  1. The Cost-Effectiveness of Educational Interventions Michele Cecchini Health Division

  2. The obesity epidemic • Obesity has become a top public health priority and it is set to increase further • Environmental influences on lifestyles played a major role, fuelled by a “social multiplier” effect • OECD Governments very active in last 5-10 years implementing programmes to improve diets and physical activity • Limited evidence on the effective of interventions and virtually no evidence of their efficiency and distributional impact

  3. Modelling Approach • Generalized cost-effectiveness analysis • Acknowledges global budget constraints • Allows the comparison of interventions within and outside the health sector • Identifies the mix of interventions that generates the largest health gain • Microsimulation model • “Causal web” of risk factors influences the development of diseases • European population (gender, age, SES) • 100 year perspective • Potential policies assessed keeping constant all other parameters

  11. Conclusions • Prevention, educational interventions included, is a good way of spending money to improve health • Interventions, especially those aimed at children, may take a long time to make an impact and reach favourable cost-effectiveness ratios • Impact on health expenditure is limited relative to intervention costs • Some private sector interventions are cost-effective and may shift costs away from government budgets www.oecd.org/health/prevention
