Children in the United States exhibit high rates of nutrient inadequacy and overweight/obesity; other international studies report similar associations. The School Breakfast Program (SBP) may help alleviate these conditions for youth in the United States. This research examined the association of ready-to-eat (RTE) breakfast cereal consumption with students' (SBP participants and nonparticipants) dietary nutrient intake and weight status.
Data were from the third School Nutrition Dietary Assessment Study (SNDA-III), conducted in 2004-2005. Analyses included all 2298 SNDA-III participants (ages 5-18 years), who completed a dietary recall and whose parents completed an interview. Students were categorized as skipping versus eating breakfast; students eating breakfast were categorized by SBP participation (SBP participant vs nonparticipant) and breakfast type (with vs without RTE cereal). Analyses estimated the association of these categorizations with total daily nutrient intake and weight-related measures, after adjusting for covariates.
RTE cereal breakfast consumers (regardless of SBP participation) had greater intake of vitamin A, iron, and whole grain, compared with noncereal breakfast eaters. Breakfast consumers (regardless of SBP participation and type) had greater intake of vitamins A and C, calcium, iron, dietary fiber, and whole grain, relative to breakfast skippers.
The SBP increases opportunity for improved nutrient intake and healthier body weight through breakfast consumption, especially whole grain RTE cereals, as recommended by the Dietary Guidelines 2010.
美国儿童的营养不足和超重/肥胖率很高;其他国际研究也报告了类似的关联。学校早餐计划(SBP)可能有助于缓解美国年轻人的这些状况。本研究调查了即食(RTE)早餐谷物的消费与学生(SBP 参与者和非参与者)饮食营养摄入和体重状况之间的关系。
数据来自于 2004-2005 年进行的第三次学校营养饮食评估研究(SNDA-III)。分析包括了所有 2298 名 SNDA-III 参与者(年龄在 5-18 岁之间),他们完成了饮食回忆,其父母完成了访谈。学生分为不吃早餐和吃早餐两类;吃早餐的学生分为 SBP 参与(SBP 参与者与非参与者)和早餐类型(有 RTE 谷物和无 RTE 谷物)。在调整了协变量后,分析估计了这些分类与每日总营养素摄入和与体重相关的指标之间的关联。
与不吃谷物早餐的人相比,RTE 谷物早餐消费者(无论是否参与 SBP)的维生素 A、铁和全谷物摄入量更大。与不吃早餐的人相比,早餐消费者(无论是否参与 SBP 以及早餐类型如何)的维生素 A 和 C、钙、铁、膳食纤维和全谷物摄入量更大。
SBP 通过早餐消费,特别是按照 2010 年饮食指南推荐的 RTE 全谷物早餐,增加了改善营养摄入和更健康体重的机会。
