The evidence-based nutrition standards of the Healthy, Hunger-Free Kids Act of 2010 significantly improved school meal nutrition, yet little is known about how school food authorities (SFAs) were supported to translate the standards into practice in schools.
This study tested whether or not 2 implementation supports, SFA receipt of training/technical assistance (TA) and purchase of new equipment, for implementing the nutrition standards were associated with the nutritional quality of school lunches.
This study used a cross-sectional design.
PARTICIPANTS/SETTING: The study sample included 365 SFAs derived from the US Department of Agriculture's School Nutrition and Meal Cost Study (2014 to 2015 school year), the only national data of school nutrition environments since the Healthy, Hunger-Free Kids Act of 2010.
Implementation supports included reported participation in training/TA and the purchase of new equipment between the 2012 to 2013 (year of policy adoption) and 2014 to 2015 school years. The primary outcome, nutritional quality of school lunches served, was defined as low/high Healthy Eating Index 2010 scores during the 2014 to 2015 school year. Secondary implementation supports included the number of areas covered by training/TA, the adequacy of training/TA, and the degree of implementation challenges.
Multivariable-adjusted logistic regression models assessed if receipt of implementation supports was associated with lunch Healthy Eating Index 2010 scores.
The median lunch Healthy Eating Index 2010 score was 81.7 (95% CI 80.4 to 82.9). Most SFAs (78.4%, 95% CI 72.0% to 85.0%) reported having participated in training/TA and one-third (33.8%, 95% CI 24.4% to 43.2%) reported having purchased new equipment-neither were associated with the odds of having higher Healthy Eating Index 2010 scores for lunches served at the time of data collection.
Many SFAs accessed implementation supports to adopt the nutrition standards. Information on dose, quality, and nutrition-related impact of implementation supports using measures of change are needed to determine how best to support SFAs with implementation of new nutrition standards.
2010年《健康、无饥饿儿童法案》中基于证据的营养标准显著改善了学校膳食营养,但对于学校食品管理部门(SFAs)如何获得支持以将这些标准在学校付诸实践却知之甚少。
本研究检验了两种实施支持措施,即SFAs接受培训/技术援助(TA)以及购买新设备以实施营养标准,是否与学校午餐的营养质量相关。
本研究采用横断面设计。
参与者/研究背景:研究样本包括从美国农业部学校营养与膳食成本研究(2014至2015学年)中选取的365个SFAs,这是自2010年《健康、无饥饿儿童法案》以来唯一关于学校营养环境的全国性数据。
实施支持措施包括报告在2012至2013年(政策采用年份)和2014至2015学年期间参与培训/TA以及购买新设备的情况。主要结局,即所提供学校午餐的营养质量,定义为2014至2015学年期间健康饮食指数2010得分的低/高。次要实施支持措施包括培训/TA覆盖的领域数量、培训/TA的充分性以及实施挑战的程度。
多变量调整逻辑回归模型评估了获得实施支持措施是否与午餐健康饮食指数2010得分相关。
2010年午餐健康饮食指数的中位数得分是81.7(95%可信区间80.4至82.9)。大多数SFAs(78.4%,95%可信区间72.0%至85.0%)报告参与了培训/TA,三分之一(33.8%,95%可信区间24.4%至43.2%)报告购买了新设备,在数据收集时,这两者均与所提供午餐具有更高健康饮食指数2010得分的几率无关。
许多SFAs获得了实施支持措施以采用营养标准。需要利用变化量度来获取关于实施支持措施的剂量、质量和营养相关影响的信息,以确定如何最好地支持SFAs实施新的营养标准。
