Objective To understand the current situation of sit-and-sit behavior of children and adolescents in Beijing and its effect on health status, and provide a scientific basis for the formulation of health behavior intervention. Methods A questionnaire survey of 5,876 adolescents aged 11, 13 and 15 in Beijing’s 6 districts and counties was conducted using the Chinese version of the revised “School-aged Children’s Health Behavior” questionnaire. Results The total time of sit-in for children and adolescents at school days and weekends was 3.75 and 8.03 h, respectively, showing an upward trend with age. Homework was the main source of sitting activity on school days, accounting for 64.9%; watching television, using computers and games accounted for only 21.0%, 8.5% and 5.3%. The proportion of homework hours weekends dropped to 39.0%, the proportion of screen time increased. The proportion of children aged 11, 13, and 15 years old with viewing time> 2 hours on the school day was 37.9%, 29.3% and 19.8% respectively, while the weekend viewing time> 2 hours were 79.9%, 85.1% and 87.0% respectively. Conclusion The situation of children and adolescents in Beijing is not optimistic about their sit-in behavior, especially when their homework is too long. The education and health department should carry out the education of healthy behavior against the characteristics of teenagers’ sit-in behavior.
