Difference between the Experimental I and II groups compared with the Control group at post-test, adjusting for the outcome measure at baseline and gender, baseline BMI and school.^‡

Data were collected in 2005–06 at Northeastern University, College of Charleston, Florida Atlantic University, University of Missouri - St. Louis and Columbia campuses, and Florida International University.

^‡For all outcomes except stages of change, differences are reported as the estimated mean (SE) difference between the Experimental and control groups at post-test (positive sign indicates that the value was greater in the Experimental group). For stages of change, differences are reported as an odds ratio (95% CI) indicating the odds of advancing one or more stages in each Experimental group compared with the control group.

^†The fruit and vegetable and fat intake scale measures were not available at post-test.
