摘要

在对称的个体中,身体特征偏离双侧对称被认为是发育过程中环境扰动的结果。这种紊乱的一个原因可能是性类固醇,如睾酮和雌激素。该研究检查了第二和第四指比例(2D:4D)之间的关系,假定与产前睾丸激素负相关,与产前雌激素正相关,以及不对称。参与者的手被放在一个平面上,手掌朝上,前臂与中指在一条线上。测量二维:四维指长时,手指应最大限度地伸出并相互接触,测量方法可定义为指长近端屈曲折痕之间的距离,测量单位为厘米。表1给出了2D和4D左右距离的描述性分析。最低年龄和最高年龄分别为18岁和35岁。2D:4D右长均值为0.98±0.015,2D:4D左长均值为0.97±0.022,显示右侧2D:4D长度均值较高。我们的数据表明,低2D:4D(高产前睾丸激素的标志)和高2D:4D(高产前雌激素的标志)与不对称水平升高有关,这种关系尤其适用于手指不对称。关键词:2D:4D比例,面部不对称,眼-口-眼角度,学生

The Study of 2D:4D Ratio and Facial Asymmetry Using Eye-Mouth-Eye Angle among the Student of College of Medicine and Health Sciences, Federal University Dutse
Deviations of physical characteristics from bilateral symmetry, in otherwise symmetric individuals, are supposed to result from environmental perturbations during development. One cause of such perturbations may be sex steroids such as testosterone and oestrogen. The study examined the relationship between second to fourth digit ratio (2D:4D), a putative negative correlate with prenatal testosterone and a positive correlate with prenatal estrogen, and asymmetry. The hand of the participants was place on a flat surface with the palm facing upward fore arm in line with the middle finger. Finger should be extended maximally and dose to each other measurement technique was followed for measuring 2D:4D digit length which can be define as a distance between the proximal flexion crease of the digit length was measured in centimeters. Table 1 shows descriptive analysis of 2D and 4D right and left distance. The minimum and maximum ages are 18 and 35 years respectively. The mean of 2D:4D right length was 0.98 ± 0.015 and the mean of 2D:4D left length 0.97 ± 0.022 this shows there is higher mean value in right 2D:4D length. Our data show that both low 2D:4D (a marker of high prenatal testosterone) and high 2D:4D (a marker of high prenatal estrogen) are associated with elevated levels of asymmetry and this relationship applies particularly to finger asymmetry. Keywords: 2D:4D ratio, facial asymmetry, eye-mouth-eye angle, students
