Anthropologic study of 5 tongue movements of Han nationality in Jinzhou Liaoning

目的：探讨辽宁锦州地区汉族成年人卷舌、叠舌、翻舌、尖舌、三叶舌5项舌运动类型出现情况，为人类学群体遗传学积累资料。方法：在知情同意的基础上，随机调查了辽宁锦州地区汉族健康成年人381例（男185例，女196例）卷舌、叠舌、翻舌、尖舌、三叶舌5项舌运动类型。结果：5项舌运动类型的出现率分别为67．98％、43．57％、28．61％、83．73％、11．02％。除翻舌外，其他4项舌运动类型的出现率无性别间差异。与其他地区汉族族群及少数民族相比，辽宁锦州汉族三叶舌出现率较低，其他4种舌运动类型出现率均属于中等类型。卷舌分别与叠舌和三叶舌之间存在相关，翻舌与三叶舌之间存在相关，其他舌运动类型间无相关性。结论：辽宁锦州地区汉族舌运动类型出现率无性别差异，总体而言，舌运动能力较高。

Objective： To study 5 tongue movements including tongue roiling, tongue folding, tongue twisting, pomtea tongue and clover-leaf tongue of Han in Jinzhou Liaoning province to accumulate data for human anthropology. Methods： 381 samples （185 males, 196 females） of Han in Jinzhou Liaoning were investigated on 5 tongue movements. Results： （1） The frequencies of tongue rolling, tongue folding, tongue twisting, pointed tongue and clover-leaf tongue were 67. 98%, 43.57%, 28. 61%, 83.73% and 11.02% respectively. There were significant sexual differences in the frequencies of tongue twisting, while not of other tongue movements. （2） Compared with other nationalities, Han in Jinzhou had a lower frequen- cy of clover-leaf tongue, while other tongue movements were middle types. （3） Tongue rolling had interactive relations with tongue folding and clover-leaf tongue; and tongue twisting had interactive relations with clover-leaf tongue. There were no correlations in other tongue movements. Conclusion： There are no significant sexual differences in the frequencies of tongue move- ments of Han in Jinzhou Liaoning province. In general, there are higher potentials of totague movement in this area than other areas.
