A Systematic Review and Meta-Analysis of the Efficacy of Physical Activity Interventions among University Students

Inadequate physical activity (PA) among university students, a growing concern, hinders their holistic health development and the formation of healthy habits. Current evidence regarding the impact of interventions to promote PA in this group remains inconclusive. Through a systematic review and meta-analysis, this study aims to evaluate the efficacy of PA interventions in promoting PA among university students. A search of six electronic databases up to 30 June 2023 was conducted to identify randomized controlled trials (RCTs) assessing PA interventions in university students. Thirty-one RCTs were included for systematic review and meta-analysis. The eligible studies' quality was assessed via the Cochrane Collaboration tool for evaluating the risk of bias. The results indicated a significant increase in total PA (TPA), moderate-to-vigorous PA (MVPA), and step counts at post-intervention compared to control groups, with effect sizes approaching large for MVPA and an increase of 19,245 steps per week. TPA also showed significant improvements during follow-up periods from three weeks to 12 months. Subgroup analyses revealed significant intervention effects across all subgroups, with the subgroups of post-COVID and sample sizes <= 100 showing larger effect sizes within their respective group. This review identified that interventions could enhance TPA, MVPA, and step counts among university students, with sustainable effects on TPA, while further research is needed for other outcomes. The university environment is conducive to PA interventions, and future interventions integrating e-health with in-person modes, coupled with matched theories and behavior change techniques, show promise. This review protocol has been registered on the platform of the International Prospective Register for Systematic Reviews (PROSPERO, CRD42023486749).
