Schools are in a unique position to help improve youth dietary behaviors and prevent and reduce obesity. In most schools, foods and beverages are made available to students through the U.S. Department of Agriculture (USDA) school meal programs and the sale of competitive foods, which are any foods and beverages sold at a school separately from the USDA school meal programs. Foods and beverages sold through the USDA school meal programs must meet federal nutrition requirements. Competitive foods are not subject to any federal nutrition standards unless they are sold inside the food service area during mealtimes. A 2007 Institute of Medicine (IOM) report concluded that schools should limit the availability of less nutritious competitive foods or include more nutritious foods and beverages if they make competitive foods available. To identify the types of competitive foods and beverages available for purchase from vending machines or at school stores, canteens, or snack bars, CDC analyzed data from the 2006 School Health Profiles for public secondary schools in 36 states and 12 large urban school districts. CDC also compared 2004 and 2006 data among 24 states and nine large urban school districts. This report summarizes the results of these analyses, which indicated that, from 2004 to 2006, the median percentage of secondary schools across states allowing students to purchase chocolate candy and salty snacks that are not low in fat decreased; however, in 2006, secondary schools still offered less nutritious foods and beverages that compete with school meals. School and public health officials should work together with families to provide foods and beverages at school that follow the IOM recommendations.
学校在帮助改善青少年饮食行为以及预防和减少肥胖方面具有独特作用。在大多数学校,学生可通过美国农业部(USDA)的学校供餐计划以及竞争性食品的销售获取食品和饮料,竞争性食品是指学校内除USDA学校供餐计划之外单独出售的任何食品和饮料。通过USDA学校供餐计划出售的食品和饮料必须符合联邦营养要求。竞争性食品不受任何联邦营养标准的约束,除非它们在就餐时间在餐饮服务区内出售。2007年医学研究所(IOM)的一份报告得出结论,学校应限制营养较差的竞争性食品的供应,或者如果提供竞争性食品,应增加营养丰富的食品和饮料。为了确定可从自动售货机或学校商店、食堂或小吃店购买的竞争性食品和饮料的类型,疾病预防控制中心(CDC)分析了来自36个州和12个大型城市学区的2006年公立中学学校健康档案数据。CDC还比较了24个州和9个大型城市学区2004年和2006年的数据。本报告总结了这些分析结果,结果表明,从2004年到2006年,各州允许学生购买非低脂巧克力糖果和咸味小吃的中学比例中位数有所下降;然而,在2006年,中学仍然提供与学校膳食相竞争的营养较差的食品和饮料。学校和公共卫生官员应与家庭共同努力,在学校提供符合IOM建议的食品和饮料。
