目的：为了量化先声夺人（HS）教师对健康政策干预效果的中介和调节影响。设计：在一个较大的随机社区试验中进行干预试验。设置：夏威夷的HS幼儿园。参与者：位于2个先前随机社区内的23个HS教室。干预：为期7个月的多成分干预，包括食品供应和服务风格的政策变化，员工健康倡议，学龄前儿童的课堂活动，促进体育活动（PA）和健康饮食，以及培训和技术援助。环境与政策评估和观察（EPAO）课堂分数和教师问卷调查，评估知识，信念，优先事项，分析：采用配对t检验和线性回归分析，检验了教师变量对课堂环境的干预效果以及教师变量对课堂环境的中介和调节作用。一般线性模型检验显示，当教师报告其自身健康状况和行为的改善高于平均水平时，干预对EPAO评分的影响更大（估计值[SE] = -2.47（0.78），P
Objective: To quantify the Head Start (HS) teacher mediating and moderating influence on the effect of a wellness policy intervention.Design: Intervention trial within a larger randomized community trial.Setting: HS preschools in Hawaii.Participants: Twenty-three HS classrooms located within 2 previously randomized communities.Intervention: Seven-month multi-component intervention with policy changes to food served and service style, initiatives for employee wellness, classroom activities for preschoolers promoting physical activity (PA) and healthy eating, and training and technical assistance.Main Outcome Measures: The Environment and Policy Assessment and Observation (EPAO) classroom scores and teacher questionnaires assessing on knowledge, beliefs, priorities, and misconceptions around child nutrition and changes in personal health behaviors and status were the main outcome measures.Analysis: Paired t tests and linear regression analysis tested the intervention effects on the classroom and mediating and moderating effects of the teacher variables on the classroom environment.Results: General linearmodel test showed greater intervention effect on the EPAO score where teachers reported higher than average improvements in their own health status and behaviors (estimate [SE] = -2.47 (0.78), P
