Effects of a nutrition education program on the dietary behavior and nutrition knowledge of second-grade and third-grade students.

This research investigated the effects of a nutrition education program on dietary behavior and nutrition knowledge among elementary school-aged children participating in a Social Cognitive Theory-based nutrition education program. Participants included 1100 second-grade and third-grade students selected by convenience-type sampling from public schools in Alabama. A preassessment and postassessment control group design assessed dietary behavior and nutrition knowledge using Pizza Please, a specially designed interactive evaluation tool.
