Federal nutritional guidelines apply to school foods provided through the national school lunch and breakfast programs, but few federal regulations apply to other foods and drinks sold in schools (labeled "competitive foods"), which are often high in calories, fat and sugar. Competitive food policies among school districts are increasingly viewed as an important modifiable factor in the school nutrition environment, particularly to address rising rates of childhood overweight. Congress passed legislation in 2004 requiring all school districts to develop a Wellness Policy that includes nutrition guidelines for competitive foods starting in 2006-2007. In addition, the Institute of Medicine (IOM) recently published recommendations for schools to address childhood obesity.
Representatives of school districts with the largest student enrollment in each state and D.C. (N = 51) were interviewed in October-November 2004 about each school district's nutrition policies on "competitive foods." District policies were examined and compared to the Institute of Medicine's recommendations for schools to address childhood obesity. Information about state competitive food policies was accessed via the Internet, and through state and district contacts.
The 51 districts accounted for 5.9 million students, representing 11% of US students. Nineteen of the 51 districts (39%) had competitive food policies beyond state or federal requirements. The majority of these district policies (79%) were adopted since 2002. School district policies varied in scope and requirements. Ten districts (53%) set different standards by grade level. Most district policies had criteria for food and beverage content (74%) and prohibited the sale of soda in all schools (63%); fewer policies restricted portion size of foods (53%) or beverages (47%). Restrictions more often applied to vending machines (95%), cafeteria à la carte (79%), and student stores (79%) than fundraising activities (47%). Most of the policies did not address more comprehensive approaches to the school nutrition environment, such as nutrition education (32%) or advertising to students (26%), nor did they include guidelines on physical education (11%). In addition, few policies addressed monitoring (32%) or consequences for non-compliance (11%). No policy restricted foods sold for after-school fundraising or required monitoring physical health indicators (e.g. BMI).
When compared to the Institute of Medicine's recommendations for schools' role in preventing obesity, none of the nutrition policies among each state's largest school district had addressed all the recommendations by 2004-2005. Nutritionists, nurses, pediatricians, parents, and others concerned about child health have an unprecedented opportunity to help shape and implement more comprehensive school district nutrition policies as part of the Congressional requirement for a "Wellness Policy" by 2006-2007.
联邦营养指南适用于通过全国学校午餐和早餐计划提供的学校食品,但很少有联邦法规适用于学校出售的其他食品和饮料(称为“竞争性食品”),这些食品通常热量、脂肪和糖分含量很高。学区的竞争性食品政策越来越被视为学校营养环境中一个重要的可改变因素,特别是为了解决儿童超重率不断上升的问题。国会在2004年通过立法,要求所有学区制定一项健康政策,其中包括从2006 - 2007学年开始的竞争性食品营养指南。此外,医学研究所(IOM)最近发布了关于学校应对儿童肥胖问题的建议。
2004年10月至11月,对每个州及华盛顿特区学生人数最多的学区代表(N = 51)进行了访谈,了解各学区关于“竞争性食品”的营养政策。对学区政策进行了审查,并与医学研究所关于学校应对儿童肥胖问题的建议进行了比较。通过互联网以及与州和学区的联系获取了有关州竞争性食品政策的信息。
这51个学区共有590万名学生,占美国学生总数的11%。51个学区中有19个(39%)制定了超出州或联邦要求的竞争性食品政策。这些学区政策中的大多数(79%)是2002年以后采用的。学区政策在范围和要求上各不相同。10个学区(53%)按年级设定了不同标准。大多数学区政策有食品和饮料内容标准(74%),并禁止在所有学校销售汽水(63%);较少政策限制食品(53%)或饮料(47%)的份量大小。与筹款活动(47%)相比,限制措施更多地适用于自动售货机(95%)、自助餐厅点菜(79%)和学生商店(79%)。大多数政策没有涉及学校营养环境的更全面方法,如营养教育(32%)或针对学生的广告(26%),也没有包括体育教育指南(11%)。此外,很少有政策涉及监督(32%)或违规后果(11%)。没有政策限制课后筹款销售的食品,也没有要求监测身体健康指标(如体重指数)。
与医学研究所关于学校在预防肥胖方面作用的建议相比,到2004 - 2005年,每个州最大的学区中没有一项营养政策涵盖了所有建议。营养学家、护士、儿科医生、家长以及其他关注儿童健康的人士有前所未有的机会,作为2006 - 2007学年国会对“健康政策”要求的一部分,帮助制定和实施更全面的学区营养政策。
