目标：儿童保育提供者在促进儿童营养方面可以发挥关键作用，但营养食品的较高成本可能会构成障碍。本研究检验了以下假设：参与儿童和成人护理食品计划 (CACFP) 的儿童保育院所提供的食品的营养质量越高，食品支出越高。 设计：在这项横断面研究中，根据 5 天的菜单和食品购物收据分析了向儿童提供的食品的营养质量和食品支出。营养质量基于全谷物、新鲜水果和蔬菜的份量、能量密度（千焦/克）以及与儿童健康有关的七种营养素的平均营养充足度（膳食参考摄入量的平均百分比）。食品支出是通过将收据和菜单数据联系起来计算的。使用双变量统计数据和多元线性回归模型检查食品支出和菜单质量之间的关联。背景：2008-2009 年美国。受试者：华盛顿州金县参与 CACFP 的 60 名儿童保育提供者。结果：在双变量分析中，较高的每日食品支出与较高的总食物能量和较高的菜单营养质量相关。在控制能量和其他协变量的情况下，较高的食品支出与全谷物和新鲜农产品的份数呈强烈正相关（分别为 P = 0.001 和 0.005），能量密度较低，总体菜单的平均营养充足度较高（分别为 P = 0.003 和 0.032）。结论：结果表明，提高儿童保育食品的营养质量可能需要更高的食品支出。
Objective: Child-care providers have a key role to play in promoting child nutrition, but the higher cost of nutritious foods may pose a barrier. The present study tested the hypothesis that higher nutritional quality of foods served was associated with higher food expenditures in child care homes participating in the Child and Adult Care Food Program (CACFP).Design: In this cross-sectional study, nutritional quality of foods served to children and food expenditures were analysed based on 5 d menus and food shopping receipts. Nutritional quality was based on servings of whole grains, fresh whole fruits and vegetables, energy density (kJ/g) and mean nutrient adequacy (mean percentage of dietary reference intake) for seven nutrients of concern for child health. Food expenditures were calculated by linking receipt and menu data. Associations between food expenditures and menu quality were examined using bivariate statistics and multiple linear regression models.Setting: USA in 2008-2009.Subjects: Sixty child-care providers participating in CACFP in King County, Washington State.Results: In bivariate analyses, higher daily food expenditures were associated with higher total food energy and higher nutritional quality of menus. Controlling for energy and other covariates, higher food expenditures were strongly and positively associated with number of portions of whole grains and fresh produce served (P = 0.001 and 0.005, respectively), with lower energy density and with higher mean nutrient adequacy of menus overall (P = 0.003 and 0.032, respectively).Conclusions: The results indicate that improving the nutritional quality of foods in child care may require higher food spending.
