Self-reported PA levels collected in 2002 from 764 adults ages 50 to 80+ living in a Canadian city are related to multiple environmental attributes. * PA measured by PASE (Physical Activity Scale for the Elderly) includes activities commonly engaged in by elderly people, including gardening, housework, and caring for others, in addition to walking and other leisure activities.

4. Since the 1970s, the percentage of children and youth ages 2 to 19 years who are obese has tripled. The increase is greatest among African-American and Low-income children.

5. The Surgeon General recommends that children engage in at least 60 minutes of moderate physical activity most days of the week. Yet, according to 2006 estimates, nearly 2/3 of adolescents do not meet this recommendation, based on self-reports. Eaton DK, Kann L, Kinchen S, et al. Youth Risk Behavior Surveillance-United States, 2005. Surveillance Summaries, [June 9]. Morbidity and Mortality Weekly Report 2006; 55(SS-5), 1–108.

6. Children who play video games that require physical activity can burn up to eight times as many calories as children who engage in sedentary screen time. For example, one study found that children burned 90 calories more per hour while playing Dance Dance Revolution than did children who played inactive video games.

7. A 2006 cross-sectional national study of 8th and 10th grade students* (N=39,011)found more black and Hispanic youth being overweight than white youth at most every socioeconomic (SES) level. Frequent exercise was associated with a lower likelihood of being overweight for all groups. referent *Based on self-reported data from the University of Michigan’s Monitoring the Future Project ** Defined as being at or above the 85th percentile Delva J, Johnston LD, O’Malley PM.

10. NHANES data from 2003-2004 show the percentage of youth ages 6 to 19 meeting recommended physical activity guidelines declines significantly with age. Troiano RP, Berrigan D, et al.

12. A study of children (N=333 from the Iowa Bone Development Study) found that children who were most active* at age 5 had significantly lower fat mass at age 8 and age 11 than children who were the least active at age 5. • *Minutes per day spent in moderate to vigorous physical activity (MVPA) measured with accelerometers • Janz KF, Kwon S, Letuchy EM, et al.

14. Adult Obesity Rates and Trends, 2009 Adult obesity rates continued to rise in 23 states. Rates did not decrease in any state. Thirty-one states have adult obesity rates above 25%. In Mississippi, Alabama, West Virginia, and Tennessee, adult obesity rates are above 30%. Trust for America’s Health.

15. Data from the 2000 to 2003 National Health Interview Survey reveal that all Hispanic groups were more likely to have no leisure-time physical activity (LTPA) than non-Hispanic Whites, and that there are significant differences in levels of no activity among Hispanic sub-groups.

16. Reduction in Calories Burned at Work is Related to Increase in Obesity since the 1960s A national study examined the relationship between the prevalence of obesity and reductions in calories burned during work from 1960 to 2006. The study predicted that, given a baseline weight of 76.9 kg in 1960-62 for men, a drop of 142 calories would result in an increase in average weight to 89.7 kg, which closely matched the actual average weight (according to NHANES data) of 91.8 kg in 2003-06. The results were similar for women. Church TS et al. Trends over 5 Decades in U.S. Occupation-Related Physical Activity and Their Associations with Obesity. PLoS ONE 2011; 6(5):e19657.
