Abstract:
Objective To describe the prevalence and relationship between screen time and sub -health status among middle school students in weekdays and weekends .Methods With multistage stratified random cluster sampling , 14 400 students from junior and senior middle schools in 288 classes of 30 schools in 4 cities ( Shenyang , Chongqing , Xinxiang , Guangzhou ) were investigated in October , 2011.A total of 13 817 valid questionnaires were retained for analysis.Survey content includes general demographic information, screen time,sub-health state.Logistic regression model was used to analyze the relationship between screen time and sub-health status .Results The screen time among middle school students >2 h/d on weekdays and weekends were 15.1%(2 085/13 817) and 58.5%(8 077/13 817), respectively.Among them, the boys′screen time >2 h/d on weekdays and weekends were 17.9%(1 187/6 644) and 61.3%(4 070/6 644), which were higher than girls (12.5% (898/7 173), 55.9%(4 007/7 173)) (χ2 values were 76.95 and 41.35, respectively.P<0.01).The prevalence of physical sub-health status, psychological sub-health status and sub-health status were 24.8%(3 431/13 817),21.7%(2 997/13 817) and 22.1%(3 051/13 817), respectively.Among them, the girls′prevalence of physical sub-health status, psychological sub-health status and sub-health status were 26.0%( 1 863/7 173 ) , 22.9%( 1642/7 173 ) and 23.1%(1 658/7 173)), respectively,which were higher than boys′(23.6%(1 568/6 644),20.4%(1 355/6 644) and 21.0%(1 393/6 644)) (χ2 values were 10.39,12.66 and 9.25,respectively .P<0.05).The senior students′prevalence of physical sub-health status, psychological sub-health status and sub-health status were 31.6%( 2 176/6 884 ) , 28.3%( 1 946/6 884 ) and 28.9%( 1 990/6 884 ) , respectively,which were higher than junior students′(18.1%(1 255/6 933),15.2%(1 051/6 933) and 15.3%(1 061/6 933)) (χ2values were 337.65,349.46 and 371.54, respectively, P <0.05).After adjusting on demographic characteristics , compared with screen time ≤ 2 h/d on weekday , screen time>2 h/d on weekday was significantly associated with physical sub-health status, psychological sub-health status and sub-health status ( OR ( 95%CI ): 1.39 ( 1.25-1.55 ) , 1.62 ( 1.45-1.81 ) and 1.59 ( 1.43-1.78)).And compared with screen time ≤2 h/d on weekend,screen time >2 h/d on weekend was also significantly associated with physical sub-health status , psychological sub-health status and sub-health status (OR(95%CI):1.49(1.37-1.61),1.81(1.66-1.98), and 1.71(1.57-1.87)).Conclusion The rate of the screen time >2 h/d and the detection ratio of sub-health among the middle school students in Shenyang , Chongqing , Xinxiang , Guangzhou in 2011 were high.Screen time >2 h/d on weekdays or weekends was a risk factor for sub-health status.
