"Introduction: Adolescents spent more time engaging in sedentary behavior in recent years, such as prolonged sitting, using smartphones, and watching TV. More importantly, excessive sedentary time is harmful to adolescent health, for example, resulting in obesity, cardiovascular disease, or depression. However, few studies systematically examined empirical findings of sedentary behavior and health in adolescents. The purpose of current study is to review the past studies of systematic reviews or meta-analyses related to sedentary behavior and health in adolescents, and further, we could have a better understanding. Methods: Several English and Chinese electronic databases were utilized for searching our target articles. Eighteen quantitative studies of systematic reviews or meta-analyses met the criteria for reporting the associations between sedentary behavior and health in adolescents. Results: Adolescents spent increased time in sedentary behavior, especially the screen-based sedentary behavior. Longer sedentary time was associated with more negative impact on both physical and mental health. The harmful effects of sedentary behavior were mostly reported in adolescents on these health indicators:“Cardiovascular & Metabolic Diseases,”“Fitness,”“Body Composition, Overweight, & Obesity,”“Self-esteem,”“Psychological Well-being,”and“Depression.”Further, we discussed the underlying mechanisms of sedentary behavior to explore the causes of potential harm. Conclusion: Excessive sedentary time could have serious repercussions for adolescent health. However, more evidence-based studies are needed to promote adolescent health. Future research could improve the measure and distinction of sedentary behaviors. In addition, intervention/experiment, longitudinal, or large-scale prospective cohort studies will help better clarify the associations between sedentary behavior and health in adolescents." |
