Nutrition education in the Supplemental Nutrition Assistance Program Education (SNAP-Ed) is designed to promote healthy eating behaviors in a low-income target population.
To evaluate the effectiveness of six SNAP-Ed interventions delivered in child care centers or elementary school settings in increasing participating children's at-home fruit and vegetable (F/V) consumption by 0.3 cups per day and use of fat-free or low-fat milk instead of whole or reduced-fat milk during the prior week.
Clustered randomized or quasi-experimental clustered trials took place in child care centers or elementary schools between 2010 and 2012. Parents of children at intervention and control sites completed baseline and follow-up surveys about their child's at home F/V consumption and other dietary behaviors.
One of the six interventions was successful in meeting the objective of increasing children's F/V consumption by 0.3 cups per day. For three of the six interventions, there was a small but statistically significant increase in F/V consumption and/or use of low-fat or fat-free milk.
Although not all interventions were effective, these findings suggest that it is possible for some SNAP-Ed interventions to improve dietary habits among low-income children among some families. The effective interventions appear to have benefited from implementation experience and sustained efforts at intervention refinement and improvement.
补充营养援助计划教育（SNAP-Ed）中的营养教育旨在促进低收入目标人群的健康饮食行为。
评估在儿童保育中心或小学环境中实施的六项SNAP-Ed干预措施的有效性，即在之前一周内，使参与的儿童每天在家中增加0.3杯水果和蔬菜（F/V）的摄入量，并使用脱脂或低脂牛奶替代全脂或减脂牛奶。
2010年至2012年期间，在儿童保育中心或小学进行了整群随机或准实验性整群试验。干预组和对照组儿童的家长完成了关于其孩子在家中F/V摄入量及其他饮食行为的基线和随访调查。
六项干预措施中有一项成功实现了每天增加儿童F/V摄入量0.3杯的目标。六项干预措施中有三项在F/V摄入量和/或低脂或脱脂牛奶的使用方面有小幅但具有统计学意义的增加。
虽然并非所有干预措施都有效，但这些研究结果表明，一些SNAP-Ed干预措施有可能改善部分低收入家庭儿童的饮食习惯。有效的干预措施似乎受益于实施经验以及在干预措施优化和改进方面的持续努力。
