Abstract

A pre-school offering a full-day-care service provides for children aged 0–5 years for more than 4 h/d. Researchers have called for studies that will provide an understanding of nutrition and physical activity practices in this setting. Obesity prevention in pre-schools, through the development of healthy associations with food and health-related practices, has been advocated. While guidelines for the promotion of best nutrition and health-related practice in the early years’ setting exist in a number of jurisdictions, associated regulations have been noted to be poor, with the environment of the child-care facility mainly evaluated for safety. Much cross-sectional research outlines poor nutrition and physical activity practice in this setting. However, there are few published environmental and policy-level interventions targeting the child-care provider with, to our knowledge, no evidence of such interventions in Ireland. The aim of the present paper is to review international guidelines and recommendations relating to health promotion best practice in the pre-school setting: service and resource provision; food service and food availability; and the role and involvement of parents in pre-schools. Intervention programmes and assessment tools available to measure such practice are outlined; and insight is provided into an intervention scheme, formulated from available best practice, that was introduced into the Irish full-day-care pre-school setting.

The funding of early education should be prioritised over other public investments due to its diverse and sustained benefits on children's academic and developmental capabilities( Reference Belfield 1 ). The education of children, in full day care, in the development of healthy eating patterns, is becoming predominantly that of the child-care provider, ‘providers’ being defined as ‘all early learning and care professionals’ that are involved with the care of children( Reference Lanigan 2 ).

With many parents now relying on child-care workers to share in their role of guardian to their child's nutrient intake( 3 ), the child-care setting has the potential to be a successful vehicle for health promotion( Reference Gupta, Shuman and Taveras 4 ) and obesity prevention( Reference Story, Kaphingst and French 5 , Reference Kaphingst and Story 6 ). While the quality of early care for children has been noted for some time to impact on cognitive and school achievement from pre-school age to adolescence( Reference Vandell, Belsky and Burchinal 7 ), public health concern has recently been expressed regarding the nutritional quality and amount of food served in the pre-school setting( Reference Briley and McAllaster 8 ).

Young children have micronutrient requirements that are, relative to their energy needs, greater than those of adults; therefore, it is necessary that the nutrient density of their diet is high( Reference Dwyer, Butte and Deming 9 ). Indeed, Doyle et al. ( Reference Doyle, Harmon and Heckman 10 ) recommended that intervening between zero and 3 years of age has the potential to alter children's development patterns thus protecting them against risk factors in their environment and Koletzko et al. ( Reference Koletzko, Brands and Demmelmair 11 ) noted that a difference in nutrition provision at important points in early life, both in utero and after birth, can programme a person's development, metabolism and health. Young children of pre-school age need a physical and social environment that will support not only their physical requirements but also their emotional, intellectual and motor skill development( Reference Dwyer, Garrow and James 12 ). Food-related experiences in the first 2 years of life have been shown to influence dietary variety in school-aged children( Reference Skinner, Carruth and Bounds 13 ). Healthy nutrition( Reference Singer, Moore and Garrahie 14 , Reference teVelde, Twisk and Brug 15 ) and physical activity habits( Reference Telama 16 ) developed in childhood have been found to track into adolescence and beyond, while evidence also exists that exposure to poor practices may lead to unhealthy habits that persist into adulthood( Reference Batsell, Brown and Ansfield 17 ).

With many people worldwide now accessing out of home child-care, and large numbers of children spending numerous hours per week in non-parental care, researchers have called for studies that explore the current nutrition and physical activity practices in child-care settings( Reference Larson, Ward and Benjamin Neelon 18 ). With this in mind, the need to ensure best practice in pre-school nutrition and physical activity is paramount. Although the American Dietetic Association notes that child-care regulations reflect a minimum standard and that actual practice should greatly exceed them( 19 ), it would appear that in many countries poor nutrition and physical practice have been documented; in the UK( Reference Moore, Nelson and Marshall 20 , Reference Parker, Lloyd-Williams and Weston 21 ), the USA( Reference Ball, Benjamin and Dunne 22 Reference Sisson, Campbell and May 25 ), Australia( Reference Zask, Adams and Brooks 26 ), Holland( Reference Gubbels, Kremers and Stafleu 27 ) and Ireland( Reference Jennings, McEvoy and Corish 28 , Reference Johnston Molloy, Corish and Kearney 29 ).

Kaphingst & Story( Reference Kaphingst and Story 6 ), however, have noted that although much research has been undertaken with regard to policy and nutrition and physical activity advocacy in the school setting, the child-care setting has, in contrast, been largely overlooked. Flynn et al.( Reference Flynn, McNeill and Maloff 30 ), in reviewing best practice in reducing obesity and related chronic disease in children and young people, noted that there are a few interventions in the pre-school setting and recommended that funding should be directed to develop prevention programmes in this setting. In fact, this dearth of research interest is evident in the literature with, to date, little published intervention research from Europe, the UK and Ireland. The vast majority of child-care and health-related practice research in pre-schools emanates from the USA( Reference Erinosho, Dixon and Young 24 , Reference Benjamin, Ammerman and Sommers 31 , Reference Ball, Benjamin and Ward 32 ), with a small number of similar studies coming from Australia( Reference Honisett, Woolcock and Porter 33 Reference Pollard, Lewis and Miller 35 ). It is only in the very recent past that any cross-sectional research publications have emerged regarding practice in the UK( Reference Parker, Lloyd-Williams and Weston 21 , Reference Lloyd-Williams, Bristow and Capewell 36 ) and Europe( Reference Gubbels, Kremers and Stafleu 27 ), with to our knowledge no evidence of intervention research in this area to date. Indeed, while many studies rely on reported practice( Reference Lloyd-Williams, Bristow and Capewell 36 ) few are based on researcher observation of practice in the child-care setting, which is considered the ‘gold standard’( Reference Gittelsohn, Shankar and Pokhrel 37 ).

At present, in Ireland, child-care regulations( 38 ) govern the provision of out-of-family care in Ireland and inspections of child-care premises are made on a regular basis; in order to assess the health, safety and welfare, and promote the development of children attending pre-school services; however, little else is known about the nutrition and health-related practices in these settings and little data are available on the actual food served to pre-school children with previously published studies obtaining data on the food provided indirectly from the child-care providers( Reference Jennings, McEvoy and Corish 28 ). While ‘Food & Nutrition Guidelines for pre-schools’( 39 ) are available they are not mandatory, which would suggest that methods to encourage the provision of nutritious food in this setting must be pursued. The present paper will review the international guidelines and recommendations pertaining to health promotion best practice in the pre-school setting; outline the intervention programmes and assessment tools available to measure such practice; and provide insight into an intervention scheme, formulated from available best practice, that was introduced into the Irish pre-school setting.

Definition of pre-school child-care

The definition of a ‘full-day-care pre-school service’ differs depending on the country in which it is offered; in the UK( 40 ) it is defined as ‘day care for children under eight for a continuous period of 4 h or more in any day’, while in Ireland it is stated to be ‘a pre-school service offering a structured day-care service for pre-school children for more than 5 h/d; and which may include a sessional pre-school service for pre-school children not attending the full day-care service ( 38 ). In the USA it is reported that the average time spent by 4½-year-old children in non-maternal care was 27 h/week( 41 ). In Ireland, the average 3-year-old was found to spend 23 h/week( 42 ) and the average 9-month-old 29 h/week, in non-parental care( 43 ). As a child who attends pre-school on a full-time basis could potentially spend 10 h every day, 5 d/week and 48 weeks of the year in care, responsibility has to be placed on child-care facilities to provide sufficient nutrition and a conducive environment to encourage healthy food habit formation( Reference Bristow, Capewell and Abba 44 ).

Guidelines for best nutrition and health-related practice in the child-care setting

Comprehensive best health-related practice guidelines for the child-care setting have been available in the USA for many years( 45 ), with benchmarks specifically for nutrition in the child-care setting published by the American Dietetic Association( 3 , 19 ) and physical activity guidelines for the age group also developed by the National Association for Sport and Physical Education( 46 ). However, it is only recently that a set of guidelines were published for the UK( 47 ) following a review of the need for such guidance in the setting( Reference Sharp, Mucavele and Nelson 48 ) and the development of guidelines in Northern Ireland( 49 ), Scotland( 50 ) and Wales( 51 ). The guidelines developed for Ireland, however, were published in 2004( 39 ) and have not been updated since this time.

While guidelines are available in a number of jurisdictions regarding the promotion of best nutrition and health practice for the early-years setting( 39 , 45 , 47 , 49 52 ), it is of concern that regulations for the pre-school setting, where they exist, are set to ensure minimum standards only. Advocates for quality in the pre-school setting have expressed anxiety that there is a danger that some will view these minimum standard regulations as equivalent to quality and aim to provide minimum standard service only for children in their care( Reference Horgan 53 ). Added to this, is the disquiet stemming from recent reviews of child-care regulations in the USA where many States do not in fact have strong regulations governing healthy eating and physical activity in these settings( Reference Kaphingst and Story 6 , Reference Benjamin, Taveras and Cradock 54 , Reference Benjamin, Copeland and Cradock 55 ). It would appear that regulations concentrate instead on safety in the child-care facility( 38 , Reference Ammerman, Ward and Benjamin 56 ), with less focus being placed on nutrition and the food-service environment. This finding is somewhat surprising when one considers that the nutrition environment plays a critical role in the food habit development of the pre-school-age child( Reference Briley and McAllaster 8 ), and because a large number of mothers now work, child-care, regardless of the setting, should be of high quality to maximise possible developmental outcomes during the early years( Reference Rosenthal, Crowley and Curry 57 ).

The main factors reported to affect nutrition and health-related practice in the child-care setting are: existence of policy on nutrition education, nutrition service and nutrition resources; nutrition curriculum, food availability; physical activity as part of the curriculum; knowledge, attitude and practices of staff; and the role and involvement of parents regarding nutrition issues( Reference Montague 58 ).

International best practice: evidence for practice change

Service and resources

Policy

Development of policy allows consistent health promotion messages to be generated( 47 ) and to be effective it should be developed by everyone in the pre-school community through a process of consultation and review( 52 , 59 ). The policy should be given to all parents and staff, and it should also be posted in a visible location( 39 , 47 ). A written policy may play a role in chronic disease prevention by facilitating the implementation of healthy nutrition and physical activity practices and habits for children in the child-care setting( Reference Story, Kaphingst and Robinson-O'Brien 60 ). Policies tend to take many different formats such as parent handbooks, staff handbooks, parent notices, and other documents( Reference Falbe, Kenney and Henderson 61 ), and there would appear to be a link between child-care practices and the presence of health policies, with written policies encouraging healthy behaviour linked with modelling of healthy staff behaviour( Reference Erinosho, Hales and McWilliams 62 ) and increased healthy food consumption( Reference Vereecken, Huybrechts and Maes 63 ). Little appears to be known about the prevalence of health and wellness policies in child-care services; however, studies undertaken would suggest that policy development in child-care facilities appears to be limited in the USA( Reference Falbe, Kenney and Henderson 61 ), UK( Reference Parker, Lloyd-Williams and Weston 21 , Reference Lloyd-Williams, Bristow and Capewell 36 ) and in Ireland( Reference Jennings, McEvoy and Corish 28 ).

Staff training

Although it is acknowledged that competent and well-trained workers are key to the early education environment, it would appear that policy makers and the public are often aghast at the poor levels of education and remuneration amongst this workforce; a wide discrepancy being apparent between the importance attributed to the role of early educators and the remuneration and respect afforded to this group( Reference Early and Winton 64 ). Training for the child-care setting can range from post-secondary school to degree level qualifications( Reference Mahoney and Hayes 65 ).

To offer a high quality service pre-schools must: hire properly trained staff; ensure optimum group numbers and staff to child ratios; adhere to an educational and developmentally appropriate curriculum; and provide a safe and healthy environment for the children in their care, however, these basic requirements are expensive and in most cases require additional funding and resources( Reference Eichman 66 ). Clark et al. ( Reference Clark, Anderson and Adams 67 ) determined that providers need more than training on best practice, particularly relating to infant feeding; they also need information on how and why they should comply with standards, and while enforcement may be one way to encourage child-care providers to follow child-care regulations, relative infrequency of site visits may prevent this from being the most effective method to improve feeding practices in child-care centres; instead it has been suggested that provision of training and professional development opportunities or compensation (suggestions for which were not outlined by the authors) may be better strategies to encourage best practice( Reference Benjamin, Taveras and Cradock 54 ).

If child-care centres are to engage in obesity prevention, then feeding practices that promote healthy weight should be stressed to staff( Reference Sigman-Grant, Christiansen and Fernandez 68 ); in comparing the practices of providers who had received nutrition-related training, to those who had not, those with training were significantly more likely to engage in supportive feeding practices; however, the source of the information and the person who provided the information were found to be more important to those being trained that the frequency of training provision. Information provided by educators qualified to teach nutrition, and who were perceived to be a credible information source, was more likely to result in positive change in practice, whereas training provided by personnel in health departments who did not have relevant nutrition credentials, or experience, was negatively related to practice change. The authors speculated that this may be because health departments traditionally have a remit for environmental safety and may, in fact, prohibit positive child-feeding practices such as self-service or child food-preparation involvement.

Health promotion and education

Nutrition education is a key constituent of lifelong healthy eating and should start from the early stages of life( Reference Pérez-Rodrigo and Aranceta 69 ). Dwyer( Reference Dwyer, Garrow and James 12 ) recommended that pre-schools should include nutrition education to expose children to new eating experiences in a supervised and safe way and Lanigan( Reference Lanigan 70 ) advised that care-givers play an important role in shaping childhood nutrition and activity practice through direct modelling and instruction. Learning about food and physical activity should be integrated into the curriculum of the pre-school and should be included in everyday activities( 47 , 71 ). A comfortable and supportive dining room should be provided( Reference Gable and Lutz 72 ) and food should never be used as a reward or punishment( 45 ). While food is often part of celebration, guidelines recommend that because there may be so many events and celebrations in large child-care settings other ways of marking occasions should be used i.e. party games or face painting rather than the more traditional sweets, crisps and fizzy drinks( 39 , 49 ). Indeed in Norwegian child-care the aim of a celebration is to make the child the focus of the day and activities centre on wearing a special hat or raising a flag( 73 ).

Child-feeding utensils

There are a number of different recommendations regarding the provision of age-appropriate eating and drinking utensils and other dining equipment, with the standards in the USA( 45 ) being extremely comprehensive in outlining best practice in this area: food should be served to young children from dishes and not directly from factory containers, the correct height and sitting position for children at the table, the type and size of eating utensils to be provided, and the need for plate provision at all mealtimes for all age groups( 45 ). Guidance in Ireland does not include such specifics; however, it does include information on the importance of cup introduction to children( 39 , 74 76 ).

Physical activity and outdoor time

There is a relative lack of physical activity research in the pre-school age group, but it is thought that many activities in which pre-schoolers engage are relatively sedentary in nature( Reference Hodges, Smith and Tidwell 77 ). Paediatricians and other health-care professionals have a role in highlighting to parents and care-givers the importance of nurturing these skills through unstructured and structured play( Reference Riethmuller, Jones and Okely 78 ). In 2002, the National Association for Sport and Physical Education( 46 ) developed the first set of guidelines for physical activity in pre-school-aged children. However, no specific recommendations for the child-care setting existed until a set of guidelines specifically for this setting was developed in the USA as part of the Nutrition and Physical Activity Self-Assessment for Child Care (NAPSACC) project( Reference McWilliams, Ball and Benjamin 79 ). These guidelines were collated from a number of different organisations, the exception being when no recommendations were available; a best practice guideline was developed through research evidence and expert opinion. In Ireland, the National Association for Sport and Physical Education guidelines have been adopted for use in the child-care setting( 80 ). It has been reported that the pre-school attended, its quality level and the presence of policy are all determinants of physical activity( Reference Pate, Pfeiffer and Trost 81 Reference Cardon, Labarque and Smits 84 ).

Outdoor time has been significantly correlated with physical activity in pre-school children( Reference Burdette, Whitaker and Daniels 85 ) with time spent in the outdoors being one of the most consistent predictors of physical activity levels among this group( Reference Sallis, Prochaska and Taylor 86 ). It is recommended in many countries that children in child-care should be facilitated to spend time outdoors at least once every day and preferably more often that this( 19 , 49 ). However, it would appear that outdoor time provision varies( Reference Tandon, Garrison and Christakis 87 ) with inadequate clothing, injury concerns; financial worries and a focus on prioritising academic learning being the largest barriers to physical activity and outdoor time in the pre-school setting. The development of a good rapport with parents regarding the importance of outdoor play is essential to encourage parents to provide appropriate outdoor clothing( Reference Copeland, Sherman and Kendeigh 88 , Reference Copeland, Sherman and Kendeigh 89 ).

Food service and availability

Altering the type of foods available to children in schools has the potential to greatly affect their dietary intake and risk of childhood obesity( Reference Fox 90 ). Relatively little data are available on food service in the pre-school setting. A number of studies have questioned providers about the food they provide to children, while some studies have directly observed food served or eaten by pre-school children. Guidelines in the USA recommend that food should be offered to children every 2–3 h( Reference Benjamin 91 ), while in the UK and Ireland guidelines recommend that children may need to be offered three meals and two to three snacks in a day depending on the length of time they spend in care( 39 , 47 ). Worryingly however a number of studies in the USA have explored the food and beverages served to children in the child-care setting and demonstrated inadequate pre-school provider( Reference Ball, Benjamin and Dunne 22 , Reference Erinosho, Dixon and Young 24 , Reference Padget and Briley 92 ) and parent( Reference Sweitzer, Briley and Robert-Gray 93 ) food and fluid provision while a study in Ireland detailed that thirteen of fifty-four Irish full-day-care pre-school managers reported failure to provide at least two meals and two snacks for children aged 1–5 years( Reference Jennings, McEvoy and Corish 28 ).

The UK School Food Trust( 47 ) recommends that children should be encouraged to serve themselves water throughout the pre-school day, while the guidelines for child-care settings produced by the Government of Nova Scotia( 94 ) outline that dehydration, even in its mildest form, can negatively affect brain function, energy levels and alertness in children. It would appear however that self-service of fluids is not widely available( Reference Erinosho, Dixon and Young 24 ). Milk and water are the best drinks for pre-school children( 39 , 75 ). Squash, cordial, fizzy or carbonated drinks are not recommended as daily drinks due to their high acid content that may increase risk of tooth decay( 75 ). Unsweetened fruit juice should only be provided once in the day and should be diluted well with water( 39 , 75 ); sweetened juices are not recommended( 75 ) and consumption of beverages containing artificial sweeteners is not recommended for children under the age of 5 years( 39 , 75 , 94 ) as they have poor nutritional value and tend to displace milk, which is a nutrient-rich food ( 94 ). However, despite these guidelines a wide variation in drink provision in this setting has been reported( Reference Jennings, McEvoy and Corish 28 , Reference Tandon, Garrison and Christakis 87 , Reference Wilson 95 ).

‘Family style food service’

The promotion of the ‘family meal’ has been advocated as a potential public health tool to improve dietary quality and educational and social outcomes and reduce overweight( Reference Cason 96 ). Education about ‘family style food service’ and how children's feeding issues impact on their eating behaviour is described as necessary( Reference Lohse, Rifkin and Arnold 97 ). ‘Family style food service’ is defined as facilitation of meals where child-sized tables are set with appropriate plates and utensils and food is passed between children and adults; children are encouraged to serve on to their own plates and pour their own drinks from small jugs, with the four main components being: table setting, food preparation, self-service and clean-up. The process provides many advantages for a child's development by promoting motor skills, language, self-esteem, social skills, table manners and independence and may help with fussy eating, encouraging a picky eater to try and accept foods that it sees its peers serving and eating( 98 ). The development of a positive meal-time experience for children is an important part of healthy food habit formation, and the care-giver should be a role model who sits at the table and eats with the children( 3 , 45 ). Setting simple rules for children at the table is necessary and important( 3 , Reference Benjamin 91 ) with social interaction and conversation, especially conversation regarding nutrition and food, enhancing the meal-time experience and helping children to accept food and develop appropriate eating behaviours( Reference Hendy and Raudenbush 99 ).

Guidelines exist in the USA and UK for child:adults ratios, and for their expected interaction, at mealtimes( 45 , 47 ). Despite these recommendations, studies found that pre-school staff do not always sit with children and a few eat with children( Reference Sigman-Grant, Christiansen and Branen 23 , Reference Addessi, Galloway and Visalberghi 100 Reference Hendy 103 ) and although the reported levels of ‘family style food service’, sitting and eating with children were high( Reference Sigman-Grant, Christiansen and Branen 23 , Reference Jennings, McEvoy and Corish 28 ), poor practice was noted through direct observation techniques( Reference Nahikian-Nelms 102 ).

In the USA, care-givers are recommended to encourage young children to hold cups, and to use spoons and their fingers( 45 ), whereas Benjamin( Reference Benjamin 91 ) recommends allowing young children to make a mess when they are eating as they need to explore food. Self-feeding delineates the roles and responsibilities of adults and children in the feeding relationship, with the adult being responsible for provision of adequate nutritious food and the child being then responsible for deciding how much to actually eat( Reference Benjamin 91 , 94 , Reference Satter 104 ). A large-scale study of meal-time practices in pre-schools across four States in the USA determined that only 38 % reported allowing pre-school children to serve themselves( Reference Sigman-Grant, Christiansen and Branen 23 ); however, studies have demonstrated that allowing children to serve themselves facilitates self-regulation( Reference Mrdjenovic and Levitsky 105 Reference Orlet Fisher, Rolls and Birch 107 ). Poor self-regulation and inability to delay gratification have been linked with weight gain( Reference Francis and Susman 108 Reference Tsukayama, Toomey and Faith 110 ).

Role and involvement of parents

Child-care providers should inform parents regularly about children's food learning activities and offer nutrition education programmes to parents at least twice yearly( Reference Benjamin 91 ). While the importance of engaging parents in their child's development is undisputed, the role of the child-care centre in prompting this interaction is somewhat more tenuous, with issues apparent that may impact on the child-care establishment's ability to promote parents to undertake best practice behaviours with their children. A poor partnership between child-care providers and parents has been shown to exist; child-care workers reporting that they rarely involved parents in menu planning or dietary discussions, a few wishing to negotiate food provision with parents and the majority reporting that meal-time struggles with children were due to different foods they got from parents while at home( Reference Moore, Nelson and Marshall 20 ). Interestingly while parents have reported satisfaction with the quality of pre-schools that their children attend it would appear they may be unaware of the food provided to their children or they may not wish to admit that quality may be poor while they are exposing their children to such provision. Particularly, when there may be a limited choice parents do not wish to speak disparagingly of their child-care centre( Reference Benjamin, Haines and Ball 111 ). While parents play a valuable role and have a powerful influence on their children's eating habits by serving as a model in choosing foods, determining food availability, planning meals and in the socialisation involved in eating( 3 ), and it is recommended that parents are involved in all areas of their child's child-care programme, including the planning of their meals, evidence would suggest that this is not happening( Reference Padget and Briley 92 ).

Programmes, interventions and evaluation tools

Lanigan et al.( Reference Lanigan, Barber and Singhal 112 ) note that there are a few nutrition interventions in the pre-school setting and recommended that funding should be directed to develop such programmes, while Ward et al. ( Reference Ward, Hales and Haverly 113 ) suggest that because the pre-school environment has the capability to have a positive effect on many children's health it is a ‘unique and important setting for interventions to prevent childhood overweight’. Health professionals have been encouraged to work with parents, guardians and child-care workers to both prevent and treat obesity in young children( 19 ). Summerbell( Reference Summerbell 114 ), however, expressed the need for caution when perusing intervention studies noting that one programme will not meet all needs and that methods that work with older children and adults may not, in fact, work with younger children.

To be effective it has been recommended that theory-based education programmes are not sufficient; instead practical measures need to be included, for example healthy heart behaviour promotion programmes need to teach pre-school children how to take care of themselves by helping them to: learn how to keep themselves healthy (good knowledge), believe that healthy living is really important to them (good attitude); be able to practice good behaviour, not just talk about it (good actions and behaviour)( Reference Hayman, Williams and Daniels 115 ).

Curriculum and education-based programmes

ToyBox is a European Union funded study that aims to develop and test an innovative evidence-based obesity prevention programme for children aged 4–6 years, based in kindergarten, but with family involvement( 116 ); this programme is currently being undertaken by a multidisciplinary team of researchers from ten European countries and is ongoing.

A number of initiatives that include intervention and control arms, in various countries, have demonstrated positive effects on children within the pre-school setting. In the USA, the Color me Healthy programme, involved the measurement of 263 pre-school children's fruit and vegetable intake 1 week before the introduction of an interactive nutrition and physical activity curriculum programme, and again at 1 week and 3-month intervals post-intervention. Fruit and vegetables were weighed before, and immediately after, children's food snack time. It was demonstrated that those children who received the Color me Healthy programme curriculum, significantly increased their fruit (20·8 %) and vegetable snack consumption (33·1 %) from baseline to a 3-month follow-up assessment, compared to those children who did not( Reference Witt and Dunn 117 ).

A clustered, randomised, controlled trial of migrant children from forty public pre-schools in Switzerland, which implemented a lifestyle intervention demonstrated, through direct measurement, increased aerobic fitness and motor agility and improved body fat and waist circumference in children in the intervention compared to the control group. However, no effect on measured physical activity or on BMI was noted( Reference Puder, Marques-Vidal and Schindler 118 ).

The Munch and Move programme was initiated in Australia to support child-care professionals to promote healthy eating and physical activity. An evaluation of intervention (n 15) and control (n 14) pre-school services assessed lunchbox contents, fundamental movement skills, policies and practices and staff knowledge, attitudes and confidence regarding healthy eating, physical activity and use of screen time. A significant improvement was directly observed in fundamental movement skills in children in the intervention arm of the study and the number of movement skill sessions occurred significantly more often than in the control group after the intervention. A lunchbox audit also demonstrated significant reduction in sweetened beverages in the intervention group. No significant difference was noted in the other areas studied with the authors hypothesising this may have been due to the short implementation time (5 months) or the deliberately low intensity programme content( Reference Hardy, King and Kelly 119 ). In a separate Australian intervention, The Tooty Fruity Vegie project, researchers worked with eighteen pre-schools catering for children aged 3–6 years. The study was a clustered, randomised, controlled intervention that aimed to decrease overweight and obesity prevalence and included both nutrition and physical activity strategies. The follow-up time was greater in this study than the ‘Munch and Move’ intervention; 10 months. At follow-up, fundamental movement skills, lunchbox audit and anthropometric measurements of children were undertaken; in addition, parents were surveyed on their children's dietary intake and physical activity behaviours. Children in intervention pre-schools significantly improved their movement skills, ate more fruit and vegetables and were less likely to have unhealthy food in their lunchboxes. They also displayed significant and welcome changes in waist circumference and BMI Z scores when compared with the control group( Reference Zask, Adams and Brooks 26 , Reference Adams, Zask and Dietrich 120 ).

The ‘Early Years Health Promotion Project’ was set up in North West Ireland to support child-care services to develop and implement healthy nutrition and physical activity policies, to implement programmes of physical activity and quality outdoor play and to promote the benefits of nutrition, physical activity, oral health and sun safety to parents, children and child-care workers( 121 ). Upon evaluation, the project authors reported a high incidence of healthy eating, physical activity and outdoor play policies and a significant attitudinal change to health promotion activities amongst parents, child-care services management and staff, and children. Results, however, were based on manager (n 31) feedback through quantitative and qualitative questionnaire administration, rather than observed practice and a control group was not available for comparison.

Development of tools to assess and promote best practice in early child-care

There is a need to develop high quality measurements for food and physical activity environments to enable an understanding of their influence on diet and activity behaviour; measurement of such environments is, however, relatively recent with both self-reported and observer-based methodologies being developed in a number of disciplines such as nutrition, psychology, geography and public health( Reference McKinnon, Reedy and Handy 122 ). Child-care settings have unique physical and social aspects that are not measured adequately by tools designed for the assessment of the school, home or built environment( Reference Bower, Hales and Tate 83 ).

Pre-school award schemes

The ‘health promoting schools’ approach’ entrenches healthy eating and physical activity into the school's policies, physical environment, curriculum and community; healthy award schemes have emerged and supply a structured framework, health-related targets and external support for schools. While these concepts have been mostly targeted to the school environment, they may also be appropriate for the early child-care and education setting( Reference Honisett, Woolcock and Porter 33 ).

In Australia the Kids – go for your life programme employs an award system to encourage schools and early childhood settings to support healthy eating and physical activity using the health promoting schools’ approach( Reference Honisett, Woolcock and Porter 33 ). The development of the programme award scheme involved a number of phases: identification of the most appropriate design for such an award programme; determination of the most appropriate components of such a scheme; and the testing of the award programme scheme in the field. A limitation of this award scheme was that it was based on self-assessment; the child-care settings, in particular, scored their practice very well against the award criteria, perhaps overestimating the health practice status of their services.

The Start Right-Eat Right Award Scheme was implemented in Western Australia and is based on using an incentive to motivate improvement in food service in the child-care setting( Reference Pollard, Lewis and Miller 35 ). The development of the scheme involved four stages: needs assessment; piloting of award and development of resources; implementation of award, including training of staff, menu assessment and dietitian visit; and maintenance of award scheme, with centres receiving the award for one year; renewal follows a further application, with resubmission of menus and an award checklist, and possible random site visit to confirm award criteria are being met. A telephone evaluation of the scheme determined that those centres engaged in the incentive scheme were more likely to follow national guidelines. The promotion of practices that were conducive to appetite self-regulation, and the provision of healthy celebration foods were reported more often, when compared to centres not engaged with the intervention( Reference Golley, Bell and Matwiejczyk 34 ).

Assessment tools used in the child-care setting

Self-assessment tools

There would appear to be a number of curriculum and education-based interventions and programmes targeting the child-care centre; however, until the development of the NAPSACC intervention in the USA, it seemed that there were no published studies of intervention studies focused on the environment and policy and that targeted pre-school providers( Reference Ammerman, Ward and Benjamin 56 ). The authors recommended that improvements to play space, equipment, foods served, staff role modelling and health-related policies would in turn lead to sustainable improvements in nutrition and physical activity. The NAPSACC is a self-assessment, environmental intervention for the child-care sector; its aim is to improve the diet, physical activity, social and physical environment to support healthy weight amongst children, boost the marketability of the centres and provide staff with continuing education regarding nutrition and physical activity( Reference Ammerman, Ward and Benjamin 56 , Reference Benjamin, Neelon and Ball 123 , Reference Trost, Messner and Fitzgerald 124 ). The authors note that validity testing sores on the self-assessment tool were higher than those on a simultaneously tested observation tool, but that this was expected as ‘self-report may be associated with social desirability. Child-care directors may wish to describe their center in the best possible light’; concluding that the self-assessment tool was developed to ‘spark interest’ among child-care workers and a more objective measure such as the Environment and Policy Assessment and Observation tool may be warranted to capture accurately child-care policies and practices( Reference Benjamin, Neelon and Ball 123 ).

A study group in Connecticut, USA( Reference Henderson, Grode and Middleton 125 ), developed and validated a self-administered survey to assess the nutrition and physical activity environment of child-care centres. The survey is completed by child-care directors and validation included in-person interviews with directors and 3–4 h observation of the environment. Criterion agreement was highest for policy determination and lowest for physical activity and determination of the barriers to health promotion in this setting. Food score assessment agreement was moderate.

Observation-based tools

The Environment and Policy Assessment and Observation instrument is a tool developed to assess child-care centres’ nutrition and physical activity environments, policies and practices. It is administered by trained observers using direct observation and document review. It was developed to evaluate the NAPSACC intervention( Reference Ward, Hales and Haverly 113 ) and followed on from a study by Ball et al. ( Reference Ball, Benjamin and Ward 32 ) in which the development of an observation-based tool for use in the determination of the amount and type of food served and eaten by children in the child-care setting was established. Use of the environment and policy assessment and observation instrument to determine intervention effect of the NAPSACC intervention determined no significant difference between control and intervention pre-schools in nutrition or physical activity environment measurements( Reference Ward, Benjamin and Ammerman 126 ). The authors note that the reason for this is unclear and suggest a number of possible causes. The intervention was low cost, was introduced through the public health system and requested services to choose small areas of the environment to change, rather than requiring them to alter the whole environment. The use of self-assessment in the NAPSACC programme may also have affected the results achieved. As the Environment and Policy Assessment and Observation instrument was the first tool developed to specifically measure the nutrition and physical activity environments of pre-school settings, it was hypothesised that insignificant results may have been due to the tool itself and the authors suggested the need for further study in this regard.

Alkon et al. ( Reference Alkon, To and Wolff 127 ) describe their development of a health and safety checklist for use in the early years’ setting: the California Childcare Health Programme Health and Safety Checklist. The checklist was developed by undertaking a literature review, identifying best practice or the gold standard of practice, consulting an advisory group and revising the checklist; and piloting the checklist. The checklist consisted of a number of criteria grouped into subscales and each criterion was rated on a three point scale of ‘meeting, partially meeting or not meeting’ national standards. Face, content and construct validity and reliability were also established for the tool.

The Encouraging Healthy Activity and Eating in Childcare Environments pilot project was carried out with seventy-two child-care providers from forty-five child-care settings in the USA. Child-care practices were measured using an observation tool the Protocol for Mapping Policies and Practices; focus was on three areas: feeding practices; nutrition education and family communication. Providers were questioned regarding their knowledge and beliefs about their role in supporting healthy eating. Observation data and provider survey data were collected at baseline and 1 year post-intervention. The intervention consisted of a 3-h training session with providers. Results demonstrated that a reduction in reported misconceptions was significantly associated with improved feeding practices, and that changes in reported efficacy and feeding knowledge had a significant role to play in changes observed in nutrition education and family communication( Reference Lanigan 2 ).

Schwartz et al. ( Reference Schwartz, Lund and Grow 128 ) developed an instrument to measure school wellness policies from kindergarten to grade twelve. The aim was to: develop a coding system for schools wellness policies to assess them for strength and comprehensiveness; and to score each policy to enable policies to then be compared. The tool consists of ninety-six items and evaluates seven goal areas including: nutrition education; USA standards for nutrition programmes and school meals; nutrition standards for all other available foods and beverages; physical education; physical activity; communication and promotion of nutrition and health; evaluation of health-related activities. While the tool was described as a reliable and valid measure of school wellness policy quality, a limitation of the study was the impossibility of determining whether policy score assigned by the tool would predict the school environment or the student behaviours. Another tool, The Wellness Child Care Assessment Tool, is a sixty-five-item measure of five areas of pre-school practice: nutrition education; food and beverage nutrition standards; healthy eating promotion; physical activity; communication and evaluation strategy( Reference Falbe, Kenney and Henderson 61 ). One of the limitations of this tool was its inability to predict whether the scores attained predict the quality of the nutrition and physical activity environment and practice.

Environmental and policy-led interventions in Ireland

The placement of children in care outside the home has increased rapidly in Ireland in recent years. Between 2002 and 2007, an increase of 42–48 % was reported in the number of households using out-of home care( 129 ) with the most common types of non-parental care reported to be: an unpaid relative; a childminder/au pair or nanny, or a crèche, Montessori, playgroup or after-school facility. The use of a crèche/Montessori or play group for pre-school children increased from 14 % of households in 2002 to 24 % of households in 2007( 129 ). The more recent Growing Up in Ireland study reported that 38 % of Irish 9-month-old children participate in non-parental child-care for more than 8 h/d, with 11 % attending crèches or pre-school centres( 43 ) and by the age of 3 years, 50 % of children attend out-of-home child-care( 42 ). National policy encourages more women to enter the workforce thus increasing the need for non-parent care in the community. In the latter part of the decade 2000–2009, just over 68% (60·8 %) of women were in the workforce in Ireland( 130 ), with rates of part-time work for women rising from 21 % of those employed in 1993, to 31 % in 2003 and 32 % in 2007( Reference Russell and McGinnity 131 ). Interestingly, the working arrangements of parents impacts on the use of child-care in Ireland with 68 % of pre-school aged children who lived with both their parents using child-care when both parents were working; 59 % using it when the mother worked part-time and the father worked full-time and 29 % using it when the father did not work and the mother worked full-time( 129 ). With the increase in demand for child-care places, successive governments have directed funding to the creation of child-care places in the community (not for profit) and private (for profit) sectors; the National Child-care Strategy 2006–2010( 132 ) aimed to develop the child-care infrastructure in Ireland; with a budget of €575 million, an increase of 50 000 child-care places was estimated.

In Ireland, little data are available on the actual food served to pre-school children with previously published studies obtaining data on the food provided indirectly from the child-care providers( Reference Jennings, McEvoy and Corish 28 ). The Healthy Incentive for Pre-schools project is an ongoing project in the midlands of Ireland. It was developed as an incentivised intervention to promote healthy nutrition and health-related practices in the pre-school setting, through the use of a specifically developed and validated nutrition and health-related evaluation tool (the Pre-school Health Promotion Activity Scored Evaluation Form) and accompanying educational resource (the Pre-schools Nutrition and Health Education Resource).

Forty-two pre-schools in the midlands of Ireland completed the Healthy Incentive for Pre-schools project. The study cosists of three phases: pre-intervention data collection; intervention administration that involved randomly dividing pre-schools into two training groups: a ‘manager trained’ group, in which only the manager received training and a ‘manager and staff trained’ group, in which a staff training session was provided in addition to the manager training; and collection of post-intervention data. Data were collected by direct observation of health promotion practice by a Research Dietitian spending one full day in each pre-school both pre- and post-interventions.

Pre-intervention, poor food and fluid provision and inadequate and inappropriate food service, physical activity and outdoor time were observed. Data collected using the Pre-school Health Promotion Activity Scored Evaluation Form demonstrated a significant improvement in practice across the two time-points in both training groups. No significant difference was detected between the training groups’ health promotion activities post-intervention with no significant benefit of additional staff training. The ability of pre-schools to self-assess their own practice using the form was measured and it was determined that subjective (pre-school provider self-assessment) resulted in significantly higher scoring than using an objective (Research Dietitian)-based approach. These findings suggest the need to investigate pre-school health promotion practices in other regions in Ireland with the view to improving such practice if required.

Conclusions

With the high usage of non-parental child-care in Ireland( 133 ) and the growing incidence of childhood obesity( 134 ), there is a need for a co-ordinated approach to ensure that the quality of child-care provided is based on best practice and not minimum standards. The provision of funding to pre-schools should be linked with quality, with financial support only provided in tandem with a scheme that promotes best practice and which incorporates a monitoring system that is based on direct observation.
