Core outcome set for behavioural weight management interventions for adults with overweight and obesity: Standardised reporting of lifestyle weight management interventions to aid evaluation (STAR‐LITE)

Abstract

Behavioural weight management interventions in research studies and clinical practice differ in length, advice, frequency of meetings, staff, and cost. Few real-world programmes have published patient outcomes and those that have used different ways of reporting information, making it impossible to compare interventions and develop the evidence base. To address this issue, we have developed a core outcome set for behavioural weight management intervention programmes for adults with overweight and obesity. Outcomes were identified via systematic review of the literature. A representative expert group was formed comprising people with experience of adult weight management services. An online Delphi process was employed to reach consensus as to which outcomes should be measured and reported and which definitions/instruments should be utilised. The expert group identified eight core outcomes and 12 core processes for reporting by weight management services. Eleven outcomes and five processes were identified as optional. The most appropriate definitions/instruments for measuring each outcome/process were also agreed. Our core outcome set will ensure consistency of reporting. This will allow behavioural weight management interventions to be compared, revealing which interventions work best for which members of the population and helping inform development of adult behavioural weight management interventions.

Sexual function and dysfunction among women with anorexia nervosa: A systematic scoping review

“…We recommend that the ED research community may benefit from the development of an agreed standardized set of outcomes, known as “core outcome sets” (COS). A COS (see Mackenzie, Ells, Simpson, & Logue, (2020) for an example in the field of behavioral weight management interventions for adults with obesity) can be used as the minimum required to be reported for any study or trial. This enables other researchers to combine and compare the results of studies, over time, and from different countries and might comprise a primary set of eating‐related outcomes and measures relevant to the assessment of sexual function and dysfunction in individuals experiencing eating‐related difficulties.…”

Tackling reporting issues and variation in behavioural weight management interventions: Design and piloting of the standardized reporting of adult behavioural weight management interventions to aid evaluation (STAR‐LITE) template

“…Effective recommendations can only be made in the presence of well‐reported RCTs ‐ transparent descriptions of which are needed to inform the evidence‐base of ‘what works’ for specific participants, thus shaping real‐world BWMIs. STAR‐LITE was designed to complement a comprehensive list of core outcomes, developed through expert consensus, that should be reported by both weight management trials and real‐world interventions to facilitate comparisons of intervention effectiveness 19 …”

“…The initial design phase brought together several published resources ‐ including similar reporting tools, 11,15,22‐24 intervention mapping reports, 2,6,15 NICE guidance and related commissioner feedback 5,15 ‐ to identify the key components required for detailed capture of BWMI delivery data (Table 1). Template creation intended to complement a pre‐defined core outcome set for BWMI reporting, 19 whilst aiming to address gaps in NICE knowledge 5 and areas of uncertainty via specific item inclusion.…”

“…In order to improve overall BWMI reporting quality with regard to consistency, clarity and completeness, an effective and specific solution must be offered. In 2020, a comprehensive, 24‐item 'core outcome and corresponding definition/instrument set' gathered using expert consensus was published to improve BWMI outcome reporting 19 . This list of outcomes (defining which should be measured and how) aimed to resolve uncertainty in decision making by presenting BWMI outcome information equally across all interventions.…”

The effect of workplace lifestyle programmes on diet, physical activity, and weight‐related outcomes for working women: A systematic review using the TIDieR checklist

“…On the other hand, better quality studies demonstrated smaller effects compared with poorer quality studies, and the authors did not include studies with participants over 25 kg/m 2 ,69 which may impact the ability to transfer these findings into real-world settings. As recently highlighted, formation of a clear evidence base for behavioural interventions is often hindered by erratic implementation and reporting of outcomes 70. Thus, it is recto demonstrate an effect for PA and weight outcomes compared with PA-only interventions.…”
