不同BMI等级初中学生体质健康状况的比较研究
A COMPARATIVE STUDY OF PHYSICAL HEALTH STATUS AMONG JUNIOR MIDDLE SCHOOL STUDENTS WITH DIFFERENT BMI GRADES
摘要
Abstract
Objective To investigate the physical health status of junior middle school students with different body mass index (BMI) grades and to explore the influence of BMI on junior middle school students' physical health.Methods With reference to the "National Physical Health Standards for Students (revised in 2014)",a total of 4 662 second-year middle school students in Qingdao,China were selected to examine their body shape index (height and weight),physical function index (vital capacity),and physical quality index (50 m race,sit-and-reach,standing long jump,chimup (male)/one-minute sit-up (female),and 1 000 m race (male)/800 m race (female)).Based on BMI,these students were classified into four groups:standard weight group,low weight group,overweight group,and obesity group.The mean scores of all physical health indices and the total physical health score were compared between these groups.Results In both male and female students,the standard-weight group had significantly higher mean scores of all physical health indices than the other three groups (F=4.07-422.20,P＜0.05);the total physical health score was distributed in an inverse V shape with the increasing BMI,and the standard-weight group had a significantly higher total physical health score than the other three groups (F =308.42,477.18;P＜0.01),suggesting that extremely high or low BMI was not conducive to students' physical health.Conclusion BMI has considerable influence on students' physical health.Obesity,overweight,and underweight are the factors responsible for physical health decline in students.关键词
