  1. Cost-effectiveness of a Physical Activity Awareness Campaign Jennie Petersen, MSc. Student Dept. of Community Health Sciences Faculty of Medicine University of Calgary

  2. VERB Awareness Campaign • VERB - Physical Activity Awareness Campaign • Target: Children 9-13 years old • National-level campaign implemented in 2002 in the USA • Two-year evaluation in 2004 (Huhman et al., 2007) • Purpose: Examine effect of VERB on children’s behaviour • Study design: Longitudinal cohort, n=2257 • Measurement tool: Youth Media Campaign Longitudinal Survey • Result: Significant dose-response relationship between ‘aware’ and ‘unaware’ children

  3. Research Questions 1) What is the cost-effectiveness (CE) of the VERB physical activity (PA) awareness campaign? 2) What are the implications of the results for Canada?

  4. Methods • Evidence from the VERB campaign was used to determine the CE of a PA campaign • Extrapolated results to 60 years of age and estimated: • Cases of CVD prevented • Net medical costs (cost-offsets) • Cost-Effectiveness Analysis (Modeling) • Compared PA campaign with ‘Do Nothing’ strategy • Adopted a health care payer perspective • Estimated (net) cost per case of CVD prevented

  5. Model

  6. Model 17% 29% 61% 81%

  7. Results • Cost of the VERB campaign • (US) $9,240 per 1000 children • Cases of no CVD • PA Campaign: 775.5 cases per 1000 children • Do Nothing Strategy: 772.9 cases per 1000 children • Difference: 2.6 per 1000 children • Lifetime medical costs • PA Campaign: (US) $33,414,000 per 1000 children • Do Nothing Strategy: (US) $33,495,000 per 1000 children • Difference: (US) -$81,000 per 1000 children • Net costs of the intervention • (US) -$71,760 per 1000 children … cost savings!

  8. Sensitivity / Scenario Analysis • Result remains robust to changes in: • Awareness levels • Probability of an active child becoming an active adult • Prevalence of CVD in active and inactive people • Campaign effectiveness • Result was not robust to changes in: • Medical Costs

  9. Assumptions … limitations • Difference in PA attributed solely to the campaign • Sedentary children remain sedentary as adults • PA behaviour doesn’t change over lifetime, except from adolescence into adulthood • Excluded health care costs associated with PA • Only included benefits of PA in preventing CVD

  10. Conclusions • VERB PA Campaign aimed at children appears highly cost-effective • Strength of this CE is limited by strength of evidence / assumptions used in the model • Results remain robust to changes in most assumptions … but not all • Relied on US data! … Implications for Canada?
