Global Obesity Epidemic1 • More than 400 million adults were obese in 2005 worldwide • Chronic diseases associated with obesity account for 60% of the 58 million deaths/year2 • Cardiovascular disease, diabetes, some cancers, chronic respiratory diseases 1http://www.who.int/mediacentre/factsheets/fs311/en/index.html; 2 Preventing Chronic Diseases: a Vital Investment: Geneva, World Health Organization 2005

Children not Immune3 • In 2005 at least 20 million children under five years old were overweight globally1 • Up to 80% of obese youth continue this trend into adulthood • Risk for chronic disease and premature mortality 3 LeBlanc CMA, Gomez J et al. Pediatrics ,2006;117:1834-1842

What are Some Co-morbidities of Obesity in Youth?3 • Type 2 diabetes • Obstructive sleep apnea • Nonalcoholic Fatty liver (NAFLD) • Polycystic ovary syndrome • Hypertension • Hyperlipidemia • Focal segmental glomerulosclerosis • Orthopedic complications • Depression/anxiety • Poor self-esteem, and lower health-related quality of life 3 LeBlanc CMA, Gomez J et al. Pediatrics ,2006;117:1834-1842
Why are Kids Overweight? • Excessive juice & pop • Low fruit/veggies • Low cereal fiber • Absence of family meal • Fast-foods: fat and energy • Mega-meals5 5 Newman C. National Geographic 2004;206(2): 46-60
Why are Kids Overweight? • Too muchTVwatching • Strongly linked to obesity4 • Inadequate physical activity (PA) levels6 • Canadian 5-17 year olds average 11,356 steps/day by pedometer • Need 12,000 -16,500 steps/day ~ 90 min mod-vigorous PA/day 6 CANPLAY: Physical Activity Monitor 2005. www.cflri.ca/eng/statistics/surveys/pam2005.php
Why Not Active Enough? • PA DAILY at home • TV, computer/video games • Unsafe environments • Recreational facilities • Inactive parents • PA DAILY at school • 17% Canadian schools(Elementary High) have daily PE by PE specialists7 7 Cameron C.

Benefits of Healthy Nutrition • Malnourished children have8 • ↓ Physical activity & endurance • ↓ Cognitive function & school performance • Greater frequency of ADHD • Omitting breakfast can interfere with learning even in well-nourished children • School breakfast programs9 • ↑ School attendance • ↑ Math test scores • Optimal growth & development • Obesity prevention 8FanjiangGCurr Opin Clin Nutr Metab Care. 2007 May;10(3):342-7; 9Powell, CA. Am J Clin Nutr 1998;68:873–9.
Benefits of Physical Activity • Aerobic PA ↓ Wt(obese kids)9 • Diet + exercise better than either alone10 • Lifestyle PA better than calisthenics or programmed aerobic exercise11 • Improved co-morbidities • Insulin resistance; fatty liver; dyslipidemias • ↑ Self esteem; ↓ anxiety & depression12 • May improve or not worsen academics13 9Owens S.

Research Summary • Schools are pivotal settings to promote healthy active living • Multifaceted programs implemented in multiple settings targeting behaviour change rather than isolated knowledge acquisition appear to work best • Dedicated PE with a variety of aerobic activities • Active recreation before, after and during school • Healthy food and drinks in cafeteria, vending machines • Parental and family involvement important
WHO Suggests • Set up a School/District Wellness Committee • Develop & implement policy • PA, food, curriculum, school health services • Monitor & evaluate • Process, output & outcome indicators • Involve stakeholders EARLY
Schools: Everyone Benefits from an Active Living Workplace • Trustees, Superintendents • Develop policy • Influential, secure resources, support staff, bridge with external groups • Principals • Leaders; promote & maintain wellness programs for staff & students • Teachers (Keyimplementers) • Require PE training, curriculum aligned with academic mandates, support from principal, sufficient time & resources • Students (Key recipients) • Should have a say in policy/programs
Parents & Extended Family • School health program can influence family behaviour at home • Students change parent behaviour • Parents can set a good example • Family can help with active living homework assignments • Family can encourage & take part in safe active transportation • Walking school bus • Family can support school health policy and programs • PTA • Family can lobby decision-makers to support health promotion in schools
Health Professionals: MDs • Provide families with office-based healthy lifestyle counseling • Time? Sufficient? • MD can set a good example • Support active school community • Sit on school/district wellness committee • Provide help with advocacy, research, monitoring, evaluation • Physicians can provide knowledge translation • MDs, health organizations, general public • Community wide education: Media • Letters to or meetings with key decision makers Dr. P. Nieman Marathon runner
Education & Health: United We Stand • Canadian Council on Learning 2008* • 6/10 Canadian adults have insufficient literacy skills to manage their health • Those with low health literacy 2.5 x likely to have fair-poor health • MDs consulted most (74%) for health-related information because of credibility • Need more training in using simple language • Media & family/friends consulted next (67%) but less credible– schools way down on list • Opportunity for MDs to learn from schools on messaging & schools to learn from MDs on health-related matters *http://www.ccl-cca.ca/CCL/Reports/LessonsInLearning/LinL20080306HowLowLiteracy…
Next Steps • Alberta School districts & health regions showing • Best practice examples • Workshops • Listen, learn, offer help • Create feasible action plans for your region • Network of MD champions • NEW MODEL • Local Region Province
