Associations of physical activity and screen time with emotional and behavioral disorders among 10-year-old children in rural areas
Objective To examine the effects of physical activity and screen time on emotional and behavioral disorders among children in rural areas.Methods Children at an age of 10 years and their parents were surveyed based on a small birth cohort.Chil-dren's emotional and behavioral disorders were assessed using the parental version of the strength and difficulties questionnaire(SDQ),and the physical activity and screen time were evaluated using the WHO Self-rated Health Behavior in School-Aged Survey Questionnaire.The associations of physical activity and screen time with emotional and behavioral disorders were examined among rural children.Results A total of 450 children were enrolled in the cohort.The proportions of inadequate weekday and weekend physical ac-tivity were 63.1％and 51.8％,and the proportions of screen time exceeding the standard were 6.9％and 28.0％.The highest propor-tion of abnormal emotions and behaviors was peer interaction(28.9％),followed by hyperactivity/attention deficit(15.6％),emotional symptoms(8.7％),prosocial behaviors(7.6％)and conduct disorder(6.9％),and the prevalence of hyperactivity/attention deficit(18.8％vs.11.9％,P＜0.05)and prosocial behaviors(10.8％vs.3.8％,P＜0.05)was higher among men than among women.Multi-variate analysis showed that children with inadequate weekday physical activity were more likely to develop peer interaction[odds ratio(OR)=1.61％,95％confidential interval(CI):(1.01,2.58)],and children with weekend screen time exceeding the standard were more likely to develop hyperactivity/attention deficit[OR=2.42,95％CI:(1.38,4.25)]and prosocial behaviors[OR=3.03,95％CI:(1.41,6.47)].Conclusions Peer interaction and hyperactivity/attention deficit are main emotional and behavioral disorders a-mong rural children,and weekday physical activity and weekend screen time may affecting the mental health among children.
