2009年,妇女、婴儿和儿童(women,infants,and children,WIC)特殊附加营养计划对WIC食品包装实施修正(拟发表于2014年4月Journal of the Academy of Nutrition and Dietetics)。计划削减了牛奶和奶酪津贴,年龄超过23个月的民众不允许食用全脂牛奶。从一个新英格兰连锁超市使用前瞻性研究设计和扫描WIC家庭的购买数据,本实验评估了新WIC包装在康涅狄格州和马萨诸塞州地区如何影响牛奶和奶酪购买并在WIC家庭中饱和脂肪的摄入量。在WIC修正案之前和之后(2009—2010)康涅狄格州515个WIC家庭的牛奶和奶酪购买量使用广义估计方程模型进行较。在康涅狄格州使用新的WIC包装后,WIC购买牛奶中,全脂奶份额从60%下降到25%,但在非WIC购买资金上持平(50%)。牛奶总量下降了14.2%(P<0.001),全脂牛奶下降了一半(P<0.001),符合WIC条件的奶酪下降了37.2%(P<0.001)。限制全脂牛奶后,WIC购买力在康涅狄格州转向减脂牛奶,
In 2009, WIFS supplements (to be published in the April 2014 Journal of the Academy of Nutrition and Dietetics) were supplemented by special supplemental nutrition programs for women, infants, and children (WIC). Plans to cut milk and cheese allowances, people over the age of 23 months are not allowed to eat whole milk. Using a prospective study from a New England supermarket to design and scan purchase data for WIC households, this experiment assesses how the new WIC package affects the purchase of milk and cheese and the saturated fat intake in WIC households in Connecticut and Massachusetts . The purchases of milk and cheese from 515 WIC families in Connecticut before and after the WIC Amendments (2009-2010) were compared using a generalized estimating equation model. After using the new WIC package in Connecticut, WIC’s share of total milk decreased from 60% to 25%, but was flat (50%) for non-WIC purchases. Total milk decreased by 14.2% (P <0.001), whole milk decreased by half (P <0.001), and cheese with WIC decreased by 37.2% (P <0.001). After limiting full-fat milk, WIC’s purchasing power shifted to reduced-fat milk in Connecticut,
