Association of 24-hour movement behaviors with emotional and behavioral problems among left-behind children
Objective To examine the association of 24-hour movement behaviors with emotional and behavioral problems among left-behind children,so as to provide a theoretical reference for the practice of 24-hour activity interventions to promote emotional and behavioral problems in this population.Methods From February to May 2023,1 117 left-behind children in grades 4-6 from 10 primary schools in five cities in Zhejiang Province were selected using a convenient cluster sampling method to conduct a ques-tionnaire survey examining 24-hour movement behaviors,as well as emotional and behavioral problems.The general linear model was adopted to analyze the association between satisfying the 24-hour movement behavior guidelines,and emotional and behavioral problems among left-behind children.Results The sleep duration compliance rate was the highest(52.19％),while the moderate-to-vigorous PA(MVPA)compliance rate was the lowest(17.73％).The compliance rate of the three activities accounted for 7.43％.There was a dose-response between the number of guidelines satisfied,and the emotional and behavior of left-behind chil-dren;that was,satisfaction of a higher number of guidelines was associated with a lower risk of emotional and behavioral problems among left-behind children(difficulty factor:β=-0.56,95％CI=-1.23--0.19;strength factor:β=0.50,95％CI=-0.48-1.22,P＜0.01).Compared to satisfying none of the guidelines,satisfying the guidelines for screen time(β=-0.23,95％CI=-2.18--0.14)and sleep duration(β=-0.13,95％CI=-1.66--0.11)was negatively correlated with the difficulty factor,while satisfying the guideline for MVPA(β=0.13,95％CI=0.09-1.08)and sleep duration(β=0.18,95％CI=0.09-1.40)was positively associat-ed with the strength factor.In addition,satisfying two or all three of the guidelines was more strongly associated with these outcomes than satisfying one of the recommendations(P＜0.01).Conclusions Meeting the 24-hour movement behavior guidelines can im-prove emotional and behavioral problems among left-behind children.It is necessary to raise their awareness of the effect of satisfying the 24-hour movement behavior guidelines and formulate comprehensive intervention measures.
