Abstract:
Objective:To investigate the associations of moderate to vigorous intensity physical activity (MVPA) and screen time (ST) with emotional and behavioral problems in children and to provide evidence for related intervention measures.
Methods:In March 2017, a total of 4 922 children aged 6-12 years from 5 primary schools in Guangzhou were enrolled using stratified random cluster sampling method. Questionnaires were used to assess children s socio demographic information, MVPA, ST and emotional and behavioral problems. The associations of MVPA and ST with behavioral problems were explored by using generalized linear mixed models.
Results:Students with MVPA≥60 min per day accounted for 37.5%, and with ST≤2 h per day accounted for 87.7%. Children who were physically active showed lower scores for total difficulties, hyperactivity, and peer problems and higher score for prosocial than inactive peers( t =2.80, 2.47, 2.56, -1.97, all P <0.05). Also, children who spent less than 2 h ST per day reported lower scores for total difficulties, emotional symptoms, conduct problems, hyperactivity, and peer problems and higher score for prosocial compared to those with high ST( t =3.18, 3.35, 3.70, 3.80, -3.21, 4.97, all P <0.05). Children who met neither MVPA nor ST recommendations had significantly increased risks of total difficulties( OR=1.73, 95%CI =1.12-2.68), conduct problems( OR=1.45, 95%CI =1.02-2.05), peer problems( OR=1.93, 95%CI =1.11-3.36), and prosocial ( OR=1.55, 95%CI =1.08-2.23) than those who met both.
Conclusion:MVPA and ST are independently related to children s emotional and behavioral problems, and the risks of emotional and behavioral problems increased in children with insufficient MVPA and longer ST.
