BACKGROUND Sweet drinks early in life could predispose to lifelong consumption, and the beverage industry does not clearly define fruit drinks as part of the sweet drink category. OBJECTIVES To ascertain the relationship between beverage selection and dietary quality of the lunches packed for preschool-aged children evaluated using the Healthy Eating Index-2010. METHODS Foods packed by parents (n=607) were observed at 30 early care and education centers on two nonconsecutive days. Three-level regression models were used to examine the dietary quality of lunches by beverage selection and the dietary quality of the lunch controlling for the nutrient composition of the beverage by removing it from the analysis. RESULTS Fruit drinks were included in 25% of parent-packed lunches, followed by 100% fruit juice (14%), milk (14%), and flavored milk (3.7%). Lunches with plain milk had the highest Healthy Eating Index-2010 scores (59.3) followed by lunches with 100% fruit juice (56.9) and flavored milk (53.2). Lunches with fruit drinks had the lowest Healthy Eating Index-2010 scores at 48.6. After excluding the nutrient content of the beverage, the significant difference between lunches containing milk and flavored milk persisted (+5.5), whereas the difference between fruit drinks and 100% fruit juice did not. CONCLUSIONS Dietary quality is associated with the type of beverage packed and these differences hold when the lunch is analyzed without the nutrient content of the beverage included.

饮料选择对学龄前儿童盒装午餐膳食质量的贡献

背景技术在生命早期的甜饮料可能倾向于终生消费，并且饮料行业并没有明确将水果饮料定义为甜饮料类别的一部分。目的 确定饮料选择与使用健康饮食指数 2010 评估的学龄前儿童午餐的膳食质量之间的关系。方法 在非连续的两天内，在 30 个早期护理和教育中心观察了由父母 (n=607) 包装的食物。使用三级回归模型通过饮料选择来检查午餐的膳食质量，并通过将其从分析中删除来控制饮料的营养成分的午餐膳食质量。结果 25% 的家长打包午餐包括果汁饮料，其次是 100% 果汁 (14%)、牛奶 (14%) 和调味牛奶 (3.7%)。纯牛奶午餐的健康饮食指数 2010 得分最高 (59.3)，其次是 100% 果汁午餐 (56.9) 和调味牛奶 (53.2)。带水果饮料的午餐的健康饮食指数 2010 得分最低，为 48.6。在排除饮料的营养成分后，含牛奶和调味牛奶的午餐之间的显着差异仍然存在（+5.5），而水果饮料和 100% 果汁之间的差异则没有。结论 膳食质量与包装的饮料类型有关，当分析午餐时不包括饮料的营养成分时，这些差异仍然存在。带水果饮料的午餐的健康饮食指数 2010 得分最低，为 48.6。在排除饮料的营养成分后，含牛奶和调味牛奶的午餐之间的显着差异仍然存在（+5.5），而水果饮料和 100% 果汁之间的差异则没有。结论 膳食质量与包装的饮料类型有关，当分析午餐时不包括饮料的营养成分时，这些差异仍然存在。含水果饮料的午餐的健康饮食指数 2010 得分最低，为 48.6。在排除饮料的营养成分后，含牛奶和调味牛奶的午餐之间的显着差异仍然存在（+5.5），而水果饮料和 100% 果汁之间的差异则没有。结论 膳食质量与包装的饮料类型有关，当分析午餐时不包括饮料的营养成分时，这些差异仍然存在。
