Development and application of a 2-step methodology to select a reference society providing Dietary Reference Values for national implementation.

OBJECTIVE: To describe and discuss a 2-step methodology developed to select a reference society that provides Dietary Reference Values (DRV) for national implementation and to illustrate its application in Switzerland with one macronutrient and one micronutrient. DESIGN: During Step 1, we searched and compared DRV and methodologies used to define DRV from eight European societies for seven selected nutrients. We repeated this procedure during Step 2 for DRV from two preselected societies for forty-four nutrients. SETTING: The 2-step methodology applied here for Switzerland may be used in other countries. PARTICIPANTS: The research team commissioned six external experts from three linguistic regions of Switzerland, who provided their opinions through two online surveys, individual interviews and a focus group. RESULTS: After Step 1, we excluded five societies because of old publication dates, irrelevant publication languages for Switzerland, difficulty in accessing documents, or because their DRV were mainly based on another society. After Step 2, the two societies were qualified based on the analysis of the values and methodologies used. The need for free and easily accessible scientific background information favoured the European Food Safety Authority (EFSA). We chose alternative societies for nine nutrients for the overall population or subgroups and for the elderly. CONCLUSIONS: To manage heterogeneous and complex data from several societies, adopting a 2-step methodology including fewer nutrients and more societies during Step 1, and fewer societies but all nutrients in Step 2, was very helpful. With some exceptions, we selected EFSA as the main society to provide DRV for Switzerland.

A randomized controlled trial to evaluate the acceptability and effectiveness of two eating disorders prevention interventions: the HEIDI BP-HW project.

BACKGROUND: Eating disorders (ED) are common in Switzerland, as in other Western countries, with a prevalence of any ED of 3.5%. However, no specific prevention intervention has been evaluated in the French-speaking part of the country. In this study, we assessed the acceptability and effectiveness of two well-validated eating disorders prevention interventions: the Body Project intervention (BP), based on cognitive dissonance techniques, and the Healthy Weight intervention (HW), based on the implementation of a healthy lifestyle. METHODS: Forty female students, aged 18-28, with body dissatisfaction, were randomized into three arms: a BP group, an HW group, and a waiting-list control group (WLCG). The primary outcome measure was body dissatisfaction. Secondary outcomes were thin-ideal internalization, dietary restraint, negative affect, and ED psychopathology. Thirty-three participants completed the assessments before and after the one-month interventions or waiting period. A follow-up measurement was conducted one month after the interventions to assess the stability of the results. RESULTS: Both interventions, delivered via a virtual web platform, were considered acceptable. The reduction in body dissatisfaction was greater in the BP group (r = 0.7; p < 0.01) or the HW group (r = 0.6; p < 0.01) than in the WLCG, with large effect sizes. Dietary restraint and shape concern were also significantly reduced in the BP group (r = 0.6 and r = 0.7, respectively; p < 0.01) and HW group (r = 0.5 and r = 0.5, respectively; p < 0.05) compared to the WLCG, with moderate to large effect sizes. The results obtained in each intervention group were stable at the one-month follow-up. CONCLUSIONS: This study showed encouraging results in young women with body dissatisfaction, arguing in favor of the French adaptations of the BP and HW interventions. However, the feasibility of recruitment was difficult, partly due to the pandemic situation at the time of the study, and should be further considered to improve dissemination.

Associations Between Body Weight Dissatisfaction and Diet Quality in Women With a Body Mass Index in the Healthy Weight Category: Results From the 2014-2015 Swiss National Nutrition Survey.

BACKGROUND: Few studies have examined whether diet quality is lower in women with body weight dissatisfaction compared with women without body weight dissatisfaction. OBJECTIVES: (1) Examine the association between body weight dissatisfaction and diet quality among women (18-65 years old) in the healthy weight body mass index (BMI) category, and (2) explore dietary and behavioral patterns among women with body weight dissatisfaction. DESIGN: Data were extracted from the cross-sectional 2014-2015 Swiss National Nutrition Survey. PARTICIPANTS/SETTING: Population-based sample of 507 women with BMI ≥ 18.5 and < 25. OUTCOME MEASURES: Dietary intakes assessed by registered dietitians using 2 nonconsecutive computer-assisted multi-pass 24-hour dietary recalls. Diet quality was measured with a slightly modified version of the Healthy Eating Index (HEI)-2020. STATISTICAL ANALYSES PERFORMED: Multiple linear regressions were performed to test the association between body weight dissatisfaction and total HEI-2020 score. Hierarchical cluster analysis was used to identify subgroups of women with body weight dissatisfaction. RESULTS: Body weight dissatisfaction was not found to be associated with diet quality (ß = -1.73 [-4.18; 0.71], P = .16). However, women who were dissatisfied with their body weight had lower scores for the HEI-2020 total fruits (P = .050) and whole grains (P = .014) components than women who were satisfied with their body weight. Four profiles with different dietary patterns were identified among women with body weight dissatisfaction: "Unhealthy diet with dairy," "Protein and fat," "Vegetables without protein," and "Healthier diet without dairy." CONCLUSIONS: Among women with a BMI in the healthy weight category, overall diet quality was not observed to differ between those with or without body weight dissatisfaction. More research is needed to explore the different profiles of dietary intake in women with body weight dissatisfaction.

What Is the Nutritional Quality of Pre-Packed Foods Marketed to Children in Food Stores? A Survey in Switzerland.

Food marketing targeting children influences their choices and dietary habits, and mainly promotes food high in fat, sugar, and salt as well as ultra-processed food. The aim of this study was to assess the nutritional quality of food and beverages marketed to children over the age of 3 and available on the Swiss market. Products with at least one marketing technique targeting children on the packaging were selected from five food store chains. Three criteria to assess nutritional quality were used: (1) nutritional composition (using the Nutri-Score), (2) degree of processing (NOVA classification), and (3) compliance with the World Health Organization (WHO) Nutrient Profile Model (NPM). A total of 735 products were found and analyzed. The most common marketing techniques used were childish names/fonts (46.9%), special characters (39.6%), and children's drawings (31.3%). Most products had a Nutri-Score of D or E (58.0%) and were ultra-processed (91.8%). Only 10.2% of products displayed the Nutri-Score. The least processed products generally had a better Nutri-Score (p < 0.001). Most products (92.8%) did not meet the criteria of the WHO NPM. Products that met the WHO NPM criteria, organic products, and products with a nutritional claim generally had a better Nutri-Score and were less processed (ps < 0.05). Pre-packaged foods and beverages marketed to children in the Swiss market were mostly of poor nutritional quality. Public health measures should be adopted to improve the nutritional quality of foods marketed to children in Switzerland and restrict the marketing of unhealthy foods to children.

Translating and Testing a Digital Game Promoting Vegetable Consumption in Young Children: Usability Study.

BACKGROUND: Promoting healthy eating in children is key to preventing chronic diseases, and vegetable consumption is notably lower than recommended in this population. Among the interventions tested, gamification has shown promise in promoting familiarization, increasing knowledge, and potentially increasing vegetable intake. OBJECTIVE: This pilot study aimed first to translate the digital game "Veggies4myHeart" into French and to assess its influence on young children's preferences and willingness to taste vegetables when combined with repeated tasting and education. We also aimed to investigate the acceptability and applicability of the game in 2 classrooms. METHODS: During 5 consecutive weekly sessions, children from 2 elementary classes played the digital game consisting of 5 mini games on different vegetables (lettuce, carrot, red cabbage, cucumber, and tomato) in pairs for 10-15 minutes. In addition, they discussed one of the vegetables and tasted the 5 vegetables in each session. Pretest and posttest food preferences and willingness to taste the vegetables were compared. Teachers participated in a semistructured interview. RESULTS: A total of 45 children aged 5 to 6 years tested the French version of the digital game. The children's declared food preferences were already high for carrot, cucumber, and tomato, with scores higher than 4 out of a maximum of 5. The scores did not change significantly after the intervention, except for red cabbage (pretest: mean 2.52, SD 1.49; posttest: mean 3.29, SD 1.67; P=.006) and a composite score (pretest: mean 3.76, SD 1.06; posttest: mean 4.05, SD 1.03; P=.001). Before the intervention, 18 (44%), 30 (73%), 16 (39%), 29 (71%), and 26 (63%) children out of 41 were willing to taste lettuce, carrot, red cabbage, cucumber, and tomato, respectively. After the intervention, no significant statistical differences were observed, with 23 (51%), 36 (80%), 24 (53%), 33 (73%), and 29 (64%) children out of 45 willing to taste lettuce, carrot, red cabbage, cucumber, and tomato, respectively. Teachers supported this tool combined with repeated tasting and education and highlighted facilitators and barriers that should be anticipated to improve implementation in schools. CONCLUSIONS: In this study, we translated an existing digital game applicable and acceptable to both children and teachers. A larger study is warranted to confirm the effectiveness of interventions using the digital game to promote vegetable preference, willingness to taste, and intake.

The Consumption of Insects in Switzerland: University-Based Perspectives of Entomophagy.

Although insects have long been part of the human diet in many countries, they are poorly received and accepted in European and North American countries. Therefore, this cross-sectional observational study, based on a structured questionnaire, aimed to evaluate the level of acceptability of entomophagy among young adults in a Swiss university context. The variable "acceptability of consuming insects" (ACI) was calculated according to the perception of entomophagy of each participant. The ACI was related to various socio-demographic and behavioral aspects. A total of 290 responses were validated and analyzed. The mean ACI score was 3.7 out of 6.0 (SD 1.1). Most participants responded that the most likely reason for eating insect foods was curiosity. The most common reason for not eating such foods was disgust. None of the socio-demographic variables showed a significant association with ACI. Generally, participants in this study showed a potential interest in entomophagy-on a theoretical level, as measured here by the ACI. In practice, however, there are still barriers, including disgust, which contribute to the low consumption of these foods, at least in Switzerland.

Description of Ultra-Processed Food Intake in a Swiss Population-Based Sample of Adults Aged 18 to 75 Years.

Ultra-processed foods (UPFs) are associated with lower diet quality and several non-communicable diseases. Their consumption varies between countries/regions of the world. We aimed to describe the consumption of UPFs in adults aged 18−75 years living in Switzerland. We analysed data from the national food consumption survey conducted among 2085 participants aged 18 to 75 years. Foods and beverages resulting from two 24-h recalls were classified as UPFs or non-UPFs according to the NOVA classification, categorized into 18 food groups, and linked to the Swiss Food Composition Database. Overall, the median energy intake [P25−P75] from UPFs was 587 kcal/day [364−885] or 28.7% [19.9−38.9] of the total energy intake (TEI). The median intake of UPFs relative to TEI was higher among young participants (<30 years, p = 0.001) and those living in the German-speaking part of Switzerland (p = 0.002). The food groups providing the most ultra-processed calories were confectionary, cakes & biscuits (39.5% of total UPF kcal); meat, fish & eggs (14.9%); cereal products, legumes & potatoes (12.5%), and juices & soft drinks (8.0%). UPFs provided a large proportion of sugars (39.3% of total sugar intake), saturated fatty acids (32.8%), and total fats (31.8%) while providing less than 20% of dietary fibre. Consumption of UPFs accounted for nearly a third of the total calories consumed in Switzerland. Public health strategies to reduce UPF consumption should target sugary foods/beverages and processed meat.

A study protocol for a preliminary randomised controlled trial assessing the acceptability and effectiveness of two eating disorders prevention interventions in Switzerland: The HEIDI BP-HW project.

Because of the serious consequences of eating disorders on young women's lives and because of the lack of specialised care facilities, assessing and implementing evidence-based prevention interventions is necessary. Switzerland, like other Western countries, has high prevalence rates of eating disorders. However, no prevention interventions have been evaluated in this country so far. This paper presents the protocol of a preliminary study with the aim to evaluate the acceptability and effectiveness of two interventions, the Body Project (BP) and the Healthy Weight Program (HW), for female students from French-speaking Switzerland. These two interventions were chosen because they have been widely evaluated and they proved to be effective in various countries. They take place in groups and include four weekly sessions over one month. Because of the pandemic situation, the group sessions will take place online on an collaborative platform. The design is a three-arm randomised controlled study. Ninety female students aged 18-25 and presenting with at least moderate body dissatisfaction will be randomised into three groups: (1) one-month BP intervention, (2) one-month HW intervention, and (3) one-month waiting-list control group followed by the BP intervention. Assessments of body dissatisfaction, thin-ideal internalisation, dietary restraint, negative affect, and eating disorder psychopathology will be conducted before and after the interventions or waiting list and after a one-month follow-up. ANCOVA and ANOVA with repeated measures will be used to assess group differences and follow-up stability. Acceptability will be assessed with a questionnaire on participants' satisfaction with the interventions, group discussion at the end of the intervention, and with participants' rate of attendance to the group sessions. The study results will provide additional data on these two eating disorders prevention interventions and will suggest ways for their dissemination and further evaluation in Switzerland.

Healthy Snacks in School: How Do Regulations Work? A Mixed-Design Study.

BACKGROUND: School is an important setting to promote healthy eating habits for children. We compared the effects of 4 conditions on the nutritional quality of snacks brought to school. We also investigated teachers' opinions regarding the process, barriers, and facilitators in regulation implementation. METHODS: We compared the nutritional quality of morning snacks based on 1958 photographs from schools divided into 4 conditions: regulation based on a list of permitted foods and beverages; regulation banning sweets, chips, and sugary drinks; information without regulation; or no intervention. Based on 5 focus groups (N = 18 participants), we investigated factors influencing regulation implementation. RESULTS: In schools with a list of permitted foods and beverages, 76% of the children had a healthy snack, compared to 52% to 54% in the 3 other conditions (p < .01). They also brought less sweet foods compared to those in the other conditions (41% vs. 68% to 71%, p < .01). In focus groups, most teachers supported regulation but also expressed ambivalence about their legitimacy. CONCLUSIONS: In this study, a regulation based on a list of permitted foods and beverages showed the best results. All actors should be involved in a progressive implementation process to increase acceptance of such regulation.

Impact of Measures Aiming to Reduce Sugars Intake in the General Population and Their Implementation in Europe: A Scoping Review.

Objectives: Implementing public health measures is necessary to decrease sugars intake, which is associated with increased risk of noncommunicable diseases. Our scoping review aimed to identify the types of measures implemented and evaluated to decrease sugars intake in the population and to assess their impact. Methods: Following a review of systematic reviews (SRs) published in 2018, we systematically searched new SR (May 2017-October 2020) in electronic databases. We also searched the measures implemented in Europe in the NOURISHING database. Two researchers selected the reviews, extracted and analysed the data. Results: We included 15 SRs assessing economic tools (n = 5), product reformulation and labels/claims (n = 5), and educational/environmental interventions (n = 7). Economic tools, product reformulation and environmental measures were effective to reduce sugar intake or weight outcomes, while labels, education and interventions combining educational and environmental measures found mixed effects. The most frequently implemented measures in Europe were public awareness, nutritional education, and labels. Conclusion: Among measures to reduce sugar intake in the population, economic tools, product reformulation, and environmental interventions were the most effective, but not the more frequently implemented in Europe.

Consumption of Ultraprocessed Foods in a Sample of Adolescents With Obesity and Its Association With the Food Educational Style of Their Parent: Observational Study.

BACKGROUND: Both parental education and the food environment influence dietary intake and may therefore contribute to childhood obesity. OBJECTIVE: We aimed to assess the consumption of ultraprocessed foods (UPFs) in a convenience sample of adolescents with obesity and to determine its association with the food educational style of their parent. METHODS: This observational study included 24 participants, 12 adolescents (8 boys and 4 girls) aged from 12 to 14 years and their 12 parents, who were followed in a specialized pediatric obesity clinic in the French-speaking part of Switzerland. The adolescents were asked to take a photograph with a smartphone application of all meals and beverages consumed in their daily routine over 14 consecutive days. They evaluated their parent's food educational style using the Kids' Child Feeding Questionnaire. The parent who was present at the study visits also completed the Feeding Style Questionnaire. A dietitian analyzed the pictures to extract food group portions and to identify UPFs using the NOVA classification. A nonparametric statistical test was used to investigate associations between UPF intake and food educational style. RESULTS: Overall, the adolescents had unbalanced dietary habits compared to national recommendations. They consumed an insufficient quantity of vegetables, fruits, dairy products, and starchy foods and an excessive amount of meat portions and sugary and fatty products compared to the current Swiss recommendations. Their consumption of UPFs accounted for 20% of their food intake. All adolescents defined their parent as being restrictive in terms of diet, with a mean parental restriction score of 3.3±SD 0.4 (norm median=2.1). No parent reported a permissive food educational style. A higher intake of UPFs was associated with a lower parental restriction score (P=.04). CONCLUSIONS: Despite being followed in a specialized pediatric obesity clinic, this small group of adolescents had an unbalanced diet, which included 20% UPFs. The intake of UPFs was lower in participants whose parent was more restrictive, suggesting the importance of parents as role models and to provide adequate food at home.

Energy, Nutrient and Food Intakes of Male Shift Workers Vary According to the Schedule Type but Not the Number of Nights Worked.

Shift work is associated with increased risk of chronic diseases due to circadian rhythm disruptions and behavioral changes such as in eating habits. Impact of type of shifts and number of night shifts on energy, nutrient and food intake is as yet unknown. Our goal was to analyze shift workers' dietary intake, eating behavior and eating structure, with respect to frequency of nights worked in a given week and seven schedule types. Eating habits and dietary intakes of 65 male shift workers were analyzed in three steps based on 365 24-h food records: (1) according to the number of nights, (2) in a pooled analysis according to schedule type, and (3) in search of an interaction of the schedule and the timing of intake. Mean nutrient and food group intake during the study period did not depend on the number of nights worked. Amount and distribution of energy intake as well as quality of food, in terms of nutrient and food groups, differed depending on the type of schedule, split night shifts and recovery day (day after night shift) being the most impacted. Shift workers' qualitative and quantitative dietary intakes varied between different schedules, indicating the need for tailored preventive interventions.

Eating Habits of Professional Firefighters: Comparison With National Guidelines and Impact Healthy Eating Promotion Program.

OBJECTIVE: Firefighters' eating habits may be an additional risk factor for metabolic diseases. We assessed eating habits of firefighters, compared them with national guidelines, and evaluated the impact of a prevention program. METHODS: Twenty-eight professional firefighters from a Swiss airport benefited from a healthy-eating program. Food intake, eating behavior, and anthropometric data were collected at baseline and 1-year follow-up using an electronic food record, questionnaires, and bio-impedance. RESULTS: Participants had unbalanced diets with low-quality food choices associated with low intakes of fibers and micronutrients compared with national guidelines. Intervention did not impact eating habits or anthropometrics data at the group level, but changes were measured in sub-groups. Main reported barriers for healthy eating were lack of motivation, prioritization, or time. CONCLUSIONS: Intensive and culturally tailored prevention interventions targeting nutritional behaviors are needed at the individual, group, and organizational levels.

Effectiveness of individual and group programmes to treat obesity and reduce cardiovascular disease risk factors in pre-pubertal children.

Childhood obesity results in premature atherosclerosis and requires early intervention. Compare the effectiveness of 6-month lifestyle interventions (with choice of either individual or group therapy) with standard care on body mass index (BMI) z-score and cardiovascular disease (CVD) risks factors in children with obesity. This 6-month randomized controlled trial with a 6-month follow-up included 74 pre-pubertal children with obesity (7.5-11.9 years) assigned randomly (2:1) to intervention or control. Families in the intervention arm choose between an individually delivered treatment (3 hours paediatrician + 4 hours dietician) or group treatment (35 hours with a multidisciplinary team). Children participated also to a weekly physical activity programme. We measured BMI, BMI z-score; waist circumference (WC); total and abdominal fat; blood pressure; common carotid artery intima-media thickness and incremental elastic modulus (Einc); endothelium-dependent and independent dilation (nitroglycerin-mediated dilation [NTGMD]) of the brachial artery; fasting plasma glucose, insulin, lipids; and high-sensitivity C-reactive protein (hs-CRP). Compared to controls, at 6 months, abdominal fat and hs-CRP were reduced in both interventions. The group intervention was also effective in reducing BMI (-0.55 kg/m2 ; 95% confidence interval -1.16 to 0.06) and BMI z-score (-0.08; -0.15 to 0.00) at 6 months and BMI, BMI z-score, WC, NTGMD, total and abdominal fat at 12 months. Abdominal fat and low-grade inflammation were significantly decreased in both interventions. High-intensity group treatment improved early signs of atherosclerosis in children with obesity. These findings are important for the promotion of cardiometabolic health in this population.

Development and Evaluation of e-CA, an Electronic Mobile-Based Food Record.

Measures that capture diet as validly and reliably as possible are cornerstones of nutritional research, and mobile-based devices offer new opportunities to improve and simplify data collection. The balance between precision and acceptability of these data collection tools remains debated, and rigorous validations are warranted. Our objective was to develop and evaluate an electronic mobile-based food record for a research setting. We developed e-CA, which includes almost 900 foods and beverages classified in 14 categories and 60 subcategories. e-CA was evaluated using three different methods: (1) usability and acceptability through a logbook and qualitative interviews; (2) dietary intake accuracy through comparison with 2 unannounced 24-h phone recalls on overlapping days; and (3) reliability and process comparison with a paper-based food record in a laboratory setting with a randomized design. e-CA proved to be intuitive and practical and was perceived as modern, trendy, and fun. Comparisons of e-CA with 24-h telephone recalls or paper-based food records in a laboratory setting with two small convenient samples showed good agreement but highlighted the well-known difficulty of estimating portion sizes and a necessary learning time to use the app. e-CA is a functional tool that has the potential to facilitate food intake measurement for research by increasing the pleasure of using the food record tool and reducing the perceived burden for the participants. It also decreases the workload, costs and the risk of transcription errors for researchers.

Sugar-Sweetened Beverages and Obesity Risk in Children and Adolescents: A Systematic Analysis on How Methodological Quality May Influence Conclusions.

BACKGROUND: In the context of a worldwide high prevalence of childhood obesity, the role of sugar-sweetened beverage (SSB) consumption as a cause of excess weight gain remains controversial. Conflicting results may be due to methodological issues in original studies and in reviews. OBJECTIVE: The aim of this review was to systematically analyze the methodology of studies investigating the influence of SSB consumption on risk of obesity and obesity among children and adolescents, and the studies' ability to answer this research question. METHODS: A systematic review of cohort and experimental studies published until December 2013 in peer-reviewed journals was performed on Medline, CINAHL, Web of Knowledge, and ClinicalTrials.gov. Studies investigating the influence of SSB consumption on risk of obesity and obesity among children and adolescents were included, and methodological quality to answer this question was assessed independently by two investigators using the Academy of Nutrition and Dietetics Quality Criteria Checklist. RESULTS: Among the 32 identified studies, nine had positive quality ratings and 23 studies had at least one major methodological issue. Main methodological issues included SSB definition and inadequate measurement of exposure. Studies with positive quality ratings found an association between SSB consumption and risk of obesity or obesity (n=5) (ie, when SSB consumption increased so did obesity) or mixed results (n=4). Studies with a neutral quality rating found a positive association (n=7), mixed results (n=9), or no association (n=7). CONCLUSIONS: The present review shows that the majority of studies with strong methodology indicated a positive association between SSB consumption and risk of obesity or obesity, especially among overweight children. In addition, study findings highlight the need for the careful and precise measurement of the consumption of SSBs and of important confounders.

Sugar-Sweetened Beverages and Obesity among Children and Adolescents: A Review of Systematic Literature Reviews.

BACKGROUND: The prevalence of overweight and obesity among children and adolescents has increased worldwide and has reached alarming proportions. Currently, sugar-sweetened beverages (SSBs) are the primary source of added sugar in the diet of children and adolescents. Contradictive findings from studies and reviews have fueled an endless debate on the role of SSBs in the development of childhood obesity. OBJECTIVES: The primary aim of the present review of reviews was to assess how review- and study-level methodological factors explain conflicting results across reviews and meta-analyses by providing an up-to-date synthesis of recent evidence regarding the association between SSB consumption and weight gain, overweight, and obesity in a population of 6-month-old to 19-year-old children and adolescents. The secondary aim was to assess the quality of included reviews using the Assessment of Multiple SysTemAtic Reviews (AMSTAR) measurement tool. METHODS: Systematic literature reviews and meta-analyses were included. The literature search was performed through the platforms Pubmed/Medline, Cinahl, and Web of Knowledge. RESULTS: Thirteen reviews and meta-analyses were included. Nine reviews concluded that there was a direct association between SSBs and obesity in children and adolescents and four others did not. The quality of the included reviews was low to moderate, and the two reviews with the highest quality scores showed discrepant results. CONCLUSIONS: The majority of reviews concluded that there was a direct association between SSB consumption and weight gain, overweight, and obesity in children and adolescents. However, recent evidence from well-conducted meta-analyses shows discrepant results regarding the association between SSB and weight gain, overweight, and obesity among children and adolescents. Improving methodological quality of studies and reviews as well as ensuring responsible conduct of research and scientific integrity is essential for the provision of objective results.

'Croque&bouge': A feasible and acceptable programme for obesity prevention in preschoolers at risk and their parents.

OBJECTIVES: To conceptualize and pilot test a programme of three workshops aiming to prevent the development of overweight in susceptible preschool children. METHODS: Three workshops were conducted, targeting both parents and children. The curriculum for parents included discussions on feeding responsibilities, healthy eating, taste development, neophobia and physical activity recommendations. Children participated in various play activities with fruits and vegetables and read stories about hunger and satiety feelings. Recruitment was organized through paediatricians and child-care centres. Evaluation of the programme focused on feasibility, adequacy for children's age, parents' perception of impact and, for children, change of the ability to recognize and willingness to taste fruits and vegetables. RESULTS: A total of 21 children and one of their parents participated in the programme. The programme was found to be feasible and adequate for the targeted community. Parents reported perceiving a positive impact of the intervention; however, this finding was not statistically significant. The major difficulty was identifying and recruiting families and engaging the parents in a discussion about weight. CONCLUSIONS: This short programme aiming to improve parents' ability to offer healthy environment and promote healthy eating behaviour was feasible and acceptable for families with young children. When developing and implementing such programmes, close collaboration with paediatricians and other health providers should be sought in order to identify and reach children at risk of obesity and their family.

Obesity prevention opinions of school stakeholders: a qualitative study.

BACKGROUND: In general, schools are an important setting to implement current recommendations for obesity prevention in children because the vast majority of children attend school. This study investigated the opinions of different school stakeholders on the feasibility and acceptability of current obesity prevention strategies that could be implemented in Swiss schools. METHODS: Research methods were comprised of a qualitative study which included school directors, physical education teachers, catering staff, school nurses and health educators, parents of young adolescents, and young adolescents interviewed (N = 40) categorized into 6 focus groups. Open-ended questions were used to determine the participants' opinion regarding current obesity prevention recommendations, and healthy eating and physical activity promotion strategies. RESULTS: All participants approved the implementation of nutritional standards for food and drinks sold in schools, but thought that increasing the attractiveness of healthy options was the best strategy to improve eating habits. Enjoying participation in physical activity classes or after-school activities was stressed. Participants suggested offering classes for all students with poor physical condition, independent of weight status. Stakeholders called for governmental support and global coordination of interventions balanced with providing schools with enough autonomy to adapt programs relevant to their individual circumstances. They recommended integrating all school stakeholders in obesity prevention initiatives, with special attention to students and local authorities. CONCLUSIONS: Participants agreed that schools are a crucial setting to implement childhood obesity prevention strategies. They called on school stakeholders to join efforts aiming to encourage healthy behaviors and to support and reinforce parents' efforts by spreading consistent and coherent health messages.
