Abstract
BACKGROUND Overconsumption of food, alcohol, and tobacco products increases the risk of non-communicable diseases. Interventions to change characteristics of physical micro-environments where people may select or consume these products - including shops, restaurants, workplaces, and schools - are of considerable public health policy and research interest. This review addresses two types of intervention within such environments: altering the availability (the range and/or amount of options) of these products, or their proximity (the distance at which they are positioned) to potential consumers. OBJECTIVES 1. To assess the impact on selection and consumption of altering the availability or proximity of (a) food (including non-alcoholic beverages), (b) alcohol, and (c) tobacco products.2. To assess the extent to which the impact of these interventions is modified by characteristics of: i. studies, ii. interventions, and iii. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, PsycINFO, and seven other published or grey literature databases, as well as trial registries and key websites, up to 23 July 2018, followed by citation searches. SELECTION CRITERIA We included randomised controlled trials with between-participants (parallel group) or within-participants (cross-over) designs. Eligible studies compared effects of exposure to at least two different levels of availability of a product or its proximity, and included a measure of selection or consumption of the manipulated product. DATA COLLECTION AND ANALYSIS We used a novel semi-automated screening workflow and applied standard Cochrane methods to select eligible studies, collect data, and assess risk of bias. In separate analyses for availability interventions and proximity interventions, we combined results using random-effects meta-analysis and meta-regression models to estimate summary effect sizes (as standardised mean differences (SMDs)) and to investigate associations between summary effect sizes and selected study, intervention, or participant characteristics. We rated the certainty of evidence for each outcome using GRADE. MAIN RESULTS We included 24 studies, with the majority (20/24) giving concerns about risk of bias. All of the included studies investigated food products; none investigated alcohol or tobacco. The majority were conducted in laboratory settings (14/24), with adult participants (17/24), and used between-participants designs (19/24). All studies were conducted in high-income countries, predominantly in the USA (14/24).Six studies investigated availability interventions, of which two changed the absolute number of different options available, and four altered the relative proportion of less-healthy (to healthier) options. Most studies (4/6) manipulated snack foods or drinks. For selection outcomes, meta-analysis of three comparisons from three studies (n = 154) found that exposure to fewer options resulted in a large reduction in selection of the targeted food(s): SMD -1.13 (95% confidence interval (CI) -1.90 to -0.37) (low certainty evidence). For consumption outcomes, meta-analysis of three comparisons from two studies (n = 150) found that exposure to fewer options resulted in a moderate reduction in consumption of those foods, but with considerable uncertainty: SMD -0.55 (95% CI -1.27 to 0.18) (low certainty evidence).Eighteen studies investigated proximity interventions. Most (14/18) changed the distance at which a snack food or drink was placed from the participants, whilst four studies changed the order of meal components encountered along a line. For selection outcomes, only one study with one comparison (n = 41) was identified, which found that food placed farther away resulted in a moderate reduction in its selection: SMD -0.65 (95% CI -1.29 to -0.01) (very low certainty evidence). For consumption outcomes, meta-analysis of 15 comparisons from 12 studies (n = 1098) found that exposure to food placed farther away resulted in a moderate reduction in its consumption: SMD -0.60 (95% CI -0.84 to -0.36) (low certainty evidence). Meta-regression analyses indicated that this effect was greater: the farther away the product was placed; when only the targeted product(s) was available; when participants were of low deprivation status; and when the study was at high risk of bias. AUTHORS' CONCLUSIONS The current evidence suggests that changing the number of available food options or altering the positioning of foods could contribute to meaningful changes in behaviour, justifying policy actions to promote such changes within food environments. However, the certainty of this evidence as assessed by GRADE is low or very low. To enable more certain and generalisable conclusions about these potentially important effects, further research is warranted in real-world settings, intervening across a wider range of foods - as well as alcohol and tobacco products - and over sustained time periods.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16091605. [PMID: 31071922 PMCID: PMC6540591 DOI: 10.3390/ijerph16091605] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 04/26/2019] [Accepted: 04/30/2019] [Indexed: 11/16/2022]
Abstract
The aim of this paper is to report on the lunchtime food purchasing practices of secondary school students and some of the factors related to this purchasing, including the influence of socio-economic status (SES) and the food environment within and around schools. A mixed-methods study incorporating an online purchasing recall questionnaire and multiple qualitative methods was undertaken at seven UK secondary schools. The analysis shows that SES was intricately woven with lunchtime food practices. Three-quarters of participants regularly purchased food outside of school; those at low SES schools were more likely to report regularly leaving school to buy food. Young people’s perception of food sold in schools in areas of low SES was often negative and they left school to find “better” food and value for money. Taste, ingredients and advertisements were factors that mattered to young people at schools with low or mixed SES; health as a driver was only mentioned by pupils at a high SES school. For public health initiatives to be effective, it is critical to consider food purchasing practices as complex socio-economically driven phenomena and this study offers important insights along with suggestions for designing interventions that consider SES. Availability of food outlets may be less important than meeting young people’s desires for tasty food and positive relationships with peers, caterers and retailers, all shaped by SES. Innovative ways to engage young people, taking account of SES, are required.

Abstract
PURPOSE The purpose of this article is to examine the effect of a school-based nutrition intervention using an ecological approach to improve adolescents' nutrition-related knowledge, attitudes and behaviour in rural China. METHODS A cluster-randomised intervention trial design was employed. Two middle schools were randomly selected and assigned to the school that was conducting a holistic school-based intervention using health-promoting school (HPS) framework, 'HPS School', or to the 'Control School' in Mi Yun County, Beijing. From each school we randomly selected 65 seventh-grade students to participate in the study. Their nutrition-related knowledge, attitudes and behaviour were measured by pre- and post-intervention surveys with the same instrument. The nutrition intervention lasted for six months. RESULTS Adolescents in the intervention school were more likely to know the nutrition knowledge items, with an odds ratio (OR) ranging from 1.86 (95% confidence interval (CI): 1.11-3.09) to 6.34 (95% CI: 3.83-10.47); more likely to think nutrition is very important to health, developing healthy dietary habits is very important, and that expired foods should be thrown away, with ORs of 3.03 (95% CI: 1.60-5.76), 2.76 (95% CI: 1.66-4.59) and 2.35 (95% CI: 1.33-4.17) respectively, and more likely to consume no soft drinks, desserts or fried food, and to eat vegetables every day of the last week, with ORs of 1.99 (95% CI: 1.31-3.04), 3.96 (95% CI: 2.43-6.46), 3.63 (95% CI: 2.26-5.85), and 2.51 (95% CI: 1.41-4.48) respectively, as compared with those in the control school after interventions. CONCLUSIONS Our intervention using the HPS framework, an ecological approach, was an appropriate model to promote nutrition among adolescents in rural China and its use should be advocated in future school-based nutrition promotion programmes for adolescents.

Abstract
School-based interventions are relatively new and were first introduced in the United States in the 1990s. Early programs were mainly education based with many of the findings now embedded in school policy in the form of a healthy eating curriculum. More recent school programs have taken education outside the classroom and attempted to engage parents as well as teachers. Environmental changes such as improving the quality of foods available at lunchtime and at other times during the school day are now common. Reviews of evaluations of school-based programs have demonstrated that they are effective and successfully improve dietary quality such as increasing fruit and vegetable intake and decreasing sweet and savory snacks and sweetened drinks; not just in school but over the whole day and particularly in younger school children. School-based interventions are also effective at reducing obesity if components to increase physical activity and reduce sedentary behaviors are also targeted but not if only dietary behaviors are tackled. Most of the high-quality evaluation studies using randomized controlled trials have been carried out in high-income countries as they are costly to run. However, middle-income countries have benefitted from the information available from these evaluation studies and many are now starting to fund and evaluate school-based programs themselves, resulting in unique problems such as concomitant under- and overnutrition being addressed. Action for the future demands more focus on populations most at risk of poor dietary quality and obesity in order to reduce inequalities in health and on adolescents who have not benefited as much as younger children from school-based interventions. This will involve innovative solutions within schools as well as targeting the food environment outside schools such as reducing the density of fast-food outlets and marketing of sweet and savory snacks and drinks.

Abstract
This report describes a regional approach for improving the nutritional quality of school meals and increasing the selection of healthier foods. Let's Go! is a childhood obesity prevention program that establishes regional workgroups to develop innovative solutions to improve school meal programs. Let's Go! fosters collaborative decision making, specifically addressing the feasibility of proposed strategies, differences in school environments, and level of readiness for change. This approach led to 77 schools achieving the HealthierUS School Challenge and 130 schools implementing Smarter Lunchrooms techniques in school year 2011-2012. Communities nationwide could use a similar approach to improve school meals.

Abstract
Evidence for effectiveness of school-based studies for prevention of adolescent obesity is equivocal. Tailoring interventions to specific settings is considered necessary for effectiveness and sustainability. The PRECEDE framework provides a formative research approach for comprehensive understanding of school environments and identification of key issues/areas to focus resources and energies. No reported studies have tested applicability of the PRECEDE framework in schools in relation to obesity. Adolescents (n = 362), parents (n = 349) and teachers (n = 146) from six secondary schools participated in two quantitative studies and two qualitative studies. Data collected from these studies permitted confirmation of adolescent overweight/obesity a health issue for schools; the need for secondary schools to focus health promotion efforts on healthy nutrition, with inclusion of parents/homes and appreciation for gender differences in developing interventions. Community buy-in and commitment to school-based obesity prevention programs may be dependent on initially addressing what may be perceived as minor issues, and developing policies to guide practices within schools in relation to supply and access to healthy foods, use of sporting equipment and participation in physical activities. The PRECEDE framework allows systematic assessment of school environments and provided opportunity to identify realistic and relevant interventions for promoting healthy adolescent physical activity and nutrition behaviors.

Abstract
Background Low fruit and vegetable (FV) consumption is one of the top 10 global risk factors for mortality, and is related to increased risk for cancer, cardiovascular disease and diabetes. Many environmental, sociodemographic and personal factors affect FV consumption. The purpose of this review is to examine the effects of interventions delivered in the home, school and other nutritional environments designed to increase FV availability for five to 18-year olds. Methods The search included: 19 electronic bibliographic databases; grey literature databases; reference lists of key articles; targeted Internet searching of key organization websites; hand searching of key journals and conference proceedings; and consultation with experts for additional references. Articles were included if: in English, French and Spanish; from high-, middle-, and low-income countries; delivered to anyone who could bring about change in FV environment for 5 to 18 year olds; with randomized and non-randomized study designs that provided before-after comparisons, with or without a control group. Primary outcomes of interest were measures of FV availability. Results The search strategy retrieved nearly 23,000 citations and resulted in 23 unique studies. Interventions were primarily policy interventions at the regional or state level, a number of curriculum type interventions in schools and community groups and a garden intervention. The majority of studies were done in high-income countries. The diversity of interventions, populations, outcomes and outcome measurements precluded meta-analysis. The most promising strategies for improving the FV environment for children are through local school food service policies. Access to FV was successfully improved in four of the six studies that evaluated school-based policies, with the other two studies finding no effect. Broader state or federally mandated policies or educational programs for food service providers and decision makers had mixed or small impact. Similarly family interventions had no or small impact on home accessibility, with smaller impact on consumption. Conclusions The studies have high risk of bias but more rigorous studies are difficult to impossible to conduct in naturalistic settings and in policy implementation and evaluation. However, there are promising strategies to improve the FV environment, particularly through school food service policies.

Abstract
OBJECTIVE The emphasis in school nutrition policy has been on vending and competitive items. Our study was designed to characterize and quantify the amount and source of other foods and beverages on school campuses. DESIGN A cross-sectional observational study was conducted using a specially designed objective nutrition observation system. SETTING One low-income school district in southern California with six elementary and two middle schools. SUBJECTS Data were not collected from individual children. A total of 4033 students, 42 % of whom were Hispanic/Latino, 26 % African American and 21 % non-Hispanic white, were observed across school settings. RESULTS Data were collected continuously from 9 January 2008 to 16 June 2010. Healthy foods had, per serving, total energy ≤732 kJ (≤175 kcal), total fat content ≤35 %, total saturated fat ≤10 %, sugar less ≤15 g, sodium <200 mg and trans-fat ≤0·5 g. Healthy beverages were only 100 % juice or water, and unflavoured non-fat, 1 %, 2 % milk and soya or rice milk. The system had high inter-rater reliability (r = 0·78 to 0·99), percentage agreement (83 % to 100 %) and test-retest reliability (r = 0·81 to 0·98). Significantly more unhealthy foods and beverages than healthy items were observed on all campuses (P < 0·001). An average of 1·26 (sd 0·46) items per student per week was found with an average of 0·86 (sd 0·34) unhealthy items per child per week. CONCLUSIONS There were substantial amounts of unhealthy foods and beverages brought onto campuses for classroom rewards, celebrations and fundraising that should be targeted for intervention.

Abstract
Due to adolescents' future crucial roles, their health needs should be included in the national health system policy. In this cross-sectional study 2010 female adolescents were recruited from randomly selected schools in Iran. To obtain their health needs, the participants completed a self-administrated questionnaire. It was revealed that emotional needs were the most important health needs of adolescents. Furthermore, there was a meaningful relationship between health needs' score with the adolescents' age and their mothers' education level. Finally, the mean score of health needs was significantly higher in urban adolescents. Therefore, it is suggested that adolescents' emotional health needs to be paid attention; otherwise irrecoverable serious problems may occur in the next generation's health.

BMC Public Health 2012; 12:711. [PMID: 22931474 PMCID: PMC3505745 DOI: 10.1186/1471-2458-12-711] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2011] [Accepted: 08/23/2012] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Low fruit and vegetable ( FV) consumption is a key risk factor for morbidity and mortality. Consumption of FV is limited by a lack of access to FV. Enhanced understanding of interventions and their impact on both access to and consumption of FV can provide guidance to public health decision-makers. The purpose of this scoping review is to identify and map literature that has evaluated effects of community-based interventions designed to increase FV access or consumption among five to 18-year olds. METHODS The search included 21 electronic bibliographic databases, grey literature, targeted organization websites, and 15 key journals for relevant studies published up to May 2011. Retrieved citations were screened in duplicate for relevance. Data extracted from included studies covered: year, country, study design, target audience, intervention setting, intervention strategies, interventionists, and reported outcomes. RESULTS The search located 19,607 unique citations. Full text relevance screening was conducted on 1,908 studies. The final 289 unique studies included 30 knowledge syntheses, 27 randomized controlled trials, 55 quasi-experimental studies, 113 cluster controlled studies, 60 before-after studies, one mixed method study, and three controlled time series studies. Of these studies, 46 included access outcomes and 278 included consumption outcomes. In terms of target population, 110 studies focused on five to seven year olds, 175 targeted eight to 10 year olds, 192 targeted 11 to 14 year olds, 73 targeted 15 to 18 year olds, 55 targeted parents, and 30 targeted teachers, other service providers, or the general public. The most common intervention locations included schools, communities or community centres, and homes. Most studies implemented multi-faceted intervention strategies to increase FV access or consumption. CONCLUSIONS While consumption measures were commonly reported, this review identified a small yet important subset of literature examining access to FV. This is a critically important issue since consumption is contingent upon access. Future research should examine the impact of interventions on direct outcome measures of FV access and a focused systematic review that examines these interventions is also needed. In addition, research on interventions in low- and middle-income countries is warranted based on a limited existing knowledge base.

Abstract
AbstractObjectiveTo evaluate implementation and effectiveness of nutrition promotion programmes using the health-promoting schools (HPS) approach, to indicate areas where further research is needed and to make recommendations for practice in this field.DesignThe searched electronic databases included: CINAHL, Cochrane Library, Health Reference Center, Informit Search, MEDLINE, ProQuest, PsycINFO, PubMed, ScienceDirect, Scopus, Social Services Abstracts and Web of Science. Inclusion criteria were: (i) controlled or before-and-after studies evaluating a nutrition intervention and involving the HPS approach, either fully or in part; (ii) provision of information about components and delivery of the intervention; and (iii) report on all evaluated outcomes.SettingSchools.SubjectsStudents, parents and school staff.ResultsAll included studies described intervention delivery and six reported on process evaluation. In intervention schools school environment and ethos were more supportive, appropriate curriculum was delivered and parents and/or the community were more engaged and involved. Students participated in interventions at differing levels, but the majority was satisfied with the intervention. The evidence indicates that nutrition promotion programmes using the HPS approach can increase participants’ consumption of high-fibre foods, healthier snacks, water, milk, fruit and vegetables. It can also reduce participants’ ‘breakfast skipping’, as well as reduce intakes of red food, low-nutrient dense foods, fatty and cream foods, sweet drinks consumption and eating disorders. It can help to develop hygienic habits and improved food safety behaviours.ConclusionsMore professional training for teachers in the HPS approach, further qualitative studies, longer intervention periods, improved follow-up evaluations and adequate funding are required for future school-based nutrition promotion programmes.

Abstract
BACKGROUND Food for Fitness is an on-going multi-component health promotion programme, delivered in primary and secondary schools by community nutrition assistants. The programme uses nutritional interventions aimed at promoting healthier eating practices for children. This service evaluation investigated the receipt and delivery of the programme, as perceived by local stakeholders who had experienced and administered the service. METHODS Semi-structured interviews and focus groups were carried out with three key stakeholder groups: health professionals (n = 9), school teachers (n = 10) and senior health officials (n = 3). Qualitative data were transcribed verbatim and received thematic analysis with deductive and inductive processes. RESULTS Stakeholders reported that the programme contributed to the development of food education and healthy-eating practices of children in the local area. Stakeholders considered that the main concern was the limited capacity and size of the service. They described problems with long-term sustainability in supporting schools with maintaining nutritional interventions, highlighting issues regarding contact, planning and organisation of several interventions. CONCLUSIONS The findings of the service evaluation inform service management, organisation and ground-level delivery. The use of stakeholder opinion provided contextualised information on the factors that impact on the implementation of the programme. The richness of the qualitative results can guide future planning and provision for similar health promotion nutrition programmes delivered in the school environment.

Effectiveness of school-based interventions in Europe to promote healthy nutrition in children and adolescents: systematic review of published and ‘grey’ literature. Br J Nutr 2010; 103:781-97.

Abstract
The objective of the present review was to summarise the existing European published and ‘grey’ literature on the effectiveness of school-based interventions to promote a healthy diet in children (6–12 years old) and adolescents (13–18 years old). Eight electronic databases, websites and contents of key journals were systematically searched, reference lists were screened, and authors and experts in the field were contacted for studies evaluating school-based interventions promoting a healthy diet and aiming at primary prevention of obesity. The studies were included if they were published between 1 January 1990 and 31 December 2007 and reported effects on dietary behaviour or on anthropometrics. Finally, forty-two studies met the inclusion criteria: twenty-nine in children and thirteen in adolescents. In children, strong evidence of effect was found for multicomponent interventions on fruit and vegetable intakes. Limited evidence of effect was found for educational interventions on behaviour, and for environmental interventions on fruit and vegetable intakes. Interventions that specifically targeted children from lower socio-economic status groups showed limited evidence of effect on behaviour. In adolescents, moderate evidence of effect was found for educational interventions on behaviour and limited evidence of effect for multicomponent programmes on behaviour. In children and adolescents, effects on anthropometrics were often not measured, and therefore evidence was lacking or delivered inconclusive evidence. To conclude, evidence was found for the effectiveness of especially multicomponent interventions promoting a healthy diet in school-aged children in European Union countries on self-reported dietary behaviour. Evidence for effectiveness on anthropometrical obesity-related measures is lacking.

Abstract
BACKGROUND Valid and reliable measures are required to assess any effect of the food environment on individual dietary behavior, and form the foundation of research that may inform obesity-related policy. Although many methods of measuring the food environment exist, this area of research is still relatively new and there has been no systematic attempt to gather these measures, to compare and contrast them, or to report on their psychometric properties. EVIDENCE ACQUISITION A structured literature search was conducted to identify peer-reviewed articles published between January 1990 and August 2007 that measured the community-level food environment. These articles were categorized into the following environments: food stores, restaurants, schools, and worksites. The measurement strategies in these studies were categorized as instruments (checklists, market baskets, inventories, or interviews/questionnaires) or methodologies (geographic, sales, menu, or nutrient analyses). EVIDENCE SYNTHESIS A total of 137 articles were identified that included measures of the food environment. Researchers focused on assessing the accessibility, availability, affordability, and quality of the food environment. The most frequently used measure overall was some form of geographic analysis. Eighteen of the 137 articles (13.1%) tested for any psychometric properties, including inter-rater reliability, test-retest reliability, and/or validity. CONCLUSIONS A greater focus on testing for reliability and validity of measures of the food environment may increase rigor in research in this area. Robust measures of the food environment may strengthen research on the effects of the community-level food environment on individual dietary behavior, assist in the development and evaluation of interventions, and inform policymaking targeted at reducing the prevalence of obesity and improving diet.

Abstract
The aim of the present investigation was to study the effect of a dietary intervention which combined nutrition information with increased availability of vegetables, fruits and wholegrain bread. The effect of the intervention was determined by changes in the intake of vegetables, fruits, wholegrain bread and estimated nutrients. Furthermore, the study investigated whether changes in relative contribution from different food sources of folate were related to changes in the concentration of plasma total homocysteine (p-tHcy). The 5-month intervention study included 376 male recruits from the Norwegian National Guard, Vaernes (intervention group) and 105 male recruits from the Norwegian National Guard, Heggelia (control group). The study resulted in an increase in the total consumption of vegetables, fruits, berries and juice (P < 0·001) and of wholegrain bread (P < 0·001). The participants in the intervention group showed a higher increase in the intake of dietary fibre (P < 0·001) and folate (P < 0·001) compared with the control group. The relative contribution of folate intake from fruits, vegetables and wholegrain bread was higher in the intervention group compared with the control group (P < 0·001 for all). The increased intake of folate from wholegrain bread was inversely associated with a reduced concentration of p-tHcy (P = 0·017). In summary, the dietary intervention resulted in an increased intake of vegetables, fruits and wholegrain bread and a subsequent increase in folate intake from these food components. Reduction in the concentration of p-tHcy was significantly related to an increased folate intake due to an increased consumption of wholegrain bread.

Abstract
OBJECTIVE To evaluate the nutritional composition of worksite canteen lunches and to examine the impact of two meal serving systems on employee intake, i.e. buffet style with a fixed price for a varied number of dishes and à la carte style with a separate price for each item on the menu. DESIGN Laboratory technicians observed employees' food selection and collected identical dishes. Food items were weighed separately to calculate the content of fruit and vegetables. The content of protein, fat and ash of each dish was chemically analysed and the carbohydrate and energy content calculated. SETTING Fifteen randomly chosen worksite canteens in Denmark: eight canteens serving buffet style and seven canteens with an à la carte line. SUBJECTS one hundred and eighty randomly chosen employees having lunch at the worksite canteens. RESULTS The average percentage energy from fat was 37 +/- 12 among men and 33 +/- 12 among women. No association was found between the meal serving system and energy intake or macronutrient composition. Eating at canteens serving buffet style, on the other hand, was associated with an increased intake of fruit and vegetables, on average 76 g, and a lower energy density of the food for both genders. CONCLUSION The results highlight the possibilities of promoting healthy food choices in the catering sector and the need to identify models of healthy catering practice. Serving buffet style appears to be a promising strategy in order to increase fruit and vegetable consumption in food served away from home.

Abstract
AbstractObjective:To investigate changes in the consumption of fruits and vegetables in work-site canteens using the tools of continuous quality improvement, and to gain knowledge of practical strategies being effective in increasing the consumption.Design:Study design included baseline data collection, an 8 h training session for all canteen staff, goal setting, strategy development and implementation for each canteen, end-point data collection and a follow-up data collection 4 months from the end-point (1 year from baseline). The main outcome measurement was average grams of fruits and vegetables per lunch meal served per customer (net weight; potatoes not included).Setting:Five workplaces in Denmark: a military base, an electronic component distributor, a bank, a town hall and a waste-handling facility.Subjects:Work-site canteen managers, staff and customers.Results:There were significant increases in the total consumption of fruits and vegetables for all five work-site canteens from baseline to end-point, 70 g per customer on average (67, 54, 39, 88 and 103 g, respectively). The follow-up data collection showed that the canteens either maintained or significantly increased consumption, the average increase being 95 g per customer compared with baseline (77, 60, 86, 70 and 183 g, respectively).Conclusions:This study demonstrates a large potential for work-site canteens to increase customers' intake of fruits and vegetables at lunch and suggests a broad spectrum of strategies to compose meals that are both rich in fruits and vegetables and attractive to customers.

Abstract
OBJECTIVE To determine the acceptability of lower glycemic index (GI) foods served at diabetes camp. DESIGN Crossover design of standard and lower GI menus. SETTING Three consecutive 5-day diabetes camp sessions. PARTICIPANTS 140 youth, age 7-16, with type 1 or 2 diabetes. INTERVENTION A standard camp cycle menu was reformulated to include 2 1/2 days of standard foods and 2 1/2 days of lower GI foods. MAIN OUTCOME MEASURES Youth provided satisfaction ratings after meals and snacks using measures designed for this study. Observations of food consumption were conducted on a random sample of youth for each meal. ANALYSIS Descriptive analyses and t-tests were conducted to assess differences in satisfaction with and consumption of standard and lower GI foods. RESULTS Lower GI foods served at dinner and for snacks received satisfaction ratings equal to standard foods (dinner: 3.68 lower GI versus 3.79 standard, P = .30; snacks: 3.74 lower GI versus 3.79 standard, P = .60). Lower GI foods served at breakfast and lunch received lower, though very acceptable, ratings (breakfast: 3.76 lower GI versus 4.04 standard, P < .01; lunch: 3.64 lower GI versus 3.88 standard, P = .01). Consumption of all meals was acceptable. No differences occurred in the frequency of high or low blood sugars between standard and lower GI days. CONCLUSIONS AND IMPLICATIONS Higher quality carbohydrates may be provided to youth in institutional settings while maintaining sufficient levels of acceptability; specific findings are instructive for designing efforts to increase their consumption.

Abstract
OBJECTIVES To determine if the lunchtime food provided to schoolchildren adheres to nutritional standards and to examine the influence of children's food choice on nutrient intake at lunchtime. SUBJECTS/SETTING Seventy-four children aged 11-12 years were recruited from three secondary schools. The school populations spanned a spectrum of socio-economic deprivation. Lunchtime food and nutrient intake was assessed over a 5 day period. DESIGN Cross-sectional study of menu composition and children's food choice in relation to nutrient intake. METHODS Dietary recording was by an indirect weighing method of menu composition and nutrient intake over a 5 day period. Statistical analysis was carried out using general linear modelling techniques including: t-test, one-way ANOVA and ANCOVA. RESULTS One school met the standards on food group provision. Intakes of total fat, saturated fatty acids and monounsaturated fatty acids were greater in boys. Intake of folate was greater in girls. There were between-school differences (independent of gender) for intake of fatty acids, starch, calcium and folate, with socio-economic deprivation associated with a lesser nutrient intake. Children could have chosen meals higher in calcium, iron, folate and zinc and lower in starch and fat, from the extensive cafeteria menu of between 26 and 42 food. For some nutrients, providing 'healthier' food influences intake of those nutrients whilst for other nutrients, children's food choice predominates. The majority of children did not meet the recommended targets for lunchtime nutrient intake, especially for micronutrients. CONCLUSIONS Food provision in two out of three schools did not meet government guidelines and socio-economic deprivation was associated with worse food provision. Children from deprived areas were more likely to choose those foods of limited nutritional value than those from more privileged backgrounds. The statutory nutritional standards on their own, without a pricing policy to encourage healthier food choice or restrictions in food choice towards less healthy food are unlikely to catalyse the dietary changes that are so needed to ensure improved nutrient intakes amongst schoolchildren in England.

Abstract
BACKGROUND/AIMS The Pro Children Project was designed to assess fruit and vegetable consumption in European schoolchildren and their parents, as well as determinants of the children's consumption patterns. A second objective was to develop and test strategies, applicable across Europe, for promoting consumption of fruits and vegetables among schoolchildren and their parents. In this paper, the rationale, theoretical background, overall design and implementation of the project is presented. METHODS Surveys of national, representative samples of 11-year-old schoolchildren and their parents were conducted in 9 countries, i.e. in Austria, Belgium, Denmark, Iceland, the Netherlands, Norway, Portugal, Spain and Sweden. Comprehensive school-based educational programmes have been developed and tested in three settings, i.e. in Spain, the Netherlands and in Norway. A precoded 24-hour recall form combined with a set of food frequency questions assessing regular intake were used to assess fruit and vegetable consumption. Determinants were assessed employing a comprehensive theoretical framework including personal, social and environmental factors related to fruit and vegetable consumption. The intervention programmes have been tested employing a group-randomized trial design where schools have been randomly allocated to an intervention arm and a delayed intervention arm. Surveys among all participating children and their parents were conducted prior to the initiation of the intervention, immediately after the end of the intervention and at the end of the subsequent school year. CONCLUSION The project is expected to provide new information of great importance for improving our understanding of consumption patterns of fruits and vegetables and for guiding future efforts to promote increased consumption patterns across Europe.

Abstract
BACKGROUND This paper reviews the available literature on the school food environment with a focus on identifying effective strategies to promote vegetable and fruit (VF) consumption among youth in school settings. METHODS Studies were identified through a search of electronic databases as well as references cited within published articles. Seven studies were identified that evaluated changes in VF intake and included a control group. Four additional school-based interventions were reviewed that focused on changes in VF intake as part of a multibehavior intervention. RESULTS Multicomponent school interventions have been effective in increasing F intake, with reported increases ranging from 0.2 to 0.6 servings per day. Impact on V intake has been less effective, with increases ranging from 0 to 0.3 servings per day. Total VF increases ranged from 0 to 0.6 servings per day. Results of environmental-only, school-based interventions have shown positive effects on students' choice of targeted foods. CONCLUSIONS Environmental change interventions in schools show potential for positively affecting VF consumption among youth.
