A cross-sectional study to determine the energy density and nutritional quality of primary-school children's lunchboxes

Are Cooked Nutritious School Lunches Associated with Improved Attendance? Findings from the 2022-2023 Tasmanian School Lunch Project

Background/Objectives: During 2022-2023, the School Lunch Project (SLP) provided free nutritious cooked lunches 1-4 days per week to Kinder to Grade 10 students attending 30 schools in areas of high disadvantage in Tasmania, Australia. This analysis examined if the SLP was associated with student attendance. Methods: Staff (teachers, support staff, and principals) from 12 schools completed an online survey and/or participated in focus groups/interviews. Government-held, objectively measured, grade-level attendance data were provided for 17 SLP and 11 matched comparison schools for 2018-2023. Linear mixed models compared attendance on school lunch and non-school lunch days in SLP schools. Difference-in-difference regression compared attendance between SLP and comparison schools. Qualitative data were analysed thematically. Results: Sixty-five staff completed surveys, where 22% reported that increased attendance was a benefit of the SLP. Similar findings were observed in the staff focus groups/interviews (N = 51). Mean attendance was similar on school lunch and non-school lunch days among the SLP schools during 2022 (difference: 0.04, 95% CI: -0.5, 0.6) and 2023 (difference 0.1, 95% CI: -0.2, 0.4) and similar between SLP and comparison schools (average treatment effect in the treated: 1.2, 95% CI: -0.7, 3.0). Conclusions: The SLP was perceived by some staff to improve attendance but was not associated with objectively measured attendance examined at the grade level.

Parents face several barriers in providing a healthy school lunch for their primary school children: A survey of Victorian (Australian) parents

ISSUE ADDRESSED

This paper aims to explore Victoria parents' perceptions of their current practices and barriers in providing school lunches for their primary school children.

METHODS

Respondents were asked via an online survey about their lunch provision practices, perceptions of the healthiness of school lunches, and barriers to providing healthy school lunches. Data were analysed using different statistical techniques: Chi-square test, Spearman correlation analysis, Mann-Whitney U test, and Kruskal-Wallis test.

RESULTS

In total, 359 respondents completed the survey. Most respondents (84%) reported their child takes a home-packed lunch to school every day. Most respondents provided fruits (94%), vegetables (57%), and sandwiches (54%) every day for school lunches, whilst other core food items such as milk, meats, and legumes were provided less frequently. A substantial proportion of respondents provided some discretionary food items frequently (e.g., the proportion of respondents providing selected discretionary food items daily or 3-4 times/week: salty crackers-50%, sweet cookies/biscuits-40%, chips-20%). Respondents strongly agreed or agreed with several barriers; examples include not packing certain foods due to food spoilage concerns (50%) (school-related), the allocated time at their child's school is not enough to eat and enjoy school lunch (48%) (school-related), need more meal ideas (61%) (parent-related), healthy foods take more time to prepare (51%) (parent-related), and children request easy-to-eat food for school lunches (50%) (child-related). Core food score (an indicator of frequency of preparing/packing core food) was negatively correlated with parent-related and child-related barrier scores, whilst discretionary food score (an indicator of frequency of preparing/packing discretionary food) was positively correlated with these barrier scores.

CONCLUSIONS

Overall, home-packed lunches remain the main option in primary schools in Victoria, and parents face several challenges in providing healthy lunches for their primary school children. SO WHAT?: The findings suggest the need for strategies from school leaders, education authorities, and policymakers to improve the quality of lunch content and address the barriers faced by parents.

Unpacking the cost of the lunchbox for Australian families: a secondary analysis

Ninety per cent of Australian school children bring a home-packed lunch to school, with 44% of the food consumed during school hours being unhealthy. Among other factors, cost is a key consideration for food provision; however, the costs to Australian families are not well understood. Therefore, we aimed to determine what families are currently paying for school lunchboxes in Australian primary schools and to examine associations between food costs and socio-demographic factors with dietary quality. An audit of local retail outlets was used to determine the food costs of lunchbox contents. Costs (AUD) were adjusted for inflation as of early 2023. The lunchboxes of 1026 children aged 4-12 years at 12 Catholic primary schools in New South Wales, Australia, were assessed at the start of the day, using photography assessment methods and a validated School Food Checklist. The mean cost of lunchbox contents was $4.48 AUD (SD 1.53), containing a mean energy of 2699 kJ (SD 859), with 37.3% (SD 23.9) of energy sourced from unhealthy foods. Multiple linear regression analyses found that the strongest predictors of higher lunchbox cost (P < 0.05) were a higher proportion of energy from unhealthy foods (B = 0.016) and lower Socio-Economic Indexes for Areas (B = -0.178), when controlling for child socio-demographics. The results indicated that lunchbox food costs to Australian families are comparable to alternative school food service models in Australia and internationally. Results demonstrate the cost of food is not the only barrier to providing a healthy school lunchbox. Demonstrating a need for cost-considerate systematic interventions addressing food provision challenges and socio-economic disparities faced by families.

Parental support for free school lunches in Australian primary schools: associated factors and perceived barriers

OBJECTIVE

(1) To explore the feasibility of such programmes in Australia, this study examined parents' views on free school lunch provision. (2) To examine the associations between parents' demographic and personal characteristics and their support for free universal school lunches.

DESIGN

An online cross-sectional survey of parents.

SETTING

Australia, April 2021.

PARTICIPANTS

Seven hundred and eighty-seven parents took the survey. They had a mean age of 40. The respondents were predominantly female (95 %) and had a university degree (72 %).

RESULTS

Fifty-three percentage of the respondents agreed that all students should have access to healthy and well-balanced, free school lunches. Parents were concerned about healthiness, catering, allergies and cost of school-provided school lunches. Ethnic background, universalism values and education levels were significantly associated with support for free school lunch provision. Non-native English-speaking parents were almost three times more likely to support free universal lunches in primary schools than their native English-speaking counterparts. Parents with higher universalism-concern values were more likely to endorse free lunches in primary school. However, the level of education was negatively associated with parents' support for free school lunches.

CONCLUSIONS

The survey results highlight the complexity of parental views on free school lunch provision. Parents' concerns regarding lunches should be considered in developing school lunch programmes that meet the needs and preferences of diverse communities. These findings can be used to guide future primary school lunch provision initiatives.

New models to support parents to pack healthy lunchboxes: Parents acceptability, feasibility, appropriateness, and adoption of the SWAP IT m-Health program

OBJECTIVES

This report aims to evaluate the acceptability, appropriateness, feasibility, and adoption of a healthy lunchbox program (SWAP IT), from the parent perspective.

METHODS

SWAP IT is an mobile health (m-Health) program aimed to support parents in swapping out discretionary foods for healthier alternatives. Following receipt of the program, parents completed validated scales assessing the Acceptability (AIM), Intervention Appropriateness (IAM), and Feasibility (FIM) via a computer-assisted telephone interview (CATI). Parents were asked about their awareness of strategies in SWAP IT and whether the program supported them to make lunchbox swaps from discretionary to everyday foods.

RESULTS

Of the 679 parents who consented, 413 completed the CATI (61% response rate). Parent's mean AIM score (out of a total score of 5) was 4.22 (SD 0.48); FIM score was 4.27 (SD 0.54); and IAM score was 4.24 (SD 0.54). Most parents reported receiving the lunchbox messages (54%), with 45% reporting opening all 10 messages and 64% of parents reporting the program helped swap out discretionary foods.

CONCLUSION

The m-Health lunchbox program, SWAP IT, is highly acceptable, easy to adopt, appropriate, and feasible to parents.

IMPLICATIONS TO PUBLIC HEALTH

Not only is SWAP IT effective, but favourable implementation factors highlight the potential scalability of the program in improving child nutrition.

School lunchboxes as an opportunity for health and environmental considerations: a scoping review

Very little research has focussed on children's school lunchboxes from both a health and environment standpoint. This scoping review explores studies that considered children's lunchbox food consumption trends at school and the environmental impacts of lunchbox contents. We conducted a scoping review of peer-reviewed literature with a focus on lunchboxes of children in preschool or primary school settings that contained food packed from home, through the lens of food and nutrition in combination with environmental outcomes-particularly food and/or packaging waste. The review included 10 studies, with articles from Australia, USA, Spain, New Zealand and the UK. Half of them were intervention studies aiming to shift knowledge levels and attitudes of teachers, parents and children with regard to reducing packaged food choices and food waste, and improving dietary habits. Acknowledging the complexity of lunchbox packing and consumption practices, this review recommends the consideration of socio-ecological influences on children's health and sustainability behaviour, and mobilizing their pro-environmental agency.

An mHealth Intervention to Reduce the Packing of Discretionary Foods in Children's Lunch Boxes in Early Childhood Education and Care Services: Cluster Randomized Controlled Trial

Background

Interventions in early childhood education and care (ECEC) services have the potential to improve children’s diet at the population level.

Objective

This study aims to test the efficacy of a mobile health intervention in ECEC services to reduce parent packing of foods high in saturated fat, sugar, and sodium (discretionary foods) in children’s (aged 3-6 years) lunch boxes.

Methods

A cluster randomized controlled trial was undertaken with 355 parent and child dyads recruited by phone and in person from 17 ECEC services (8 [47%] intervention and 9 [53%] control services). Parents in the intervention group received a 10-week fully automated program targeting barriers to packing healthy lunch boxes delivered via an existing service communication app. The program included weekly push notifications, within-app messages, and links to further resources, including websites and videos. The control group did not receive any intervention. The primary outcomes were kilojoules from discretionary foods and associated nutrients (saturated fat, free sugars, and sodium) packed in children’s lunch boxes. Secondary outcomes included consumption of kilojoules from discretionary foods and related nutrients and the packing and consumption of serves of discretionary foods and core food groups. Photography and weights of foods in children’s lunch boxes were recorded by trained researchers before and after the trial to assess primary and secondary outcomes. Outcome assessors were blinded to service allocation. Feasibility, appropriateness, and acceptability were assessed via an ECEC service manager survey and a parent web-based survey. Use of the app was assessed via app analytics.

Results

Data on packed lunch box contents were collected for 88.8% (355/400) of consenting children at baseline and 84.3% (337/400) of children after the intervention. There was no significant difference between groups in kilojoule from discretionary foods packed (77.84 kJ, 95% CI −163.49 to 319.18; P=.53) or the other primary or secondary outcomes. The per-protocol analysis, including only data from children of parents who downloaded the app, also did not find any statistically significant change in primary (−1.98 kJ, 95% CI −343.87 to 339.90; P=.86) or secondary outcomes. Approximately 61.8% (102/165) of parents in the intervention group downloaded the app, and the mean service viewing rate of weekly within-app messages was 26% (SD 14.9). Parents who responded to the survey and participating services agreed that it was appropriate to receive lunch box information via the app (40/50, 80% and 6/8, 75%, respectively).

Conclusions

The intervention was unable to demonstrate an impact on kilojoules or associated nutrients from discretionary foods packed in children’s lunch boxes. Low app downloads and program message views indicate a need to explore how to improve factors related to implementation before further testing similar mobile health interventions in this setting.

Foods and beverages provided in out of school hours care services: an observational study

Introduction

Out of school hours care (OSHC) is a fast-growing childcare setting in Australia, however the types of foods and beverages offered are relatively unknown. This study describes the food and beverages offered and investigates sector-level and setting-level factors which may impact OSHC in meeting the Australian Dietary Guidelines (ADG).

Methods

This cross-sectional, observational study was conducted in 89 OSHC services (between 2018 and 2019). Food and beverages offered, kitchen facilities and menus were captured via direct observation. Foods were categorised into five food groups or discretionary foods, based on the ADG, and frequencies determined. Short interviews with OSHC directors ascertained healthy eating policies, staff training, food quality assessment methods and food budgets. Fisher’s exact test explored the influence of sector-level and setting-level factors on food provision behaviours.

Results

Discretionary foods (1.5 ± 0.68) were offered more frequently than vegetables (0.82 ± 0.80) (p < .001), dairy (0.97 ± 0.81) (p = .013) and lean meats (0.22 ± 0.54) (p < .001). OSHC associated with long day care and reported using valid food quality assessment methods offered more lean meats (p= .002, and p= .004). Larger organisations offered more vegetables (p = .015) and discretionary foods (p= .007). Menus with clearly worded instructions to provide fruits and vegetables daily offered more fruit (p= .009), vegetables (p < .001) and whole grains (p= .003). No other sector or setting-level factors were associated with services aligning with the ADG.

Conclusion

Future interventions could benefit from trialling menu planning training and tools to assist OSHC services in NSW meet the ADG requirements.

The food and nutrient intake of 5- to 12-year-old Australian children during school hours: a secondary analysis of the 2011-2012 National Nutrition and Physical Activity Survey

OBJECTIVE

School food intake of Australian children is not comprehensively described in literature, with limited temporal, nationally representative data. Greater understanding of intake at school can inform school-based nutrition promotion. This study aimed to describe the dietary intake of primary-aged children during school hours and its contribution to daily intake.

DESIGN

This secondary analysis used nationally representative, cross-sectional data from the 2011 to 2012 National Nutrition and Physical Activity Survey. Dietary intake was assessed using validated 24-h dietary recalls on school days. Descriptive statistics were undertaken to determine energy, nutrients, food groups and food products consumed during school hours, as well as their contributions to total daily intake. Associations between school food intake and socio-demographic characteristics were explored.

SETTING

Australia.

PARTICIPANTS

Seven hundred and ninety-five children aged 5-12 years.

RESULTS

Children consumed 37 % of their daily energy and 31-43 % of select nutrient intake during school hours, with discretionary choices contributing 44 % of school energy intake. Most children consumed less than one serve of vegetables, meat and alternatives or milk and alternatives during school hours. Commonly consumed products were discretionary choices (34 %, including biscuits, processed meat), bread (17 %) and fruit (12 %). There were limited associations with socio-economic position variables, apart from child age.

CONCLUSIONS

Children's diets were not aligned with national recommendations, with school food characterised by high intake of discretionary choices. These findings are consistent with previous Australian evidence and support transformation of the Australian school food system to better align school food consumption with recommendations.

Enough time for lunch? The duration and governance of lunch eating times in Australian primary schools: A mixed-methods study

Developing healthy eating behaviours is important to assist children in maintaining good health and decrease the risk of chronic health conditions. Recent nutrition promotion efforts in Australian primary schools have mainly focused on canteen guideline compliance and obesity prevention interventions. The aim of this study was to investigate the primary school food environment, specifically, allocated lunch eating duration and the governance of children's lunch breaks. Parents (n = 402) and teachers (n = 123) were asked via an online survey, about school allocated lunch eating duration and its adequacy. Respondents were asked about the supervision, monitoring and feedback of children's lunches, as well as how they felt about these practices. Parents (n = 308) and teachers (n = 102) also responded to the open-ended question "What could be done to improve the school food environment at your school?". Ten minutes was the allocated lunch eating duration reported by most parents and teachers and 58% of those parents and 30% of those teachers rated this as inadequate. Increasing the allocated lunch eating duration was frequently cited as a way to improve the school food environment. A similar proportion of parents and teachers agreed with teachers monitoring food intake, not providing feedback on food brought to school, and that parents should decide what children eat. More parents (44%) than teachers (23%) believed that teachers should eat their own lunch with the children. These findings provide an insight into the primary school lunch environment and the views of two key stakeholder groups. School food policies should consider these findings in future revisions, particularly with regards to eating times.

Enhancing the potential effects of text messages delivered via an m-health intervention to improve packing of healthy school lunchboxes

OBJECTIVE

The aim of the study was to assess the impact of different lunchbox messages on parents' intention to pack a healthy lunchbox.

DESIGN

This study employed an experimental design.

SETTING

A series of messages were developed to align with the six constructs of the Health Belief Model. Messages were also developed that were (and were not) personalised and varied based on the source of the information provided (university, school, dietitian and health promotion service). During a telephone survey, participants were read the content of each message and asked about their intention to pack a healthy lunchbox.

PARTICIPANTS

Parents of primary school-aged children were randomised to receive different messages to encourage the packing of healthy lunchboxes.

RESULTS

The study was completed by 511 parents. Linear mixed regression analyses identified significant differences (P < 0·05) in intention scores between variant messages targeting the same behavioural constructs for 'susceptibility', 'severity', 'benefits' and 'barriers' but not 'cues to action' or 'self-efficacy'. The highest mean behavioural intention score was for 'benefits', whilst the lowest mean score was for 'barriers'. There were no significant differences in intention scores of parents receiving messages from a dietitian, university, health promotion team or school (P = 0·37). Intention scores did not differ in which messages were personalised based on child's name (P = 0·84) or grade level (P = 0·54).

CONCLUSIONS

The findings suggest that messages that focus on the benefits of packing healthy lunchboxes may be particularly useful in improving intentions of parents to pack healthy foods for their children to consume at school.

A Multicomponent mHealth-Based Intervention (SWAP IT) to Decrease the Consumption of Discretionary Foods Packed in School Lunchboxes: Type I Effectiveness-Implementation Hybrid Cluster Randomized Controlled Trial

Background

There is significant opportunity to improve the nutritional quality of foods packed in children’s school lunchboxes. Interventions that are effective and scalable targeting the school and home environment are therefore warranted.

Objective

This study aimed to assess the effectiveness of a multicomponent, mobile health–based intervention, SWAP IT, in reducing the energy contribution of discretionary (ie, less healthy) foods and drinks packed for children to consume at school.

Methods

A type I effectiveness–implementation hybrid cluster randomized controlled trial was conducted in 32 primary schools located across 3 local health districts in New South Wales, Australia, to compare the effects of a 6-month intervention targeting foods packed in children’s lunchboxes with those of a usual care control. Primary schools were eligible if they were not participating in other nutrition studies and used the required school communication app. The Behaviour Change Wheel was used to co-design the multicomponent SWAP IT intervention, which consisted of the following: school lunchbox nutrition guidelines, curriculum lessons, information pushed to parents digitally via an existing school communication app, and additional parent resources to address common barriers to packing healthy lunchboxes. The primary outcome, mean energy (kilojoules) content of discretionary lunchbox foods and drinks packed in lunchboxes, was measured via observation using a validated school food checklist at baseline (May 2019) and at 6-month follow-up (October 2019). Additional secondary outcomes included mean lunchbox energy from discretionary foods consumed, mean total lunchbox energy packed and consumed, mean energy content of core lunchbox foods packed and consumed, and percentage of lunchbox energy from discretionary and core foods, all of which were also measured via observation using a validated school food checklist. Measures of school engagement, consumption of discretionary foods outside of school hours, and lunchbox cost were also collected at baseline and at 6-month follow-up. Data were analyzed via hierarchical linear regression models, with controlling for clustering, socioeconomic status, and remoteness.

Results

A total of 3022 (3022/7212, 41.90%) students consented to participate in the evaluation (mean age 7.8 years; 1487/3022, 49.22% girls). There were significant reductions between the intervention and control groups in the primary trial outcome, mean energy (kilojoules) content of discretionary foods packed in lunchboxes (–117.26 kJ; 95% CI –195.59 to –39.83; P=.003). Relative to the control, the intervention also significantly reduced secondary outcomes regarding the mean total lunchbox energy (kilojoules) packed (–88.38 kJ; 95% CI –172.84 to –3.92; P=.04) and consumed (–117.17 kJ; 95% CI –233.72 to –0.62; P=.05). There was no significant difference between groups in measures of student engagement, consumption of discretionary foods outside of school hours, or cost of foods packed in children’s lunchboxes.

Conclusions

The SWAP IT intervention was effective in reducing the energy content of foods packed for and consumed by primary school–aged children at school. Dissemination of the SWAP IT program at a population level has the potential to influence a significant proportion of primary school–aged children, impacting weight status and associated health care costs.

Greater and More Focused Measures Are Needed to Tackle Diabetes and Obesity Epidemics in the Nations of the Gulf Cooperation Council

Beyond the suffering of the affected subjects, type 2 diabetes (T2D) and obesity epidemics gripping the Gulf Cooperation Council (GCC) states are expected to seriously jeopardize these nations' economies and development due to productivity losses. Available data show that healthcare budgets in GCC nations are under tremendous pressure because of diabetes- and obesity-linked comorbidities. Furthermore, T2D, once an over-forties disease, risks becoming a whole-adult-life condition because of obesity-associated early-onset T2D and prediabetes. The incidence of T2D is set to worsen unless efficient actions are taken to fight obesity and prevent the conversion of prediabetes to T2D. There is a consensus that the concomitant increase in obesity rates drives T2D rates upward. Fighting obesity at all levels should, therefore, take center stage for the GCC nations. The battle against obesity and T2D is a long-term and complex one. Therefore, only through concerted efforts between several public and private actors, including health, economic, and urbanization agencies, food producers and retailers, schools, families, youth organizations, sports clubs, and voluntary organizations, can this battle be won. The present review tries to assess the current status of diabetes and obesity epidemics in the GCC context and take stock of some of the policies and initiatives that have been, or need to be, implemented to address their growing burden.

Stakeholder Generated Ideas for Alternative School Food Provision Models in Australia Using the Nominal Group Technique

Good nutrition is important for children's learning, growth, and development, yet food intake during school hours does not align with recommendations. In Australia, most school children currently bring a packed lunch from home, but what if there was a different way? This project aimed to engage a diverse range of stakeholders to (1) generate, refine and prioritize ideas for novel models of food provision to Australian children within school hours, and (2) to determine and rank the potential barriers and facilitators to changing the school food provision system. This study used nominal group technique virtual workshops-three idea generation workshops (n = 21 participants) and one consensus workshop (n = 11 participants). School lunch prepared onsite was the top ranked food provision model option based on impact and achievability. Potential barriers (n = 26) and facilitators (n = 28) to changing the school food system were generated. The top ranked barrier and facilitator related to government support. This study highlights that there is an opportunity to explore partnerships and utilize existing skills and infrastructure to introduce a universal school-provided lunch model in Australia. The next steps should focus on building the business case capturing the social value of investing in school lunches, including considering parent-paid and subsidized options.

Protocol for an effectiveness- implementation hybrid trial to assess the effectiveness and cost-effectiveness of an m-health intervention to decrease the consumption of discretionary foods packed in school lunchboxes: the 'SWAP IT' trial

BACKGROUND

At a population level, small reductions in energy intake have the potential to contribute to a reduction in the prevalence of childhood obesity. In many school systems, there is the potential to achieve a reduction in energy intake through modest improvements in foods packed in children's school lunchboxes. This study will assess the effectiveness and cost-effectiveness of a multi-component intervention that uses an existing school-based communication application to reduce the kilojoule content from discretionary foods and drinks consumed by children from school lunchboxes whilst at school.

METHODS

A Type I hybrid effectiveness-implementation cluster randomised controlled trial will be conducted in up to 36 primary schools in the Hunter New England, Central Coast and Mid North Coast regions of New South Wales, Australia. Designed using the Behaviour Change Wheel, schools will be randomly allocated to receive either a 5-month (1.5 school terms) multi-component intervention that includes: 1) school lunchbox nutrition guidelines; 2) curriculum lessons; 3) information pushed to parents via an existing school-based communication application and 4) additional parent resources to address common barriers to packing healthy lunchboxes or a control arm (standard school practices). The study will assess both child level dietary outcomes and school-level implementation outcomes. The primary trial outcome, mean energy (kJ) content of discretionary lunchbox foods packed in children's lunchboxes, will be assessed at baseline and immediately post intervention (5 months or 1.5 school terms). Analyses will be performed using intention to treat principles, assessing differences between groups via hierarchical linear regression models.

DISCUSSION

This study will be the first fully powered randomised controlled trial internationally to examine the impact of an m-health intervention to reduce the mean energy from discretionary food and drinks packed in the school lunchbox. The intervention has been designed with scalability in mind and will address an important evidence gap which, if shown to be effective, has the potential to be applied at a population level.
