Abstract

The Healthy, Hunger-Free Kids Act of 2010 authorized the Secretary of the US Department of Agriculture to establish science-based nutrition standards for competitive foods and beverages sold in school that are, at a minimum, aligned with the 2010 Dietary Guidelines for Americans (DGA), while still providing districts with discretion in regulating the competitive food and beverage environment. The objective of this study was to examine the extent to which district competitive food and beverage policies had specific and required limits aligned with 2010 DGA recommendations, and to inform US Department of Agriculture efforts as they develop competitive food and beverage standards. Competitive food and beverage policies were compiled for the 2009-2010 school year from a nationally representative sample of 622 districts. Each policy was double-coded for compliance with selected 2010 DGA recommendations (ie, restrictions on sugars, fats, trans fats, and sodium in foods and restrictions on regular soda, other sugar-sweetened beverages, and fat content of milk). Descriptive statistics were computed, clustered to account for the sample design, and weighted to account for districts nationwide. District nutrition policies were strongest for elementary schools. Nationwide, <5% of districts met or exceeded all of the previously mentioned nutrient requirements examined. Fat and sugar content of foods and soda availability were more commonly addressed. Areas that require attention include stronger nutrition standards at the secondary level, limits on trans fats, sodium, sugar-sweetened beverages other than soda, and fat content of milk, and greater availability of produce and whole grains at all sale locations.

摘要

2010 年《健康,无饥饿儿童法案》授权美国农业部部长为学校销售的竞争食品和饮料制定基于科学的营养标准,这些标准至少与 2010 年《美国人饮食指南》(DGA)保持一致,同时仍然为地区提供调节竞争食品和饮料环境的酌处权。本研究的目的是调查地区竞争食品和饮料政策与 2010 年 DGA 建议具体和必需的限制相符合的程度,并为美国农业部制定竞争食品和饮料标准提供信息。从全国代表性样本中抽取了 622 个地区,为 2009-2010 学年汇编了竞争食品和饮料政策。对每个政策进行了双重编码,以遵守 2010 年 DGA 建议的选择(即限制食品中的糖、脂肪、反式脂肪和钠,以及限制普通苏打水、其他含糖饮料和牛奶中的脂肪含量)。计算了描述性统计数据,聚类以考虑样本设计,并加权以考虑全国的地区。地区营养政策在小学中最强。全国范围内,<5%的地区满足或超过了之前提到的所有营养要求。食品和苏打水的脂肪和糖含量更常被提及。需要注意的领域包括在中学阶段加强营养标准,限制反式脂肪、钠、除苏打水以外的含糖饮料和牛奶中的脂肪含量,以及在所有销售点增加农产品和全谷物的供应。
