Across 19 randomised trials in adults aged 55 to 70, physical activity programmes produced a small but real increase in activity measured at least 12 months later. Programmes that gave people feedback on their own behaviour looked more effective, while printed materials and simple information looked less effective.

What it shows: Decent evidence that these programmes work modestly: results pooled from 19 trials in adults aged 55 to 70, all with activity checked at least a year later. The feedback and leaflet findings come from comparisons between subsets of trials, so treat them as promising leads rather than proof.Meta-analysis · Health Psychol Rev
