性687人)参与了研究。男性的2D和4D长度显著高于女性(P <0.001)，而男性的2D:4D平均值低于女性(男性= 0.95±0.04，女性= 0.96±0.05,t = -1.73, P <0.001)。2D、4D与身高、体重、胸围、腰围、臀围呈显著相关。这项研究有力地证实了2D:4D的两性二态性。尽管它没有像其他研究那样显示2D:4D与BMI、胸围、腰围和臀围之间的关系。这可能是由于尼日利亚人口的多民族多样性造成的。
Sexual Dimorphism and Relationship between Chest, Hip and Waist Circumference with 2D, 4D and 2D:4D in Nigerians
Rescently the subject of 2D:4D ratio has received great attention because reports have linked to traits that are influenced by testosterone and estrogen. The present paper reports the study of 2D, 4D and 2D:4D and their relationship to some anthropometric traits in Nigerians. 1400 subjects (males = 713 and females n = 687) participated in the study. Lengths of 2D and 4D were significantly higher in males (P <0.001) while 2D:4D mean was lower in males than females (males = 0.95 ± 0.04 females = 0.96 ± 0.05, t = -1.73 and P < 0.001). 2D and 4D showed significant relationship with height, weight, chest, waist and hip circumferences. This study strongly confirms the sexually dimorphic nature of 2D:4D. Even though it fails to show relationship between 2D:4D and BMI, chest, waist and hip circumferences as reported in other studies. This could result from the multiethnic diversity of the Nigerian population.
