Title

The Association of mHealth Features with User Engagement in Weight Management Interventions: A Literature Review

Abstract

In fighting obesity, mobile health (mHealth) based weight-loss management interventions utilizing a combination of behavior change techniques (BCTs) could be effective. However, mHealth apps have a high rate of disengagement, which has been a concern. This paper aimed to determine how mobile app features trigger user engagement to facilitate behavior change that improves weight management. We conducted a systematic review of published systematic literature reviews on mHealth weight management interventions following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. We illustrated the connection between features and engagement constructs presented in the literature. Many features could potentially be effective in facilitating weight management but they need to be integrated to enhance engagement. At the same time, evidence is lacking to strongly prove associations between features and engagement.
