Finally, HOP’N was a public health effectiveness trial that had limited direct investigator team contact and economic input into the community. The Georgia FitKid intervention included aspects of an efficacy trial, such that the team was involved in program delivery on site. Children were also eliminated from the analysis due to poor attendance, the program was free of charge, and the healthful snack, transportation, and staff received partial or total support from project funds. The after-school setting can be enhanced to facilitate obesity prevention; however, the challenge is in reaching children and motivating them to attend after-school programs regularly. Unlike efficacy models, our training model provides a method for program improvement that can be easily disseminated to improve the quality of existing after-school programs in community settings without considerable onsite face-to-face involvement by experts and without an investment in additional after-school staff.

N2 - Background: This paper reports the primary outcomes of the Healthy Opportunities for Physical Activity and Nutrition (HOP'N) after-school project, which was an effectiveness trial designed to evaluate the prevention of childhood obesity through building the capacity of after-school staff to increase physical activity (PA) and fruit and vegetable (FV) opportunities.Methods: We conducted a three-year, nested cross-sectional group randomized controlled effectiveness trial. After a baseline assessment year (2005-2006), schools and their after-school programs were randomized to the HOP'N after-school program (n = 4) or control (n = 3), and assessed for two subsequent years (intervention year 1, 2006-2007; intervention year 2, 2007-2008). Across the three years, 715 fourth grade students, and 246 third and fourth grade after-school program participants were included in the study. HOP'N included community government human service agency (Cooperative Extension) led community development efforts, a three-time yearly training of after-school staff, daily PA for 30 minutes following CATCH guidelines, a daily healthful snack, and a weekly nutrition and PA curriculum (HOP'N Club). Child outcomes included change in age- and gender-specific body mass index z-scores (BMIz) across the school year and PA during after-school time measured by accelerometers. The success of HOP'N in changing after-school program opportunities was evaluated by observations over the school year of after-school program physical activity sessions and snack FV offerings. Data were analyzed in 2009.Results: The intervention had no impact on changes in BMIz. Overweight/obese children attending HOP'N after-school programs performed 5.92 minutes more moderate-to-vigorous PA per day after intervention, which eliminated a baseline year deficit of 9.65 minutes per day (p < 0.05) compared to control site overweight/obese children. Active recreation program time at HOP'N sites was 23.40 minutes (intervention year 1, p = 0.01) and 14.20 minutes (intervention year 2, p = 0.10) greater than control sites. HOP'N sites and control sites did not differ in the number of FV offered as snacks.Conclusions: The HOP'N program had a positive impact on overweight/obese children's PA and after-school active recreation time.Trial registration: NCT01015599.
