Children's food intakes do not meet dietary recommendations. Meals offered through the National School Lunch Program and School Breakfast Program make substantial contributions to school-aged children's diets.
This article describes foods offered in school meals and consumed by children at lunch and breakfast, and differences in foods consumed by children who did and did not participate in the school meal programs.
Data were collected as part of the third School Nutrition Dietary Assessment Study, a cross-sectional, nationally representative study conducted in 2005. School menu surveys were used to identify the foods offered in school meals, and 24-hour dietary recalls were used to assess the foods children consumed.
SUBJECTS/SETTING: Foodservice managers in 398 public schools and 2,314 children (grades 1 to 12) from 287 of these schools participated in the study.
Descriptive tabulations report percentages of daily menus that offered and percentages of children that consumed specific food groups and foods at lunch and breakfast. Two-tailed t tests were used to assess differences between school meal program participants and nonparticipants.
Most school menus offered nonfat or 1% milk, fruit or 100% juice, and vegetables daily. Starchy vegetables were more common than dark green/orange vegetables or legumes. School lunch participants were significantly more likely than nonparticipants to consume milk, fruit, and vegetables, and significantly less likely to consume desserts, snack items, and beverages other than milk or 100% juice. At breakfast, participants were significantly more likely than nonparticipants to consume milk and fruit (mainly 100% juice), and significantly less likely to consume beverages other than milk or 100% juice.
Consumption of school meals is positively related to children's intakes of key food groups at lunch and breakfast. Offering more fresh fruit, whole grains, and a greater variety of vegetables could lead to additional health benefits.
儿童的食物摄入量未达到膳食建议标准。通过国家学校午餐计划和学校早餐计划提供的餐食对学龄儿童的饮食有重大贡献。
本文描述了学校午餐和早餐提供的食物以及儿童所食用的食物,以及参与和未参与学校餐食计划的儿童所食用食物的差异。
数据收集于2005年进行的第三次学校营养膳食评估研究,这是一项具有全国代表性的横断面研究。学校菜单调查用于确定学校餐食中提供的食物,24小时膳食回顾用于评估儿童食用的食物。
对象/场所:398所公立学校的食品服务经理以及其中287所学校的2314名儿童(1至12年级)参与了该研究。
描述性表格报告了每日菜单中提供特定食物组和食物的百分比,以及儿童在午餐和早餐时食用这些食物的百分比。双尾t检验用于评估学校餐食计划参与者和非参与者之间的差异。
大多数学校菜单每天提供脱脂或1%的牛奶、水果或100%的果汁以及蔬菜。淀粉类蔬菜比深绿色/橙色蔬菜或豆类更常见。学校午餐参与者比非参与者更有可能食用牛奶、水果和蔬菜,而食用甜点、零食和除牛奶或100%果汁以外的饮料的可能性显著更低。在早餐时,参与者比非参与者更有可能食用牛奶和水果(主要是100%的果汁),而食用除牛奶或100%果汁以外的饮料的可能性显著更低。
学校餐食的消费与儿童在午餐和早餐时关键食物组的摄入量呈正相关。提供更多的新鲜水果、全谷物和更多种类的蔬菜可能会带来更多健康益处。
