The majority of interventions that targeted food intake only (80%) or both food intake and physical activity (78%) were either cost-effective or cost-saving. On the other hand, interventions which only targeted physical activity were found to be not cost-effective. This is likely related to the limited number and scope of the specific interventions related to physical activity evaluated in the previous ACE projects. Most commonly, policy interventions targeting physical activity are more difficult to evaluate due to the difficulty in gathering conclusive evidence on effectiveness.
