Research on Body Mass Index of Students of Different Grades in Wenzhou University

The BMI(Body Mass Index) distribution and its characteristics in different grades were studied through analysis of the BMI of Wenzhou University students.Results showed that BMI of students in general is in good condition.The normal weight rates of male and female students are almost equivalent(both 79.8% in average).The low weight proportion of female students is greater than that of male students.The overweight and obesity proportions of male students are higher than that of female.The proportions of low weight and overweight remain relatively stable in different grades.Although obesity rate is not high,it still slightly increases with grade.Abnormal changes in BMI are easily appeared among the third and fourth grade students.The proportion of low weight male students is decreased,and proportion of overweight or obesity male students is increased.On the contrary,the proportion of low weight female students is greater than that of overweight or obesity female students.This paper suggests that the fitness health education of students should be strengthened in the higher educational institutions’ physical education,the warning mechanisms for fitness health of students should be set up.Special means and methods should be taken to control the phenomenon of adverse changes in students’ body weight.
