【摘要】： 目的:国外学者研究表明指长比有性别、种族和地域差异,与个体攻击性行为、体育和音乐才能、艾滋病病毒易感性、心肌梗塞、乳腺癌、精子数量、精神分裂及同性恋等有关,但国内研究较少,故本文采用直接测量的方法,对大连地区汉族成人群体手指长及指长比进行调查分析,以明确大连地区指长比均值的分布特点,为国内开展此项研究积累资料。对象和方法:知情同意原则下,在2008年9月至2009年4月期间,随机抽取就诊于大连市第二人民医院的大连市内430(男220,女210)名健康汉族成人,采用人体测量学方法测量了其左右手第2-5指长度(掌侧),并计算各手指间的指长比值,并作性别差异和地区差异比较。结果: 1.指长:大连汉族群体第2-5手指长平均值左右侧男性分别为71.1、71.0,79.0、78.8,73.7、73.6,59.0、59.0;女性分别为66.9、67.0,73.8、73.8,68.5、68.7,54.7、54.8。大连汉族群体与鞍山汉族成人、辽宁汉族青年和新疆维吾尔族青年男女性各指长均有差异。 2.指长比:大连汉族群体2D:3D、2D:4D、2D:5D、3D:4D、3D:5D、4D:5D值左右侧男性分别为0.8995、0.9011,0.9650、0.9659,1.2074、1.2063,1.0731、1.0722,1.3431、1.3394,1.2522、1.2499;女性分别为0.9065、0.9079,0.9766、0.9753,1.2230、1.2226,1.0781、1.0754,1.3527、1.3502,1.2551、1.2558。男女性均表现为3D:5D4D:5D2D:5D3D:4D 2D:4D2D:3D。 3.左右差:同性别各手指长及各指长比左右侧间均无显著性差异(P0.05)。 4.性差:左右手各指长男女性间均有显著性差异(P0.05);左右手指长比均值女性高于男性,并且2D:3D、2D:4D和2D:5D有显著性差异(P0.05)。 5.2D:4D的百分比分布:男女性的左右手都以2D4D占主导,2D4D次之,2D=4D最少。但2D4D的百分比女性明显大于男性。 6.2D:4D地区差:大连汉族群体男女性均表现为低指长比,明显低于英袼兰、英国利物浦、匈牙利、波兰和西班牙,高于其他国家及地区或民族。结论:大连汉族群体指长和指长比有其独特性,并且在性别间存在差异。2D:4D具有明显的性别差异和地区差异。
[Abstract]:Objective: foreign scholars have shown that the ratio of length to sex, race and geographical differences, with individual aggressive behavior, sports and musical talent, HIV susceptibility, myocardial infarction, breast cancer, sperm count,Schizophrenia and homosexuality are related, but there are few studies in China, so this paper uses the method of direct measurement to investigate and analyze the finger length and finger length ratio of the adult population of the Han nationality in Dalian area, in order to clarify the distribution characteristics of the average finger length ratio in Dalian area.To accumulate data for domestic research.Participants and methods: during the period from September 2008 to April 2009, 430 healthy Han Chinese adults (220 males and 210 females) were randomly selected from Dalian second people's Hospital, Dalian City, under the principle of informed consent.The length of 2-5 fingers of the left and right hand was measured by anthropometric method, and the ratio of finger length between the fingers was calculated, and the sex and regional differences were compared.Results:1.Finger length: the average length of fingers in the Han population of Dalian was 71.1 / 71.0 / 71.0 / 79.0 / 73.73.7/ 73.6/ 59.0in Dalian Han nationality, respectively, and 66.9/ 73.8/ 73.8/ 73.8/ 68.74.7/ 54.8in women respectively.There were differences between Dalian Han nationality and Anshan Han adults, Liaoning Han youth and Xinjiang Uygur youth.2.Both sexes were 3D:5D4D:5D2D:5D3D:4D 2D: 4D2D: 3D.3.The difference between left and right: there was no significant difference of finger length and finger length between left and right of the same sex (P 0.05).4.Sex difference: there was significant difference between male and female in the length of left and right fingers (P 0.05), and the average length ratio of left and right fingers in female was higher than that in male, and there was significant difference between 2D: 3D: 2D: 4D and 2D:5D (P 0.05).The percentage distribution of 5.2D:4D: 2D4D was the dominant 2D 4D in male and female, and 2D 4D was the least in male and female.But the percentage of 2D4D in women was significantly higher than in men.The difference of 6.2D:4D area: the male and female of Dalian Han nationality showed low index and long ratio, which was obviously lower than that of England, England, Liverpool, Hungary, Poland and Spain, and higher than that of other countries or nationalities.Conclusion: the index length and finger length ratio of Dalian Han population have their own characteristics, and there are obvious gender differences and regional differences between sexes.
