We analyzed the impact of Connecticut legislation incentivizing voluntary school district-level elimination of unhealthy competitive foods on National School Lunch Program (NSLP) participation.
We analyzed data on free, reduced, and paid participation in the NSLP from 904 schools within 154 Connecticut school districts from the 2004-2005 to the 2009-2010 school year, resulting in 5064 observations of annual school-level meal participation. We used multilevel regression modeling techniques to estimate the impact of the state competitive food legislation on the count of NSLP lunches served per student in each school.
Overall, the state statute was associated with an increase in school lunch participation. We observed increases between 7% and 23% for middle- and high-school meal programs, and a slight decrease of 2.5% for the elementary school free meal eligibility category, leading to an estimated revenue increase of roughly $30 000 for an average school district per school year.
This study provides support for national implementation of proposed rigorous competitive food standards that can improve the health of students while supporting local school district finances.
我们分析了康涅狄格州立法激励自愿学区层面消除不健康的竞争食品对国家学校午餐计划（NSLP）参与的影响。
我们分析了 2004-2005 学年至 2009-2010 学年期间来自康涅狄格州 154 个学区的 904 所学校的免费、减少和付费参与国家学校午餐计划的数据，共获得了 5064 个学校层面的年度膳食参与观察值。我们使用多层回归建模技术来估计州竞争性食品立法对每个学校每个学生提供的 NSLP 午餐数量的影响。
总体而言，州法规与学校午餐参与度的增加有关。我们观察到中学和高中膳食计划的参与率增加了 7%至 23%，而小学免费膳食资格类别略有下降 2.5%，这导致每个学区每所学校的年收入估计增加约 30000 美元。
这项研究为全国实施拟议的严格竞争食品标准提供了支持，这些标准可以在支持地方学区财政的同时改善学生的健康。
