Behavioural Interventions for Severe Obesity Before and/or After Bariatric Surgery: a Systematic Review and Meta-analysis

Stewart, Fiona, Avenell, Alison·2016·Obesity Surgery

Abstract

Background Significant, sustained weight loss through conventional, non-surgical interventions is often unattainable for people with severe obesity (e.g. BMI ≥40 or ≥35 kg/m(2) with co-morbidities). Bariatric surgery is effective in treating severe obesity, but surgery alone without additional behaviour change management may not result in optimum long-term weight loss and maintenance. This systematic review and meta-analysis of randomised controlled trials evaluated the effectiveness of lifestyle interventions before and/or after bariatric surgery.Methods MEDLINE, Embase, Cochrane Central Register of Controlled Trials and clinical trials registers were searched for eligible studies. Key journals were handsearched. Last search date was on December 2014. Eligible interventions had the explicit aim of changing behaviour related to diet and/or physical activity, starting within 12 months of surgery, either pre- or post-operatively, and with at least 6 months' follow-up. The primary outcome was weight change; secondary outcomes included surgical complications, quality of life and changes in co-morbidities. Random effect meta-analyses were undertaken. Study quality was assessed with the Cochrane Collaboration's risk of bias tool.Results Eleven trials met the inclusion criteria. Behavioural interventions appear to improve weight loss at 12 months after bariatric surgery. Secondary outcome data were lacking and weight outcomes were reported inconsistently. Overall, the methodological quality of the identified trials was low.Conclusions The strength of evidence is limited by the relatively small number of trials identified and by their low methodological quality and short follow-up duration. Well-designed randomised controlled trials (RCTs) with long-term follow-up are required.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
