Abstract:
Objective:To analyze the relationship between outdoor activity, screen time and 20 meter shuttle run test (20 m SRT) score among children and adolescents in Baoan District, Shenzhen, so as to provide scientific basis for the management and promotion of physical health of children and adolescents.
Methods:Stratified cluster sampling was used to select students from 14 schools in 6 communities in Baoan District of Shenzhen, from April to May 2019. A self designed questionnaire was used to investigate demographic characteristics, outdoor activity duration and screen time of primary and middle school students. A total of 3 192 primary and secondary school students in grade 1-12 were selected from each school. Weight, height and 20 m SRT were measured.
Results:About 985(30.9%) out of 3 192 primary and middle school students were estimated excellent on 20 m SRT test, with boys being higher than that of girls (34.7% vs 26.3%) ( χ 2=26.43, P <0.01). Logistic regression analysis showed that compared with the group with outdoor activity <2 h/d, the excellent and good performers on 20 m SRT with outdoor activity time ≥2 h/d was higher( OR=1.38, 95%CI =1.12-1.70). Compared with students with screen time ≥2 h/d, the excellent and good performers on 20 m SRT with screen time <2 h/d was higher( OR=1.42, 95%CI=1.17-1.71). Compared with students with outdoor activity time < 2 h/d and screen time ≥ 2 h/d, students with outdoor activity time ≥2 h/d and video time < 2 h/d had a higher proportion of excellent score on 20 m SRT( OR=1.97, 95%CI =1.46-2.67).
Conclusion:Increasing outdoor activity and reducing screen time are helpful to improve the performance score of 20 m SRT among primary and secondary school students.
