BACKGROUND: Physical inactivity is common in older age, yet increased activity benefits older people in terms of preventing chronic disease and maximising independence. Health coaching is a behaviour change intervention that has been shown to increase physical activity in clinical populations. This systematic review and meta-analysis investigated the effect of health coaching on physical activity, mobility, quality of life and mood in older people. METHODS: Medline, Embase, CENTRAL, PsycINFO, PEDro, SPORTDiscus, LILACS and CINAHL databases were used to identify randomised controlled trials which evaluated the effect of health coaching on physical activity (primary outcome) among people aged 60+. Secondary outcomes were mobility, quality of life and mood. We calculated standardised mean differences (SMDs, Hedges' g) with 95% CIs from random effects meta-analyses. RESULTS: 27 eligible trials were included. Health coaching had a small, statistically significant effect on physical activity (27 studies; SMD 0.27; 95% CI 0.18 to 0.37; p < 0.001). There was no evidence of an effect of health coaching on mobility (eight studies; SMD 0.10; 95% CI -0.03 to 0.23; p = 0.13), quality of life (eight studies; SMD 0.07; 95% CI -0.06 to 0.20; p < 0.05) or mood (five studies; SMD 0.02; 95% CI -0.12 to 0.16; p = 0.83). CONCLUSIONS: Health coaching significantly increased physical activity in people aged 60+. There was no evidence of an effect of health coaching on quality of life, mobility and mood, so different approaches may be required to impact on these outcomes.
