Willingness for more vegetarian meals in school canteens: Associations with family characteristics and parents' food choice motives in a French community.

The school meal system could contribute to the transition towards more sustainable food system by promoting plant-based meals. Knowing whether parents want more vegetarian school meals for their children is a prerequisite for a successful implementation. The present study aimed to estimate the proportion of parents who would opt for more vegetarian school meals for their children and to study associations of willingness with family characteristics and food choice motives. An online survey was sent to parents whose children are registered for school canteen in Dijon (France). We collected child-level information, data on family sociodemographic characteristics, and data on dietary habits and food choice motives of the family. We examined family characteristics associated with the willingness to increase the frequency of vegetarian school meals from one meal per week to two or daily. Generalized linear models were performed. In total, 49% of parents were willing to opt for a second weekly vegetarian meal and 26% for a daily vegetarian meal for their children (n = 1261). Parents willing to opt for more vegetarian meal were more likely to have higher education, be flexitarian or vegetarian and to currently opt for pork-free meals for their children, and their children attended the school canteen less frequently. Environmental motives were positively associated with the willing to opt for a second weekly vegetarian meal; familiarity and sensory appeal motives were negatively associated. Health and animal welfare motives were positively associated with the willing to opt for a daily vegetarian meal and sensory appeal was negatively associated. Increasing the frequency of vegetarian school meals would satisfy a demand expressed by parents but must be accompanied by interventions enhancing pleasure of eating vegetarian meals.

Children's liking for vegetarian and non-vegetarian school meals at the scale of a French city.

In Western countries, a behavioural shift towards more plant-based diets is helpful in protecting population and planet health. School canteens are an important public policy target to achieve this transition. Increasing the frequency of vegetarian meals in school canteens has been proposed as a solution to decrease greenhouse gas emissions while maintaining a good nutritional quality. However, vegetarian meals acceptance by children is key to limit unintended consequences such as increased food waste or increased nutritional inequalities. We aimed to examine children's liking for vegetarian and non-vegetarian main dishes at school canteens; and whether it varied across socioeconomic level. Connected scoring devices displaying a five-point smiley scale were installed in all the 38 primary school canteens of a French city, located in socially diverse neighbourhoods. Every day after their school lunch, children were asked to rate the main dish they had just eaten. During one school year, from September 2021 to June 2022, we collected 208,985 votes for 125 main dishes, including 32 vegetarian (i.e., no meat or fish) and 93 non-vegetarian dishes, for an average of 1672 (SD 440) votes per day across the 38 school canteens. We showed no difference in children's liking for vegetarian and non-vegetarian dishes. Additionally, the socioeconomic level of the schools was found to interact negatively with children's liking for vegetarian main dishes whereby vegetarian main dishes tended to be more liked in schools of lower socioeconomic level. In this French city, children's acceptance would not be a barrier to increase the frequency of vegetarian school meals and would not increase social dietary inequalities.

Behavioural determinants of healthy and environmentally friendly diets in French university students.

Although encouraging the shift toward sustainable diets in young adults is a major challenge to preserve population and planet health, the precursors of sustainable diets in this population remain unknown. This study aimed to identify the behavioural determinants of healthier and more environmentally friendly diets among university students. A sample of 582 French university students reported their food consumption using an online 125-item food frequency questionnaire. The nutritional quality (adherence to French recommendations, sPNNS-GS2) and the greenhouse gas emissions (GHGE) of students' diets were calculated for an isocaloric diet. Behavioural determinants were measured based on a literature review and classified into the Capability, Opportunity, Motivation Behaviour (COM-B) framework. Linear models, adjusted for socioeconomic characteristics, were run to identify the most prominent behavioural predictors of nutritional quality and GHGE of students' diets. Higher cooking skills (ß = 0.38, p = 0.01) and health motives (ß = 0.91, p < 0.001) were associated with higher nutritional quality. Greater environmental knowledge was linked to lower GHGE (ß = -0.07, p = 0.002), while health and weight control motives were associated with higher GHGE (ß = 0.26, p = 0.02 and ß = 0.39, p < 0.001). Enhancing cooking skills and environmental knowledge could enable healthy and environmentally friendly diets, but health-based motives can act as a lever and as a barrier.

Socioeconomic position and the influence of food portion size on daily energy intake in adult females: two randomized controlled trials.

BACKGROUND: Reducing portion sizes of commercially available foods could be an effective public health strategy to reduce population energy intake, but recent research suggests that the effect portion size has on energy intake may differ based on socioeconomic position (SEP). OBJECTIVE: We tested whether the effect of reducing food portion sizes on daily energy intake differed based on SEP. METHODS: Participants were served either smaller or larger portions of food at lunch and evening meals (N = 50; Study 1) and breakfast, lunch and evening meals (N = 46; Study 2) in the laboratory on two separate days, in repeated-measures designs. The primary outcome was total daily energy intake (kcal). Participant recruitment was stratified by primary indicators of SEP; highest educational qualification (Study 1) and subjective social status (Study 2), and randomisation to the order portion sizes were served was stratified by SEP. Secondary indicators of SEP in both studies included household income, self-reported childhood financial hardship and a measure accounting for total years in education. RESULTS: In both studies, smaller (vs larger) meal portions led to a reduction in daily energy intake (ps < .02). Smaller portions resulted in a reduction of 235 kcal per day (95% CI: 134, 336) in Study 1 and 143 kcal per day (95% CI: 24, 263) in Study 2. There was no evidence in either study that effects of portion size on energy intake differed by SEP. Results were consistent when examining effects on portion-manipulated meal (as opposed to daily) energy intake. CONCLUSIONS: Reducing meal portion sizes could be an effective way to reduce overall daily energy intake and contrary to other suggestions it may be a socioeconomically equitable approach to improving diet. TRIAL REGISTRATION: These trials were registered at www. CLINICALTRIALS: gov as NCT05173376 and NCT05399836.

Traffic-light front-of-pack environmental labelling across food categories triggers more environmentally friendly food choices: a randomised controlled trial in virtual reality supermarket.

BACKGROUND: Food systems highly contribute to anthropogenic greenhouse gas emissions and shifting towards more environmentally friendly diets is urgently needed. Enabling consumers to compare the environmental impact of food products at point-of-purchase with front-of-pack labelling could be a promising strategy to trigger more environmentally friendly food choices. This strategy remained to be tested. METHODS: The effect of a new traffic-light front-of-pack environmental label on food choices was tested in a 2-arm randomised controlled trial in a virtual reality supermarket. Participants (n = 132) chose food products to compose two main meals for an everyday meal scenario and for an environmentally friendly meal scenario with or without the label. The environmental label (ranging from A: green/lowest impact, to E: red/highest impact) was based on the Environmental Footprint (EF) single score calculation across food categories. The effect of the label on the environmental impact of food choices in each scenario was tested using linear mixed models. RESULTS: In the everyday meal scenario, the environmental impact of meals was lower in the label condition than in the no label condition (-0.17 ± 0.07 mPt/kg, p = 0.012). This reduction was observed at no nutritional, financial nor hedonic cost. The effectiveness of the label can be attributed to a change in the food categories chosen: less meat-based and more vegetarian meals were chosen with the label. In the environmentally friendly meal scenario, we demonstrated that the label provided new information to the participants as they were able to further reduce the environmental impact of their food choices with the label (-0.19 ± 0.07 mPt/kg, p = 0.005). CONCLUSIONS: Implementing a front-of-pack environmental label on food products in real supermarkets could increase awareness of the environmental impact of food and contribute to drive more environmentally friendly food choices. TRIAL REGISTRATION: The study protocol was pre-registered prior to data collection at Clinicaltrials.gov (NCT04909372).

Socioeconomic position and the effect of energy labelling on consumer behaviour: a systematic review and meta-analysis.

BACKGROUND: There are well documented socioeconomic disparities in diet quality and obesity. Menu energy labelling is a public health policy designed to improve diet and reduce obesity. However, it is unclear whether the impact energy labelling has on consumer behaviour is socially equitable or differs based on socioeconomic position (SEP). METHODS: Systematic review and meta-analysis of experimental (between-subjects) and pre-post implementation field studies examining the impact of menu energy labelling on energy content of food and/or drink selections in higher vs. lower SEP groups. RESULTS: Seventeen studies were eligible for inclusion. Meta-analyses of 13 experimental studies that predominantly examined hypothetical food and drink choices showed that energy labelling tended to be associated with a small reduction in energy content of selections that did not differ based on participant SEP (X2(1) = 0.26, p = .610). Effect estimates for higher SEP SMD = 0.067 [95% CI: -0.092 to 0.226] and lower SEP SMD = 0.115 [95% CI: -0.006 to 0.237] were similar. A meta-analysis of 3 pre-post implementation studies of energy labelling in the real world showed that the effect energy labelling had on consumer behaviour did not significantly differ based on SEP (X2(1) = 0.22, p = .636). In higher SEP the effect was SMD = 0.032 [95% CI: -0.053 to 0.117] and in lower SEP the effect was SMD = -0.005 [95% CI: -0.051 to 0.041]. CONCLUSIONS: Overall there was no convincing evidence that the effect energy labelling has on consumer behaviour significantly differs based on SEP. Further research examining multiple indicators of SEP and quantifying the long-term effects of energy labelling on consumer behaviour in real-world settings is now required.

Is the effect of menu energy labelling on consumer behaviour equitable? A pooled analysis of twelve randomized control experiments.

Menu energy labelling has been implemented as a public health policy to promote healthier dietary choices and reduce obesity. However, it is unclear whether the influence energy labelling has on consumer behaviour differs based on individuals' demographics or characteristics and may therefore produce inequalities in diet. Data were analysed from 12 randomized control trials (N = 8508) evaluating the effect of food and drink energy labelling (vs. labelling absent) on total energy content of food and drink selections (predominantly hypothetical) in European and US adults. Analyses examined the moderating effects of participant age, sex, ethnicity/race, education, household income, body mass index, dieting status, food choice motives and current hunger on total energy content of selections. Energy labelling was associated with a small reduction (f2 = 0.004, -50 kcal, p < 0.001) in total energy selected compared to the absence of energy labelling. Participants who were female, younger, white, university educated, of a higher income status, dieting, motivated by health and weight control when making food choices, and less hungry, tended to select menu items of lower energy content. However, there was no evidence that the effect of energy labelling on the amount of energy selected was moderated by any of the participants' demographics or characteristics. Energy labelling was associated with a small reduction in energy content of food selections and this effect was similar across a range of participants' demographics and characteristics. These preliminary findings suggest that energy labelling policies may not widen existing inequalities in diet.

The role of health-based food choice motives in explaining the relationship between lower socioeconomic position and higher BMI in UK and US adults.

BACKGROUND/OBJECTIVES: Lower socioeconomic position (SEP) is associated with increased risk of higher BMI and developing obesity. No research to date has directly examined whether SEP differences in health-based food choice motives or executive function explain why lower SEP is associated with higher BMI. SUBJECTS/METHODS: We analysed observational data from large samples of UK (N = 4130) and US (N = 1898) adults which included measures of SEP (education level, household income and subjective social status) and self-reported BMI. Participants also completed validated self-report measures on the extent to which their day-to-day food choices were motivated by health and weight control, as well as completing computerized tasks measuring inhibitory control (Stroop task) and working memory (Digit span task). RESULTS: Across both UK and US adults, the relationship between indicators of lower SEP and higher BMI were consistently explained by participants from lower SEP backgrounds reporting being less motivated by health when making food choices, which accounted for 18-28% of the association between lower SEP and higher BMI. There was no evidence that measures of executive function explained associations between SEP and BMI or moderated relations between food choice motives and higher BMI. CONCLUSIONS: SEP differences in health-based food choice motives may play an important role in explaining why lower SEP is associated with an increased risk of higher BMI.

Increasing availability of lower energy meals vs. energy labelling in virtual full-service restaurants: two randomized controlled trials in participants of higher and lower socioeconomic position.

BACKGROUND: There are a range of interventions designed to promote healthier food choices in full-service restaurants. However, it is unclear how these interventions affect dietary choices in people of lower and higher socioeconomic position (SEP). METHODS: A total of 2091 US participants recruited online completed Study 1 (n = 1001) and Study 2 (n = 1090). Recruitment was stratified by participant highest education level, resulting in higher SEP and lower SEP groups. In a between-subjects design, participants made hypothetical food choices (main dish, plus optional sides and desserts) from six restaurants menus in the absence vs. presence of menu energy labelling and from menus with baseline (10%) vs. increased availability (50%) of lower energy main dishes. Data were collected and analysed in 2019. Two studies were conducted in order to examine replicability and generalisability of findings across different restaurant menu types. RESULTS: Across both studies, increasing the availability of lower energy main menu options decreased the average energy content of the ordered main dish (- 129 kcal, 95% CI [- 139; - 119]) and total energy ordered (- 117 kcal, 95% CI [- 138; - 95]) in both higher and lower SEP participants. Energy labelling significantly reduced the energy content of ordered main dishes in higher SEP participants (- 41 kcal, 95% CI [- 54; - 29]), but not lower SEP participants (- 5 kcal, 95% CI [- 22; 11]). However, energy labelling reduced total energy ordered (- 83 kcal, 95% CI [- 105; - 60]) irrespective of SEP. CONCLUSIONS: In two virtual experiments, increasing the availability of lower energy restaurant main menu options impacted on main menu dish choice and decreased total energy ordered irrespective of SEP. Energy labelling had a less pronounced effect on total energy ordered and had a larger impact on the energy content of main menu dish choice in higher as opposed to lower SEP participants.

Socioeconomic position, energy labelling and portion size selection: An online study comparing calorie and physical activity calorie equivalent (PACE) labelling in UK adults.

Limited research has examined the impact of energy labelling on portion size selection. It is also unclear whether physical activity calorie equivalent (PACE) is more effective than standard kilocalorie (kcal) energy labelling in promoting healthier dietary behaviour and whether effectiveness varies based on socioeconomic position (SEP). In the present online study, 1667 UK adults of lower and higher SEP made virtual portion size selections for 18 common main meal foods under one of four conditions: kcal labelling only, PACE labelling only, kcal and PACE labelling, no labelling. Contrary to predictions, participants in the kcal labelling condition (+55 kcal, p < 0.001) chose larger portion sizes compared to the no labelling condition, whereas the PACE labelling (-17 kcal, p = 0.065) and no labelling condition did not significantly differ. The presence of PACE information on labels was associated with selection of significantly smaller portions when compared to labels that only included kcal information. Effects of labels on portion size selection were not moderated by participant SEP in primary analyses. The present study of virtual portion size selections suggests that kcal labelling resulted in larger portion size selections than no labelling, but this counter-intuitive effect was attenuated when kcal and PACE labelling were combined. Further research examining the impact of PACE labelling on real-world food selection in participants of lower and higher SEP is now warranted.

Food choice motives and the nutritional quality of diet during the COVID-19 lockdown in France.

To limit the transmission of COVID-19, nationwide lockdown was imposed in France between March, 17th and May 10th, 2020. This disruption in individuals' daily routines likely altered food consumption habits. We examined how changes in food choice motives related to changes in nutritional quality during the lockdown compared to before. A convenience sample of 938 French adults completed online questionnaires on the Qualtrics platform at the end of April 2020. Participants were retrospectively asked about their food choice motives and food consumption during the month before and in the first month of the lockdown. The importance of nine food choice motives was assessed: health, convenience, sensory appeal, natural content, ethical concern, weight control, mood, familiarity, and price, scoring from 1 to 4. Food intakes were recorded using a food frequency questionnaire including 110 foods, 12 non-alcoholic beverages and 4 alcoholic beverages. Adherence to the French dietary recommendations before and during the lockdown was estimated using the simplified PNNS-GS2, scoring from -17 to 11.5. The nutritional quality of diet was lower during the lockdown compared to before (-0.32, SD 2.28, p < 0.001). Food choice motives significantly changed and an increase in the importance of weight control was associated with increased nutritional quality (ß = 0.89, p < 0.001, partial η2 = 0.032), whereas an increase in the importance of mood was associated with decreased nutritional quality (ß = -0.43, p = 0.021, partial η2 = 0.006). The lockdown period in France was related to a decrease in nutritional quality of diet on average, which could be partly explained by changes in food choice motives. The lockdown was indeed related to modification of food choice motives, notably with an increase of mood as a food choice motive for 48% of the participants, but also with an increase of health (26%), ethical concern (21%) and natural content (19%) suggesting a growing awareness of the importance of sustainable food choices in some participants.

Obesity, eating behavior and physical activity during COVID-19 lockdown: A study of UK adults.

Eating, physical activity and other weight-related lifestyle behaviors may have been impacted by the COVID-19 crisis and people with obesity may be disproportionately affected. We examined weight-related behaviors and weight management barriers among UK adults during the COVID-19 social lockdown. During April-May of the 2020 COVID-19 social lockdown, UK adults (N = 2002) completed an online survey including measures relating to physical activity, diet quality, overeating and how mental/physical health had been affected by lockdown. Participants also reported on perceived changes in weight-related behaviors and whether they had experienced barriers to weight management, compared to before the lockdown. A large number of participants reported negative changes in eating and physical activity behavior (e.g. 56% reported snacking more frequently) and experiencing barriers to weight management (e.g. problems with motivation and control around food) compared to before lockdown. These trends were particularly pronounced among participants with higher BMI. During lockdown, higher BMI was associated with lower levels of physical activity and diet quality, and a greater reported frequency of overeating. Reporting a decline in mental health because of the COVID-19 crisis was not associated with higher BMI, but was predictive of greater overeating and lower physical activity in lockdown. The COVID-19 crisis may have had a disproportionately large and negative influence on weight-related behaviors among adults with higher BMI.

The energy and nutritional content of snacks sold at supermarkets and coffee shops in the UK.

BACKGROUND: Snacking is associated with a higher daily energy intake and dietary guidelines recommend snacks of no more than 200 kcal for adults and 100 kcal for children. The present study examines the energy content, nutritional quality and price of single-serving snack food products sold by major supermarket and coffee shop chains in the UK. METHODS: Energy content, nutritional content and price of single-serving snack products were recorded in 2019 via the websites of 14 major chains (seven supermarkets; seven coffee shops). RESULTS: The mean energy content of all eligible snack products (n = 2283) was 186 kcal [95% confidence interval (CI) = 182-190]. The mean energy content of the snack products sold at coffee shops (n = 379; 282 kcal [95% CI = 269-295]) was significantly higher than the energy content of the snack products sold at supermarkets (n = 1904; 167 kcal [95% CI = 164-170]). Seventy nine % of supermarket snacks exceeded energy recommendations for children and 32% for adults. In coffee shops, 91% exceeded recommendations for children and 73% for adults. Forty one % of snacks were high in fat, 42% were high in saturated fat, 39% were high in sugar and 7% were high in salt. Cheaper snack products were more likely to be of lower nutritional quality. CONCLUSIONS: The high proportion of snack products that do not meet public health recommendations for energy content may contribute to the association between snacking and increased energy intake. Public health measures to increase the availability and reduce the price of snack products that meet public health energy content recommendations may reduce population-level obesity.

Socioeconomic position and the impact of increasing availability of lower energy meals vs. menu energy labelling on food choice: two randomized controlled trials in a virtual fast-food restaurant.

BACKGROUND: Food consumed outside of the home is often high in energy and population level interventions that reduce energy intake of people from both lower and higher socioeconomic position (SEP) are needed. There is a lack of evidence on the effectiveness and SEP equity of structural-based (e.g. increasing availability of lower energy options) and information provision (e.g. menu energy labelling) interventions on food choice. METHODS: Across two online experiments, participants of lower and higher SEP made meal choices in a novel virtual fast-food restaurant. To be eligible to take part, participants were required to be UK residents, aged 18 or above, fluent in English, have access to a computer with an internet connection and have no dietary restrictions. Participants were randomized to one of four conditions in a 2 × 2 between-subjects design: menu energy labelling present vs. absent and increased availability of lower energy options (75% of menu options lower energy) vs. baseline availability (25% of menu options lower energy). Participants also completed measures of executive function and food choice motives. RESULTS: The analysis of pooled data from both studies (n = 1743) showed that increasing the availability of lower energy options resulted in participants ordering meals with significantly less energy on average (- 71 kcal, p <  0.001, partial η2 = 0.024) and this effect was observed irrespective of participant SEP. Menu labelling had no significant effect on energy ordered (- 18 kcal, p = 0.116, partial η2 = 0.001) in participants from both higher and lower SEP. Furthermore, we found no evidence that executive function or food choice motives moderated the effect of increasing lower energy menu options or energy labelling on total energy ordered. CONCLUSIONS: In a virtual fast-food environment, energy labelling was ineffective in reducing total energy ordered for both higher and lower SEP participants. Increasing the availability of lower energy options had an equitable effect, reducing total energy ordered in participants from higher and lower SEP. TRIAL REGISTRATION: Study protocols and analysis plans were pre-registered on the Open Science Framework (https://osf.io/ajcr6/).

Learned pleasure from eating: An opportunity to promote healthy eating in children?

Across the lifespan, eating is a common everyday act driven by the search for pleasure and reinforced by experienced pleasure. Pleasure is an innate indicator of the satisfaction of physiological needs, in addition to other attributes. Pleasure from eating is also learned and contributes to the development of children's eating habits, which remain mostly stable until adulthood. Based on classical models of determinants of food consumption behaviour, we identified three dimensions of pleasure from eating learned during childhood: 1/the sensory dimension, i.e., pleasure from sensory sensations during food consumption; 2/the interpersonal dimension, i.e., pleasure from the social context of food consumption; and 3/the psychosocial dimension, i.e., pleasure from cognitive representations of food. The objective of this narrative review is to explore whether these three dimensions may play a role in promotion of healthy eating behaviour among children. Up to now, it was assumed that providing nutritional information, pointing out which types of foods are "good" or "bad" for health, would drive healthier food choices in children. Today, we know that such strategies based on a cognitive approach toward eating have a limited impact on healthy choices and can even be counter-productive, leading children to avoid healthy foods. In the context of increasing rates of childhood obesity, new perspectives are needed to build efficient interventions that might help children adopt a healthy diet. This review suggests new directions for further research to test the efficacy of novel interventions that emphasize pleasure from eating.

When do healthiness and liking drive children's food choices? The influence of social context and weight status.

Children identify liking and healthiness of foods as factors influencing their food choices. However, the food decision making process is also influenced by both personal characteristics and food contexts. The present study explored the influence of liking and perceived healthiness of foods in normal- and overweight children's food choices intentions in a pleasure-oriented social eating context and a health-oriented social eating context. Children aged from 6 to 11 years old (n = 63; 34 children who were of normal weight and 29 who were overweight) were asked to select 5 foods among 10, based on food pictures, to make up a snack that would be suitable for their birthday party or a nutrition class. In addition, they rated their liking and healthiness perception of the foods. No significant difference in food choices was found between children who were of normal weight and children who were overweight. Both groups of children chose more healthy food items in a health-oriented social context (i.e., a fictive nutrition class) than in a pleasure-oriented social context (i.e., a fictive birthday party). Moreover, only liking significantly predicted food choices in the pleasure-oriented social context whereas both healthiness and liking significantly predicted food choices in the health-oriented social context. Overall these results advance our understanding on how children make food decisions and inform strategies that may help children to adopt a healthy diet. Because liking predicted children's food choices in both eating contexts, emphasizing the "good" taste of healthy foods and providing children with healthy foods they like could be efficient strategies to promote healthy eating habits in children.

Do hedonic- versus nutrition-based attitudes toward food predict food choices? a cross-sectional study of 6- to 11-year-olds.

BACKGROUND: Implicit and explicit attitudes are potential precursors of food choices and combine affective and cognitive components that can vary in their relative dominance. Yet, the affective and cognitive components of attitudes toward food can lead to distinct predisposition toward a food item and potentially to different food choices. In the food domain, the affective component pertains to the hedonic tone of consumption, while the cognitive component encompasses nutritional value or health consequences of food. The present study investigated whether hedonic- versus nutrition-based implicit and/or explicit attitudes toward food predicts children's healthy versus unhealthy food choices. METHODS: A total of 63 children (age range = 6.3-11.5) participated in a 90-min session at 5 pm (i.e., afterschool snack time in France). The children were asked to choose five food items from a buffet featuring five healthy and five unhealthy sweet foods pretested as being highly liked. Children ate what they had chosen. Moreover, their implicit attitudes were assessed with a pairing task in which children were presented with 10 food triplets and asked to choose two food items that "best go together". For each triplet, foods could be paired according to their hedonic or nutritional characteristics. Explicit attitudes were assessed with a task in which children placed each of 48 food items into one of the following categories: "yummy", "yucky" (i.e., hedonic categories), "makes you strong", or "makes you fat" (i.e., nutritional categories). RESULTS: Both implicit and explicit attitudes significantly influenced children's food choices. We observed that children with more hedonic-based implicit or explicit attitudes toward food were more likely to choose healthy food options from the buffet. Conversely, children with both implicit and explicit nutrition-based attitudes chose less healthy foods. CONCLUSIONS: Hedonic-based attitudes toward food seem to drive healthier food choices in children compared with nutrition-based attitudes in this particular eating context. These findings suggest that pleasure from eating might be an ally with regard to healthy eating among children. Additional research is needed to understand the etiology of children's attitudes toward food in order to provide insights on how to shape adequate children's attitudes to guide them toward healthy food choices.

Explicit and implicit tasks for assessing hedonic-versus nutrition-based attitudes towards food in French children.

Attitudes are important precursors of behaviours. This study aims to compare the food attitudes (i.e., hedonic- and nutrition-based) of children using both an implicit pairing task and an explicit forced-choice categorization task suitable for the cognitive abilities of 5- to 11-year-olds. A dominance of hedonically driven attitudes was expected for all ages in the pairing task, designed to elicit affective and spontaneous answers, whereas a progressive emergence of nutrition-based attitudes was expected in the categorization task, designed to involve deliberate analyses of the costs/benefits of foods. An additional exploratory goal was to evaluate differences in the attitudes of normal and overweight children in both tasks. Children from 3 school levels (n = 194; mean age = 8.03 years) were individually tested on computers in their schools. They performed a pairing task in which the tendencies to associate foods with nutritional vs. culinary contexts were assessed. Next, they were asked to categorize each food into one of the following four categories: "yummy", "yucky" (i.e., hedonic categories), "makes you strong", or"makes you fat" (i.e., nutritional categories). The hedonic/culinary pairs were very frequently selected (81% on average), and this frequency significantly increased through school levels. In contrast, in the categorization task, a significant increase in nutrition-driven categorizations with school level was observed. Additional analyses revealed no differences in the food attitudes between the normal and overweight children in the pairing task, and a tendency towards lower hedonic categorizations among the overweight children. Culinary associations can reflect cultural learning in the French context where food pleasure is dominant. In contrast, the progressive emergence of cognitively driven attitudes with age may reflect the cognitive development of children who are more reasonable and influenced by social norms.

Semaglutide as a potential treatment for obesity in Smith-Kingsmore syndrome (SKS) patients: A mosaic mutation case report.

We present for the first-time efficacy and tolerability of GLP-1-RA (Semaglutide) in Smith-Kingsmore syndrome (SKS). SKS is a rare genetic disorder characterized by intellectual disability, macrocephaly, seizures and distinctive facial features due to MTOR gene mutation. We present a 22-year-old woman with mosaic SKS and severe obesity (Body Mass Index ≥40 kg/m²), treated with semaglutide. She achieved a 9 kg (7.44%) weight loss over 12 months without adverse effects.This case highlights semaglutide's potential in managing obesity in SKS patients, emphasizing the need for further research in this rare genetic disorder.
