背景：2009年，美国农业部妇女、婴儿和儿童特殊补充营养计划（WIC）对WIC提供的食品的成分和数量进行了修订。新的全谷物产品，如全麦面包和允许的替代品被添加，以鼓励WIC参与者增加全谷物和纤维的摄入量。目的：本文评估WIC修订如何影响康涅狄格州和马萨诸塞州WIC参与家庭的面包和大米购买。方法：使用区域连锁超市的扫描仪数据对2137户WIC家庭的面包和大米购买情况进行检查。使用广义估计方程模型比较了WIC修订版实施前后（2009-2010年）面包和大米的购买量。数据于2013年进行分析。结果：在WIC修订之前，当WIC不提供面包或大米时，WIC家庭购买的面包主要是白面包（占总量的78%），几乎所有购买的大米都是白面包（94%）。由于WIC的修订，100%全麦面包在面包总购买量中的份额增加了两倍（从8%增加到24%），取代了白面包的购买量；糙米在大米采购中的份额上升到30%。WIC家庭利用WIC福利改变了他们购买面包的方式，而不是购买更多的面包，而大米的总购买量却增加了。结论：2009年WIC修订版显著增加了WIC参与家庭的全麦面包和大米购买量。低收入社区全麦和纤维摄入量的增加可能会对公共健康产生重要影响。(C) 2013年美国预防医学杂志
Background: In 2009, the U.S. Department of Agriculture's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) implemented revisions to the composition and quantities of WIC-provided foods. New whole-grain products such as whole-wheat bread and allowable substitutes were added to encourage increased intake of whole grains and fiber among WIC participants.Purpose: This paper assesses how the WIC revisions affected purchases of bread and rice among WIC-participating households in Connecticut and Massachusetts.Methods: Scanner data from a regional supermarket chain were used to examine bread and rice purchases of 2137 WIC households. Purchased volume of bread and rice was compared before and after implementation of the WIC revisions (2009-2010) using generalized estimating equation models. Data were analyzed in 2013.Results: Before the WIC revisions, when no bread or rice was provided through WIC, white bread dominated bread purchases among WIC households (78% of volume), and almost all rice purchased was white (94%). As a result of the WIC revisions, the share of 100% whole-grain bread in total bread purchases tripled (from 8% to 24%), replacing purchases of white bread; the share of brown rice rose to 30% of rice purchases. WIC households used WIC benefits to change some of their bread purchases, rather than to buy more bread overall, whereas total rice purchases increased.Conclusions: The 2009 WIC revisions significantly increased purchases of whole-grain bread and rice among WIC-participating families. The likely increase in whole-grain and fiber intake among low-income communities could have important public health implications. (C) 2013 American Journal of Preventive Medicine
