The Impact of a Multipronged Intervention to Increase School Lunch Participation among Secondary School Students in an Urban Public School District.

Introduction: Schools meals offer a critical opportunity for improving youths' diets, particularly for economically disadvantaged students. We examine the impact of a multipronged intervention to increase middle and high school students' lunch participation in an urban school district. Methods: In school years 2015-2016 through 2017-2018, a quasi-experimental study was conducted in 24 secondary schools, half (n = 12) of which received the following intervention: cafeteria redesign, additional school lunch points-of-sale (mobile carts and vending machines), and teacher education. Results: From baseline to follow-up, lunch participation dropped 4.1% in intervention and 5.1% in comparison schools (difference-in-difference 1.0%, 95% CI 0.5-1.4). The overall decline in lunch participation occurred simultaneously with a drop-in free or reduced-price meal eligibility (from 72% to 58%) across all schools, which is likely related to changing local economic conditions, including a county-wide minimum wage increase that began in summer 2015. Among students eligible for free or reduced-price meals, participation decreased 1.8% in intervention and 4.9% in comparison schools (difference-in-difference 3.1%, 95% CI: 2.5-3.7), with a larger difference-in-difference seen in high schools (5.0%, 95% CI: 4.2-5.9) than middle schools (1.8%, 95% CI: 0.8-2.6). Conclusions: While this intervention demonstrated a modest, but significant relative increase in school lunch participation, the effect was not sufficient to halt large district-wide declines in participation during this study period. Given the significant time, money, and political capital required to implement the intervention, districts should carefully consider similar investments. Broader public policies or other changes to economic conditions that affect eligibility for means-tested benefits-in this case, a strengthening local economy coupled with an increased local minimum wage-may influence school lunch participation more than school-level interventions

Sugar-Sweetened Beverage and Water Intake in Relation to Diet Quality in U.S. Children.

Introduction: Sugar-sweetened beverages (SSBs) are a major contributor to children’s added sugar consumption. This study examines whether children’s SSB and water intake are associated with diet quality and total energy intake.Methods: Using data on children ages 2–18 years from the 2009–2014 National Health and Nutrition Examination Survey, linear regression models were used to analyze SSB and water intake in relation to Healthy Eating Index (HEI-2010) scores and total energy intake. Generalized linear models were used to analyze SSB and water intake in relation to the HEI-2010 scores. Analyses were conducted including and excluding caloric contributions from SSBs, and were conducted in 2016–2017.Results: SSB intake was inversely associated with the HEI-2010 total scores (9.5-point lower score comparing more than two servings/day with zero servings/day, p-trend<0.0001) and positively associated with total energy intake (394 kcal higher comparing more than two servings/day with zero servings/day, p-trend<0.0001). The associations between SSB and HEI-2010 total scores were similar when SSBs were excluded from HEI-2010 calculations. Water intake was positively associated with HEI-2010 total scores, but not associated with total energy intake. SSB intake was inversely associated with several HEI-2010 component scores, notably vegetables, total fruit, whole fruit, greens and beans, whole grains, dairy, seafood and plant proteins, and empty calories. Water intake was positively associated with most of the same HEI-2010 component scores.Conclusions: Children who consume SSBs have poorer diet quality and higher total energy intake than children who do not consume SSBs. Interventions for obesity and chronic disease should focus on replacing SSBs with water and improving other aspects of diet quality that correlate with SSB consumption

Effect of Removing Chocolate Milk on Milk and Nutrient Intake Among Urban Secondary School Students.

IntroductionSchools across the United States have removed sweetened, flavored milk from cafeterias to reduce students' sugar consumption and improve their health. However, evidence on the impact of the removal is limited. We examined the effect of a policy that removed chocolate milk from secondary schools on students' milk consumption and estimated milk-related nutrient intake.MethodsWe collected data on milk selection and consumption during 1 lunch period in 24 California public secondary schools pre-policy (N = 3,158 students in 2016) and post-policy (N = 2,966 students in 2018). Schools had a student population that was 38% Asian and 29% Latino, with 63% qualifying for free or reduced-price meals. We used linear mixed effects models to assess changes in milk selection and waste, and we estimated related changes in added sugars, calcium, protein, and vitamin D consumed from milk.ResultsThe proportion of students selecting milk declined 13.6%, from 89.5% pre-policy to 75.9% post-policy (95% CI for difference, 10.8% tο 16.4%), but the proportion of milk wasted remained stable (37.1% vs 39.3%; 95% CI for difference, -0.2% to 4.6%). Although average per-student milk consumption declined by less than 1 ounce per student (from 4.8 oz to 3.8 oz; 95% CI for difference, -1.1 oz to -0.7 oz), we observed no significant reductions in average per-student intake of calcium, protein, or vitamin D from milk. Estimated added sugars from milk declined significantly, by 3.1 grams per student (95% CI, -3.2 g to -2.9 g).ConclusionRemoving chocolate milk modestly reduced student milk consumption without compromising average intake of key milk-related nutrients, and consumption of added sugars from milk declined significantly. Secondary schools should consider removing chocolate milk to support healthy beverage consumption

Evaluating Food Packaging Waste in Schools: A Systematic Literature Review

Public schools in the U.S. generate about 14,500 tons of municipal solid waste daily, and approximately 42% of that is food packaging generated by school foodservice, contributing significantly to the global packaging waste crisis. This literature review summarizes methods used to evaluate food packaging waste in school foodservice. This review has two objectives: first, to understand which methodologies currently exist to evaluate food packaging waste generation and disposal in school foodservice; and second, to describe the creation of and share a practical standardized instrument to evaluate food packaging waste generation and disposal in school foodservice. A systematic review was conducted using the following search terms: solid waste, school, cafeteria and food packaging, waste, and school. The final review included 24 studies conducted in school environments (kindergarten through twelfth grade or college/university), 16 of which took place in the U.S. Food packaging waste evaluations included objective methods of waste audits, models, and secondary data as well as subjective methods of qualitative observations, questionnaires, interviews, and focus groups. Large variation exists in the settings, participants, designs, and methodologies for evaluating school foodservice packaging waste. Lack of standardization was observed even within each methodology (e.g., waste audit). A new instrument is proposed to support comprehensive and replicable data collection, to further the understanding of school foodservice food packaging waste in the U.S., and to reduce environmental harms

Post–Healthy, Hunger-Free Kids Act Adherence to Select School Nutrition Standards by Region and Poverty Level: The Healthy Communities Study

ObjectiveThis study determined the extent to which schools adhered to select nutrition and wellness provisions of the 2010 Healthy, Hunger-Free Kids Act and examined differences by US region and school poverty level.DesignComparison of cross-sectional observational data from the Healthy Communities Study (2013-2015) by region and school poverty level.ParticipantsA total of 401 US elementary and middle schools.Main outcome measuresAdherence with federal nutrition standards for meals and competitive foods; extent of implementation of select aspects of school wellness policies.AnalysisDescriptive statistics and multivariate regression were used. Differences were examined by school poverty level and region, adjusting for other school- and community-level covariates.ResultsMost schools reported meeting reimbursable school meal nutrition standards (74%); more schools in the West met nutrition standards (82%) than in the Midwest (64%). Most grains offered at lunch were whole grain-rich (82%), and most competitive foods complied with standards (78%) before they were required. Most schools had a wellness coordinator (80%). Lowest levels of adherence were reported for guidelines for classroom or school event foods. No differences were observed by school poverty level.Conclusions and implicationsFindings suggest that Healthy Hunger-Free Kids Act provisions were feasible across a wide variety of schools, and schools successfully implemented reimbursable school meal nutrition standards regardless of school poverty level

Implementation of Universal School Meals during COVID-19 and beyond: Challenges and Benefits for School Meals Programs in Maine.

School meals play a major role in supporting children's diets and food security, and policies for universal school meals (USM) have the potential to contribute to positive child health outcomes. During the COVID-19 pandemic, schools provided free school meals to all students in the United States, but this national USM policy ended in school year (SY) 2022-2023; however, a few states have adopted policies to continue USM statewide for SY 2022-2023. Research examining the challenges and strategies for successful continuation of USM is essential, along with studying pandemic-related challenges that are likely to persist in schools. Therefore, we conducted a study in Maine (with a USM policy) to evaluate the impact of COVID-19 and the concurrent implementation of USM, as well as examine differences in implementation by school characteristics, throughout the state. A total of n = 43 school food authorities (SFAs) throughout Maine completed surveys. SFAs reported multiple benefits of USM including increased school meal participation; reductions in the perceived stigma for students from lower-income households and their families; and no longer experiencing unpaid meal charges and debt. SFAs also experienced challenges due to the COVID-19 pandemic, particularly regarding costs. When considering future challenges, most respondents were concerned with obtaining income information from families, product and ingredient availability, and the costs/financial sustainability of the school meal programs. Overall, USM may have multiple important benefits for students and schools, and other states should consider implementation of a USM policy
