Background EAT.RIGHT.NOW. (ERN) is a nutrition education outreach program, available to Supplemental Nutrition Assistance Program (SNAP) eligible students enrolled in The School District of Philadelphia (SDP). ERN is a component of the PA TRACKS initiative, funded by the U.S. Department of Agriculture (USDA) Food and Nutrition Service (FNS), with matching state and local support. Research shows that vegetable consumption has positive effects on children’s health and weight status. 1,2 Low vegetable intake can be attributed to a number of factors that influence behavior, including knowledge, attitude, self-efficacy, and preference. 3,4 Project Overview Vegetable Core (VC) is a fourth grade classroom-based standardized intervention that aims to increase vegetable consumption in children. VC was implemented and evaluated in select SDP schools during the school year (SY). The School District of Philadelphia (SDP) Office of Research and Evaluation (ORE) aimed to investigate changes in student content knowledge and other key VC measures over an extended period of time. Methods During the SY, th grade students participated in the VC evaluation. They completed pre- and post-surveys which included questions regarding VC knowledge, self-efficacy, attitude, and preference measures. In the SY follow-up evaluation, the final sample was reduced to 365 students. Results/Conclusions Results from the SY pre- and post-surveys indicated VC significantly improved students’ knowledge, attitude, self-efficacy, and preference regarding vegetables (see Table 1). Although there was a significant decrease in VC knowledge scores from 4 th grade post-survey to 5 th grade follow-up (see Table 2), the mean score at 5 th grade follow-up was significantly higher than 4 th grade pre-survey scores (see Table 3), indicating that VC knowledge was retained to some extent (see Figure 1). Research to Practice Strategies The VC intervention did not generate persistent long- term positive results. With the absence of the VC lessons, there were significant declines in students’ vegetable attitudes and preferences during the SY. ORE recommends that nutrition education be delivered over longer periods of time with reinforcement lessons or activities in order to help sustain knowledge, self-efficacy, attitude and preference toward vegetable consumption and other healthy eating behaviors.
