Abstract: BACKGROUND: Digit ratio is basically 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 enrolled, 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 statistically 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, especially in 3D:5D(P < 0.05), and had bilateral differences, especially in 2D:4D and 4D:5D(P < 0.05). These findings indicate that the digit ratio of Xinjiang Kazakh people exhibits a bilateral difference, especially in 2D:4D and 4D:5D, as well as a sexual difference, especially in 3D:5D.
