OBJECTIVES
We examined state laws affecting the school food environment and changes in these laws between 2003 to 2008.
METHODS
We used the Westlaw legal database to identify state-codified laws, with scoring derived from the updated School Nutrition-Environment State Policy Classification System, obtained from the Classification of Laws Associated With School Students Web site.
RESULTS
States significantly changed their school nutrition laws from 2003 to 2008, and many increased the stringency of the laws targeting competitive foods (snacks and entrées sold in competition with the school meal) and beverages sold in school and for in-school fundraising. Many states enacted laws that mandated the establishment of a coordinating or advisory wellness team or council. Stronger laws were enacted for elementary grades. We found tremendous variability in the strength of the laws and plenty of room for improvement.
CONCLUSIONS
State law governing school nutrition policies significantly changed from 2003 to 2008, primarily affecting the competitive food environment in schools. The extent to which changes in school nutrition laws will lead to desired health outcomes is an area for additional research.
目的
我们研究了影响学校食品环境的州法律，并考察了这些法律在 2003 年至 2008 年间的变化。
方法
我们使用 Westlaw 法律数据库来识别州法典化的法律，并根据从学校学生相关法律分类网站获取的最新学校营养环境州政策分类系统对其进行评分。
结果
各州在 2003 年至 2008 年间显著改变了学校营养法律，许多州提高了针对竞争食品（在与学校餐竞争中销售的小吃和主菜）和学校内销售以及校内筹款用饮料的法律的严格程度。许多州颁布了建立协调或咨询健康团队或委员会的法律。更严格的法律适用于小学。我们发现法律的强度存在巨大差异，还有很大的改进空间。
结论
2003 年至 2008 年间，管理学校营养政策的州法律发生了重大变化，主要影响了学校的竞争食品环境。学校营养法律的变化将在多大程度上导致预期的健康结果，这是一个需要进一步研究的领域。
