Investigation On The Status Of Sleep And Obesity And Their Correlation Among Students In Shenyang

Objective:To understand the current status and relationship between sleep and obesity among primary and secondary school students and college students in Shenyang,and to explore the influencing factors affecting sleep duration,so as to provide reference for further research on the causes of childhood and adolescent obesity,improving sleep time,promoting health,and formulating relevant intervention measures.Methods:Students from 2 primary schools,2 middle schools and 2 universities in a district of Shenyang were selected by convenient sampling.The main contents of the questionnaire include the time when children and adolescents go to bed and get up every day,the quality of sleep,the time of watching TV,computers and mobile phones and other video,the sports and learning conditions,the way of going to school and other basic information.Overweight or obese was judged according to the body mass index classification standard developed by China working group on obesity.According to the "daily study time hygiene requirements for primary and secondary school students"(GB/ T17223-2012),determine whether students lack of sleep.SPSS22.0 was used for data entry and statistical analysis.Results:1.A total of 4229 children and adolescents were surveyed in this study,and their average sleep duration was 8.47 hours per day.The average sleep time of students aged 6-8,9-11,12-15 and 18-22 was 9.43 h,9.15 h,7.61 h and 7.73 h,respectively.The detection rate of insufficient sleep was 70.74%,84.16%,93.69% and 9.39%,respectively.2.The overweight and obesity detection rates of the respondents in this study were 16.58% and 15.89%,respectively.The overweight rate of students aged 6-8,9-11,12-15 and 18-22 was 16.45%,17.99%,22.29% and 10.96%,respectively.The detection rates of obesity were 23.21%,20.60%,16.40% and 5.35%,respectively.The detection rates of overweight and obesity in all age groups were higher in boys than in girls.3.There was a significant difference in the detection rate of overweight and obesity among primary and middle school students with different sleep duration,and there was a negative correlation between sleep duration and BMI of primary and middle school students.BMI increased with the decrease of sleep duration.There was no correlation between sleep duration and BMI in college students.4.The main factors affecting the sleep time of primary and secondary school students include video time,sports and schoolwork burden.Students' sleep time decreases with the increase of daily video time and increases with the increase of exercise frequency.Students in primary and middle schools,mainly by car,have less sleep time than students walking or cycling to school.Long video screen time is the main risk factor affecting the sleep time of college students,but the time of class and study after class have no significant influence on the sleep time of college students.Conclusion:The incidence of insufficient sleep in primary and middle school students aged 6-15 in Shenyang is high,averaging 82.90%.The detection rate of overweight and obesity was higher,with an average of 20.10%,and the sleep duration was negatively correlated with BMI of primary and middle school students.Video time,exercise time and study time are the main risk factors affecting the sleep time of primary and middle school students.The sleep status of college students is obviously different from that of primary and middle school students.The rate of insufficient sleep is very low,with an average of 9.40%.Daily video time >2h was the main risk factor affecting the sleep time of college students.There was no correlation between sleep duration and BMI in college students.
