What is the role of smartphones on physical activity promotion? A systematic review and meta-analysis
To identify and evaluate the effect of interventions that used cell phones as a means to promote physical activity (PA).
The databases searched were MedLine/PubMed, Scopus, SPORTDiscus, PsycINFO, Science Direct, Lilacs, and SciELO. After removing duplicates, applying exclusion criteria, and checking the reference lists, 45 studies were reviewed. The Downs and Black (D&B) scale measured methodological quality, and a random effect model was used to compute the meta-analysis of PA by the reported unit (minutes per day or steps per day), delivery agent (application (APP), SMS, or other), and PA measurement (questionnaire, accelerometer, pedometer).
Mobile phone-based PA interventions were efficient in increasing both minutes [10.49; CI (3.37–17.60); p = 0.004] and steps per day [735.17; CI (227.72–1242.61); p = 0.005] in adults when compared to baseline. Furthermore, APP-based interventions were able to increase the number of steps (p = 0.04) and minutes per day of PA (p = 0.04) in adults. Also, 85% of included manuscripts were classified as moderate- to high-quality articles.
Mobile phone-based PA interventions, inclusive those delivery by APP, were effective to increase minutes and steps per day in adults.
