Effects of exercise interventions on Internet addiction among college students: A systematic review and meta-analysis of randomized controlled trials

Abstract

BackgroundInternet addiction (IA) has gradually emerged as a significant public health concern, especially among college students. This study aims to systematically investigate and quantitatively analyze the effects of exercise interventions on IA among college students and provides an objective assessment of the available evidence. For this study, IA is defined as compulsive, excessive Internet use, including via mobile phones, that disrupts daily life and causes significant distress, and we combine Internet addiction and mobile phone addiction in our analysis to provide a comprehensive understanding of this phenomenon. MethodsThe search for eligible studies was conducted from inception until May 2024 across various databases including Web of Science, PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wan Fang. The risk of bias within the included studies was assessed utilizing the Cochrane Collaboration’s risk of bias tool, while methodological quality was evaluated using the modified Jadad Scale. FindingsA meta-analysis of 19 pairwise comparisons showed that exercise interventions significantly reduced the total IA scores (g = −1.25). Furthermore, the interventions resulted in significant reductions in anxiety (g = −1.30), loneliness (g = −1.57), stress (g = −0.77), inadequacy (g = −1.77), mental health (g = −1.08), fatigue (g = −0.66), and depression (g = −0.56). ConclusionsExercise interventions showed efficacy in decreasing levels of IA and alleviating psychological symptoms in college students with IA. The optimal types of exercise for college students suffering from IA are open motor skill and the combination of both open and closed skill. However, future work is needed given the limited randomized controlled trials and the high heterogeneity of the included studies.
