本文分析了山东省1985年儿童青少年体质健康调研资料,城市7～17岁6,600名学生(男女各半)的利比(Livi)指数((体重/身高)~(1/3)×1000)。各年龄组均值颇为接近(男生22.34-22.93,女生22.22-23.19)。从各年龄组随机抽取20名共440名学生,计算利比指数的95百分位数,男生为24.13,女生为24.17。为便于实用,男女都取利比指数24作为肥胖的界值;以体重超过身高标准体重的54%,利比指数26作为极度肥胖的界值。
This article analyzes the 1985 Physical and Health Survey of Children and Adolescents in Shandong Province. The Livi index ((body weight / height) ~ (1/3) × 1000) of 6,600 students aged 7-17 years (half male and half female) The average of all age groups is quite close (boys 22.34-22.93, girls 22.22-23.19). A total of 440 students were randomly selected from 20 age groups to calculate the 95th percentile of the Librex index, with 24.13 for boys and 24.17 for girls. To be practical, both men and women take the Liby Index of 24 as the cutoff for obesity; with a body weight exceeding 54% of the standard height weight and a Libya index of 26 as the threshold for obesity.
