Effectiveness of pedometer- and accelerometer-based interventions in improving physical activity and health-related outcomes among college students: A systematic review and meta-analysis

Background Although the pedometer- and accelerometer-based interventions (PABI) have demonstrated efficacy in improving physical activity (PA) health-related outcomes, dearth of empirical evidence college students warrants further investigation. Objective This systematic review meta-analysis aim to examine effects PABI on PA outcomes among students. Methods PubMed, Web Science, Embase, Cochrane Library, PsycINFO were searched for relevant literature from inception 20 February 2022. Randomized controlled trials (RCTs) conducted with increase objectively measured as primary outcome included this study. Results A total nine RCTs 527 participants The combined results showed that significantly improved (standardized mean difference = 0.41, 95% confidence interval (CI): 0.08, 0.74, P 0.016) contributed weight loss (mean differences (MD) −1.56 kg, CI: −2.40 −0.73 < 0.01), lower body mass index (MD −0.33 kg/m 2 , −0.66 0.00 0.05) compared control group, but no significant observed improvements fat (%) exercise self-efficacy.

Conclusions was found be promoting Future research is needed explore long-term characteristics multiple intervention models.
