Effectiveness of web-based feedback interventions for people with overweight and obesity: systematic review and network meta-analysis of randomized controlled trials Varela Vázquez, Carmen Oda Montecinos, Camila Andrés, Ana Saldaña, Carmina Obesity Website Feedback Treatment Network meta-analysis Background: Web-based delivered interventions have become an innovative option to treat health problems, like obesity. The aim of this systematic review and network meta-analysis was to analyze the effectiveness of web-based behavioral treatments for adults with overweight and obesity. Web- based interventions and comparison interventions (traditional weight control programs) were classified according to the following feedback characteristics: frequency, personalization, and provider (human versus machine). Method: From the initial 1789 studies, 15 were included in this review. A network meta- analysis was conducted to analyze the efficacy of web-based programs with traditional interventions, considering direct and indirect comparisons. The main outcome was the weight loss mean difference (kg) between baseline and post- treatment. Heterogeneity and consistency assumptions were validated to conduct the network meta-analysis. Results: Network meta-analysis showed comparisons between different treatment options. The main results were that Intensive Contact Web-based programs were more effective than wait-list (Mean Difference − 1.86 kg; 95% Confidence Interval: − 3.61, − 0.12). Moreover, Intensive Contact Web-based programs were more effective than the other web- based options and self-help traditional interventions. However, the only significant comparison was Intensive Contact Web-based programs versus Guided Self-Help Web-based programs (Mean Difference − 4.31 kg; 95% Confidence Interval: − 5,22, − 3,41). Intensive Contact Web-based programs were the most effective treatment option according the obtained results, achieving the first place in the ranking provided by the network meta-analysis with 98.5% of probabilities. 2025-01-31T15:52:12Z 2025-01-31T15:52:12Z 2025-01-31T15:52:12Z 2021 info:eu-repo/semantics/article http://hdl.handle.net/10259/10136 10.1186/s40337-021-00432-6 2050-2974 eng Journal of Eating Disorders. 2021, V. 9, 75 https://www.doi.org/10.1186/s40337-021-00432-6 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional BMC
