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).
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.
USA in 2008-2009.
Sixty child-care providers participating in CACFP in King County, Washington State.
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).
The results indicate that improving the nutritional quality of foods in child care may require higher food spending.
儿童保育员在促进儿童营养方面发挥着关键作用,但营养食品成本较高可能会造成障碍。本研究检验了这样一个假设,即儿童保育机构提供的食品营养质量越高,其在儿童和成人保健食品计划(CACFP)中支出的食品费用就越高。
在这项横断面研究中,根据 5 天的菜单和食品购买收据,分析了提供给儿童的食品营养质量和食品支出。营养质量基于全谷物、新鲜全水果和蔬菜的份量、能量密度(kJ/g)和七种儿童健康相关营养素的平均营养充足率(膳食参考摄入量的平均百分比)。通过将收据和菜单数据联系起来,计算食品支出。使用双变量统计和多元线性回归模型来检验食品支出与菜单质量之间的关联。
2008-2009 年,美国华盛顿州金县的儿童保育员参加了 CACFP。
60 名参加华盛顿州金县儿童和成人保健食品计划的儿童保育员。
在双变量分析中,每日食品支出越高,总食品能量越高,菜单的营养质量越高。在控制能量和其他协变量后,较高的食品支出与提供的全谷物和新鲜农产品份量呈强烈正相关(P=0.001 和 0.005),与能量密度呈负相关,与菜单整体平均营养素充足率呈正相关(P=0.003 和 0.032)。
结果表明,要提高儿童保育食品的营养质量,可能需要增加食品支出。
