Continued on page S105 Objective: To assess the impact of the Eat Smart, Live Strong (ESLS) intervention on low-income older adults' fruit and vegetable consumption through two independent evaluations. Study Design, Setting, Participants, and Intervention: The ESLS intervention developed by USDA includes four lessons (45-minutes of nutrition education and 20 minutes of physical activity) that were delivered at senior centers and supplemented with take-home materials between March and July 2012. Both evaluations used a quasi-experimental research design to assess program impacts among Supplemental Nutrition Assistance Program (SNAP)-eligible older adults living in Michigan. A total of 34 senior centers and 614 adults aged 60 and older participated in the evaluations. Outcome,Measures andAnalysis: The primary impact measure was increase in participants' average daily intake of fruit and vegetables measured using food frequencies (Evaluation 1) and 24-hour dietary recalls (Evaluation 2). Difference-in-difference models were used to estimate program impact, comparing change across time (baseline and follow-up) in the intervention group with change across time in the comparison group. Results: Evaluation 1: Increased participants' average daily consumption of fruit by 0.2 cups (p < 0.05) and vegetables by 0.31 cups (p< 0.01). Evaluation 2: Increased participants' average daily consumption of fruit by 0.35 cups (p < 0.05) and vegetables by 0.37 cups (p < 0.05). Results from participant surveys and instructor interviews suggest that participants were highly satisfied with the program. Conclusions and Implications: ESLS is an effective curriculum for helping SNAP-eligible older adults eat healthier and should be broadly implemented. Funding: USDA

Conclusions and Implications: This exploratory process evaluation has been instrumental in determining the main barriers and facilitators associated with delivering ‘Smarter Lunchroom Makeovers’. Moving forward, these findings will help inform study design, and have implications for quality of delivery and maintenance of the intervention. They may provide useful insight for others designing interventions, especially in school lunchrooms. Funding: USDA.
