先前的研究表明，参与美国国家学校午餐计划（NSLP）与总体上消费更高质量的午餐和饮食有关，但对收入和种族/民族的差异知之甚少。这项分析使用了24小时的饮食回忆数据从学校营养和膳食成本研究，研究如何NSLP参与影响不同收入和种族/民族亚组的学生的饮食质量。使用健康饮食指数（HEI）-2010评估午餐和24小时以上的饮食质量，得分越高表示摄入质量越高。估计每个亚组中NSLP参与者和非参与者的HEI-2010评分，并进行双尾t检验以确定每个亚组中参与者-非参与者评分的差异是否具有统计学意义。对于低收入、高收入、非西班牙裔白色和非西班牙裔黑人学生，NSLP参与者的午餐获得的HEI-2010总分显著高于非参与者，这表明参与NSLP有助于大多数学生食用更健康的午餐。高收入学生和非西班牙裔白色学生的午餐摄入量的这些显着较高的总分持续超过24小时，但不为低收入学生或其他种族/民族的学生。对于所有亚组的NSLP参与者，他们24小时摄入的营养质量远低于午餐，这表明NSLP对他们整体饮食质量的积极影响受到一天中其余时间（午餐以外）消耗的食物的负面影响。
Prior research has shown that participation in the United States’ National School Lunch Program (NSLP) is associated with consuming higher-quality lunches and diets overall, but little is known about differences by income and race/ethnicity. This analysis used 24 h dietary recall data from the School Nutrition and Meal Cost Study to examine how NSLP participation affects the diet quality of students in different income and racial/ethnic subgroups. Diet quality at lunch and over 24 h was assessed using the Healthy Eating Index (HEI)-2010, where higher scores indicate higher-quality intakes. HEI-2010 scores for NSLP participants and nonparticipants in each subgroup were estimated, and two-tailed t-tests were conducted to determine whether participant–nonparticipant differences in scores within each subgroup were statistically significant. NSLP participants’ lunches received significantly higher total HEI-2010 scores than those of nonparticipants for lower-income, higher-income, non-Hispanic White, and non-Hispanic Black students, suggesting that participating in the NSLP helps most students consume healthier lunches. These significantly higher total scores for participants’ lunch intakes persisted over 24 h for higher-income students and non-Hispanic White students but not for lower-income students or students of other races/ethnicities. For NSLP participants in all subgroups, the nutritional quality of their 24 h intakes was much lower than at lunch, suggesting that the positive influence of the NSLP on their overall diet quality was negatively influenced by foods consumed the rest of the day (outside of lunch).
