Objective: NutriBee was the first clinical nutrition intervention designed to bring the Institute of Medicine recommendations for 20 hours of experiential nutrition-themed learning to grades 4–7 into club and camp settings. We piloted NutriBee to assess acceptability and impact among early adolescents in diverse and disadvantaged communities in order to evaluate its future potential as a group medical nutrition intervention.Methods: Nine communities across Guam, Maryland, Michigan, and New Mexico representing South Pacific Island, American Indian, urban African American, recently immigrated Hispanic, and rural Caucasian ethnic groups piloted NutriBee in nonclinical settings (clubs, schools, camps). The 6 club and camp pilots administered consenting NutriBee participants a 41-question pre–post survey assessing impact on food selection and the psychosocial parameters of intentions, outcome expectations, self-efficacy, and knowledge. Process measures included dose, fidelity, and acceptability questions.Results: Pre- and postsurveys were completed by 170 of 179 (95%) consenting, eligible participants. Impact scores increased significantly (p < 0.001): Food selection behavior (+9.3%), intentions (+19.1%), outcome expectations (+15.1%), self-efficacy (+7.4%), and knowledge (+17.6%). Each pilot (n = 6) demonstrated significant (p < 0.001) impact, a mean dose delivered of 80% (16 hours) or higher, and an acceptability score of at least 74%. Girls participating in girl-only programs (n = 72) shared greater impact than girls in coed programs (n = 41; 13.6% vs. 10.4% mean score increase, p = 0.05).Conclusions: NutriBee successfully extended the impact of an IOM-aligned intervention to club and camp settings to which clinicians can refer at-risk early adolescents.
