Systematic review and meta-analysis of smart-technology vs. face-to-face physical activity interventions in older adults (Preprint) Journal Articles

This is a systematic review of randomized controlled trials and a meta-analysis comparing smart-technology to face-to-face physical activity (PA) interventions, in community-dwelling older adults, mean age greater than or equal 60 years.

To determine the effect of smart-technology interventions compared to face-to-face PA interventions on PA and physical function in older adults. Our secondary outcomes were depression, anxiety, and health-related quality of life.

We searched four electronic databases from inception to February 2021. Two independent reviewers screened titles/abstracts, full texts, and performed data extraction and risk of bias assessments using the Cochrane risk of bias tool. GRADE was used to evaluate the quality of the evidence. We provided a narrative synthesis on all included studies and, where possible, we performed meta-analyses for similar outcomes.

19 studies with a total of 3455 patients were included. Random-effects meta-analyses showed that smart-technology interventions resulted in improved step count (mean difference 1440 steps, 95% confidence interval (CI) 500, 2390) and total PA (standardized mean difference 0.17, 95% CI 0.02, 0.32) compared to face-face interventions. The quality of the evidence for the effects of smart-technology interventions was very low based on GRADE criteria. There was no difference between groups for measures of physical function.

Interventions that include smart-technology may improve daily step counts by an average of 1440 steps in community dwelling older adults, however the quality of the evidence was very low. Future studies are needed to improve the certainty of results.
