目的：检查“健康饮食，保持活跃”试点项目的有效性，这是一个多地点，为期6个月的教育干预，旨在促进启智工作人员，家长和儿童的健康营养和身体活动。设计：比较组内干预前和干预后的知识和行为，以及拟人化测量。背景：这项研究是在五个州的六个大型启智机构的方便样本中进行的。对象：参与者包括496名工作人员、438名家长和112名学龄前儿童。干预：为期6个月的干预包括针对工作人员和家长的核心培训和强化活动，这些活动与儿童课程相一致。测量方法：前后问卷调查和人体测量测量检查了与营养和身体活动相关的身体质量指数（BMI）、知识和行为的变化。分析：配对t检验比较干预前和干预后体重和BMI；多重回归分析，检查体重变化和其他协变量之间的关系，包括知识和行为变化，控制社会人口变量。结果：每组参与者均表现出BMI（成人平均为30.1至29.2,p < 0.001；儿童平均为17.0至16.6,p < 0.001）和肥胖儿童（30%至21%，p < 0.001）和成人（45%至40%，p < 0.001）的显著降低。儿童体重变化与父母体重变化相关。结论：该干预措施显示出良好的初步结果，作为一种促进成人和儿童健康行为的干预措施，具有潜在的有效性。
PURPOSE: Examine the effectiveness of the "Eat Healthy, Stay Active!" pilot program, a multisite, 6-month educational intervention to promote healthy nutrition and physical activity among Head Start staff, parents, and children.DESIGN: Comparison of within-group preintervention and postintervention knowledge and behavior, along with anthropomorphic measurements.SETTING: The study was conducted in a convenience sample of six large Head Start agencies in five states.SUBJECTS: Participants included 496 staff, 438 parents, and 112 preschool children.INTERVENTION: The 6-month intervention consisted of core trainings and reinforcing activities for staff and parents that aligned with children's curricula.MEASURES: Pre-post questionnaires and anthropometric measurements examined changes in body mass index (BMI), knowledge, and behaviors related to nutrition and physical activity.ANALYSIS: Paired t-tests to compare preintervention and postintervention weights and BMI; multiple regression analyses to examine associations between weight changes and other covariates, including knowledge and behavior changes, controlling for sociodemographic variables.RESULTS: Each group of participants demonstrated significant reductions in BMI (mean = 30.1 to 29.2; p < .001 in adults and 17.0 to 16.6; p < 0.001 in children) and in the proportion of obese children (30% to 21%; p < .001) and adults (45% to 40%; p < .001). Child weight changes correlated with parent weight changes.CONCLUSION: This intervention showed promising initial results, with potential effectiveness as an intervention to promote healthier behaviors among adults and children in Head Start settings.
