The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides monthly food packages to low-income children (aged 1-4 years) in the U.S., including 128 ounces of 100% fruit juice and an $8 cash value voucher for purchasing fruits and vegetables. The fruit juice allowance translates to 71%-107% of the maximum intake recommended by the American Academy of Pediatrics (4-6 ounces/day). Careful examination of WIC food package allocations is necessary because overconsumption of fruit juice among young children has been linked to weight gain and juice lacks important nutrients found in whole fruit (e.g., fiber).
A total of 1,576 children aged 2-4 years were assessed using the 2009-2014 National Health and Nutrition Examination Surveys. Multiple linear regressions were conducted in 2017 to analyze the association between WIC program participation and intake of 100% fruit juice, whole fruits, and vegetables. Logistic regression was used to examine the association between WIC program participation and the odds of exceeding the American Academy of Pediatrics maximum intake for juice.
Adjusting for child and parent/caregiver characteristics, WIC participants consumed significantly more 100% fruit juice (β=0.22 cup equivalents/day, 95% CI=0.04, 0.40) compared with income-eligible nonparticipants, but not more whole fruits or total vegetables. WIC participants had 1.51-times greater odds (95% CI=1.06, 2.14) of exceeding the age-specific American Academy of Pediatrics maximum intake for juice compared with income-eligible nonparticipants.
These findings support recommendations to reduce 100% fruit juice allowances in the WIC program and reallocate those funds to the cash value voucher to increase whole fruit and vegetable consumption.
妇女、婴儿和儿童特别补充营养计划(WIC)为美国低收入儿童(1-4 岁)提供每月食品包,其中包括 128 盎司 100%纯果汁和 8 美元现金券,用于购买水果和蔬菜。果汁津贴相当于美国儿科学会(AAP)推荐的最大摄入量的 71%-107%(4-6 盎司/天)。仔细检查 WIC 食品包分配情况是必要的,因为幼儿过量饮用果汁与体重增加有关,而且果汁缺乏完整水果中所含的重要营养物质(例如纤维)。
利用 2009-2014 年全国健康和营养调查,对 1576 名 2-4 岁儿童进行评估。2017 年进行了多项线性回归分析,以研究 WIC 计划参与情况与 100%纯果汁、全水果和蔬菜摄入量之间的关系。使用逻辑回归分析 WIC 计划参与情况与超过 AAP 果汁最大摄入量的可能性之间的关系。
调整儿童和家长/照顾者特征后,与符合收入条件的非参与者相比,WIC 参与者饮用的 100%纯果汁显著更多(β=0.22 杯当量/天,95%置信区间=0.04,0.40),但全水果或总蔬菜摄入量并未更多。与符合收入条件的非参与者相比,WIC 参与者超过特定年龄 AAP 果汁最大摄入量的可能性高出 1.51 倍(95%置信区间=1.06,2.14)。
这些发现支持减少 WIC 计划中 100%纯果汁津贴并将这些资金重新分配给现金券以增加全水果和蔬菜消费的建议。
