Early care and education (ECE) teachers play an important role in childhood obesity prevention in their classrooms. Online trainings are a convenient and easily accessible means of promoting nutrition education to teachers. The central hypothesis of this study was that an online training for ECE teachers enrolled in the Healthy Child Care Georgia (HCCG) intervention would be an effective means of training as compared to the face-to-face HCCG training. The specific aims of this study were to: 1) Determine the feasibility of an online nutrition education training for ECE teachers; and 2) Determine the effectiveness of the online training when compared to the face-to-face training indicated by changes in knowledge and intentions to provide nutrition education in the classroom. Generally, both groups had comparable changes in knowledge and intentions to change wellness best practices. The feasibility survey also indicated that participants found the online training to be satisfactory and acceptable.
