目的建立合理适用的蒙古族7～18岁儿童青少年体质量参考值。方法对象来自“全国学生体质健康调研”蒙古族通辽校点2000年和2005年的调查数据。2000年获得有效人数5 563人,以年龄别体质量为指标采用有序样品聚类分析方法对样本划分最优年龄段,结合离差法建立各年龄段体质量的参考值范围;2005年获得有效人数2 990人,用以验证参考值范围正常率。结果城男分为7～8岁、9～11岁、12～13岁、14～15岁、16～18岁等5个最佳年龄段;乡男分为7～9岁、10～12岁、13～14岁、15～16岁、17～18岁等5个最佳年龄段;城女及乡女划分为7～8岁,9～10岁,11岁,12～13岁,14～15岁,16～18岁等6个最佳年龄段,建立了蒙古族儿童青少年的体质量参考值标准,共计32个参考值。结论本研究所建立的针对蒙古族儿童青少年体质量参考值标准,突出了简单实用的特点,同时填补了蒙古族儿童青少年年龄别体质量标准的缺乏,对预防蒙古族儿童青少年的营养不良、超重和肥胖有一定的指导意义。
Objective To establish a reasonable body mass reference value for Mongolian children and adolescents aged 7-18 years. Methods The subjects were from the survey data of “National Student Physical Health Survey” in 2000 and 2005 in Tongliao, Mongolia. In 2000, a total of 5 563 valid participants were obtained. The age-specific body mass index was used to divide the sample into the optimal age groups by using the method of orderly sample clustering analysis. The range of reference values for body mass of all ages was established by using the dispersion method. The effective number of 2,990 people, to verify the normal range of reference value. Results The urban boys were divided into 5 best age groups of 7 to 8 years old, 9 to 11 years old, 12 to 13 years old, 14 to 15 years old and 16 to 18 years old. The township men were divided into 7 to 9 years old and 10 to 12 years old , 13 ~ 14 years old, 15 ~ 16 years old, 17 ~ 18 years old and other 5 best age groups; urban and rural women are divided into 7 to 8 years old, 9 to 10 years old, 11 years old, 12 to 13 years old, 15 years old, 16 to 18 years of age, the best six age groups, the establishment of the Mongolian children and adolescents body mass reference standard, a total of 32 reference values. Conclusion The reference standards for body mass of children and adolescents established in this study highlight the simple and practical features while at the same time filling in the lack of age-specific body mass standards for Mongolian children and adolescents, and to prevent malnutrition among Mongolian children and adolescents, overweight And obesity have some guiding significance.
