Morphological traits in the head and face of Kazakh adults in Yili, Xinjiang / 中国组织工程研究

ABSTRACT

BACKGROUND: The Kazakhs mainly live in the Yili Kazakh Autonomous Prefecture in northwestern Xinjiang. About 80% of the Kazakhs live in the areas of Yili, Tacheng, and Altay. To fully understand the physical characteristics of Kazakhs, a viviperception and head and face measurements of Kazakhs at the age of 20 and 86 were performed in Gilgelang Township, Gongliu County, Xinjiang. OBJECTIVE: To grasp the morphological traits in the head and face of Kazakh adults in Xinjiang. METHODS: Thirty-one head-face indexes of 422 Kazakh adults (219 males and 203 females) from Jiergelang county, Xinjiang were investigated. Twelve physical indices of the head and face were calculated. RESULTS AND CONCLUSION: In the Kazakh group, the incidence of eye fold of the upper eyelid was 92.7%; the rate of mongoloid fold was 9.9%; the appearance rates of flat and vertical types was 6.6% and 93.4%, respectively; the appearance rates of convex, concave and straight nasal profiles were 7.8%, 36.5% and 55.7%, respectively; the appearance rates of oblique, vertical and horizontal nostril shapes were 69.5%, 20.8% and 9.7%, respectively; the appearance rates of the chin of straight type and convex type were 68.2% and 31.8%, respectively; the appearance rates of earlobe type and non-earlobe type were 96.7% and 3.3%, respectively; the appearance rates of forehead hairline and non-forehead hairline were 72% and 28%, respectively; the appearance rates of straight hair and curly hair were 99.1% and 0.9%, respectively. Most of Kazakh males have dolichocephaly and hyperdolichocephaly (81.7%, 52.5%), hypsicephaly (93.6%), aerocephaly (84%), hyrerleptorrhiny (98.2%), and hypercuryen (74%). Kazak females most have dolichocephaly and hyperdolichocephaly (76.4%, 55.7%), hypsicephaly (97%), aerocephaly (84%), hyrerleptorrhiny (98.2%), and hypercuryen (74%). The head-face characteristics of Kazak population belongs to the North Asian type of Mongoloid．.
