背景和目的：2009年10月，修订了妇女、婴儿和儿童特别补充营养计划（WIC）食品包装，增加了水果、蔬菜、全谷物和低脂牛奶。我们检验了WIC食品包装修订对使用WIC的家庭中儿童饮食质量的影响。方法：采用2003-2008年和2011-2012年《全国健康与营养检查调查》，对政策实施前后1197名低收入家庭2 ~ 4岁儿童进行研究。健康饮食指数-2010 （HEI-2010）是通过两次24小时饮食回顾来计算的。使用线性回归来检验HEI-2010得分的差异，该差异可归因于食品包装的变化，调整了WIC参与者和非参与者之间的基线和长期趋势，以及儿童和家庭特征。采用广义线性模型对HEI-2010指数的各成分得分进行分析。结果：参与者和非参与者的平均HEI-2010得分在基线时分别为52.4和50.0，政策改变后分别为58.3和52.4。与非参与者相比，WIC食品包装修订与WIC参与者的HEI-2010调整平均增加3.7分（95%置信区间，0.6-6.9）相关。特别是，与非参与者相比，WIC参与者的绿色和豆类成分得分相对增加了3.4倍（95%置信区间，1.3-9.4）。结论：来自这个国家样本的结果表明，WIC食品包装的修订与参加WIC的儿童更高的饮食质量有关。
BACKGROUND AND OBJECTIVES: In October 2009, the Special Supplemental Nutrition Program for Women, Infant, and Children (WIC) food package was revised to include more fruits, vegetables, whole grains, and lower-fat milk. We examined the impact of the WIC food package revisions on the diet quality of children in households using WIC.METHODS: A total of 1197 children aged 2 to 4 years from low-income households were studied from before and after the policy implementation (using the 2003-2008 and 2011-2012 National Health and Nutrition Examination Survey). The Healthy Eating Index-2010 (HEI-2010) was calculated using two 24-hour diet recalls. Linear regression was used to examine the difference in HEI-2010 score attributable to the food package change, adjusting for baseline and secular trends among WIC participants and nonparticipants, as well as child and household characteristics. Component scores of the HEI-2010 index were analyzed with generalized linear models.RESULTS: Average HEI-2010 scores for participants and nonparticipants were 52.4 and 50.0 at baseline, and 58.3 and 52.4 after the policy change, respectively. The WIC food package revisions were associated with an adjusted average of 3.7 additional HEI-2010 points (95% confidence interval, 0.6-6.9) for WIC participants compared with nonparticipants. In particular, the revisions were associated with a 3.4-fold relative increase (95% confidence interval, 1.3-9.4) in the Greens and Beans component score for WIC participants compared with nonparticipants.CONCLUSIONS: Results from this national sample indicate that the WIC food package revisions were associated with higher diet quality for children participating in WIC.
