Childhood overweight and obesity are major health problems. School-based programs enable intervening with large groups of children, but program overall health impact is rarely completely assessed. A RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) analysis tested the overall public health impact of the fourth-grade "Nutrition Pathfinders" school-based nutrition-education program. A randomized controlled trial in 47 fourth-grade California classrooms (1713 students) tested program efficacy, and a secondary analysis of archival data tested program dissemination. Desired effects were seen in child nutrition knowledge, attitudes, consumption of low-nutrient high-density foods, sugar-sweetened beverages, proteins, grains, and parent willingness to serve new foods. The program was disseminated to ∼25 % of public school fourth-grade classrooms in California and cost about $1.00 per student to implement. The Nutrition Pathfinders program demonstrates potential for moderate to high public health impact due to its wide dissemination, effectiveness in altering attitudes and behaviors, and its relatively inexpensive cost of implementation.
儿童超重和肥胖是主要的健康问题。基于学校的项目能够对大量儿童进行干预，但项目对整体健康的影响很少得到全面评估。一项RE-AIM（覆盖、效果、采用、实施、维持）分析测试了四年级“营养探索者”这一基于学校的营养教育项目对公众健康的整体影响。在加利福尼亚州47个四年级教室（1713名学生）开展的一项随机对照试验测试了项目效果，对存档数据的二次分析测试了项目传播情况。在儿童营养知识、态度、低营养高密度食品消费、含糖饮料、蛋白质、谷物以及家长提供新食物的意愿方面都出现了预期效果。该项目在加利福尼亚州约25%的公立学校四年级教室中得到推广，实施成本约为每名学生1美元。“营养探索者”项目因其广泛传播、在改变态度和行为方面的有效性以及相对低廉的实施成本，显示出对公众健康产生中度至高影响的潜力。
