背景：在人类胚胎期的前3个月指长比值就基本确定，指长及指长比具有性别和侧别差异，指长比可能还存在民族、地区及人种差异，至今尚未有人进行过新疆哈萨克族成人指长比方面的研究。 　　目的：探讨新疆哈萨克族青年人群指长比的特点。 　　方法：随机选择18-25岁健康新疆哈萨克族青年200例(男100例，女100例)，进行双手后前位X射线拍片，分别测量指骨长度，同时测量身高，将所得数据用SPSS 19.0软件进行统计学分析处理。 　　结果与结论：新疆哈萨克族青年人群指长均呈现3D>4D>2D>5D；男性指长比具有3D∶5D>4D∶5D>2D∶5D>3D∶4D>2D∶3D>2D∶4D趋势，女性指长比具有3D∶5D>2D∶5D>3D∶4D>4D∶5D>2D∶4D>2D∶3D趋势；左右手2D∶3D，3D∶4D，4D∶5D指长比均值男性大于女性，左右手2D∶4D，2D∶5D，3D∶5D指长比均数女性大于男性，男女性左右手指长比2D∶4D和4D∶5D的差异有显著性意义(P <0.05)；不同性别中，左侧指长比3D∶5D差异有显著性意义(P<0.05)。结果说明，新疆哈萨克族指长比具有侧别差异性，其中以2D∶4D和4D∶5D最为显著；性别差异性3D∶5D最为显著。

BACKGROUND:Digit ratio is basical y determined within the first 3 months of fetal development. Digit and digit ratio exhibit differences between genders and between left and right hands. Nationality, regional and ethnic difference may also influence the digit ratio. So far, there is no report about the digit ratio of Kazakh adults. OBJECTIVE:To study the characteristics of digit ratio of young Kazakh nationality in Xinjiang of China. METHODS:A total of 200 young Kazakh volunteers in Xinjiang, aged 18-25 years, were enrol ed, including 100 males and 100 females. These participants were subjected to posteroanterior X-ray of both hands. Phalanx length and body height were measured, and the resulting data were statistical y analyzed using SPSS19.0 software. RESULTS AND CONCLUSION:The digit ratio of Xinjiang Kazakh people was 3D>4D>2D>5D. Male digit ratio possessed the tendency of 3D:5D>4D:5D>2D:5D>3D:4D>3D:4D>2D:3D>2D:4D;female digit ratio possessed the tendency of 3D:5D>2D:5D>3D:4D>4D:5D>2D:4D>2D:3D. The digit ratio of 2D:3D, 3D:4D, 4D:5D was higher in the male than the female;the digit ratio of 2D:4D, 2D:5D, 3D:5D was higher in the female than the male. Digit ratio had sexual differences, especial y in 3D:5D (P<0.05), and had bilateral differences, especial y in 2D:4D and 4D:5D (P<0.05). These findings indicate that the digit ratio of Xinjiang Kazakh people exhibits a bilateral difference, especial y in 2D:4D and 4D:5D, as wel as a sexual difference, especial y in 3D:5D .
