背景儿童一天中的大部分时间都在学校度过，当局呼吁改善学校的食物环境。然而，自2006-2007年联邦健康政策生效以来，是否发生了变化尚不清楚。目的我们检查了公立和私立小学的学校食物环境是否随着时间的推移而发生变化，并检查了学校类型和地理分区的变化。设计和参与者调查数据来自2006-2007学年和2009-2010学年全国代表性小学样本(分别为578和680所公立学校，259和313所私立学校)。主要结果衡量主题评估包括竞争性食品、校餐和其他与食品相关的做法(如学校花园和营养教育)。计算了16个项目的食物环境总分，可能的分数范围从0(最不健康)到100(最健康)。使用多元回归模型分析学校食品环境总分和组成项目随时间的变化，以及美国人口普查部门的变化。结果许多做法都得到了改善，如参加学校菜园或农场到学校的计划，午餐中可获得全谷物和低脂牛奶。尽管学校食物环境得分显著增加，但变化幅度很小；截至2009-2010年，公立学校的平均得分为53.5(2006-2007年为50.1)，私立学校为42.2(2006-2007年为37.2)。公立学校得分高于私立学校(P
Background Children spend much of their day in school, and authorities have called for improvements in the school food environment. However, it is not known whether changes have occurred since the federal wellness policy mandate took effect in 2006-2007.Objective We examined whether the school food environment in public and private elementary schools changed over time and examined variations by school type and geographic division.Design and participants Survey data were gathered from respondents at nationally representative samples of elementary schools during the 2006-2007 and 2009-2010 school years (respectively, 578 and 680 public schools, and 259 and 313 private schools).Main outcome measures Topics assessed included competitive foods, school meals, and other food-related practices (eg, school gardens and nutrition education). A 16-item food environment summary score was computed, with possible scores ranging from 0 (least healthy) to 100 (healthiest).Analyses Multivariate regression models were used to examine changes over time in the total school food environment score and component items, and variations by US census division.Results Many practices improved, such as participation in school gardens or farm-to-school programs, and availability of whole grains and only lower-fat milks in lunches. Although the school food environment score increased significantly, the magnitude of change was small; as of 2009-2010 the average score was 53.5 for public schools (vs 50.1 in 2006-2007) and 42.2 for private schools (vs 37.2 in 2006-2007). Scores were higher in public schools than in private schools (P
