Background: The obesity epidemic and associated chronic conditions pressure the importance of nutrition education, and showcase a need for collaborative efforts. The evaluation and documentation of nutrition education is essential to improve impacts and outcomes of efforts.

Methods: Three interventions are described within this thesis. The first reviews traditional nutrition education provided by Extension, and the need for objective evaluation measures. The second project compares traditional and technology-based education modes in the grocery store setting. The third project is a technology-based iPhone application and mobile website developed for the Iowa State Fair to provide just-in-time nutrition information on the available fare.

Results: The objective evaluation measure implemented was successful for documentation of effectiveness of Extension education efforts, and improved dietary intake of participants. The second project found equivalent awareness of intervention materials. However, significantly higher engagement occurred with the traditional education mode when compared with the technology-based efforts. The third project was a success at the Iowa State Fair, with many page views for both vendor, foods, and nutrition information.

Conclusions: Nutrition education efforts provide the most impact when strategic, with collaborative efforts achieving greater reach. Education efforts appear to be additive in nature with regard to impact, thus increased promotional activities and interactions are most likely to find engagement and subsequent behavior change.
