  8. SEDENTARY BEHAVIOUR IN CHILDREN 8-13 yrs

  9. Trends in Households with Entertainment Equipment that Promotes Sedentary Behaviour cable one TV 2+TV VCR/DVD computer internet Statistics Canada, 2001; 2004

  10. “Contemporary obesity is a natural and appropriate response to the environment in which we live.”Dr. James Hill

  11. SOLUTION“Back to the Basics”

  12. BUILT ENVIRONMENT • “New Urbanism” • creating places people want to be not escape from • De-emphasis on autodependency • Structural approaches • listen to biology and nature, don’t direct them • de-prescribe, de-institutionalize our approach • Movement to more traditional street pattern • large sidewalks, narrow streets, attractive streetscape • people focus, not auto focus • makes communities more “walkable”

  13. DON’T BE FOOLED!! A structured exercise session does not replace 23+ hrs/day of SLOTH-LIKE BEHAVIOUR!

  14. A LITTLE MEANS A LOT!THE CASE OF THE TV REMOTE • Average age 78 years • 20 years x 52 wks x 25 hrs/wk = 26,000 hrs of TV • 58 years x 52 wks x 12.5 hrs/wk = 37,700 hrs of TV • (26,000 + 37,700) x 5 CC/hr = 318,500 CC in lifetime • 318,500 x 0.5 kcal / CC = 159,250 kcals • 159,250 / 3,500 kcal / lb of fat • 45.5 pounds of fat!!!

  15. Just how lazy are we? • Remote control fireplaces • Remote control remote control locators • Voice activated controls in cars / houses • Drive through funeral homes • Drive through banking • Drive through libraries

  16. RESULTSDirectly Measured Physical Activity • Old Order Mennonites • ↑ average movement counts per day • ↑ minutes of moderate physical activity (3-6 METS) • ↑ minutes of MVPA (3+ METS) • ↑ total daily energy expenditure Tremblay et al., MSSE, 2005

  17. Despite having no physical education, no institutionalized sport, and low socioeconomic status, Old Order Mennonite children are more active than children living a contemporary Canadian lifestyle. Tremblay et al., MSSE, 2005

  18. “In 1900 people were paid to be physically active,in 2000 people need to pay to be physically active.” Dr. Frank Booth

  19. What about“incidental movement”or“lifestyle embedded activity”or“DOMESTIC RECREATION”?

  20. Tremblay and Willms. Int J Obese, 2003

  21. Between 1981 and 1997 children’s free playtime dropped by an estimated 25%, and this change seems to be driven by increases in the amount of time children spend in structured activities. Hofferth and Sandberg. Children at the Millennium: Where have we come from, where are we going? 2001

  22. “we demonstrate why play, and particularly active, unstructured, outdoor play, needs to be restored in children’s lives” “we suggest the term “play”, not the terms “physical activity”, “exercise”, or “sports”, be used to promote movement in young children” Burdette and Whitaker. Arch. Pediatr. Adolesc. Med., 159:46-50, 2005

  23. BACK TO THE BASICSdemystifying the message • Eat a balanced diet, with a wide variety of foods, consumed in moderation • Moderate calories from beverages – chose water, with milk daily • Move more – get active, any way-everyday • Get sufficient, quality, regular sleep • Maintain a network of family and friends • Take action to promote and demand healthy living environments

  24. YOUR CHALLENGE! • Reduce time reference from an hour to a minute • Reduce activity reference from 200 kcal to 2 kcal • Reduce exercise reference to a few muscle contractions • Reduce autodependency • Reduce financial dependency • Reduce reward (food, awards, prizes) dependency • Reduce institutional approaches and dependencies • Reduce nature-deficit disorder
