Physical activity interventions and depressive and anxiety symptoms among adolescents : a scoping review

Abstract: Background: Anxiety and depression disorders among adolescents are increasing globally and seriously endanger their health and quality of life. Having anxiety or depressive symptoms in adolescence can have serious consequences and even increase the risk of later adult disorder. Physical activity could be a good way to prevent this. However, an updated review on how and why physical activity interventions may be relevant for reducing and preventing symptoms of depression and anxiety among adolescents is needed. This study aims to study physical activity interventions that focus on the symptoms of depression and anxiety among adolescents. Methods: To bring together previous scientific research, a scoping literature review has been applied. A search was performed in PubMed database to identify studies and meta-analyses meeting the inclusion criteria. Finally references from recent published systematic reviews and meta-analysis were checked. Results: The search yielded a total of 5,091 records with additional 56 records identified through other meta-analyses and reviews. A total of fifteen articles were included for the final review. Most of the included studies showed that there was a significant difference in depressive score after the physical activity intervention. An improvement in anxiety symptoms was identified as well. Overall, 15-60 minutes of aerobics exercise 2-3 times/week, for a minimum of 8 weeks, led to feeling less anxious and depressive. In conclusion, physical activity interventions may be very beneficial for decreasing both depressive and anxiety levels among adolescents.
