河北汉族人群指纹与扣手方式的相关性分析

Analysis of correlation between fingerprint and posture of hand clasping of Han nationality people in Hebei

目的：探讨河北汉族人群指纹纹型分布与扣手方式之间是否具有关联性。方法：调查了300例青少年的扣手方式，并采用无油墨法获取研究对象的指纹。结果：十指交叉时，左扣手人群的各种纹型频率为L（52．13％）〉W（44．73％）〉A（（3．13％），右扣手人群的各种纹型频率为L（60．13％）〉W（35．67％）〉A（（4．2％），其中L^u、L和W型纹的分布频率两者间具有差异。A形纹多见于示指，其次是拇指。L^r多见于示指，其次是拇指。L^u多见于小指，其次是中指。W多见于环指，其次是拇指。拇指中出现L^u、L和W纹型的频率，中指出现A、W纹型的频率，环指出现L^r纹型的频率两人群间差异具有统计学意义。AL、LL。和LW的对应手指纹型组合频率两人群间存在差异。各指纹型组合中，拇指中AA和LL、示指AL、中指AL和LW、小指中LW组合频率两人群间差异具有统计学意义。结论：河北汉族左扣手人群和右扣手人群的指纹纹型分布具有一定的差异性。在一定程度上说明手指纹与扣手方式有一定的关联性。

Objective, To explore the correlation between distributions of fingerprint patterns of Han nationality people in Hebei and posture of hand clasping. Methods ： Posture of hand clasping data in 300 cases was explored. Fingerprint was obtained using non-inkless method. Results, The hands were crossed together, frequencies of different fingerprint patterns of left-hand clasping people were L （52. 13%）〉W （44. 73%）〉A（（3.13%）. Frequencies of different fingerprint patterns of right-hand clasping people were L（60. 13%）〉W（35.67%）〉A（（4. 2%）. Frequencies of L^u, L and W showed a significant difference between two groups. A was mainly distributed in the index fingers, and then in the thumb. L^r was mainly distributed in the index fingers, and then in the thumb. L^u was mainly distributed the in little fingers, and then in the middle. W was mainly distributed in the ring fingers, and then in the thumb fingers. L^u, L and W frequencies of the thumb, A and W frequencies of the middle finger, L^r frequencies of the ring finger showed a significant difference between two groups. Combination frequencies of corresponding fingers were significantly different in AL, LL and LW frequencies between two groups. Among combination of fingerprint patterns on different fingers, AA and LL frequencies of the thumb, AL frequencies of the index finger, AL and LW frequencies of the middle finger, LW frequencies of the little finger showed a significant difference between two groups. Conclusion. There are some differences between two groups of left-hand clasping and right-hand clasping of Han nationality in Hebei, suggesting that there be some correlations between fingerprint and posture of hand clasping.
