    英国穆斯林学校儿童(BMSC)必须根据其宗教信仰遵守特殊的清真饮食要求,这在英国的学校中通常是不存在的。这通常使BMSC在学校时仅限于素食,尽管这不是他们选择的饮食或偏好。这项研究探讨了关键利益相关者对BMSC学校膳食的公平性和可及性的看法,以及讨论根据社会正义为那些保持宗教饮食的人提供学校食物。这是在英格兰东北部以前针对BMSC在系统一级的采购和决策方面知识有限的情况下进行的。
    进行了定性研究设计。共有62名与会者(39名BMSC,15父母,和8名学校和餐饮工作人员)参加了半结构化面试或焦点小组。参与者来自六所学校,这些学校是根据他们不同的BMSC出勤率来选择的。该项目发生在2022年3月至2023年10月之间。
    结果表明,在学校已经满足不同的食物需求的地方,包括BMSC的饮食需求,食物选择在选择和数量上仍然有限。学校和餐饮工作人员表示,成本影响了他们的菜单开发过程。尽管如此,人们显然愿意了解文化食品的选择,以及如何在未来的学校菜单中实施这些选择。讨论的建议包括增加清真肉的使用,以便为BMSC提供更具包容性的学校食品体验。
    UNASSIGNED: British Muslim School Children (BMSC) are required to follow special halal dietary requirements in accordance with their religion, which is often not accounted for in British schools. This often leaves BMSC limited to a vegetarian diet while at school, despite this not being their chosen diet or preference. This study explores the perceptions of key stakeholders regarding fairness and accessibility of school meals for BMSC, as well as discussing school food provision for those maintaining a religious diet in light of social justice. This is in the context of limited knowledge previously being explored in the North East of England regarding procurement and decision-making at a systems level to cater for BMSC.
    UNASSIGNED: A qualitative research design was conducted. A total of 62 participants (39 BMSC, 15 parents, and 8 school and catering staff) took part in a semi-structured interview or focus group. Participants were recruited from six schools, with these schools selected based on their differing levels of BMSC in attendance. This project took place between March 2022 and October 2023.
    UNASSIGNED: Results suggested that where schools already catered for diverse food requirements, inclusive of BMSC dietary needs, food choices were still limited in the options and amount available. School and catering staff stated that cost implications contributed to their menu development process. Despite this, there was an evident willingness to learn about the cultural food options and how these can be implemented in future school menus. Suggestions discussed included an increase in the use of halal meat in order to provide a more inclusive school food experience for BMSC.

    背景:营养对发育和线性生长有影响。然而,一些研究检查了儿童年龄标准化身高与营养状况和饮食质量之间的联系。
    目的:这项研究的目的是在基于网络的泰国学校午餐计划下,发现学生的饮食消费与身高之间的关系。
    方法:人体测量数据和营养消耗来自24小时记录。使用Inmucal计算营养素消耗。父母和保管人的数据来自电子健康记录。
    结果:儿童身高与父母身高无相关性(P<0.720)。此外,年龄Z分(HAZ)身高较低的儿童的矿物质摄入量显着降低(铁,镁,和硒)和维生素(B6,B12,C,andE).另一方面,镁,硒,正常HAZ儿童的维生素B12和维生素E摄入量高于其监护人。
    结论:泰国学校午餐计划有效地维持了儿童的正常HAZ。建议在社区进行营养教育。
    BACKGROUND: Nutrition has an impact on development and linear growth. However, a few studies examine the connections between children\'s age-standardized height and their nutritional status and diet quality.
    OBJECTIVE: This study aimed to find a relationship between dietary consumption and height for age among school students under a web-based Thai school lunch program.
    METHODS: Anthropometric data and nutrient consumption were obtained from 24-hour records. Nutrient consumption was calculated using Inmucal. The parent and custodian\'s data were from the electronic health records.
    RESULTS: Children\'s heights were not correlated with parents\' heights (P<0.720). Moreover, children with low height-for-age Z-score (HAZ) had significantly lower intakes of minerals (iron, magnesium, and selenium) and vitamins (B6, B12, C, and E). On the other hand, magnesium, selenium, vitamin B12, and vitamin E intakes of the children with normal HAZ were higher than their custodians.
    CONCLUSIONS: The Thai school lunch program effectively maintains the normal HAZ of children. Nutritional education in the community is recommended.

    背景:不健康的饮食对欧洲儿童构成重大的公共卫生风险,导致超重和非传染性疾病患病率上升。孩子们每天在学校花费大量时间,包括午餐时间,因此,学校环境对于促进健康饮食和生活习惯至关重要。虽然有大量关于学校食品政策对健康和非健康结果的影响的文献,必须确定哪些政策是有效的,可以建议实施,以确保资源的有效利用。本文提出了一项范围审查方案,旨在绘制当前已发表的有关学校食品政策对健康结果的影响的文献。欧洲中学生的接受度和负担能力。此外,范围审查将绘制用于评估健康结果的测量图,接受和负担能力。
    方法:范围审查方案和审查遵循系统审查的首选报告项目和范围审查的Meta分析扩展。为了确定符合条件的研究,我们将搜索MEDLINE,PsycINFO,CINAHL和WebofScience。将检查所包含文章的参考列表以进行其他研究。此外,欧洲联盟成员国针对具体国家的部报告,英国,挪威,冰岛和瑞士将被确定。世卫组织和欧盟委员会网站也将被搜索相关报告。范围审查将包括2023年9月20日之前发表的文献。对学习设计和语言没有限制。筛选和数据提取将由三名评审员独立进行。分歧将通过讨论解决。预先测试的数据图表表将用于提取关键信息。研究结果将以表格和可视化摘要以及叙述性摘要形式呈现。
    背景:此范围审查不需要道德批准。我们的传播策略包括同行评审的出版物,会议向决策者介绍和建议。
    BACKGROUND: Unhealthy diets pose a significant public health risk among European children, contributing to the increasing prevalence of overweight and non-communicable diseases. Children spend a substantial amount of time at school daily, including lunchtime, so the school setting becomes crucial for promoting healthy diets and lifestyle habits. While there is a large body of literature on the impact of school food policies on health and non-health outcomes, it is essential to identify which policies are effective and can be recommended for implementation to ensure the efficient use of resources. This article presents a protocol for a scoping review that aims to map the current published literature on the effects of school food policies on health outcomes, acceptance and affordability in secondary school children in Europe. Moreover, the scoping review will map the measurements used to assess health outcomes, acceptance and affordability.
    METHODS: The scoping review protocol and review follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Review. To identify eligible studies, we will search MEDLINE, PsycINFO, CINAHL and Web of Science. The reference lists of the included articles will be checked for additional studies. In addition, country-specific ministry reports from Member States of the European Union, the UK, Norway, Iceland and Switzerland will be identified. The WHO and European Commission websites will also be searched for relevant reports. The scoping review will include literature published until 20 September 2023. No restrictions to study design and language will be applied. Screening and data extraction will be carried out independently by three reviewers. Disagreements will be resolved by discussion. A pretested data charting table will be used to extract key information. Findings will be presented in tabular and visualised summaries and a narrative summary.
    BACKGROUND: This scoping review does not require ethical approval. Our dissemination strategy comprises peer-reviewed publications, conference presentations and recommendations to policy-makers.

    背景:2016年,一项自愿的国家健康食品和饮料政策(以下简称,“政策”)的发布是为了鼓励新西兰的公立医院提供符合国家饮食指南的食品和饮料选择。五年后,20个组织中有8个采用了它,有几个人更愿意保留或更新自己的机构级版本。这项研究评估了员工和访客对政策的认识和支持,并收集了自该政策实施以来对食品环境变化的反馈。
    方法:2021年6月至2022年8月进行的横断面电子和纸质调查。描述性统计用于呈现定量结果。按照一般归纳法对自由文本答复进行了分析。按政策执行水平比较了定性和定量结果,以及参与者的种族和财务安全。
    结果:数据来自19个医疗机构的2,526名员工和261名访客。80%的员工和56%的访客了解该政策。工作人员和访客普遍支持该政策,不管他们是否意识到,大多数人都同意“医院应该是很好的榜样。“在反对这项政策的工作人员中,最常见的原因是选择自由。政策影响较大,积极和消极,关于毛利人和太平洋工作人员,由于更频繁的现场采购。大多数工作人员注意到自政策实施以来可用的食品和饮料的差异。对一些医院提供的各种选择有积极的反馈,但总体而言,40%的自由文本评论提到了有限的选择。74%的员工表示食品和饮料更昂贵。低收入员工/访客和轮班工人尤其受到选择减少和健康选择价格上涨的影响。
    结论:该政策导致新西兰医院食品和饮料的健康状况发生了显著变化,但伴随着人们对价值和选择减少的看法。虽然总体上得到了很好的支持,调查结果表明,改善食品和饮料政策实施的机会(例如,提供更多健康食品选择,更好地与员工接触,并保持健康选择的价格较低),并确认该政策可以扩展到其他公共工作场所。
    BACKGROUND: In 2016, a voluntary National Healthy Food and Drink Policy (hereafter, \"the Policy\") was released to encourage public hospitals in New Zealand to provide food and drink options in line with national dietary guidelines. Five years later, eight (of 20) organisations had adopted it, with several preferring to retain or update their own institutional-level version. This study assessed staff and visitors\' awareness and support for and against the Policy, and collected feedback on perceived food environment changes since implementation of the Policy.
    METHODS: Cross-sectional electronic and paper-based survey conducted from June 2021 to August 2022. Descriptive statistics were used to present quantitative findings. Free-text responses were analysed following a general inductive approach. Qualitative and quantitative findings were compared by level of implementation of the Policy, and by ethnicity and financial security of participants.
    RESULTS: Data were collected from 2,526 staff and 261 visitors in 19 healthcare organisations. 80% of staff and 56% of visitors were aware of the Policy. Both staff and visitors generally supported the Policy, irrespective of whether they were aware of it or not, with most agreeing that \"Hospitals should be good role models.\" Among staff who opposed the Policy, the most common reason for doing so was freedom of choice. The Policy had a greater impact, positive and negative, on Māori and Pacific staff, due to more frequent purchasing onsite. Most staff noticed differences in the food and drinks available since Policy implementation. There was positive feedback about the variety of options available in some hospitals, but overall 40% of free text comments mentioned limited choice. 74% of staff reported that food and drinks were more expensive. Low-income staff/visitors and shift workers were particularly impacted by reduced choice and higher prices for healthy options.
    CONCLUSIONS: The Policy led to notable changes in the healthiness of foods and drinks available in NZ hospitals but this was accompanied by a perception of reduced value and choice. While generally well supported, the findings indicate opportunities to improve implementation of food and drink policies (e.g. providing more healthy food choices, better engagement with staff, and keeping prices of healthy options low) and confirm that the Policy could be expanded to other public workplaces.

    目的:分析幼儿园前计划中提供的膳食的致癌性及其对社会经济弱势儿童的早期龋齿(ECC)风险的潜在影响。方法:这项研究在联合国儿童发展中心检查了超过43天的123份学校提供的膳食,奥克兰统一学区幼儿园计划的一部分。使用Evans等人开发的致龋指数。,对所供应的所有项目进行了食品和饮料的致龋潜力评估.结果:食品的平均每日致龋评分为6.57±1.3(标准偏差),饮料的平均每日致龋评分为2.89±0.78。早餐食品的致龋作用明显高于午餐或晚餐(P<0.05)。平均每日卡路里摄入量为1,459±336,与晚餐相比,午餐的卡路里含量具有统计学意义(P<0.05)。虽然液体可能不会显著增加龋齿风险,早餐食品成为一个潜在的问题。结论:这项研究的结果表明,学校膳食中提供的食物,特别是早餐,可能会影响社会经济弱势儿童的早期龋齿风险。鉴于ECC的流行及其社会负担,将食品和饮料致龋性评估纳入学校膳食计划可能有助于降低ECC发生率。美国农业部和学区在考虑食物的致龋潜力方面的合作可能有助于改善儿童早期的口腔健康结果。
    Purpose: To analyze the cariogenicity of meals served in a pre-kindergarten program and its potential influence on early childhood caries (ECC) risk in socioeconomically disadvantaged children. Methods: This study examined 123 school-provided meals over 43 days at the United Nation Childhood Development Center, part of the Oakland Unified School District pre-kindergarten program. Using cariogenicity indices developed by Evans et al., all items served were assessed for the cariogenic potential of both food and beverages. Results: The mean daily cariogenicity scores were 6.57±1.3 (standard deviation) for food and 2.89±0.78 for beverages. Breakfast foods were significantly more cariogenic than those served for lunch or supper (P<0.05). The mean daily calorie intake was 1,459±336, with lunch containing statistically higher calorie items compared to supper (P<0.05). While liquids may not significantly contribute to caries risk, breakfast foods emerged as a potential concern. Conclusions: This study\'s findings suggest that the food provided in school meals, particularly breakfast items, may impact early childhood caries risk among socioeconomically disadvantaged children. Given the prevalence of ECC and its societal burden, integrating assessments of food and beverage cariogenicity into school meal planning could be instrumental in mitigating ECC incidence. Collaboration between the United States Department of Agriculture and school districts in considering the cariogenic potential of foods may contribute to improved oral health outcomes in early childhood.

    白宫关于饥饿的国家战略,营养,健康包括向所有学生提供免费的校餐,无论收入如何,这在美国引发了争论。
    评估美国普遍免费学校餐(UFSM)与学校和学生成绩之间的关联。
    制定了专家小组知情方案,以评估比较UFSM计划的干预或队列研究,例如社区资格规定(CEP),2012年8月(不包括由于COVID-19大流行而导致的2020-2021年)在美国学校开展非UFSM课程。结果包括膳食参与率,出席,饮食摄入量和质量,食物浪费,经济影响,粮食不安全,人体测量学,纪律处分,污名,和羞辱。搜索Medline,Econlit,最终的业务来源,ERIC,Agricola,CabAbstracts,和CINAHL于2024年4月进行。两名研究人员筛选了纳入的文章,提取的数据,并评估了偏见的风险,在非随机干预研究工具中使用偏倚风险,对于每个纳入的研究。建议的分级,评估,发展,评估用于评估每个结果的证据的确定性。
    搜索确定了2784条记录,包括6项研究,代表超过11000个小学,中间,和高中。非随机干预研究进行差异或比率分析以调查CEP参与率,出席,人体测量学,和/或悬架。CEP与增加午餐(3项研究;中等确定性)和早餐(1项研究;非常低的确定性)相关。与没有UFSM的学校相比,有CEP的学校的入学率没有变化或有所改善(2项研究;确定性低)。CEP与较低的肥胖患病率(1项研究;非常低的确定性)和较少的悬浮(1项研究;非常低的确定性)相关。降低确定性评级的原因包括间接性(数据不能完全代表美国)和不一致性(少量研究限制了评估一致性的能力)。尽管有局限性,证据反映了设计良好的纵向干预研究,适合于决策.
    在这篇系统综述中,UFSM与增加的膳食参与有关,出勤率没有或略有改善,肥胖患病率和中止率降低;午餐参与的证据确定性适中,其他结局的证据确定性较低或非常低.研究没有报告几个重要的结果,如饮食质量和粮食安全,这表明需要更多高质量的研究,包括与政策相关的指标。
    UNASSIGNED: The White House National Strategy on Hunger, Nutrition, and Health included expanding free school meals to all students, regardless of income, which has sparked debate in the United States.
    UNASSIGNED: To assess the association between universal free school meals (UFSMs) and school and student outcomes in the United States.
    UNASSIGNED: An expert panel-informed protocol was developed to evaluate intervention or cohort studies comparing UFSM programs, such as the Community Eligibility Provision (CEP), with non-UFSM programs in US schools from August 2012 (excluding 2020-2021 due to the COVID-19 pandemic) in peer-reviewed publications or government reports. Outcomes included meal participation rates, attendance, dietary intake and quality, food waste, economic impact, food insecurity, anthropometrics, disciplinary actions, stigma, and shaming. A search of Medline, Econlit, Business Source Ultimate, ERIC, Agricola, Cab Abstracts, and CINAHL was performed in April 2024. Two researchers screened articles for inclusion, extracted data, and assessed risk of bias, using the Risk of Bias in Nonrandomized Studies of Interventions tool, for each included study. Grading of Recommendations, Assessment, Development, and Evaluations was used to assess the certainty of evidence for each outcome.
    UNASSIGNED: The search identified 2784 records, with 6 studies included, representing more than 11 000 elementary, middle, and high schools. Nonrandomized intervention studies performed difference-in-difference or rate ratio analysis to investigate CEP participation rates, attendance, anthropometrics, and/or suspensions. CEP was associated with increased lunch (3 studies; moderate certainty) and breakfast (1 study; very low certainty) participation. School attendance was unchanged or improved in schools with CEP compared with schools without UFSM (2 studies; low certainty). CEP was associated with lower obesity prevalence (1 study; very low certainty) and fewer suspensions (1 study; very low certainty). Reasons for downgrading the certainty ratings included indirectness (data not fully representative of the United States) and inconsistency (small number of studies limiting ability to assess consistency). Despite the limitations, the evidence reflected well-designed longitudinal intervention studies appropriate for decision-making.
    UNASSIGNED: In this systematic review, UFSMs were associated with increased meal participation, no or slight improvements in attendance, and decreased obesity prevalence and suspension rates; certainty of evidence was moderate for lunch participation and low or very low for other outcomes. Studies did not report several important outcomes, such as diet quality and food security, suggesting the need for more high-quality research encompassing policy-relevant indicators.

    自2011年启动以来,已有59个国家的政府使用世界银行的“促进更好教育成果的系统方法”(SABER)政策工具来设计其基于学校的国家健康和营养计划。该工具指导各国政府对照国际基准自我评估其教育系统政策,并确定可采取行动的优先事项,以加强国家计划。撒哈拉以南非洲49个国家中有32个(65%)进行了SABER审查,在全球范围内,68%的低收入国家和54%的中低收入国家采用了这种方法。对51项可比的SABER学校供餐调查的分析表明,建立国家学校供餐框架更长的国家在其他政策领域也往往更先进。反之亦然。SABER的评论一致确定,也许可以预见,最薄弱的政策领域与方案设计有关,实施和财政空间。此分析还发现,该工具在跟踪几个时间点实施的政策演变方面具有附加价值,并表明随着国家计划的成熟,政策领域变得更加先进。该工具的这些好处与2021年共同创建全球学校膳食联盟的98个国家特别相关。联盟成员国的具体目标是扩大覆盖面,并支持受COVID-19大流行期间学校关闭影响的学童和青少年的福祉。SABER工具具有证明的潜力,加快和跟踪学校膳食政策的变化,因为它以前曾被撒哈拉以南非洲74%(31/42)的低收入和中低收入国家使用,是这些国家政治经济中已经被接受的要素,因此有可能迅速部署。
    Since its launch in 2011, 59 governments have used the World Bank\'s Systems Approach for Better Education Results (SABER) policy tool to design their national school-based health and nutrition programs. This tool guides governments to self-evaluate their education system policies against international benchmarks and identify actionable priorities to strengthen national programs. Thirty-two of the 49 countries in sub-Saharan Africa (65%) have undertaken a SABER review, and globally the approach has been adopted by 68% of the world\'s low-income countries and 54% of lower-middle-income countries. Analysis of 51 comparable SABER School Feeding surveys suggests that countries with longer established national school meals frameworks tend also to be more advanced in other policy areas, and vice versa. The SABER reviews consistently identify, perhaps predictably, that the weakest policy areas relate to program design, implementation and fiscal space. This analysis also found that the tool had an additional value in tracking the evolution of policies when implemented over several time points, and showed that policy areas become more advanced as national programs mature. These benefits of the tool are particularly relevant to the 98 countries that co-created the global School Meals Coalition in 2021. The Coalition member countries have the specific goal of enhancing coverage and support for the well-being of schoolchildren and adolescents affected by the school closures during the COVID-19 pandemic. The SABER tool has the demonstrated potential to implement, accelerate and track changes in school meals policy and, since it has been previously used by 74% (31/42) of low- and lower-middle-income countries in sub-Saharan Africa, is an already accepted element of the political economies of those countries and so has the potential to be deployed rapidly.

    近年来,英国学校的蔬菜供应有所增加;然而,孩子们仍然很少吃给他们吃的蔬菜。两项实验性试点和可行性研究实施了蔬菜优先(研究1)加体验式学习(研究2)的方法,以增加儿童在学校午餐时间(分别为3-5岁和4-7岁)的蔬菜消费量。两项研究都涉及在剩下的饭前10分钟食用蔬菜,通过体验式学习技术(重复曝光,“蔬菜优先”餐盘,蔬菜歌曲,视频,和营养教育)补充研究2中的蔬菜服务。研究1(n=38)发现,蔬菜首先食用,与所有食物一起食用相比,蔬菜摄入量增加12g。研究2(n=69)发现,蔬菜消费取决于个别学校。蔬菜摄入量低的学校在干预周期间显示消费量增加,而蔬菜摄入量高的学校几乎没有变化。发现干预措施的可接受性对参与的儿童和学校有利,尽管担心先上蔬菜的时间和与COVID相关的环境限制降低了一些学校的可行性。通过在反复接触期间提供更多种类的蔬菜以减少单调,也可以改善儿童的参与度。未来的研究应该使用共同设计方法来设计干预措施,包括学校,以适应他们的环境。同时也用系统方法解决了这个问题。注重儿童通过经验学习的干预措施需要考虑特定的学校环境,包括课程需求,可用于学校午餐的资源(包括时间和空间),提供食物,老师和家长的支持,以及围绕饮食的文化(例如鼓励,吃饭的压力,午餐时间与游戏时间竞争)。联合系统方法可以提高学校膳食中蔬菜的供应和吸收。
    Vegetable provision at schools in the UK has increased over recent years; however children still eat few of the vegetables that are served to them. Two experimental pilot and feasibility studies implemented a vegetables-served-first (study 1) plus experiential learning (study 2) approach to increase children\'s (3-5 years and 4-7 years respectively) vegetable consumption at school lunchtimes. Both studies involved vegetables-served-first 10-min before the rest of the meal, with experiential learning techniques (repeated exposure, \"veg-first\" dinner plates, vegetable songs, videos, and nutrition education) complementing the vegetable service in study 2. Study 1 (n = 38) found that vegetables-served-first, compared with serving all foods together, increased vegetable intake by ∼12 g. Study 2 (n = 69) found that vegetable consumption depended on individual schools. Schools where vegetable intake was low showed increases in consumption during intervention weeks, whereas schools with high vegetable intake showed little change. Acceptability of interventions was found to be good for children and schools that participated, although concerns about time to serve vegetables first and COVID-related environmental restrictions reduced feasibility for some schools. Child engagement could also be improved by offering a wider variety of vegetables during repeated exposure to reduce monotony. Future research should design interventions using co-design methods including schools to suit their context best, whilst also addressing the problem with a systems approach. Interventions which focus on child learning through experience need to take account of specific school environments including curricular needs, resources available for school lunch (including both time and space), provision of food, support from teachers and parents, and the culture around eating (e.g. encouragement, pressure to eat, lunchtime competing with playtime). Joined-up systems approaches could enhance both provision and uptake of vegetables at school meals.

    背景:大学校园提供了广阔的食物环境,这可能导致大学生过度能量摄入和体重增加的风险增加。所有你可以吃的自助餐厅经常让学生吃到超美味的食物(HPF),这可能会促进暴饮暴食。这项研究旨在检查大学自助餐厅中HPF的可用性,并检查大学生进餐时的HPF摄入量。
    方法:分析了中西部一所大学公开提供的自助餐厅菜单数据,包括25餐。为了确定自助餐厅餐中HPF的可用性,Fazzino等人对HPF的标准化定义。(2019)使用,它指定了可诱导超适口性的定量阈值的适口性诱导营养素的组合。在过去24小时内在自助餐厅吃饭的参与者(N=225)会收到相应自助餐厅餐的所有菜单项的列表,并自我报告所有消耗的物品。
    结果:平均而言,每餐可获得的总食物中有40%(SD=1.4)是HPF,68%(SD=3.6)的脂肪和钠升高的项目。关于学生中HPF的摄入量,消耗的食物中约有64%(SD=31.4)是HPF,消耗的物品中,有51%(SD=32.3)的脂肪和钠升高。
    结论:研究结果表明,大学生可能会在可以吃的大学自助餐厅环境中经常接触HPF,学生可能会食用主要由HPF组成的自助餐。
    BACKGROUND: College campuses provide an expansive food environment, which may contribute to elevated risk of excess energy intake and weight gain among college students. All-you-can-eat style cafeterias often expose students to hyper-palatable foods (HPF), which may promote overeating. This study aimed to examine the availability of HPF in an all-you-can-eat college cafeteria, and to examine HPF intake during meals among undergraduates.
    METHODS: Publicly available cafeteria menu data from a Midwestern university were analyzed and included 25 meals. To determine the availability of HPF within the cafeteria meals, the standardized definition of HPF by Fazzino et al. (2019) was used, which specifies combinations of palatability-inducing nutrients at quantitative thresholds that may induce hyper-palatability. Participants (N = 225) who ate in the cafeteria in the past 24 h were presented with a list of all menu items for their corresponding cafeteria meal, and self-reported all items consumed.
    RESULTS: On average, 40 % (SD = 1.4) of total food items available per meal were HPF, with 68 % (SD = 3.6) of items with elevated fat and sodium. Regarding intake of HPF among students, approximately 64 % (SD = 31.4) of foods consumed were HPF, and 51 % (SD = 32.3) of items consumed had elevated fat and sodium.
    CONCLUSIONS: Findings indicated that college students may be regularly exposed to HPF in all-you-can-eat college cafeteria environments, and that students may consume cafeteria meals that are primarily comprised of HPF.

    学校午餐对儿童的健康成长起着重要的作用。先前的调查显示,学校午餐存在许多问题,包括膳食结构不合理和微量营养素不足。本研究旨在评估南京市中小学午餐的膳食结构和营养质量。采用分层整群随机抽样的方法,选取南京市12个区44所供应午餐的学校,每个地区有两所小学和两所中学。选择了24所小学和20所中学。采用Mann-WhitneyU检验探讨影响因素。调查结果显示,学校午餐中牛奶和水果严重短缺;鸡蛋供应,鱼,虾,贝类不到建议数量的一半;畜禽供应量超过建议水平四倍以上。能量和营养摄入次优。提供能源,碳水化合物,维生素(A,B1、B2和C),钙,城市小学的铁含量明显高于非城市小学。与非城市中学相比,城市中学的营养素含量明显更高。这表明粮食供应受到区域经济的影响。因此,迫切需要提高午餐质量,特别关注非城市地区的人。
    School lunch plays an important role in children\'s healthy growth. Previous investigations revealed many problems with school lunches, including unreasonable dietary structure and insufficient micronutrients. This study aimed to assess the dietary structure and nutritional quality of lunches in Nanjing primary and middle schools. A stratified cluster random sampling method was used to select 44 schools that supply lunch in 12 districts in Nanjing, with two primary and two middle schools in each district. Twenty-four primary and twenty middle schools were selected. The Mann-Whitney U test was used to explore the influencing factors. Findings revealed a serious shortage of milk and fruit in school lunches; supply of eggs, fish, shrimp, and shellfish was less than half of the recommended quantity; livestock and poultry supply exceeded the recommended level by over four times. Energy and nutrition intake were suboptimal. Provision of energy, carbohydrates, vitamins (A, B1, B2, and C), calcium, and iron in urban primary schools was significantly higher than that in non-urban primary schools. The same pattern of significantly higher nutrients was equally seen in urban middle schools compared with non-urban middle schools, indicating that food supply was affected by regional economies. Therefore, it is urgent to improve the quality of lunches, with a particular focus on those in non-urban areas.
