The correlation between body mass and academic performance of elementary and middle school students ——Based on the data of elementary and middle school students in a certain city in Shanxi province

采用描述统计和计量回归模型,对陕西省某市2012年168所中小学共79 475名学生的身高体重等级和学业成绩研究发现:中国欠发达地区体重等级不良的学生规模较大,44.85%中小学生体重偏轻,16.44%体重偏重;体重偏轻与中小学生学业表现呈显著正相关;小学和初中阶段,体重偏重与学业表现无显著相关;在高中生子群体中,体重偏重与学业表现呈显著负相关,其中偏重的高中女生中学习成绩更差。

By using descriptive statistics as well as measurement and regression model, the authors studied the height and body weight ratings and academic performance of 79 475 students in 168 elementary and middle schools in a certain city in Shanxi in 2012, and revealed the following findings: in an underdeveloped region in China, the percentage of students with a poor body weight rating was big, 44.85% of the elementary and middle school stu-dents had a body weight on the light side, while 16.44% of them had a body weight on the heavy side; there was a significant positive correlation between body weight on the light side and the academic performance of the elemen-tary and middle school students; at elementary and junior middle school stages, there was no significant correlation between body weight on the heavy side and academic performance; in the subgroup of high school students, there was a significant negative correlation between body weight on the heavy side and academic performance, in which the high school girls with a body weight on the heavy side had poorer academic performance.
