  2. Increasing Prevalence of Obesity in Canada Estimated Prevalence of Obesity in the Canadian Population From 2003-2011, Adjusted Self-reported Year % 2003 22.3 2005 22.8 2007 23.8 2008 24.2 2009 24.9 2010 25.1 • 25.3 Gotay et al. Updating the Canadian obesity maps. CJPH 2013; 104:e64-e68

  3. High Costs • Estimated $4-6 B per year in direct & indirect costs • Increasing prevalence of obesity • Increasing prevalence of hypertension, DM, CVS, cancer, mental health, musculoskeletal problems • Unsustainability of publicly funded healthcare • Reduced productivity, competitiveness

  4. Complex ‘Wicked’ Problem

  5. Leverage Points • Reduce calorie consumption – priority for action • Increase physical activity

  6. Reducing Calorie Consumption • Food and beverage industry: create addictive combinations of sugar, fat and salt • Spend $ billions on marketing – children a target* • Use same strategies as tobacco – deny the problem, resist taxation and regulation through a ‘voluntary’ approach, stress ‘individual choice’ *The extraordinary science of addictive junk food. Moss,M. NYTimes Feb,’13

  7. Market Failure • Externalities- while making profits for shareholders, food & beverage corporations have no responsibility for the downstream healthcare costs of obesity • Asymmetry of info – children are naïve and don’t have full reasoning power • Requires government intervention – this not ‘nannyism’

  8. Promising Policy Interventions to Reduce Junk Food Consumption • Significant tax on SSBs (could use revenue to subsidize healthy foods & beverages)* • Improve nutrient labeling at point of purchase*/consumption; warnings • Restrict advertising, sponsorship* • Restrict sales of junk food (in and around schools*, checkouts) • Salt reduction strategy *BCHLA Recommendation

  9. Increase Consumption of Healthy Food & Beverage • Subsidies for fruit and veg in remote, rural, disadvantaged communities* • Local food programs and policies* – urban agriculture, farmer’s markets • Comprehensive community obesity prevention - EPODE

  10. Increase Physical Activity • Healthy built environment: parks, arenas, pools, gyms, bike paths, hiking trails, density, connectivity, safety* • School programs* • Comprehensive community programs*
