title: [Effectiveness of web-based psychological interventions for weight loss--a systematic review].
abstract: Weight reduction is a core objective in the rehabilitation of somatic diseases. This systematic review aims to investigate the effectiveness of web-based psychological interventions for weight loss.Included were randomized controlled trials comparing web-based psychological interventions for weight loss with waiting list or usual care. Outcomes were body mass index (BMI), weight and waist circumference. Effect sizes were analyzed in random-effects meta-analyses.The search identified 5 trials. Subjects of the intervention group reduced their BMI (weighted mean difference--WMD = -0.49 [95%--CI: -0.95; -0.03]), weight (WMD = -1.32 [-2.59; -0.06]) and waist circumference (WMD = -2.35 [-3.18; -1.52]) significantly more than controls.Web-based psychological interventions are effective weight loss interventions. However, the effects are small and their clinical importance is limited.
