Abstract:

Objective To investigate the health-related sedentary behavior (SB) characteristics of adolescents aged twelve to 17.Methods From May to July, 2020, 300 adolescents were sampled and tested SB, break of sedentary time (BST), light physical activity (LPA) using wGT3X-BT accelerometer and Adolescent Sedentary Behavior Questionnaire.Results The objective measurement showed that the daily sedentary time was high (80.28% on weekdays and 81.38% on weekends). The proportion of sedentary time was high in girls than in boys both on weekdays and weekends (F > 5.322, P < 0.05). There were significant differences in the proportion of SB (weekdays/weekends), the frequency of BST (weekdays/weekends), and the proportion of LPA (weekdays/weekends) among different grades ( F > 11.355, P < 0.001). The subjective measurement showed that the sedentary time more than eight hours were 86.67% and 63.67% of children and adolescents on weekdays and weekends, respectively. The educational SB, social SB and video SB were the main types for children and adolescents. The educational SB time increased, and the social SB and video SB time decreased with grades. Traffic SB and cultural SB accounted for a small proportion of the total sedentary time. There were significant differences in social SB (weekdays), cultural SB (weekends), video SB (weekdays/weekends), educational SB (weekdays/weekends) and traffic SB (weekdays/weekends) among different grades ( F > 2.934, P < 0.05). Conclusion The sedentary time is high among children and adolescents, in which educational SB accounts the most, and varies with grade.
