蒙古族与汉族7～18岁青少年维尔维克指数二十年变化趋势分析

Trend of Weierweike indexes in 7-18 years old Mongolian and Han adolescents during 20 years

目的以1995—2014年《中国学生体质与健康调研报告》中的蒙古族与汉族青少年维尔维克指数中数据为研究对象,对蒙古族与汉族青少年维尔维克指数的变化趋势进行分析,探索20年来蒙古族与汉族青少年维尔维克指数的差异。方法对比法,数据统计处理采用SPSS 20.0软件,维尔维克指数均数比较采用t检验。结果在20年的维尔维克指数变化趋势来看,蒙古族城市男维尔维克指数从低于汉族平均水平到基本一致。蒙古族城市女维尔维克指数在15～17岁普遍大于汉族。乡村男维尔维克指数在7～10岁普遍大于汉族。乡村女维尔维克指数在7～18岁普遍大于汉族。20年间蒙古族维尔维克指数青少年男性在7～10岁和18岁普遍大于女性,但是青少年女性维尔维克指数在13～16岁普遍大于男性。然而在2011—2014年,13～16岁女性与男性维尔维克指数基本相等。汉族维尔维克指数青少年男性在7～18岁普遍大于女性。蒙古族维尔维克指数青少年男性与汉族基本一致,而蒙古族青少年女性维尔维克指数普遍大于汉族。结论我国7～18岁青少年维尔维克指数蒙古族整体水平高于汉族,蒙古族青少年男性普遍高于女性,汉族青少年男性普遍高于女性。

Objective To investigate the trend of Weierweike indexes in 7-18 years old Mongolian and Han adolescents during 20 years and explore the difference between Mongolian and Han adolescents in the Weierweike indexes. Methods The Weierweike index data were collected from the 'Research report on physical fitness and health of Chinese students from 1995 to 2014' and the data were statistically analyzed by SPSS 20.0 software. Results During the 20 years, the trend of Weierweike index of the Mongolian city male adolescents was from below the Han average level to basically the same. The Weierweike index of the Mongolian city female adolescents was generally higher than that of the Han adolescents at the age of 15-17 years. The Weierweike index of the Mongolian country male adolescentswas generally higher than that of the Han adolescents at the age of 7-10 years. The Weierweike index of the Mongolian country female adolescents was generally higher than that of the Han adolescents at the age of 7-18 years. During the 20 years, the W eierweike index of Mongolian male adolescents was generally higher than that of the females at the age of 7-10 years and 18 years, but the Weierweike index of the female adolescents was generally higher than that of the males at the age of 13-16 years. However between 2011 and 2014, the Weierweike indexes of the female and male adolescents were basically the same at the age of 13-16 years. The Weierweike index of Han male adolescents was generally higher than that of the females at the age of 7-18 years. The Weierweike indexes of the Mongolian and Han male adolescents were basically the same, while the Weierweike index of the Mongolian female adolescents was generally higher than that of the Han adolescents. Conclusion In our country, the overall level of the Weierweike index of the Mongolian adolescents is higher than that of the Han adolescents at the age of 7-18 years. In addition, the level of the Weierweike index of the male adolescents is generally higher than that of the female adolescents both in Mongolian and Han.
