Healthy lifestyles education (HLE) is defined as nutrition and physical activity education aimed at controlling or preventing serious health issues. The purpose of the study reported here was to determine knowledge and behaviors of Extension Family and Consumer Sciences (FACS) and 4-H agents concerning HLE. Eighty-five and 86% of FACS and 4-H agents, respectively, were likely to address HLE if high-quality curriculum/materials were available. Barriers related to implementing HLE were: communicating with parents; parents' lack of interest; and lack of curriculum resources. All agents, regardless of programming responsibility, should model healthy lifestyles behaviors to be effective change agents.
