Pooling 26 randomised trials in 4129 older adults, multicomponent digital health programmes raised daily steps by 822.8 per day and moderate-to-vigorous activity by 45.9 minutes a week. Sedentary time, light activity and total activity showed no statistically significant change.

What it shows: Reasonably strong on brisk activity, weaker on steps: results pooled from 26 trials in 4129 older adults, with certainty rated moderate for moderate-to-vigorous activity and low for everything else. The trials disagreed a lot and many combined the technology with human coaching, so the app or tracker alone cannot take the credit.Meta-analysis · J Med Internet Res
