Abstract

Introduction: The prevalence of obesity increases worldwide. The use of technology-based interventions can be beneficial in weight loss interventions. Objectives: This review aims to provide insight in the effectiveness of technology-based interventions on weight loss and quality of life for patients suffering overweight or obesity compared to standard care. Methods: Data was searched from the earliest date of each database up to February 2015. Cochrane Collaboration�s tool for assessing risk of bias was used for rating the methodological quality. Results: Twenty six trials met inclusion criteria. Twelve studies showed significant effects on weight loss compared to controls. Most interventions used a web-based approach (42%). Interventions were screened for five technical key components: Self-monitoring, counsellor feedback and communication, group support, use of a structured program and use of an individually tailored program. No significant results for quality of life were found. Outcomes on program adherence were reported in six studies. No significant results were found between weight loss and program adherence. However, interventions with a technological component did show higher adherence rates compared to control groups. Conclusion: Evidence is lacking about the optimal use of technology in weight loss interventions. However, when the optimal combination of technological components is found, technology-based interventions can be a valid tool for weight loss. Furthermore, more outcomes on quality of life and information about the effect of technology-based intervention after bariatric surgery are needed.
