Long-term Student Outcomes of the Integrated Nutrition and Physical Activity Program.

Objective: To examine the long-term effects of the Integrated Nutrition and Physical Activity Program (INPAP), a school-based nutrition education program. Design: Quasi-experimental design comparing intervention and comparison cohorts at 3-6 years after delivery of the INPAP intervention on nutrition- and physical activity-related outcomes. Setting: This study was conducted in 1 school district in a low-income rural county of ~15,000 residents in south-central Colorado. Participants: In second grade, intervention and comparison cohorts included 173 (fall 2000) and 190 (fall 1999) students, respectively. Approximately 60% of these students completed assessments in eighth grade. Interventions: INPAP is an experiential school-based nutrition education program, grounded in social cognitive theory and Piaget's cognitive development theory and adapted for use in a rural setting. Outcomes: Nutrition and physical activity knowledge, self-efficacy, attitudes and behaviors, body mass index. Analysis: Wilcoxon signed rank test, chi-square test for proportions, and t test for means. Results: Long-term effects were observed in nutrition-related knowledge and attitudes but not self-efficacy or behavior change. The effects that did occur were attenuated over time. Conclusion and Implications: This study found that INPAP implemented in elementary school had limited lasting effects by the end of middle school, a time when students have increased autonomy to make food choices.
