Correlation between physical fitness and frequency of breakfast consumption of middle school students / 中国学校卫生

ABSTRACT

Objective@#To investigate the breakfast consumption of middle school students and to analyze its relationship with physical fitness, so as to provide reference for improving physical fitness of middle school students.@*Methods@#A total of 2 732 middle school students from Shangrao City were selected in September 2021 by random cluster stratified sampling. The breakfast consumption behaviors of middle school students were investigated by questionnaire, and the general information, family information and other lifestyle behaviors were collected. The physical fitness test includes grip strength, standing long jump, 1 minute sit up, sit forward bend, 50 m run and 20 m shuttle run test (20 m SRT) to evaluate the strength, flexibility, speed and endurance of middle school students. χ 2 tests were used to compare the correlation between different demographic characteristics, breakfast behavior and physical fitness,and Logistic regression analysis was used to infer the correlation strength between breakfast behavior and physical fitness.@*Results@#The detection rate of physical fitness failure among middle school students was 21.5%. There were statistically significant differences between breakfast frequency and grip strength and 20 m SRT( χ 2=8.27, 13.90, P < 0.05 ). Logistic regression analysis results showed that 20 m SRT was positively correlated with breakfast frequency (sometimes eat breakfast, OR =1.51, skip or occasionally eat breakfast OR =2.08, P <0.05).@*Conclusion@#The low frequency of breakfast consumption of middle school students is associated with low performance on 20 m SRT. Schools and families should pay attention to the breakfast consumption of middle school students to ensure adequate daily nutrition intake.
