In this study, the authors evaluated the effectiveness of the Energize Your Life! social-marketing campaign pilot study to improve knowledge, attitudes, and fruit intake among community college students. The authors used a cross-sectional, quasi-experimental, pre- and posttest design. They randomly selected community college students (N = 1,367) and exposed the intervention campus to fruit fairs to distribute fresh fruit, 100% fruit juice, and fruit smoothie samples and information about fruit to students. The authors also addressed policy change to increase the accessibility of fruit on campus. There was a significant increase in fruit intake between pre- and posttest at the intervention campus. Although students had positive attitudes toward intake, most did not achieve the minimum recommended daily 2 servings of fruit. Approximately 25% of the students had insufficient funds, which affected their food intake. Longer-term social marketing interventions may be an effective means of improving the dietary quality of community college students.
