  1. APPLE Schools = Alberta Project Promoting active Living and healthy Eating Schools; DQI = Diet Quality Index; PAQ-C = Physical Activity Questionnaire for older Children
  2. a APPLE Schools were surveyed annually from 2008 to 2010; therefore analysis included additional measurements from 2009
  3. b Estimates weighted to be representative of the grade 5 Alberta student population
  4. All estimates were adjusted for child's gender, household income, parental education, and rural residency. OR (Odds Ratio) were from multilevel logistic regression of obesity. β's were from multilevel linear regression representing the association of CSH programming with changes in consumption of fruits and vegetables, DQI score, dietary energy intake, and PAQ-C score. The reference category for all outcomes is 2008 baseline observations. All dietary outcomes were further adjusted for energy intake. The intervention effect was calculated using an interaction term between APPLE Schools (Yes/No) and year of observation (2008/2010). To facilitate interpretation of results, the odds of being obese was calculated from the adjusted multilevel models and converted into a probability by using the relation Prob = Odds/(Odds + 1). Data collected in 2009 in APPLE Schools was included in the multilevel regression analysis. However, 2009 observations were omitted from analyses comparing APPLE Schools with the provincial sample, as 2009 observations were not available for Alberta schools other than APPLE Schools
