Childhood obesity is an ongoing public health program. As such, a major public health research objective is to identify potential targets for intervention; one such area is school lunches (SL). The National School Lunch Program (NSLP) serves over 31 million children each day; the National Health and Nutrition Examination Survey (NHANES) is uniquely positioned to allow researchers to assess diet quality in federal nutrition assistance programs. The objective of the study was to investigate whether lunches provided by schools provide different nutritional value than lunches obtained elsewhere. In a nationally representative sample of 2190 children, consumption of a school-provided lunch (SL) was associated with greater nutritional quality compared to lunches obtained elsewhere across both age and income categories. Children who were eligible for no-cost school lunch, but did not participate in the NSLP consumed approximately 60% more energy, 58% more total fat, 60% more saturated fat, 50% more solid fat, 61% more sodium, double the amount of added sugars and less than half the amount of fruit than NSLP participants (all < 0.001). The results of this study suggest that though widely criticized, school lunches provide superior nutrient quality than lunches obtained from other sources, particularly for low-income children.
儿童肥胖是一个持续存在的公共卫生项目。因此,主要的公共卫生研究目标是确定潜在的干预目标;其中一个领域是学校午餐 (SL)。国家学校午餐计划 (NSLP) 每天为超过 3100 万名儿童提供服务;国家健康和营养检查调查 (NHANES) 独特的地位使研究人员能够评估联邦营养援助计划中的饮食质量。该研究的目的是调查学校提供的午餐是否与其他地方获得的午餐在营养价值上有所不同。在一个具有全国代表性的 2190 名儿童样本中,与从其他地方获得的午餐相比,学校提供的午餐 (SL) 的消费与更高的营养质量相关,无论年龄和收入类别如何。有资格获得免费学校午餐但未参加 NSLP 的儿童摄入的能量约多 60%,总脂肪多 58%,饱和脂肪多 60%,固体脂肪多 50%,钠多 61%,添加糖多一倍,水果摄入量不到 NSLP 参与者的一半(所有 < 0.001)。这项研究的结果表明,尽管受到广泛批评,但学校午餐提供的营养质量优于从其他来源获得的午餐,特别是对于低收入儿童。
