Research On The Relationship Between Life Style And Healthy Physical Fitness Of Middle School Students In Shanghai

Objective:To investigate the basic situation of Shanghai middle school students’lifestyle and healthy physical fitness,and to explore the relationship between Shanghai middle school students’ lifestyle and healthy physical fitness.Methods:This study designed a questionnaire on health behavior and physical fitness.The content of the questionnaire was composed of demographic information,self-rating health and fitness scale,and lifestyle(physical activity,static behavior,sleep quality,diet)items.,select students from four middle schools in Shanghai for distribution.The questionnaire data were statistically analyzed using Mann-Whitney U test and chi-square test,Spearman correlation analysis,linear regression,and multivariate logistic regression analysis.result:A total of 1,500 questionnaires were distributed in this study,1,307 were recovered,and 1,038 were valid questionnaires,including 533 males and 505 females.(1)There are different demographic characteristics of middle school students’ lifestyle and physical fitness.Except for flexibility and fitness,boys have higher fitness levels than girls,and high school students have lower health and fitness levels than junior high school students.Boys are more physically active and eat carbonated fast food than girls,and girls have more static behaviors,fruits and vegetables than boys.Middle school students’ static behavior and carbonated fast food diet also showed significant differences in terms of residence and parents’ educational level.(2)In the correlation analysis,the correlation degree between middle school students’lifestyle and healthy physical fitness is physical activity,sleep quality,fruits and vegetables.Regression analysis showed that physical activity,fruits and vegetables,and sleep quality were significantly positive predictors of healthy physical fitness(p<0.05),while static behavior and carbonated fast food were significantly negative predictors(p<0.05).Physical activity was a good predictor of risk bias for healthy fitness,followed by sleep quality(both p<0.05 and higher OR).Generally speaking,the better the lifestyle of middle school students,the higher the level of health and fitness.Conclusions:The problem of insufficient physical activity among high school students in Shanghai is prominent.Girls spend more time static on weekends,boys consume more carbonated fast food,and high school students have poor sleep quality.The health and fitness level of high school students is lower than that of junior high school students.Middle school students’ physical activity,sleep quality,fruits and vegetables are most closely related to healthy physical fitness,and physical activity can highly predict the risk bias of healthy physical fitness.Schools,parents,and society should actively pay attention to the health-related lifestyles of middle school students,and help build middle school students’ living habits that focus on high physical activity levels,supplemented by good sleep quality and healthy diet.
