MONDAY, Jan. 31, 2022 (HealthDay News) — Physical activity monitor (PAM)-based interventions are safe and effectively increase physical activity and moderate-to-vigorous physical activity, according to a systematic review and meta-analysis published online Jan. 26 in The BMJ<\/em>.<\/p>\n Rasmus Tolstrup Larsen, from the University of Copenhagen in Denmark, and colleagues conducted a systematic literature review to identify randomized controlled trials comparing interventions in which adults received feedback from PAMs with control interventions in which no feedback was provided.<\/p>\n Based on 121 trials (16,743 participants), the researchers found that PAM-based interventions showed a moderate effect (standardized mean difference [SMD], 0.42) on physical activity, equivalent to 1,235 daily steps. Furthermore, PAM had a small effect (SMD, 0.23) on moderate-to-vigorous physical activity, equivalent to 48.5 weekly minutes. However, the effect of PAM on sedentary time, equal to 9.9 daily minutes, was insignificant.<\/p>\n “This study provides evidence for using physical activity monitors for enhancing physical activity and moderate-to-vigorous physical activity,” the authors write. “Large scale studies and studies investigating sedentary time in general, especially among overweight participants, are needed to clarify evidence gaps identified here.”<\/p>\n
