To compare differences in fruit and vegetable (FV) intake and FV stage of change in 2 diverse communities engaging with cooperative extension services (Extension).
Cross-sectional study of FV behaviors of community members enrolled in a team-based challenge offered by Extension. t test and chi-square analyses examined differences in FV intake and FV stage of change. Linear regression examined the relationship between FV stage of change and FV intake, adjusting for demographics.
There was a significant (P = .01) difference in staging between the African American and Hispanic communities. Of individuals in the African American community, 60% were in the preparation stage; in the Hispanic community, 55% were in the precontemplation/contemplation stage. The FV stage of change was significantly associated with daily FV intake (β = .53; P < .001).
To promote consumption of FVs better, nutrition education programs such as Extension should differentiate based on stages of change among subpopulations.
比较参与合作推广服务（推广）的两个不同社区在水果和蔬菜（FV）摄入量及FV行为改变阶段方面的差异。
对参加推广部门提供的团队挑战的社区成员的FV行为进行横断面研究。t检验和卡方分析用于检验FV摄入量和FV行为改变阶段的差异。线性回归分析用于检验FV行为改变阶段与FV摄入量之间的关系，并对人口统计学因素进行调整。
非裔美国人和西班牙裔社区在阶段划分上存在显著差异（P = 0.01）。在非裔美国社区中，60%的人处于准备阶段；在西班牙裔社区中，55%的人处于未考虑/考虑阶段。FV行为改变阶段与每日FV摄入量显著相关（β = 0.53；P < 0.001）。
为了更好地促进FV的消费，像推广这样的营养教育项目应根据亚人群体的行为改变阶段进行区分。
