<sec> <title>UNSTRUCTURED</title> <p>Importance Obesity is one of the biggest drivers of preventable chronic diseases and healthcare costs in major developed countries. A number of studies have been conducted on the efficacy of commercial devices in weight management, however this review focuses on how these devices are perceived by users, which few other studies had investigated. Objective To review the efficacy of wearable technology implemented for weight management from a user feedback perspective. This is a key consideration because user satisfaction is a prominent factor that influences technology adoption. Evidence Review Online databases including Pubmed/Medline, Scopus, Embase and the Cochrane library were systematically searched for literature published from 2008 onwards. All types of studies conducted on overweight (BMI>25) or obese (BMI>30) adults, where wearable device implemented for weight loss was used in the intervention, and where qualitative data were collected about participant’s feedback on the intervention were included. The methodological quality assessment was performed using critical appraisal criteria and data were extracted onto a data extraction sheet and analysed into themes. Findings Data from 19 eligible studies (including RCT (n=5), non-randomised studies (n=6), qualitative studies (n=5) and reviews (n=3)) shows that mixed perceptions exist for different constructs of wearable technology, which suggests the different suitability of each wearable technology intervention for different individuals and in different contexts and reflects that fact that very few intervention select participants according to the participant’s motivation source. In addition, very few wearable technology interventions included thorough qualitative analysis of the participant’s view on important features of the intervention that has made it a(n) (un)successful weight loss intervention. Conclusions and Relevance This study highlighted the importance of determining the type of intervention most suitable for an individual before the intervention is implemented, which may lead the participants to a suitable intervention that would prove most effective to them. Further research developing a user-centred tool for obtaining comprehensive user feedback is also recommendable. Ethics and dissemination As data collection was executed via published literature, ethical approval will not be required for this review.
