  1. The Public Health Burden of Physical Inactivity in Canada Peter T. Katzmarzyk, PhD School of Kinesiology and Health Science York University

  2. Prevalence of Risk Factors Among Canadian Adults

  4. Annual Direct Medical Costs of Physical Inactivity: United States No Physical Limitations Physical Limitations All Subjects Pratt et al. Physician Sports Med 2000;28:63-70.

  5. Projected U.S. Hospital Admissions in 20 years Smoking: 8.9% reduction Physical Inactivity: 4.6% reduction *Allowing for a 10-year lag in health benefits Russell et al. Am J Prev Med 2001;20:26-34.

  6. Major Physical Activity-Related Diseases • Coronary Heart Disease (CHD) • Stroke • Hypertension • Colon Cancer • Breast Cancer • Type 2 Diabetes • Osteoporosis

  10. 10% Change in Inactivity • Reducing levels of physical inactivity from 62% to 56% would result in $150 million a year in savings Katzmarzyk et al. CMAJ 2000;63:435-1440

  11. The cost estimates are direct costs: • hospital services • physician care • drugs • health research • The indirect costs are larger: • time off work • loss of productivity

  12. Summary of Burden of Physical Inactivity • $2.1 billion, or 2.5% of total direct health care costs are attributable to physical inactivity • physical inactivity is responsible for 21 000 premature deaths a year • a reduction in physical inactivity of 10% would result in $150 million in savings a year

  13. Conclusions • Physical inactivity is a substantial public health burden in Canada • The surveillance of physical activity patterns remains a public health priority • Aggressive public health campaigns against physical inactivity are warranted • Governments need to create and appropriately resource public policies that will encourage systemic change and stem the growth of physical inactivity at all ages
