A review of the evidence base for modelling the costs of overweight,obesity and diet-related illness

A review of the evidence base for modelling the costs of overweight, obesity and diet-related illness for Scotland, and critical appraisal of the cost-effectiveness evidence base for population wide interventions to reduce overweight, obesity and diet-related illness

The specific objectives were to provide a review of the evidence base relating to the costs of overweight, obesity and diet-related illness for Scotland, and to review and critique the cost-effectiveness evidence base for population wide interventions affecting diet to reduce overweight, obesity and diet-related illness.

This research developed an improved understanding of the wider economic consequences of diet-related health, by describing and critiquing existing evidence of estimates of cost and cost-effectiveness developed to tackle overweight, obese and diet-related disease in Scotland.

Outcome and Translation

The international literature provides evidence for the cost-effectiveness of a range of population level interventions to improve diet and obesity.  However, these are modelling studies rather than evaluations of interventions post-implementation and specific estimates of the population impact for Scotland are lacking.  It is recommended that any future estimates for Scotland should be developed by reviewing evidence from effectiveness studies that have tracked longer term effects of interventions on weight change and health.
