The evidence statements from 2 reviews are provided by external contractors.
This section lists how the evidence statements link to the recommendations and sets out a brief summary of findings from the economic analysis.
A report on cost effectiveness considerations from a population modelling viewpoint was prepared by NICE instead of a review of economic evaluations and a modelling report.
The paper was based on a conceptual model relating to the weight changes of age and sex cohorts of the population over time, a format developed for modelling exercises in 3 previous NICE guidelines:
Overweight and obesity in adults: lifestyle weight management (see Overweight and obese adults – lifestyle weight management: economic modelling report)
Lifestyle weight management in children and young people (see Overweight and obese children and young people − lifestyle weight management services: economic modelling report)
Preventing type 2 diabetes: population and community interventions (see Preventing type 2 diabetes – population and community interventions: report on cost-effectiveness evidence and methods for economic modelling).
From the modelling undertaken in these reports, and given the absence of any substantive new data, brief advice interventions were inferred to be cost effective when their low cost was considered against the cost of weight management interventions.
