Effectiveness of physical activity monitors in adults (2022)

This systematic review and meta-analysis identified 121 studies with 141 comparisons investigating the effect of PAMs (physcial activity monitors). The authors summarise the results from 16743 unique participants and provide low certainty of evidence for a moderate effect on physical activity equal to 1235 daily steps more, moderate certainty of evidence for a small effect on moderate to vigorous physical activity equal to 48.5 minutes weekly moderate to vigorous physical activity time more, and moderate certainty of evidence for a small but insignificant effect on sedentary time equal to 9.9 daily sedentary minutes less in the intervention groups.
