摘　　要：目的研究宁夏回、汉族群体指长比,比较分析宁夏两种不同民族、不同性别群体左右手及不同民族指长比均值的分布特点。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)左右手指长比(2D:3D、2D:4D、2D:5D、3D:4D、3D:5D、4D:5D)。结果指长比均值呈现2D:3D<2D:4D<3D:4D<2D:5D<4D:5D<3D:5D的趋势;同一民族左右手指长比均数女性高于男性,且2D:3D、2D:4D、2D:5D有显著性差异(P<0.05);同一性别不同民族左右手指长比无显著性差异。结论指长比在性别间存在差异,2D:4D具有明显的性别差异。Objective To study the digit ratio of the Hui and the Han ethnic groups in Ningxia,analyze the mean values of left and right hands of different sexes and nationalities,and compare the characteristics of mean values distribution in different races. Methods Physique measurements were used to study the digit ratios（2D：3D;2D：4D;2D：5D;3D：4D;3D：5D;4D：5D）of left and right hands of 412 individuals（219 males,193 females） of the Hui and 439 individuals（241 males,198 females） of the Han nationalities. Results Mean values of digit ratios present a trend as： 2D：3D〈2D：4D〈3D：4D〈2D：5D〈4D：5D〈3D：5D.Significant differences of 2D：3D;2D：4D;2D：5D of left hands and right hands were found between males and females in the same nationality（P〈0.05）.Females had higher mean values than males.For the same sex,there was no significant difference in the mean values of left hands and right hands between different nationalities.Conclusion There is sexual difference in digit ratio and an abvious sexual difference in 2D：4D.The mean values of 2D：4D of the Hui and the Han in Ningxia are lower than those in European countries like Britain.
