A healthy diet is important for the physical and mental well-being of children. The WHO(1) states that the establishment of healthy eating behaviours and optimal nutrition in children decreases the risk of obesity and cardiovascular disease (CVD), supports healthy adulthood and ageing and strengthens learning potential. Dietary risk factors are a leading global public health risk, contributing to 11 million deaths in 2017(Reference Afshin, Sur and Fay2). In Australia, poor dietary intake is the fourth highest risk factor contributing to death and disability combined(3).
During 2020–2021, 37 % of Australian children aged 2–17 years were not meeting the recommended guidelines for fruit intake, and 90 % were not meeting vegetable recommendations(4). Additionally, in the last comprehensive survey of diet in Australian children during 2011–2012, 38 % of children’s daily energy intake was reportedly from low-nutrient and energy-dense discretionary foods(5). With the dietary intake of Australian children falling short of national recommendations, every opportunity should be taken to promote good nutrition and healthy eating.
Out of School Hours Care (OSHC) has been identified as a priority setting for addressing poor dietary habits among Australian children(Reference Crowe, Probst and Norman6,Reference Crowe, Probst and Weaver7) . In Australia, OSHC offers supervision and care to children aged 5–12 years before and after school and during school holiday periods (vacation care). OSHC services are usually located on school grounds; however, some operate out of day care/pre-schools or community centres. They can either be run by the school or privately, often by local community organisations. With over 4600 OSHC services operating in Australia as of June 2022(8) and just under half a million children attending care on a regular basis(9), OSHC is a widely utilised setting. Food and beverages are usually provided by the service for the children to consume at breakfast (before school care), a snack at afternoon tea (after school care) and sometimes for meals during vacation care. Previous studies have observed the quality of snacks provided in the after school care environment, with US services often failing to meet nutrition policies and predominantly serving high-sugar options(Reference Beets, Weaver and Tilley10) and Australian services offering discretionary foods significantly more than vegetables and lean meats(Reference Crowe, Probst and Norman6). Discretionary foods are ‘not an essential or necessary part of healthy dietary patterns’ and are ‘high in kilojoules, saturated fat, added sugars and/or salt’(11).
Understanding the food environment is an important first step for developing meaningful nutrition programmes. Recent after school care intervention studies conducted in the USA have demonstrated a positive effect on services providing and children consuming healthy snacks(Reference Lee, Giles and Cradock12,Reference Beets, Weaver and Turner-McGrievy13) . School breakfast programmes in both Denmark and the USA have also resulted in children consuming healthier food options(Reference Christensen, Mikkelsen and Toft14,Reference Forrestal, Potamites and Guthrie15) . Despite these improvements to child eating habits from after school care and school breakfast programmes, limited research has observed the food environment within centre-based before school care. Additionally, Australia does not have a nationally funded school meal programme, with some charitable organisations offering school breakfast programmes on a voluntary basis(Reference Hill, Byrne and Wenden16). This is concerning as breakfast is considered important for the cognitive development and academic success of children(Reference Adolphus, Lawton and Dye17). Understanding the before school care food environment will help inform whether interventions within this setting are also needed and provide a more complete understanding of the food environment within the Australian OSHC sector.
Therefore, this study aimed to (1) describe the foods and beverages provided by OSHC services during before school care and (2) explore how service-level factors influence food provision.
Methods
Study design and setting
A cross-sectional observational study was conducted in before school care programmes located in two local health districts of New South Wales (NSW), Australia. The two districts contain a diversity of cultures, socio-economic areas and geographic density(18,19) . The University of Wollongong Human Research Ethics Committee approved the study (2019/ETH03798), and a detailed study protocol has been previously published(Reference Crowe, Probst and Norman20).
Participants
At the commencement of recruitment in November 2020, 267 OSHC providers listed/registered on the Australian Children’s Education and Care Quality Authority website were eligible to participate. Eligibility criteria included services that (a) operated between 06.00 to 09.00 before school; (b) were situated within the geographic bounds of Illawarra Shoalhaven or South Western Sydney Local Health Districts in NSW, Australia; (c) had more than five students enrolled per day; and (d) provided food to children in attendance. All eligible services meeting these criteria were contacted for recruitment via email. An individual service report summarising their findings and recommending improvements was offered as an incentive to participate. Written informed consent was obtained from each OSHC service director, and study information was shared with staff and parents of attending children at least 2 weeks prior to data collection. All staff and children attending the service were eligible to participate in the study, with an opt-out consent approach taken. Information sheets and opt-out consent forms are emailed to families by the service as well as being made available at sign-in areas. If a staff member or child (by their parent/guardian) opted out, they would be disregarded during food environment observations.
The sample size was determined from an unpublished pilot study conducted in the before school care setting(Reference Woods, Probst and Wardle21). As the data in this study were collected as part of a wider study looking at both healthy eating and physical activity in the OSHC setting, the sample size was calculated using physical activity data. This calculation resulted in a required sample of nine OSHC services for 5 % precision. The research team, however, had the capacity to service a larger sample size, and it was determined that up to thirty services could be recruited. Recruitment efforts ceased once this target was met.
Data collection
Services were visited on two unannounced, non-consecutive days by trained data collectors between March and June 2021. During this data collection period, services were operating normally; however, some had COVID-19 procedures in place which data collectors would need to follow during visits (e.g. signing in and sanitising hands on arrival). The University of Wollongong Human Research Ethics Committee also required a COVID-19 safety plan to be developed and followed during research. This included social distancing from children and staff during visits, wearing face masks and disinfecting all equipment between visits.
Study data were collected and managed using the Research Electronic Data Capture tool (REDCap)(Reference Harris, Taylor and Thielke22,Reference Harris, Taylor and Minor23) , including the REDCap Mobile Application, hosted at the University of Wollongong, Australia. Data collectors were trained by two of the authors (AW, RC) over a 2-d period. On the first day, participants engaged in theoretical training within a classroom setting, focusing on the study objectives and the tools for data collection. The second day involved an on-site training at a before school care service, during which data collectors had the opportunity to observe typical operations and gain hands-on experience with the data collection tools.
Food and beverage observation and categorisation
The types of food and beverages provided to children were recorded via direct observation by trained data collectors, following previously published protocols(Reference Crowe, Probst and Norman20). As the purpose of this study was to describe the types of food that before school care services were offering, data were collected on food provision rather than child food consumption. Data were entered by data collectors into a food audit tool developed in REDCap for a family day care study by Kerr et al. (Reference Kerr, Kelly and Hammersley24) and based on a tool created by Kelly et al. (Reference Kelly, Hardy and Howlett25). Food was entered according to twelve categories: fruit, vegetables, dairy products, non-dairy product drinks, sweet snacks, savoury snacks, breakfast cereals, other grains and cereals, spreads and syrups, meat and alternatives, sauces and condiments and other foods. Photographs were taken of the food provided, as well as the packaging and nutrition labels where available.
Following data collection, the existing categories of the food audit tool were classified into the five food groups according to the Australian Dietary Guidelines: fruit, vegetables, dairy products, grains and lean meats and alternatives(11). Additional groups were added for unsaturated spreads and oils, discretionary foods and discretionary beverages to report foods/beverages that do not fall into the five food groups. Sub-categories of these food groups were added (see Table 1), and food groups were coded dichotomously as offered or not offered(Reference Crowe, Probst and Norman6). To account for the varying nutritional quality of breakfast cereals, additional sub-categories were added for < 15 g/100 g total sugar and ≥ 15 g–< 30 g/100 g total sugar as has been reported previously(Reference Fayet-Moore, McConnell and Cassettari26). Breakfast cereals with > 30 g/100 g total sugar (or > 35 g/100 g total sugar if they included added fruit) were classified as discretionary(27). The food classification was conducted by the lead author (AW) and guided by the Australian Health Survey food classification system(28) and the Australian Health Survey Discretionary Food List(29). As food had been previously entered by trained data collectors a priori into categories of the food audit tool, one researcher was deemed sufficient for this.

Food environment measures
The food environment was observed with the aid of two data collection tools. A food and beverage context form was completed at each visit and captured information on child and staff behaviours during breakfast, as well as details on how the meal environment was structured. Data were coded as observed or not observed for the categories: set time for breakfast; children able to serve themselves; restrictions on amount of food; water available as a drink; staff engaged in other duties during mealtime; staff off-task during mealtime (i.e. engaged on their phone); staff eating with children; staff promoting good nutrition (i.e. using positive language when discussing healthy food); staff discouraging good nutrition (i.e. using negative language when discussing healthy food or speaking favourably of unhealthy options); staff providing nutrition education; children preparing breakfast; children distributing food; and children cleaning away breakfast items. On this context form, kitchen facilities were also coded as limited (sink, refrigerator, limited bench space and food storage space), moderate (sink, refrigerator, microwave, moderate bench space and food storage space) or complete (sink, refrigerator, microwave, oven, stove, dishwasher, large bench space and food storage space). This tool and categorisation have been used previously in Australian after school care programmes(Reference Crowe, Probst and Norman6). Inter-observer reliability of this tool has not been tested; however, the tool and categories were covered extensively during data collection training.
A structured interview was conducted in person with each service director/coordinator to capture information on healthy eating policies and practices. The interview was guided by the validated Healthy Afterschool Activity and Nutrition Documentation (HAAND) tool (Reference Ajja, Beets and Huberty30) and took approximately 10 minutes. Responses were recorded in the HAAND tool using the REDCap Mobile Application during the interview. OSHC services are required to have a nutrition policy in Australia by law(31). A copy of this policy was requested in the interview. Policies were assessed for their level of detail and categorised as non-specific (limited detail, talks generally about foods aligning with the Australian Dietary Guidelines) or specific (measurable objectives, discusses serving certain food/beverages)(Reference Crowe, Probst and Norman6). Healthy eating practices captured during the interview included hours of annual staff training, collection of parent/child feedback on breakfast foods and assessment of menu food quality.
Participating OSHC services were also categorised according to their Index of Relative Socio-Economic Advantage and Disadvantage using the Socio-Economic Indexes for Areas published by the Australian Bureau of Statistics(32). Using the percentile ranking of the suburb the service was located in, services were classified into low, medium or high socio-economic tertiles.
Data analysis
SPSS software (version 24, IBM Corporation) was used to compute descriptive statistics for food and beverages observed to be offered across the two observation days. The mean number of Australian Dietary Guidelines’ five core food groups that were offered was also calculated by averaging the number of groups observed on each visit. Staff behaviours and responses from the interview (i.e. HAAND) were quantified and reported as a percentage of observations and services. Food data were skewed, so a χ 2 test of independence was used to compare food provision with before school care service characteristics, and a Fisher’s exact test was applied to determine if differences were significant at P< 0·05.
Results
Of the 267 eligible OSHC services, 31 provided consent. As a result of state-wide COVID-19 lockdowns in June 2021, data collection concluded early, and only twenty-five services participated. There were forty-nine observation visits conducted, with each service visited twice, except for one service with a single visit due to COVID-19 lockdowns. Twenty-one (84 %) services were operated by large organisations, and four (16 %) were independently run or part of a long day care service. Ten services (40 %) were in a low socio-economic suburb, six (24 %) in a medium socio-economic suburb and nine services (36 %) in a high socio-economic suburb.
A total of 801 children were in attendance across the observation period. All services offered breakfast to children attending the service. Food was served to children in a family style (i.e. provided multiple options with children allowed to serve themselves) on 49 % (n 24) of days. OSHC staff were observed sitting and eating with the children on 29 % (n 14) of days, verbally promoting healthy eating on 2 % (n 1) and verbally discouraging on 4 % (n 2) of days.
Grains (both wholegrains and refined grains) and dairy products were the most commonly served food groups, being provided on 100 % (n 49) of observation days. Fruit was provided on 22 % (n 11) of days, vegetables on 12 % (n 6) and at least one of these two groups provided on 27 % (n 13). Lean meats and alternatives were provided on 8 % (n 4) of days. Discretionary foods were provided on 96 % (n 47) of days with the most common sub-groups being yeast extract spreads (i.e. Vegemite) (90 % of days), sugary products (i.e. jam and honey) (86 % of days) and discretionary breakfast cereals (14 % of days) (Table 1). On average, 2·4 (±0·7) of the five core food groups (i.e. fruit, vegetables, dairy products, grains, lean meats and alternatives) were offered on each observation day.
All services (n 25) provided their nutrition policies. Eighteen services (72 %) were part of two larger organisations and used the overarching policy of the organisation; therefore, nine unique policies were reviewed. OSHC services with nutrition policies containing specific language on food provision (i.e. measurable) were significantly more likely to offer fruit during breakfast when compared with those services that used non-specific language regarding food provision (i.e. general statements) within their nutrition policies (P= 0·027) (Table 2). OSHC services that reported receiving staff training in healthy eating were observed to provide significantly more vegetables than services that had not received training in healthy eating (P= 0·037) (Table 2). Services located in a high socio-economic suburb provided more refined grain bread (P= 0·032); however, this was not observed for services providing refined grain bread as their only bread option (Tables 2 and 3).

Discussion
This cross-sectional study observed the types of food and beverages provided to children (aged 5–12 years) by twenty-five OSHC services in before school care programmes and how these align with the five food groups of the Australian Dietary Guidelines. We also reported on the food environment of these services and explored how these factors influence the provision of different foods. To our knowledge, this is the first study to assess the food environment in Australian before school care services. Breakfast foods served in before school care were primarily grain, dairy products and discretionary foods, with very few services providing fruit, vegetables or lean meats and alternatives. It should also be acknowledged that this study occurred during the COVID-19 pandemic. While OSHC services were operating normally due to limited state-wide restrictions at the time of data collection, caution around the pandemic may have altered staff behaviours (e.g. staff not sitting and eating with children to maintain social distancing).
A lack of fruit and vegetables was observed within the before school care environment, with fruit offered on only 11 observation days (22 %) and vegetables on 6 d (12 %) and at least one of these groups offered on 13 d (27 %). This is concerning as fruit and vegetables are core foods necessary for children’s healthy growth and development(33). Children consuming breakfast at before school care are therefore missing out on an opportunity to contribute to their recommended servings of vegetables each day, which very few Australian children are currently meeting(4). Fruit and vegetable provision in before school care is less than in Australian after school care, with a recent study observing fruit offered to children on 94 % of observation days and vegetables on 44 %(Reference Crowe, Probst and Norman6). While vegetables are often associated with midday and evening meals(Reference Mcleod, Haycraft and Daley34), fruit is commonly provided during the morning in childcare services(Reference Mireault, Mann and Blotnicky35) and should be encouraged in before school care.
A possible means of increasing fruit provision in before school care could be through service policies. This study found that services with a written nutrition policy containing specific measurable language offered significantly more fruit than services whose policies used non-specific language. This is similar to studies conducted in after school programmes in the USA, with interventions involving nutrition policy development with specific measurable language (alongside other intervention components) increasing the provision of fruit(Reference Mozaffarian, Wiecha and Roth36) and presence of fruit on the menu(Reference Cassady, Vogt and Oto-Kent37). In Australia, regulations require OSHC services to have a nutrition policy(31); however, there is no requirement for these policies to detail the frequency and categories of foods being provided. As a result, more than half of the services in the study (52 %) had a nutrition policy that made general statements around providing nutritious food and following the Australian Dietary Guidelines. Advocating for OSHC regulating bodies to insist on greater detail in nutrition policies, alongside interventions to support services to develop their policies, could lead to the provision of more fruit offered in OSHC settings.
Further to this, vegetable provision in before school care could be promoted through increased opportunities for staff healthy eating training. We found that services that reported receiving annual healthy eating training provided significantly more vegetables than services that received no training. Similarly, a multi-component intervention that included professional development for after school programme staff in the USA demonstrated increased fruit and vegetable provision in services(Reference Beets, Glenn Weaver and Turner-Mcgrievy38). A recent Australian study found that OSHC staff developed increased confidence and capacity around promoting healthy eating from health promotion professional development(Reference Forde, Costello and Devine39). Health promotion practitioners should therefore make evidence-based healthy eating training more accessible to staff working in before school care services.
While this study observed discretionary foods being provided on almost all days, a substantial proportion of these were yeast extracts and sugar products used as spreads on toasted bread. Vegemite, jam and honey were the discretionary spreads most frequently observed, and while they are very high in salt and sugar, they are usually consumed in small amounts. There is, however, the possibility of children overconsuming these spreads, so before school care services should be mindful of monitoring intake if they are being provided. Replacing these spreads with healthier alternatives would be preferable and is the recommended advice for childcare services(40).
Our study observed both wholegrain and refined grain breakfast cereals provided on all observation days. It was encouraging to observe wholegrain cereals being offered every morning, as the consumption of wholegrains has been associated with numerous health benefits such as reducing the risk of diabetes and CVD(Reference Borneo and León41). However, providing these wholegrain cereals alongside refined grain cereals, sometimes high in sugar, could reduce the likelihood of children consuming them. An experiment in a US after school programme found that children more often selected unhealthy foods when given a choice among snack offerings(Reference Beets, Tilley and Kyryliuk42). With discretionary breakfast cereals (> 30 g/100 g total sugar) observed on 14 % of visits, and refined grain breakfast cereals with > 15 g/100 g total sugar observed on 53 % of visits, children could be forgoing the wholegrain benefits for these sugary options. Before school care would benefit from reducing the refined grain breakfast cereal options to increase the likelihood of children selecting and consuming more wholegrains.
Adults encouraging healthy eating both verbally and through role modelling are considered important for positively shaping children’s eating habits(Reference Natale, Messiah and Asfour43). This study observed staff verbally promoting healthy eating on only one observation day and eating with the children on 29 % of observation days. Staff were also observed verbally discouraging healthy eating on two observation days. This finding reveals a need to improve the health-promoting behaviours and knowledge of OSHC staff through methods such as professional development, which has previously led to increased staff promotion of healthy eating in the US after school programmes(Reference Weaver, Beets and Saunders44).
Limitations and strengths
The results of this study should be considered in light of a few limitations. These include: (1) services were located in two local health districts of NSW and may not be representative across NSW or Australia; (2) data collected were on observed food provision so does not reflect actual child consumption; and (3) there is the potential for social desirability bias with service self-reported data. Strengths of this study include: (1) being the first known study to systematically observe food provision and environments in Australian before school care programmes; (2) services were from a diverse geographical and socio-economic area; and (3) food provision was collected observationally rather than with self-report measures.
Conclusion
This study has provided further evidence to the OSHC literature by observing the food environments of Australian before school care, an area with little to no published research. We found that before school care programmes primarily provide grain, dairy products and discretionary foods to children, with very few fruits, vegetables or lean meat and alternatives served for breakfast. Services with a nutrition policy containing specific measurable language on the types and frequency of foods that should be offered were observed to provide more fruit, and services that reported receiving annual healthy eating training provided more vegetables. There were limited OSHC staff observed verbally promoting healthy eating through conversations during breakfast. The findings of this study reveal a need to improve the variety of food groups being offered in before school care through potential strategies such as targeted professional development for OSHC staff and advocating to regulatory bodies for increased specificity requirements in the nutrition policies of service providers.
