The relationship between community food environment around schools and student meal participation: the role of school CEP participation status.

BACKGROUND: Despite the many benefits of school meals, not all students participate. One reason students may not participate in school meals is because they instead purchase breakfast or lunch from food outlets located around schools that mostly carry unhealthy items. This study examined whether school participation in the Community Eligibility Provision (CEP), which allows qualifying schools to serve free meals to all students, moderated the association between the community food environment around schools and student meal participation. METHODS: This study employed a longitudinal repeated-measures design using school-level data collected between 2014 and 2020 within four low-income school districts (n = 126 schools) in the US. We obtained meal participation data from state records and created a measure characterizing the community food environment within 0.25 miles of schools (characterized as low-density of unhealthy food outlets vs. high-density of unhealthy food outlets) through a latent class analysis. Regression analysis estimated associations between community food environments, CEP participation, and participation rates in school breakfast and school lunch, assessed in separate models. RESULTS: While no moderating effect of school CEP status was observed for breakfast or lunch participation, school breakfast participation was predicted to be 4% lower in high-density food environments than in low-density environments (P-value = .049) among non-CEP schools, and there was no difference in participation by the community food environment among CEP-participating schools. Differences in breakfast participation by the community food environment among non-CEP schools were mostly attributable to middle/high schools, with participation predicted to be 10% lower in high-density environments than in low-density environments among non-CEP middle/high schools (P-value < .001), whereas such a difference in participation was not observed among non-CEP elementary schools. CONCLUSIONS: Negative associations between food environment around schools and school breakfast participation were observed only among middle and high schools not participating in CEP, suggesting that policy actions to increase access to free school meals may benefit students, particularly older children and adolescents.

Nutritional, environmental and economic implications of children plate waste at school: a comparison between two Italian case studies.

OBJECTIVE: This study aims at comparing two Italian case studies in relation to schoolchildren's plate waste and its implications, in terms of nutritional loss, economic cost and carbon footprint. DESIGN: Plate waste was collected through an aggregate selective weighting method for 39 d. SETTING: Children from the first to the fifth grade from four primary schools, two in each case study (Parma and Lucca), were involved. RESULTS: With respect to the served food, in Parma, the plate waste percentage was lower than in Lucca (P < 0·001). Fruit and side dishes were highly wasted, mostly in Lucca (>50 %). The energy loss of the lunch meals accounted for 26 % (Parma) and 36 % (Lucca). Among nutrients, dietary fibre, folate and vitamin C, Ca and K were lost at most (26-45 %). Overall, after adjusting for plate waste data, most of the lunch menus fell below the national recommendations for energy (50 %, Parma; 79 %, Lucca) and nutrients, particularly for fat (85 %, Parma; 89 %, Lucca). Plate waste was responsible for 19 % (Parma) and 28 % (Lucca) of the carbon footprint associated with the food supplied by the catering service, with starchy food being the most important contributor (52 %, Parma; 47 %, Lucca). Overall, the average cost of plate waste was 1·8 €/kg (Parma) and 2·7 €/kg (Lucca), accounting respectively for 4 % and 10 % of the meal full price. CONCLUSION: A re-planning of the school meals service organisation and priorities is needed to decrease the inefficiency of the current system and reduce food waste and its negative consequences.

"I Would Have My Children Participate IF ": Perceptions of Canadian Caregivers Towards School Food Programs.

Purpose: The Canadian federal government has expressed an intention to work with provinces and territories to develop a national school food program (SFP). This study aimed to explore caregivers' perception of attributes important to include in a future SFP.Methods: An online cross-sectional survey was conducted. Fifteen elementary schools from high, medium, or low median income neighbourhoods in Saskatoon were invited to participate. School principals sent a survey link to students' caregivers. The 37-item survey included an item with 15 statements asking caregivers to rate the importance of various components of a SFP. Descriptive statistics and exploratory factor analysis were conducted.Results: A total of 510 caregivers completed the survey (response rate of 52%). The factor analysis indicated four key components of a future SFP: (1) learning opportunities on growing and preparing food, (2) offering healthy food following Canada's Food Guide, (3) affordability of the meals offered, and (4) cultural adaptability of the meal program. Over 90% of caregivers thought providing healthy meals and ample time to eat meals to be very important.Conclusion: Our results indicate caregivers support multicomponent meal programs that, along with providing nutritious food, help children build healthy habits and sustainable food systems. These findings will help dietitians understand caregivers' perspectives to inform the design of a national SFP.

A qualitative study exploring the perceptions of children, parents and school staff towards the development and implementation of school lunch provision within primary schools in the Netherlands.

BACKGROUND: There is no tradition of serving school lunches in primary schools in the Netherlands. Most children tend to bring their own packed lunch, however these are often nutritionally suboptimal. While school lunch provision can aid healthy eating behavior amongst children, its introduction would constitute a profound change for children, parents and school staff. Therefore, this qualitative study aims to explore children's, parents and school staffs' perceptions of both the current lunch situation and the implementation of school lunch provision within primary schools in the Netherlands. METHODS: In this qualitative study we conducted nine interviews with school principals, 98 interviews with children, and held six focus groups with teachers and six with parents at primary schools in two Dutch cities. The data was analysed via iterative coding. RESULTS: The results showed that most children and parents are satisfied with the current lunch situation, although existing school food policies are not always put in place. Most teachers felt that children had insufficient time to consume their lunch in the current situation. The children were generally positive about the idea of a school lunch, and stressed that it was important to have the ability to choose. While both parents and school staff saw school lunch provision as an opportunity to educate families about healthy food options, they also expressed concern about who would be responsible, as well as the financial and organizational implications of its introduction. CONCLUSIONS: Perceptions of children, parents and school staff about a school provided lunch are mixed. A complex intervention such as a new school lunch program is difficult to envisage for all parties involved and more research is needed regarding the effects, organization, logistics and the costs of school lunch provision in the Netherlands.

Health, wellbeing and nutritional impacts after 2 years of free school meals in New Zealand.

In 2020, a government-funded healthy school lunch program was introduced in a quarter of New Zealand schools, selected due to high levels of socio-economic barriers. This study assesses the impact of the introduction of the school lunch program from family (whanau), student and school principal perspectives. Across four schools, we conducted five focus groups (two with secondary students and three with family members) and four school principal interviews. Participating schools represented a range of contexts: primary and secondary, schools with cooks in on-site kitchens and schools receiving meals delivered by external caterers. Thematic analysis was used to develop themes describing the health, wellbeing and nutritional impact of the program. Family participants were 82% Indigenous Maori and self-identified as having 'borderline' (73.5%) or no financial security (8.8%). Seven positive impact themes were identified: improved food security, enhanced equity, increased appreciation of healthy foods for students, enhanced mana (wellbeing) for all, reduced financial hardship/stress for families, opportunities for nutritional learning and recognition that appreciation and uptake happen over time. Four negative impact themes were identified: low uptake that created food waste, perception that healthy food is not palatable for students, lack of knowledge of the program and loss of agency for students. This is the largest intervention in nutrition and food security for children implemented in New Zealand since the 1930's. The first 2 years have offered wellbeing and financial benefits for students and families, particularly when school environments promote uptake. More involvement of students and family members in the program planning is essential.

Factors contributing to school food program acceptance: a Review of Canadian literature.

Diet quality and food security are a concern in school-aged children in Canada. In 2019, the Canadian federal government announced the intention to work towards a national school food program. Understanding the factors that impact school food program acceptability can inform planning to ensure that students are willing to participate. A scoping review of school food programs in Canada completed in 2019 identified 17 peer-reviewed and 18 grey literature publications. Of these, five peer-reviewed and nine grey literature publications included a discussion of factors that impact the acceptance of school food programs. These factors were thematically analyzed into categories: stigmatization, communication, food choice and cultural considerations, administration, location and timing, and social considerations. Considering these factors while planning can help to maximize program acceptability.

Diet quality and having sufficient food to eat are concerns in school-aged children in Canada. In 2019, the Canadian federal government announced the intention to work towards a national school food program. Providing food to children in schools can only address diet concerns if children participate. Understanding the factors that impact school food program acceptability can inform planning to contribute to program acceptance. Themes of factors contributing to school food program acceptance discussed in 14 publications were identified. Themes included stigmatization, communication, food choice and cultural considerations, administration, location and timing, and social considerations. Considering these factors while planning can help to maximize school food program acceptability.

Awareness of and Participation in School Food Programs in Youth from Six Countries.

BACKGROUND: School-based meal programs can promote healthy dietary intake in youth. However, limited data exist regarding the impact of income-targeted school meal programs across countries, particularly among food-insecure youth. OBJECTIVES: We examined self-reported awareness of and participation in free school meal programs, and associations with dietary intake in youth from 6 countries with differing national school meal policies. METHODS: Data were collected through the 2019 International Food Policy Study Youth Survey, a cross-sectional survey of 10,565 youth aged 10-17 y from Australia, Canada, Chile, Mexico, the United Kingdom, and the United States. Regression models examined: 1) country differences in awareness of and participation in breakfast and lunch programs; and 2) associations between lunch program participation and intake of fruit and vegetables, and "less healthy" foods during the previous school lunch day. RESULTS: Awareness of and participation in free breakfast and lunch programs varied across countries. Approximately half of USA and Chilean students participated in school lunch programs-the countries with the most comprehensive national policies-compared with one-fifth of students in the United Kingdom, and ∼5% in Australia, Canada, and Mexico (P < 0.001 for all contrasts). In the United States and Chile, more than two-thirds of youth with the highest level of food insecurity participated in lunch programs, compared with 45% in the United Kingdom, 27% in Canada, and ≤20% in Australia and Mexico. In all countries, youth reporting school lunch program participation were more likely to report fruit and vegetable intake during their previous school lunch (P < 0.001), and higher intake of "less healthy" food in all countries except the United States and Chile. CONCLUSIONS: More comprehensive national policies were associated with greater participation in school meal programs, particularly among youth at greatest risk of food insecurity, as well as healthier dietary intake from school lunches.

Effect of a free healthy school meal on fruit, vegetables and unhealthy snacks intake in Norwegian 10- to 12-year-old children.

BACKGROUND: Norwegian children have a lower intake of fruit, vegetables, and a higher intake of unhealthy snacks compared to dietary guidelines. Such dietary inadequacies may be detrimental for their current and future health. Schools are favorable settings to establish healthy eating practices. Still, no school meal arrangement is provided in Norway, and most children typically bring packed lunches from home. The aim of this study was to investigate whether serving a free healthy school meal for one year resulted in a higher intake of fruit and vegetables and a lower intake of unhealthy snacks in total among 10-12-year-olds in Norway. METHODS: The School Meal Project in Southern Norway was a non-randomized trial in two elementary schools in rural areas in the school year 2014/2015. The study sample consisted of 10- to 12-year-old children; an intervention group (N = 55) and a control group (N = 109) resulting in a total of 164 school children at baseline. A food frequency questionnaire was completed by the children at baseline, at five months follow-up and after one year to assess fruit, vegetable, and snacks intake. Multiple linear regression analyses were performed to assess intervention effects on overall intake of fruit and vegetables and unhealthy snacks. RESULTS: Serving of a free healthy school meal for one year was associated with a higher weekly intake of vegetables on sandwiches in the intervention group compared to the control group, adjusted for baseline intake (B: 1.11 (95% CI: .38, 1.85)) at the end of the intervention. No other significant intervention effects were found for the remaining fruit and vegetables measures. Serving of a free healthy school meal was not associated with a lower weekly intake of unhealthy snacks (i.e. potato chips, candy, sugar sweetened beverages) in the intervention group compared to the control group. CONCLUSIONS: A free healthy school meal was associated with a higher weekly intake of vegetables on sandwiches but did not significantly change any other investigated dietary behaviors. However, given the inadequate intake of vegetables among children and that even moderate improvements have public health relevance, a free healthy school meal for all school children could be beneficial.

Home-grown school feeding: assessment of a pilot program in Nepal.

BACKGROUND: The Nepal School Meals Program reached 600,000 schoolchildren in basic education in 2017 and plays a key role in the government's strategy to increase children's academic and nutritional outcomes. A large part of the program is implemented through cash transfers with schools responsible for the school meal delivery. Home-grown school feeding, an approach in which local communities are given greater control over the school meals program and part of the food is sourced locally, may strengthen local ownership and improve meal quality, but there is a lack of evidence for impact. METHODS: This study piloted home-grown school feeding in 30 schools reaching nearly 4000 children in Sindhupalchok and Bardiya districts in Nepal with the aim to assess operations and outcomes in comparison to the regular cash-based school meals program. The study used a one-time post evaluation with a mixed methods approach. Qualitative data were collected through 12 focus group discussions and 28 key informant interviews with government and school staff, parents, cooks, cooperative members, World Food Programme representatives and other stakeholders involved in the pilot program. The quantitative part applied a quasi-experimental design and used cross-sectional data collected from 1512 children in 30 pilot and 30 control schools. RESULTS: The quantitative data indicated that children in the pilot schools had a significantly higher provision of midday school meals (+ 19%; p < 0.01) and a higher school meal quality in terms of dietary diversity (+ 44%; p < 0.01) and nutritional content (e.g. a 21%-points higher consumption of vitamin A-rich fruit and vegetables; p < 0.01). The qualitative data identified key drivers of these positive outcomes as the use of standard meal options, capacity building of local stakeholders, strengthened community ownership and accountability mechanisms, and local food supply chains. Maintaining the observed gains would require a 20-33% increase in the current budget per school meal in addition to the cost of capacity building. CONCLUSIONS: This study for Nepal shows that home-grown school feeding strengthened operations of the school meals program and led to a significantly higher meal provision and quality of school meals.

Free school meals as an approach to reduce health inequalities among 10-12- year-old Norwegian children.

BACKGROUND: Children spend a considerable amount of time at school and consume at least one meal/day. This study aimed to investigate if a free, healthy school meal every day for one school year was associated with children's intake of healthy foods at school, weight status and moderating effects of socio-economic status. METHODS: A non-randomized study design with an intervention and a control group was used to measure change in children's dietary habits at lunchtime. In total, 164 children participated; 55 in the intervention group and 109 in the control group (baseline). Intervention-children were served a free, healthy school meal every school day for one year. Participating children completed a food frequency questionnaire at baseline, at five months follow-up and after one year. Children's anthropometrics were measured at all three timepoints. Intervention effects on children's Healthy food score, BMI z-scores, and waist circumference were examined by conducting a Repeated Measures Multivariate ANOVA. Moderating effects of children's gender and parental socio-economic status were investigated for each outcome. RESULTS: A significant intervention effect on children's outcomes (multivariate) between baseline and after one year (F = 2.409, p < 0.001), and between follow-up 1 at five months and after one year (F = 8.209, p < 0.001) compared to the control group was found. The Univariate analyses showed a greater increase in the Healthy food score of the intervention group between baseline and follow-up 1 (F = 4.184, p = 0.043) and follow-up 2 (F = 10.941, p = 0.001) compared to the control group. The intervention-children had a significant increase in BMI z-scores between baseline and follow-up 2 (F = 10.007, p = 0,002) and between follow-up 1 and 2 (F = 22.245, p < 0.001) compared to a decrease in the control-children. The intervention-children with lower socio-economic status had a significantly higher increase in Healthy food score between baseline and follow-up 2 than the control-children with lower socio-economic status (difference of 2.8 versus 0.94), but not among children with higher socio-economic status. CONCLUSIONS: Serving a free school meal for one year increased children's intake of healthy foods, especially among children with lower socio-economic status. This study may contribute to promoting healthy eating and suggests a way forward to reduce health inequalities among school children. TRIAL REGISTRATION: ISRCTN61703361 .

Daily distribution of free healthy school meals or food-voucher intervention? Perceptions and attitudes of parents and educators.

AIMS: To qualitatively evaluate the optimal intervention (food-voucher approach vs. free daily meal distribution), aimed at reducing food insecurity and promoting healthy eating among students attending public schools in socioeconomically disadvantaged areas. METHODS: We randomly assigned 34 schools to one of the two interventions: students in 17 schools received a daily lunch-box and parents in the other 17 schools received a food voucher of equal value once a month. All students were offered the opportunity to participate. We conducted 30 focus groups in all participating schools (17 in the meal distribution and 13 in the food voucher schools). Eligible participants included parents (n = 106), educators (n = 66) and school principals (n = 34). We qualitatively evaluated their perceptions and attitudes towards the program. RESULTS: Important differences were observed between the two approaches, with more favourable perceptions being reported for the meal distribution approach. More specifically, social stigmatization was minimized in the meal distribution approach, through the participation of all students, compared with the food-voucher participants who reported feelings of embarrassment and fear of stigmatization. Secondly, the meal distribution approach alleviated child food insecurity through the provision of the daily meal, while the food-voucher intervention helped manage household food insecurity, as vouchers were mainly used for purchasing food for family meals. Furthermore, the educational and experiential nature of the meal distribution approach intensified healthy eating promotion, while the food-voucher intervention was efficient mainly for conscious parents regarding healthy eating. CONCLUSIONS: The meal distribution intervention was considered more effective than the food-voucher one. Hence, for interventions aiming at tackling food insecurity of children and adolescents, public health focus could be oriented towards school-based in kind food assistance.

Intervention study on school meal habits in Norwegian 10-12-year-old children.

AIM: The aim of this study was to investigate whether a free school meal every day was associated with children's intake of healthy food during school. METHODS: A non-randomized study design with an intervention and a control group was used to measure change in children's meal habits at lunchtime. In total, 164 children participated; 55 in the intervention group and 109 in the control group. Children in the intervention group were served a free, healthy school meal every school day. Participating children completed a questionnaire at baseline and at 6 months' follow up. Possible associations were evaluated with a healthy food score, which was calculated based on a food frequency questionnaire on lunch habits at school. Chi-square and Independent Samples t-test were used to analyse the data. RESULTS: At baseline, there was no significant difference in the healthy food score between the intervention and the control group ( p = 0.08). Children in the intervention group increased their healthy food score significantly compared with children in the control group after 6 months ( p ⩽ 0.01). Change in the healthy food score was mainly due to an increase in the intake of fruit ( p ⩽ 0.01), vegetables ( p ⩽ 0.01) and fish spread ( p = 0.02); all in favour of the intervention group. CONCLUSIONS: A serving of a free school meal every day for 6 months increased children's intake of healthy food at lunchtime compared with the control group. Further studies are needed to establish possible long-term effects.

Impact of school lunch type on nutritional quality of English children's diets.

OBJECTIVE: Nutrient and food standards exist for school lunches in English primary schools although packed lunches brought from home are not regulated. The aim of the present study was to determine nutritional and dietary differences by lunch type. DESIGN: A cross-sectional survey was carried out in 2007 assessing diet using the Child and Diet Evaluation Tool (CADET), a validated 24 h estimated food diary. The data were analysed to determine nutritional and dietary intakes over the whole day by school meal type: school meals and packed lunches. SETTING: Fifty-four primary schools across England. SUBJECTS: Children (n 2709) aged 6-8 years. RESULTS: Children having a packed lunch consumed on average 11·0 g more total sugars (95 % CI 6·6, 15·3 g) and 101 mg more Na (95 % CI 29, 173 mg) over the whole day. Conversely, children having a school meal consumed, on average, 4·0 g more protein (95 % CI 2·3, 5·7 g), 0·9 g more fibre (NSP; 95 % CI 0·5, 1·3 g) and 0·4 mg more Zn (95 % CI 0·1, 0·6 mg). There was no difference in daily energy intake by lunch type. Children having a packed lunch were more likely to consume snacks and sweetened drinks; while children having a school meal were more likely to consume different types of vegetables and drink water over the whole day. CONCLUSIONS: Compared with children having a school meal, children taking a packed lunch to school consumed a lower-quality diet over the whole day, including higher levels of sugar and Na and fewer vegetables. These findings support the introduction of policies that increase school meal uptake.

The human rights framework, the school and healthier eating among young people: a European perspective.

OBJECTIVE: To give an account of provisions in the framework of international human rights and intergovernmental policy agreements in relation to eating at school and discuss how these provisions could be invoked to ensure healthy eating at school. DESIGN: A review of provisions in the international and European human rights frameworks and policy documents was performed in order to identify evidence and examples of provisions implying responsibilities of the school as a public service provider to ensure healthy eating. RESULTS: The review of the human rights and policy texts showed that there are a large number of provisions that can be invoked in support of measures at school which can contribute to ensuring healthier eating as well as better education supporting such measures. CONCLUSIONS: The international frameworks of human rights and intergovernmental policy agreements should be invoked and translated into concrete strategies, policies, regulations and accountability mechanisms at national, regional, local and school levels. Ensuring healthy eating should be a top priority among all stakeholders in and around the school environment since it is a good investment in children's short- and long-term health and educational achievements.

Can providing a morning healthy snack help to reduce hunger during school time? Experimental evidence from an elementary school in Connecticut.

While children may be naturally inclined to regulate their hunger, they are also guided by adults and influenced by environmental constraints regarding when and how much to eat. As such, the timing and availability of meals could alter a child's natural eating habits. This could impact the nutritional quality of what they eat as well. We conducted a field experiment with three fourth grade classes at a public elementary school in Eastern Connecticut to analyze if providing a nutritious snack one hour prior to lunch effects a child's level of hunger and consequently their lunch-time consumption. We found students shift their caloric and nutrient intake from lunch to snack time. In addition, we found a significant reduction in student hunger. Our results highlight the importance in considering the timing and quality of meals provided during school time. In our sample, current snack and lunch schedule may not be optimal and changing it can have an impact on the wellbeing of students. Providing healthful options for snack could be an effective way to improve student diets while preserving their ability to make their own choices.

Children Receiving Free or Reduced-Price School Lunch Have Higher Food Insufficiency Rates in Summer.

BACKGROUND: In 2012, 20% of households in the United States with children lacked consistent access to adequate food. Food insufficiency has significant implications for children, including poor physical and mental health outcomes, behavior problems, and low educational achievements. The National School Lunch Program (NSLP) is one policy solution to reduce food insufficiency among children from low-income families. OBJECTIVE: The objective of this project was to evaluate the association between NSLP participation and household food insufficiency by examining trajectories of food insufficiency over 10 calendar months. The calendar months included both nonsummer months when school is in session and summer months when school is out of session. METHODS: The study used the data from the Survey of Income and Program Participation and conducted linear growth curve analyses in the multilevel modeling context. Comparisons were made between the trajectories of food insufficiencies among recipients of free or reduced-price lunch and their counterparts who are eligible but choose not to participate in the program. RESULTS: Heads of households that included children receiving free or reduced-price lunch (n = 6867) were more likely to be female, black, unmarried, and unemployed, and have a lower educational attainment than those whose children were eligible but did not receive free or reduced-price lunch (n = 11,396). For households participating in the NSLP, the food insufficiency rate was consistent from January to May at ∼4%, and then increased in June and July to >5%. Meanwhile, food insufficiency among eligible nonrecipients was constant throughout the year at nearly 2%. CONCLUSIONS: The NSLP protects households from food insufficiency. Policies should be instituted to make enrollment easier for households.

A qualitative study exploring pupil and school staff perceptions of school meal provision in England.

Despite recent attempts to improve the quality of school meals in England through the introduction of school meal standards, uptake remains low. Since the introduction of the universal infant free school meal (UIFSM) scheme in September 2014 all pupils in Reception, Year 1 and Year 2 in English state-funded primary schools are eligible to receive a free lunch. This study aimed to explore the perceptions of pupils, catering managers and head teachers concerning school meal provision in eight primary schools in North England and provides a unique insight into each school's preparation for implementation of UIFSM. A total of thirty-two focus groups were conducted with sixty-four pupils aged 7-8 years (Year 3) and sixty-four pupils aged 9-10 years (Year 5) in June-July 2014, to explore perceptions of school meals. Interviews were carried out with six catering managers and five head teachers concerning catering and the impending implementation of UIFSM. Increasing acceptance of school meals could lead to improved uptake. Pupils desired increased choice and menu variety, including greater variety of vegetables and fruit. Caterers can influence the quantity and types of foods offered to pupils, and there are opportunities for them to promote healthy eating behaviours in the dining room. The important roles of school meal providers, caterers, pupils and parents need to be recognised to improve delivery and acceptability of school meals and ultimately school meal uptake. There were practical challenges to implementation of UIFSM, with some concerns expressed over its feasibility. Head teachers were mainly positive about the potential beneficial impacts of the scheme.

Effects of school meals based on the New Nordic Diet on intake of signature foods: a randomised controlled trial. The OPUS School Meal Study.

A New Nordic Diet (NND) was developed in the context of the Danish OPUS Study (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet). Health, gastronomic potential, sustainability and Nordic identity were crucial principles of the NND. The aim of the present study was to investigate the effects of serving NND school meals compared with the usual packed lunches on the dietary intake of NND signature foods. For two 3-month periods, 834 Danish children aged 8-11 years received NND school meals or their usual packed lunches brought from home (control) in random order. The entire diet was recorded over 7 consecutive days using a validated Web-based Dietary Assessment Software for Children. The NND resulted in higher intakes during the entire week (% increase) of root vegetables (116 (95 % CI 1·93, 2·42)), cabbage (26 (95 % CI 1·08, 1·47)), legumes (22 (95 % CI 1·06, 1·40)), herbs (175 (95 % CI 2·36, 3·20)), fresh berries (48 (95 % CI 1·13, 1·94)), nuts and seeds (18 (95 % CI 1·02, 1·38)), lean fish and fish products (47 (95 % CI 1·31, 1·66)), fat fish and fish products (18 (95 % CI 1·02, 1·37)) and potatoes (129 (95 % CI 2·05, 2·56)). Furthermore, there was a decrease in the number of children with zero intakes when their habitual packed lunches were replaced by NND school meals. In conclusion, this study showed that the children increased their intake of NND signature foods, and, furthermore, there was a decrease in the number of children with zero intakes of NND signature foods when their habitual packed lunches were replaced by school meals following the NND principles.

Perceived Influence of a State-Level Universal Free School Meal Policy on Households With Varying Income Levels: An Analysis of Parental Perspectives.

BACKGROUND: In the United States, a means-tested approach is often used to provide free or reduced-price meals (FRPM) to students from lower-income households. However, federal income thresholds do not account for regional cost of living variations. Thus, many ineligible households may be at risk for food insecurity. Universal free school meal (UFSM) policies may help address this issue, especially in states with a higher cost of living. OBJECTIVE: To evaluate parent perceptions of the influence of Massachusetts' statewide UFSM policy on households eligible and ineligible for FRPM. DESIGN: Cross-sectional survey of parents across income categories conducted during the 2022-2023 school year. PARTICIPANTS/SETTING: Massachusetts parents (N = 403) with children in grades kindergarten through grade 12 with incomes ranging from <185% of the federal poverty level to >300% of the federal poverty level. MAIN OUTCOME MEASURES: Parents' perceived influence of Massachusetts' UFSM policy on their child and household. STATISTICAL ANALYSES PERFORMED: Analysis of variance examined differences in the perceived impact of UFSM by FRPM eligibility, adjusting for demographic characteristics. RESULTS: Households that were FRPM eligible or near eligible were significantly more likely to report that their ability to have enough food for their family would be harder without UFSM (P < .0001) compared with those in the highest income category. Across all income categories, approximately 75% of parents reported that school meals should be free for all children, and UFSM saved their family money and time and reduced stress, with no significant differences by FRPM eligibility. Roughly half (52%) reported their household finances would be hurt and 42% of parents from households eligible for FRPM reported their child would be less likely to eat school meals if the UFSM policy ended. CONCLUSIONS: This study found strong parent support of UFSM policies regardless of income level. In addition, parents perceived that discontinuing UFSM may adversely influence school meal participation, including among students from lower-income households, as well as food security among households ineligible for FRPM, particularly in areas with higher costs of living. Policies to expand UFSM should be considered among additional states and at the national level.

Uncovering individualised treatment effects for educational trials.

Large-scale Randomised Controlled Trials (RCTs) are widely regarded as "the gold standard" for testing the causal effects of school-based interventions. RCTs typically present the statistical significance of the average treatment effect (ATE), which captures the effect an intervention has had on average for a given population. However, key decisions in child health and education are often about individuals who may be very different from those averages. One way to identify heterogeneous treatment effects across different individuals, not captured by the ATE, is to conduct subgroup analyses. For example, free school meal (FSM) pupils as required for projects funded by the Education Endowment Foundation (EEF) in England. These subgroup analyses, as we demonstrate in 48 EEF-funded RCTs involving over 200,000 students, are usually not standardised across studies and offer flexible degrees of freedom to researchers, potentially leading to mixed, if not misleading, results. Here, we develop and deploy an alternative to ATE and subgroup analysis, a machine-learning and regression-based framework to predict individualised treatment effects (ITEs). ITEs could show where an intervention worked, for which individuals, and to what extent. Our findings have implications for decision-makers in fields like education, healthcare, law, and clinical practices concerning children and adolescents.
