ABSTRACT
Background: Breakfast is often described as the most important meal of the day. The regularity of wholesome, daily meal patterns comprised of healthy foods is important for the physical and mental development of children and adolescents. One way to make sure that children and adolescents eat breakfast on a regular basis is to serve it at school. Several published reviews have examined the effects of eating breakfast and studied effects of school breakfast programmes on children and adolescents. Informed decisions of whether to promote eating breakfast or to introduce a school breakfast programme require a broader perspective. The aim was to conduct a systematic review of scientific publications that study the effects potentially relevant for economic evaluations of eating breakfast or implementing school breakfast programmes for children and adolescents. Method: In the systematic literature review, studies were identified by searching the electronic databases PubMed, CINAHL, Web of Science and PsycINFO from January 2000 through October 2017. The following inclusion criteria guided the selection of the identified studies: published articles from peer-reviewed journals with full text in English, studies collecting primary data, quantitative studies, studies performed in countries comparable to Sweden in terms of access and quality of nutrients, economic and social conditions and publications studying at least one of the topics; academic achievement, quality of life and wellbeing, risk factors/morbidity or cognitive performance. Results: Twenty-six studies on eating breakfast and eleven studies on school breakfast programmes fulfilled the inclusion criteria and were judged to be of at least moderate quality were included in the analysis. The results of the review of studies on eating breakfast showed positive and conclusive effects on cognitive performance, academic achievement, quality of life, well-being and risk factors/morbidity. This indicates that eating breakfast is important. The results of the studies on school breakfast varied. Minor positive effects were seen on cognitive performance and academic achievement. Most studies showed no effects and all studies suffered from different methodological weaknesses. Conclusions: The overall assessment of the studies on eating breakfast indicated positive effects. The studies on school breakfast programmes showed minor positive effects, but the majority of the studies showed no

effects and all studies suffered from different methodological weaknesses. In order to assess the cost-effectiveness of eating breakfast and of school breakfast programmes we need to know more about how the identified affects influence the societal cost and the individuals gain in quality-adjusted life years both in the short and the long term.

CONCLUSION (IN SWEDISH)
Bakgrund: Frukost beskrivs ofta som dagens viktigaste måltid och flera studier har visat att kostintag har en positiv effekt på barn och ungdomars såväl fysiska som mentala utveckling. Ett sätt att öka barn och ungdomars frukostintag är att servera frukost på skoltid. Idag finns flera publicerade översiktsatiklar som har granskat effekterna av att äta frukost såväl som effekterna av skolfrukostprogram. För att kunna fatta ett beslut om huruvida man ska lägga resurser på att främja frukost-ätande eller servera frukost på skoltid krävs dock ytterligare information. Syftet med rapporten är att systematiskt granska de vetenskapliga publikationer som studerar effekter av att äta frukost eller effekter av implementering av skolfrukostprogram potentiellt relevanta att inkludera i en ekonomisk utvärdering. Metod: En systematisk litteratursökning genomfördes. Studierna identifierades genom att söka de elektroniska databaserna PubMed, CINAHL, Web of Science och PsycINFO från januari 2000 till oktober 2017. De inklusionskriterier som tillämpades var: artiklar på engelska publicerade i granskade tidskrifter, artiklar som presenterar primärdata, kvantitativa studier, studier jämförbara med Sverige gällande näringsintag, ekonomiska och sociala förhållanden samt publikationer som studerar minst ett av ämnena; akademisk prestation, livskvalitet och välbefinnande, riskfaktorer/morbiditet eller kognitiv prestanda. Resultat: Tjugosex artiklar som studerade effekter av att äta frukost samt elva studier som studerade effekter av skolfrukostprogram uppfyllde de uppsatta inklusionskriterierna och bedömdes vara av minst måttlig kvalitet inkluderades i analysen. Studierna som studerade effekter av att äta frukost var samstämmiga. De visade att frukostätande hade positiva effekter på kognitiv prestanda, akademisk prestation, livskvalitet och välbefinnande samt på morbida riskfaktorer. Artiklar som studerade effekter av skolfrukostprogram visade på varierande resultat. Ett fåtal studier fann att skolfrukostprogram hade positiva effekter på kognitiv prestanda och akademisk prestation men majoriteten av studierna kunde inte påvisa några effekter. Flertalet av studierna var dock behäftade med metodologiska svagheter. Slutsats: Äta frukost har överlag positiva effekter på de studerade utfallsmåtten. Skolfrukostprogram har små till måttliga effekter på de studerade utfallsmåtten. Majoriteten av studierna som undersökte skolfrukostprogram visade dock inga effekter och alla studier var
6
behäftade med metodologiska svagheter. För att kunna bedöma kostnadseffektiviteten av att äta frukost och skolfrukostprogram, behöver vi mer kunskap om hur de identifierade effekterna påverkar samhällets kostnader och en individs livskvalitet och levnadsår, på såväl kort som lång sikt.

1. BACKGROUND
Breakfast is often described as the most important meal of the day. Overall, eating breakfast on a regular basis is linked to a range of beneficial health outcomes in adults, including improved cognition, physical activity, and lower risk of hypertension [2-4]. Moreover, several studies have focused on examining if breakfast habits have any bearing on school attendance, academic achievement and general health in children and adolescents. Research findings indicate that the regularity of wholesome, daily meal patterns comprised of healthy foods is important for the physical and mental development of children and adolescents [5]. The quality and regularity of breakfast consumption have also shown to be associated with mental performance, academic achievement, physical activity and quality of life [6-12]. Despite this, young people often skip breakfast [13], and the prevalence of children and adolescents skipping breakfast is increasing [14]. In addition, it has been shown that breakfast skipping is particularly common amongst children of lower socioeconomic status [15]. One way to make sure that children and adolescents eat breakfast on a regular basis is to serve it at school. A School Breakfast Programme (SBP) aims to provide a healthy breakfast in school, to improve e.g. nutrition and academic performance [16]. SBP is commonly supervised by staff, offering school children a nutritious breakfast at school before going to class [17]. A variant of SBP is Breakfast in Classroom (BIC). With BIC, students get breakfast in their classroom at the beginning of the school day, rather than in the cafeteria before school start. In addition to research studying the effects of eating breakfast (EB), there is a growing body of literature that aims to measure the effects of School Breakfast Programmes (SBP). Several published reviews have examined the effects of EB and SBP on children and adolescents [18-21]. Informed decisions of whether to promote eating breakfast or to introduce a school breakfast programme require a broader perspective. Since societal resources are scarce, and the needs are endless, choices between health interventions must be made. Economic evaluation of different interventions seeks to identify and quantify the costs and consequences of each alternative for well-founded and informed decision-making.
8
Economic evaluations are comparative analyses of alternative courses of action in terms of both costs and consequences. The costs are weighed against the health effects measured in such a way that it corresponds to a value, usually quality adjusted life-years (QALYs). This measure should ideally encapsulate the impact of an intervention on a person’s length of life, and the impact on their health-related quality of life which is recognized as an important indicator of treatment outcomes. To our knowledge there are no published economic evaluations of EB and SBP. In the absence of cost-effectiveness studies, and as a starting point for future economic assessments, this review will focus on studies that measure outcomes that directly or indirectly can be transformed into QALYs that are traditionally used in cost-effectiveness analysis. The aim was to conduct a systematic review of scientific publications that study the effects potentially relevant for economic evaluations of eating breakfast or implementing school breakfast programmes for children and adolescents.

2. METHOD
Studies were identified by searching the electronic databases PubMed, CINAHL, Web of Science and PsycINFO between January 2000 and October 2017.
To capture all relevant articles published in the field, two different search strategies were constructed. See table 1.
Table 1. Search strategies. Search strategy 1 Breakfast AND Children OR Adolescents OR Teen OR Youth OR students OR kids OR pupils AND Behavior OR Mental OR Learning OR Effect OR Cognitive OR Academic OR Achievement OR Performance OR Well-being OR Quality of life OR Health Search strategy 2 School AND Breakfast AND Children OR Adolescents OR Teen OR Youth OR students OR kids OR pupils AND Behavior OR Mental OR Learning OR Effect OR Cognitive OR Academic OR Achievement OR Performance OR Well-being OR Quality of life OR Health
2.1 Selection of studies
The overall inclusion criteria applied were:
Published articles from peer-reviewed journals with full text in English.
Studies collecting primary data. Quantitative studies. Studies performed in countries comparable to Sweden in terms of
access and quality of nutrients, economic and social conditions. Studies using well defined and valid measures of breakfast
consumption. Publications studying at least one of the following topics:
Academic achievement Quality of life and Well-being
10
Morbidity risk factors Cognitive performance
The association between eating breakfast and weight-related outcomes is a thoroughly studied topic with broad coverage in previous literature [22-24]. The established links for utilizing weight-related outcome measurements in cost-effectiveness analysis highlight the redundancy of further examinations of this association. Weight-related outcomes are therefore omitted from the EB section of this review [25, 26]. The review of SBP studies included studies using weight/obesity as outcome.
One of the authors (ML) conducted the search in October 2017. Initially, two of the authors (ML, NEV) read all titles and abstracts of the identified studies to determine the relevance of each article. If title and abstract met with the inclusion criteria, the study proceeded to the next stage of the review process. Studies with insufficient information in title and abstract also proceeded to the next stage of the review process. After this selection, all authors (ML, L-ÅL, NEV) read the remaining studies in full text, in order to confirm inclusion eligibility and to conduct the quality assessment.
2.2 Quality assessment
In pairs, the authors read the articles in full to assess both eligibility and scientific quality. If the two authors who made the initial assessment did not agree, the third author also read the article. The scientific quality assessment was based on the following criteria: adequate control group(s), randomization, sufficient statistical power, control of confounders, sufficient descriptions of experimental design, relevance of outcome measures and consistency between reported results and conclusions [27, 28]. In order not to let the results of the study affect the quality assessment, this was done separately without, as far as possible, reading the study results. The criteria for quality assessment varied with different study types. The quality of the studies was rated as high, moderate or low. A study rated ‘high quality’ had to fulfill all the quality criteria. Studies of moderate quality fulfilled several of the criteria. Finally, low-quality studies either failed to meet several of the criteria or had major shortcomings in certain criteria. Studies rated as being of high or moderate quality were included in the further analysis. The low-
11
quality studies were excluded. They are presented with a comment in Appendix 1. Tables 2 and 3 contain the following information from the included studies: reference, participant characteristics (number, age, gender), study design, study purpose, outcomes, authors conclusions and the scientific quality assessment.
2.3 Result compilation
A compilation of the study results based on statistical inference is presented in tables 4 and 5. A study was deemed positive if it had at least one statistically significant positive outcome measure; a study was deemed negative if it had at least one statistically significant negative outcome and a study was deemed ‘no effect’ if it showed no statistically significant results. A two-tailed p-value of 0.05 was considered statistically significant.

3. RESULTS
The flow chart in figure 1 illustrates the work process. Database searches identified 5,200 articles. No articles were identified through other types of article sources. After removal of duplicates, 2,958 unique articles remained. Exclusion based on information given in title and abstract resulted in the removal of 2,830 articles. Full-text articles were categorized as “Effect of Eating Breakfast” (EB) or “Effect of School Breakfast Programmes” (SBP). The full-text reading of the EB articles resulted in the additional exclusion of sixteen articles that did not meet the inclusion criteria, and eight were excluded due to low quality. Full-text reading of the SBP articles excluded 63 articles that did not meet the inclusion criteria, and three were excluded due to low quality. Finally, 26 EB articles and 11 SBP articles met the inclusion criteria and remained for further analysis. The 26 EB studies included in the analysis are summarized in table 2, and the 11 SBP studies included in the analysis are presented in table 3.

3.1 Studies of Eating Breakfast
In total, 26 studies were included in the analysis. All studies were published between 2003 and 2017. The countries represented were the UK (seven studies), the US (three studies), Canada, Norway, Australia, Sweden (two studies each), and Denmark, Germany, Italy and the Netherlands (one study each). Four studies were multinational. Most of the studies included were observational. Five were randomized controlled trials, one was a non-randomized trial and one used a separate-group design. The number of participants included in the studies varied from 29 to 28,608. Based on the predetermined inclusion criteria, they all study children and adolescents. The majority studied adolescents [12, 29-31, 33, 35-39, 41-50, 52, 53]. Only four studied children with a mean age below ten years [32, 34, 40, 51]. The studies included a variety of outcome measures and instruments. Based on the applied criteria, studies were divided into four categories. Studies of morbidity risk factors associated with eating or not eating breakfast were most common [29-37]. In addition, studies of links between breakfast and academic achievement were frequent [12, 47-53]. In six studies, the association between breakfast eating and cognitive disorders was analyzed [38-43]. Finally, in three studies the link between breakfast eating and QoL and/or well-being was studied [44-46]. No study concerning the cost-effectiveness of eating breakfast was found. Table 4 shows a compilation of the EB study results.
3.1.1 Morbidity risk factors
All the studies that had morbidity risk factors as outcomes were observational studies. Most of the studies examined the association between breakfast consumption and the metabolic syndrome. Marlatt et al. found that higher levels of breakfast consumption were significantly associated with lower risk for insulin resistance as well as other risk factors for metabolic syndrome [30]. This is in line with what both Sese et al. and Wennberg et al. concluded in their studies [33, 36, 37]. The two studies conducted by Wennberg et al. were longitudinal with 27 years of follow-up. In both studies, they found an association between poor breakfast habits and future risk of developing metabolic syndrome. Hallstrom et al. studied the association between breakfast consumption
29
and cardiovascular disease risk factors. Their results indicated that adolescents who regularly consumed breakfast had higher cardiorespiratory fitness and lower total adiposity [29]. However, they did not find any significant effect of breakfast consumption on blood lipid levels, blood pressure or insulin resistance, in females. Two studies examined the association between breakfast skipping and headache [31, 35]. Both found that irregular breakfast eating is associated with headache.
3.1.2 Cognitive performance
A various number of instruments and test were used to measure cognitive performance among the studies included. All of them found that eating breakfast has positive effects on cognitive performance. Wesnes et al. concluded in both their studies that breakfast improved children’s attention [41, 42]. Cooper et al. found that eating breakfast had particularly beneficial effects when study participants faced more cognitively demanding tasks [38]. They also measured self-reported tension and calmness between the breakfast and no breakfast groups, but found no difference. In addition, they found that breakfast consumption improved response time measured with Sternberg paradigm, a memory-scanning task for short term memory testing. This effect was not possible to confirm with other similar tests measuring response time. Wesnes et al. also showed that breakfast affects response speed variability. Participants who had breakfast showed lower response speed variability. Hjorth et al. and Widenhron-Müller used the d2-test to measure selective and sustained attention and visual scanning speed. Hjorth et al. found a positive interaction between breakfast consumption and d2-test results [40]. Widenhorn-Müller showed beneficial effects of breakfast on short-term memory and mood but not on sustained attention [43].
3.1.3 Quality of life and Well‐being
All of the included studies used different measurements to study the association between breakfast consumption and QoL and/or well-being. However, the results are consistent. Page et al. found that eating breakfast was one of twelve significant predictors of self-rated health measures [44]. Richards and Smith provided evidence showing that stress, anxiety and depression were associated with skipping breakfast [45]. Nevertheless, they highlighted the possibility that mental health might influence whether a person consumes breakfast or not. Smith et al. also found that breakfast consumption is linked to increased well-being [46].
30
3.1.4 Academic achievement
All the studies that investigated breakfast consumption and academic achievement found positive associations between breakfast consumption and academic achievement. In a study conducted by Lien in Norway, the implications of skipping breakfast on mental distress and academic achievement were stronger for boys than girls and were stronger for native Norwegians than immigrants [50]. Burrows et al. concluded that dietary behavior overall was associated with higher academic achievement, but that breakfast was only significantly associated with the domain writing [48].

3.2 Studies of School Breakfast Programmes
In total, 11 studies were included in the analysis. The studies were published between 2002 and 2016. The countries that were represented were the US (eight studies), the UK (two studies), and New Zealand (one study). The number of participants included in the studies varied from 97 to 723,843. The age of the participants in the studies varied. Most of them examined children and adolescents in a range of ages using data from different grades. Ribar et al. and Hofferth and Curtin studied children that were a bit younger (between 6-12 years). Seven studies were observational studies [55-57, 59, 62-64]. Two were randomized controlled trials and the remaining two used pre-post design. Most of the studies compared regular SBP participation with non-participation. However, a few had slightly different approaches. Ribar et al. examined changes from universal free school breakfast programmes to eligibility-based programmes, which is quite different from previous studies which only investigated intervention changes in the opposite direction. The majority of the studies examined the effects of SBP. Corcoran et al. examined BIC. Anzman-Frasca et al. compared BIC with non-BIC schools (where non-BIC schools offered traditional SBP). The identified outcome measures used in the studies included were cognitive performance, academic achievement and weight/obesity. Studies of academic achievement were most common. No studies of the association between QoL and/or well-being and SBP were identified. Nor did any studies examine the association between SBP and different morbidity risk factors. Furthermore, no study of the cost-effectiveness of SBP was identified. Table 5 shows a compilation of the SBP study results.
3.2.1 Cognitive performance
Moore et al. used several different outcomes to study the effect of free SBP compared to non-free SBP [54]. They found that free SBP had no effect on episodic memory but concluded that SPB might reduce socio-economic inequalities in terms of breakfast skipping. Shemilt et al. also studied several outcome measures [55]. They showed that SBP improved

concentration and reduced the number of days the adolescents skipped classes and school.
3.2.2 Academic achievement
Studies of the association between SBP and academic achievement showed varied results. Anzman-Frasca et al., Corcoran et al., Leos-Urbel et al. and Mhurchu et al. all concluded that serving breakfast had no effect on educational outcomes. Mhurchu et al. found that SBP had no effects on children’s school attendance rates but had significant positive effects on children’s short-term satiety ratings [60]. More specifically, Leos-Urbel et al. examined meal programme participation, student attendance and standardized mathematics and reading test scores [59]. They found no impact on educational outcomes from meal programme participation. However, results indicated that universal free SBP increased participation among children previously eligible to free school breakfast. Anzman-Frasca et al. also showed that participation rates were greater in BIC schools compared to non-BIC schools, and found an association between BIC participation and improved overall school attendance rates [56]. However, as stated above, they found no difference regarding performance in mathematics and reading in the group that received BIC versus the group that did not. Kleinman et al. differed from the other studies [58]. They found that students participating in SBP enhanced their daily nutritional intake and found an association with significant improvements in academic performance. Ribar et al. had a slightly different approach [61]. They studied if switching from a free to an eligibility-based SBP reduced participation. They found that it led to substantially reduced participation rates. However, they found no evidence that the reduced participation harmed test scores or attendance.
3.2.3 Weight/Obesity
Three of the studies used weight/obesity as outcome measure. In principle, all three studies agreed. Gleason & Dodd found no evidence that SBP participation contributes to childhood obesity [62]. Hofferth & Curtin also found no evidence that food programmes contribute to overweight in children from poor families [63]. Sudharsanan et al. reported that for most children, receiving school breakfast was unrelated to obesity [64]. However, SBP participation in 5th grade was possibly
33
associated with weight gain between 5th and 8th grade, for children from families in poverty compared to children of similar socioeconomic status that did not receive breakfast. The study conducted by Corcoran et al. also used weight/obesity as outcome measure [57]. In line with the other studies, they found no association of excessive weight gains or obesity rates from BIC.

4. DISCUSSION
This review searched for studies examining the effects of eating breakfast (EB) and of school breakfast programmes (SBP) respectively. Throughout the review, the results of the two searches were handled separately. The EB studies included focused mainly on studying the effects of eating breakfast versus not eating breakfast; divided into four categories of study outcomes. Similarly, the range of study outcomes in the SBP studies were divided into three outcome categories. All studies included in the analysis met the inclusion criteria of this review and were judged to be of at least moderate quality. Consequently, the excluded studies either failed to meet the inclusion criteria or had a low study quality rating. There was a notable variation in study design across the studies. In general, studies were either of observational or experimental design. The strongest study design for drawing causal relationship is the randomized controlled trial. Observational studies are important and common but also vitiated by several limitations. This is important to keep in mind when interpreting and assessing the value of the results presented in observational studies. For instance, it is problematic to assign the effects of eating breakfast to its sole nutritional value. Whether children eat breakfast or not and whether it has any substantial effect on study outcomes might very well be derived from a large number of unobserved influential factors, such as the children’s social environment and parental support. Variation in the studied type of breakfast intervention also differed. In the SBP category, each intervention had a unique design. The interventions could include Breakfast In Classroom (BIC), universal-free school breakfast programme, extended availability and serving capacity of school breakfast, and the launch of information campaigns to promote breakfast eating to schoolchildren, their parents and staff. It was not possible to draw any definite conclusions regarding the importance of how the breakfast is served. However, possible mechanisms related to the serving of breakfast are discussed below. The results of the SBP studies varied. A few studies showed that SBP had minor positive effects regarding cognitive performance and academic achievement. Studies examining the association between SBP and weight/obesity showed both positive and negative effects. However, the majority of the studies found no effects at all. In addition, no studies examined the effects of SBP on quality of life, well-being and morbidity
35
risk factors. Two of eleven SBP studies examined the effects of BIC. Both studies found that BIC improved the overall participation rate compared to SBP [56, 57]. Breakfast access can be facilitated when served in the classroom, reaching students who otherwise are unlikely to participate. However, based on the two studies included in this review it is difficult to draw any firm conclusions regarding this. Moreover, none of these studies showed any effects in any of our outcome topics. Leos-Urbel et al. found that universal-free SBP increased participation rates primarily among those who previously skipped eligibility-based school breakfast. The increased participation rates were driven by social mechanisms, as the stigma of receiving eligibility-based SBP vanished. These studies highlight reasons for introducing universal-free SBP interventions. Eligibility-based SBPs that target individual schoolchildren in need of interventional support may therefore prove unsuccessful. This supports the conclusion of Moore et al., that universal-free SBP might reduce socio-economic inequalities among schoolchildren. Many of the SBP studies included suffered from methodological weaknesses. This could potentially explain the thin set of observable effects. Whether the detected associations were of a causal nature remains unanswered, since few studies were randomized controlled trials. The most common shortcoming among the SBP studies was the lack of confounder control. For example, the recurring lack of control for whether the children had breakfast at home or elsewhere. The review of EB studies showed positive and conclusive effects on cognitive performance, academic achievement, quality of life, well-being, and morbidity risk factors. This is clear evidence that eating breakfast is important. The consistently positive results may indicate different forms of bias. There is always a risk of publication bias that could contaminate this type of review, which could have overestimated the strength of the evidence [65]. In addition, it is also possible that authors facing non-significant results can tweak the hypothesis to better suit data. This is known as HARKing – hypothesizing after the results are known [66]. Also, the lack of control for confounders in the EB studies may have affected the results. As it is not possible to adjust for all confounders, it is difficult to establish a clear causal link between intervention and outcome [67]. EB studies that examine the association between breakfast and weight/obesity has been thoroughly studied and reviewed before. Therefore, such studies were excluded from this review. However, despite the exclusion of the weight/obesity effects of eating breakfast in this review, it should be noted that it is relevant to include weight/obesity in economic evaluations of breakfast.
36
To conduct this review, several considerations and restrictions had to be applied. Including only studies from regions comparable to Sweden restricted the study catchment area to Europe and North America, plus Australia and New Zealand. The potential exclusion of relevant studies from other nations is one limitation. In the assessment of study quality, the risk of incorrect classification is contingent. Although, by proactively disregarding the study results in the articles included when performing quality assessment, the authors took measures to limit the risk of study quality misclassification. Studies of breakfast attract researchers from different discipline. In part, this explain the high diversity in designs of SBP interventions, the multiple definitions and the measurement methods used in studying EB. Often, systematic reviews include a meta-analysis component. Meta-analysis uses statistical methods to synthesis data from the systematic review into a single quantitative outcome. Pooling results from different instruments and outcomes may lead to between-study heterogeneity and biased meta-analysis [68]. Therefore, meta-analysis of this research area is currently unwarranted. Our interest in finding and valuing the effects that can be attributed to breakfast eating and SBP emanates from the question of the cost-effectiveness of breakfast interventions. Our study cannot answer that question, but shows that breakfast eating and SBP do have effects that could be used in economic evaluations, especially when using decision analytic modeling, calculating the long-term cost and effects of intervention. For instance, improved cognitive performance and academic achievements may influence long-term effects on an individual’s productivity through improved school results, grades, higher education. Further, this gives higher human capital, which can be reflected in higher income, both for the individual and for society. Improvements in quality of life and well-being will have an immediate effect on the child’s/adolescent’s QALY weight but also, if the effects are sustained, on the long-term QALY gain. Finally, the health effects mediated by a reduction of long-term morbidity risk factors such as obesity, will contribute to lower morbidity/mortality and a reduction in health care costs. In order to answer the questions regarding cost-effectiveness of breakfast and interventions promoting breakfast, we need to know more about how the identified effects influence the societal cost and the individual’s QALY gain. There is also a need to develop models that can simulate breakfast interventions long-term costs and effects. In this study, we have started that work by identifying important model parameters.

5. CONCLUSIONS
The overall assessment of the eating breakfast studies indicated positive effects in cognitive performance, academic achievement, quality of life and well-being, and reduced long-term morbidity risk factors.
The school breakfast programmes studied showed minor positive effects regarding cognitive performance, academic achievement, with mixed impact on weight/obesity. However, most studies showed no effects, and all studies suffered from different methodological weaknesses.
Universal-free SBP, such as BIC, may lead to increasing participation rates. Uncertainty remains whether it has any impact on school attendance rates and socio-economic inequalities.
In order to answer the questions regarding cost-effectiveness of breakfast and breakfast interventions, we need to know more about the long-term effects of the interventions.
