目的探讨宁夏回、汉族群体指长波动性不对称(FA),比较分析宁夏两种不同民族、不同性别群体指长FA均值的分布特点。方法采用体质测量法,研究宁夏回族412例(男219例,女193例)、汉族439例(男241例,女198例)指长FA(2FA、3FA、4FA、5FA)及复合FA(CFA)的均值,并比较其均值的差异性。结果宁夏回、汉族群体指长FA均值均呈现2FA>4FA>3FA>5FA的趋势;同一民族不同性别各指长FA均值男性高于女性,有显著性差异;同一性别不同民族各指长FA均值无显著性差异;男性2FA在|L-R|≥0.04组显著高于女性(P<0.05)。结论指长FA,尤其是2FA存在性别差异。
Objective To explore the long-run asymmetry (FA) of the Hui and Han ethnic groups in Ningxia and to compare and analyze the distribution characteristics of the FA mean of the long and long fingers of two ethnic groups in different ethnic groups in Ningxia. Methods The body mass measurement method was used to study 412 Hui women (219 males and 193 females) in Ningxia Hui Autonomous Region. 439 Han patients (241 males and 198 females) were enrolled in this study. The FA (2FA, 3FA, 4FA and 5FA) ) Mean, and compare the average of the differences. Results In the Ningxia Hui and Han ethnic groups, the means of long FA showed the trend of 2FA> 4FA> 3FA> 5FA. The mean of FA of different fingers of the same ethnicity was higher than that of female, with significant difference. The mean of FA of different nationalities of the same sex There was no significant difference between the two groups; the male 2FA was significantly higher than the female in LR | ≥0.04 group (P <0.05). Conclusion The long-FA, especially 2FA, has sex differences.
