Twenty-three studies targeted adults (17 showed significant health improvements) and four studies targeted children (two demonstrated significant health improvements). Twenty-one studies targeted physical activity (14 showed significant health improvements), 13 studies targeted diet (seven showed significant health improvements) and five studies targeted sedentary behaviour (two showed significant health improvements). More studies (n = 12; 63%) of those reporting significant effects detected between-group improvements in the health behaviour or related health outcomes, whilst fewer studies (n = 8; 42%) reported significant within-group improvements. A larger proportion of multi-component interventions (8 out of 13; 62%) showed significant between-group improvements compared to stand-alone app interventions (5 out of 14; 36%). Eleven studies reported app usage statistics, and three of them demonstrated that higher app usage was associated with improved health outcomes. Conclusions: This review provided modest evidence that app-based interventions to improve diet, physical activity and sedentary behaviours can be effective. Multi-component interventions appear to be more effective than stand-alone app interventions, however, this remains to be confirmed in controlled trials. Future research is needed on the optimal number and combination of app features, behaviour change techniques, and level of participant contact needed to maximise user engagement and intervention efficacy.]]> Wed 11 Apr 2018 16:16:34 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4668 Wed 11 Apr 2018 14:31:43 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18112 Wed 11 Apr 2018 13:29:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19429 Wed 11 Apr 2018 10:24:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25317 Wed 11 Apr 2018 10:00:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48113 Wed 06 Mar 2024 14:54:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5370 Sat 24 Mar 2018 07:43:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:258 Sat 24 Mar 2018 07:42:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41796 Fri 12 Aug 2022 12:24:48 AEST ]]>
