Description
Summary:BackgroundThe prevelance of depression in older people is high, treatment isinadequate, it creates a substantial burden and is a public healthpriority for which exercise has been proposed as a therapeuticstrategy.AimsTo estimate the effect of exercise on depressive symptoms among olderpeople, and assess whether treatment effect varies depending on thedepression criteria used to determine participant eligibility.MethodSystematic review and meta-analysis of randomised controlled trials ofexercise for depression in older people.ResultsNine trials met the inclusion criteria and seven were meta-analysed.Exercise was associated with significantly lower depression severity(standardised mean difference (SMD) =–0.34, 95% CI –0.52 to –0.17),irrespective of whether participant eligibility was determined byclinical diagnosis (SMD =–0.38, 95% CI –0.67 to –0.10) or symptomchecklist (SMD =–0.34, 95% CI –0.62 to –0.06). Results remainedsignificant in sensitivity analyses.ConclusionsOur findings suggest that, for older people who present with clinicallymeaningful symptoms of depression, prescribing structured exercisetailored to individual ability will reduce depression severity.
