- Any explanatory notes
- What action should they take?
Research studies and trials of lifestyle weight management programmes for children and young people who are obese or overweight should:
- Standardise outcome measures to assess effectiveness. Outcomes should be reported on an 'intention to treat' basis (as opposed to reporting outcomes for programme completers only). They should include:
- changes in BMI z score, as the primary outcome measure
- factors that affect weight (matching these to the intervention objectives) for example, measures of self-efficacy, changes in diet, physical activity and time spent being sedentary and measures of wellbeing.
- Standardise the time points at which outcome measures are reported and followed up. They should include, as a minimum: at baseline, completion of the intervention and at 6 months and at 1 year after completing the intervention.
- Report in detail the components of the intervention. This should include: what is done, to whom, by whom, in which setting, and when and how?
- Include an appropriate comparator group and report the components above. If a randomised controlled trial is not possible, alternative research designs should be considered.
- Report attrition (drop-out) rates, follow up non-completers and investigate the causes of attrition. Also should investigate the causes of low uptake and how these might be addressed.
- Be sufficiently powered to detect effects.
- If possible use only standardised validated tools (appropriate for the study sample) to collect data, for example, a validated food frequency questionnaire to investigate dietary intake. If validated tools for secondary measures do not exist, a tool to measure the outcome (for example, physical activity) should be developed as part of the study.
- Include the collection and analysis of qualitative data to allow a process evaluation of the intervention. These data should include the referral process and experiences of both programme staff and participants.
- Include the collection of cost data to allow cost effectiveness to be evaluated.
- Report any unexpected effects or outcomes.
