Effectiveness of web-based feedback interventions for people with overweight and obesity: systematic review and network meta-analysis of randomized controlled trials

Abstract

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. Conclusions Intensive Contact Web-based interventions have obtained the first position in the ranking, proving the relevance of frequent, personalized, and professional feedback and their association with a better prognosis for people with overweight and obesity. These results provide relevant information to design more effective treatments for people with overweight and obesity, in a new format especially appropriate for the current situation.

The Effectiveness of eHealth Interventions for Weight Loss and Weight Loss Maintenance in Adults with Overweight or Obesity: A Systematic Review of Systematic Reviews

“…Funding information can be found in the Online Resource . Fourteen studies focused on eHealth interventions in a general sense [ 19 – 32 ], five on interventions delivered through mobile phones [ 33 ••, 34 – 37 ], and three on interventions combining eHealth and human-delivered care [ 38 •, 39 , 40 ]. One compared web-based interventions to mobile phone applications [ 41 ].…”

“…We rated two reviews as being of moderate methodological quality [ 6 , 37 ], 13 as low [ 19 , 20 , 23 , 25 – 27 , 29 , 31 , 32 , 33 ••, 34 , 38 •, 43 ], and 11 as critically low [ 21 , 22 , 24 , 28 , 30 , 35 , 36 , 39 – 42 ]. A detailed evaluation of each AMSTAR 2 criteria can be found in the Online Resource .…”

“…Beleigoli et al found those in the eHealth intervention to achieve better weight loss results than those on a wait-list (mean difference (MD) − 2.14 (− 2.65, − 1.64) kg, P < 0.001) [ 19 ]. Moreover, Varela et al reported that those in an eHealth intervention with professional feedback at least weekly reached the strongest outcomes compared to those on a wait-list (MD − 4.32 (− 5.08, − 3.57) kg, P < 0.001) while those in a mostly automated eHealth intervention reached slightly weaker results (MD − 3.23 (− 3.80, − 2.66) kg, P < 0.001) [ 32 ].…”

Effectiveness of Information and Communications Technology-Based Interventions for Obesity and Metabolic Syndrome

“… 28 Overseas, an intensive contact web-based program showed a remarkable effect on weight loss (mean, –4.31 kg; 95% CI, –5.22 to –3.41). 29 These results suggest that ICT-based interventions can be most effective when provided multi-dimensionally and accompanied by therapist feedback and support.…”

Estudio de las notas del traductor y su recepción en la traducción literaria del japonés al castellano de Takekurabe

“…A continuación, se diseñó un cuestionario en línea en Google Forms para recabar la opinión de lectores acerca de las notas del traductor en general. Si bien los cuestionarios en línea pueden dar problemas porque dificultan el control de la identidad de los informantes (Pit et al, 2014) o presentan un menor porcentaje de respuestas en contraste con otros métodos (Kwak y Radler, 2002), en general se consideran una buena alternativa (Varela et al, 2016) que suceden al introducir manualmente datos y analizarlos (Van Gelder et al, 2010;McPeake et al, 2014), permiten introducir opciones para evitar que haya respuestas sin responder o incompletas, ofrecen la información de forma más rápida para administrarla simultáneamente (Van Gelder et al, 2010), y suelen ser más económicos (Aerny-Perreten et al, 2015). Además, se consideró que el uso de cuestionarios en línea se había normalizado suficientemente entre parte de la población debido a la crisis sociosanitaria provocada por el COVID-19.…”
