Objective: To examine the associations of perceived physical environmental factors (availability of physical activity (PA) attributes at home, PA facilities in the neighbourhood, neighbourhood pleasantness and safety) and social environmental factors (parental sports behaviour and parental rule regarding sports participation) with adolescent leisure-time sports participation, and to explore whether the associations found were mediated by individual cognitions as derived from the theory of planned behaviour (TPB).Design: Cross-sectional study.Setting: In school-year 2005/2006 adolescents from seventeen schools in Rotterdam, the Netherlands, completed a questionnaire during school hours that included self-reported measures of leisure-time sports participation, perceived physical environmental factors and TPB variables. Information about parental sports behaviour and parental rule was obtained from a questionnaire that was completed by one parent of the adolescents.Subjects: Data were collected from 584 adolescent-parent combinations.Results: Data were analysed with multi-level logistic regression analyses. Availability of PA attributes at home (OR = 1·26), parents' sports behaviour (OR = 2·03) and parental rule (OR = 1·64) were associated with a higher likelihood of adolescents' leisure-time sports participation. These associations were partly mediated by attitude and intention.Conclusions: Adolescents were more likely to engage in leisure-time sports when PA attributes were available at home, when parents participated in sports activities and had a rule about their offspring participation in sports activities. These associations were partly mediated by attitude and intention. These results suggest that parents can importantly promote sports participation among their offspring by making sports activities accessible and a family routine. [ABSTRACT FROM AUTHOR]

Objective: This study examined reasons for specialty choice among Swiss residents (post graduate doctors training in specialties). Methods: In 2006, a questionnaire was sent to 8626 Swiss residents registered in postgraduate medical training programmes to obtain specialist qualifications. The response rate was 65% ( n = 5631). As residents are allowed to decide on the specialty they want to acquire later in the training process, only residents who had already chosen a specific specialty were included ( n = 5038). In responding, residents rated the importance of 19 factors in making their choice of specialty. Categorical principal component analysis was conducted to obtain underlying dimensions within the reasons for choice. A two-way analysis of variance was performed for each dimension to compare the mean object scores for the 10 specialties chosen by the most residents and to examine possible interactions by gender and year of graduation. Contrasts between the specialties were analysed with Scheffe post hoc tests. Results: Categorical principal component analyses yielded three factors underlying residents' choice of specialty, which explained 40.8% of the variance in responses: work and time-related aspects; career-related aspects, and patient orientation. Women considered work and time-related aspects and patient orientation to be more important factors in their choice, and career-related aspects to be less important, than did men. Career-related aspects became less important with advancing training status. Conclusions: This study showed that reasons for specialty choice differ according to gender, year of graduation and specialty. With progressing training status, gender differences in reasons for choice and specialty choice may become more pronounced, especially regarding career aspects, which may lead to a change in preferred specialty. Therefore, a modular constructed postgraduate training programme might give residents the flexibility to change from one specialty to another. [ABSTRACT FROM AUTHOR]

The purpose of this study was to investigate whether perceived parenting practices and parenting style dimensions (strictness and involvement) are associated with adolescents' consumption of sugar-sweetened beverages. In this cross-sectional study, secondary school students (n = 383, mean age 13.5 years) completed a self-administered questionnaire on their consumption of sugar-sweetened beverages, attitude, social influences, self-efficacy, habit strength, food-related parenting practices and the general parenting style dimensions of 'strictness' and 'involvement'. Data were analyzed using multiple linear regression analyses. More restrictive parenting practices were associated with lower consumption of sugar-sweetened beverages (beta = -38.0 ml; 95% CI = -48.1, -28.0). This association was highly mediated ( approximately 55%) by attitude, self-efficacy and modeling from parents. Nevertheless, a significant direct effect remained (beta = -17.1 ml; 95% CI = -27.2, -6.90). Interactions between perceived parenting style and parenting practices showed that the association between parenting practices and sugar-sweetened beverage consumption was stronger among adolescents who perceived their parents as being moderately strict and highly involved. Parents influence their children's sugar-sweetened beverage consumption and should therefore be involved in interventions aimed at changing dietary behaviors. Interventions aimed at the promotion of healthy parenting practices will improve when they are tailored to the general parenting style of the participants. [ABSTRACT FROM AUTHOR]

There is increasing interest in the role the environment plays in shaping the dietary behavior of youth, particularly in the context of obesity prevention. An overview of environmental factors associated with obesity-related dietary behaviors among youth is needed to inform the development of interventions. A systematic review of observational studies on environmental correlates of energy, fat, fruit/vegetable, snack/fast food and soft drink intakes in children (4-12 years) and adolescents (13-18 years) was conducted. The results were summarized using the analysis grid for environments linked to obesity. The 58 papers reviewed mostly focused on sociocultural and economical-environmental factors at the household level. The most consistent associations were found between parental intake and children's fat, fruit/vegetable intakes, parent and sibling intake with adolescent's energy and fat intakes and parental education with adolescent's fruit/vegetable intake. A less consistent but positive association was found for availability and accessibility on children's fruit/vegetable intake. Environmental factors are predominantly studied at the household level and focus on sociocultural and economic aspects. Most consistent associations were found for parental influences (parental intake and education). More studies examining environmental factors using longitudinal study designs and validated measures are needed for solid evidence to inform interventions. [ABSTRACT FROM AUTHOR]

Background: Food-based dietary guidelines (FBDGs) provide advice on what constitutes a healthy diet, influencing both decision-making at the policy level, and educational programs addressed to consumers. There is a growing body of literature that allows to estimate the health and environmental impacts of the wide adoption of FBDG at the country and global levels. This unlocks the possibility of evaluating the most sustainable dietary guidelines from a communication perspective. This study aims at answering what are the key converging messages and main differences in the communication of FBDG that have a high environmental potential, and what of those FBDG do communicate a sustainability purpose in an explicit way. Methods: A mixed-method comparative review of FBDGs with a two-stage sampling process was developed. Building on Springmann et al (2020) we identified the countries where the wide population adoption of dietary guidelines would have the highest potential of reducing food-related greenhouse gas emissions (GHGe) while delivering positive health outcomes. In a second stage, a purposeful sample of FBDGs was designed to cover countries from different WHO regions, income levels, and languages. Results: This study is in progress and results are preliminary. Out of the initial sample of identified FBDG with a GHGe reduction potential of more than 25 percent, a few of them, Germany, Brazil, Sweden, Netherlands, and France had been previously identified in the literature as having sustainability-based recommendations. Other guidelines with similar GHGe reduction potential, such as those of Switzerland and Italy also address sustainability in an explicit way. Conclusions: FBDGs have been traditionally focused on health and nutrition messages. Several countries have updated recommendations considering the environmental impacts of food consumption. Not all the FBDG with a high environmental potential explicitly communicate sustainability concerns. Key messages: Several countries can improve their health and climate change outcomes by promoting a wider adoption of their official dietary guidelines. Communication is a key aspect of this process.

Abstract Background This study examined the associations of the perceived and objective environment with adolescent engagement in sports activities and walking and cycling in leisure time. It also explored the degree of agreement between objective and perceived availability of physical activity (PA) facilities in neighborhoods. Methods Cross-sectional data on physical activity, the perceived availability of physical activity opportunities (perceived physical environment) was assessed through a questionnaire and the objective availability of PA opportunities (objective physical environment) was obtained through GIS data. The final sample included 654 adolescents with a mean age of 14.1 (SD = 1.2) years. Results Perceived availability of sports facilities and parks was significantly associated with engaging in sports (OR: 1.73; 95% CI: 1.16-2.56) and with walking and cycling in leisure time (OR: 1.66; 95% CI: 1.07-2.57) respectively. Agreement between objective and perceived environment was low to moderate with Kappa values ranging from -0.005 to 0.053. Conclusion The perceived environment was the stronger correlate of PA behavior among adolescents. There were substantial differences between assessments of objective and perceived physical environment.

Objective: To examine the factors that make such programs successful, this systematic review compared the outcomes of children's participation in cooking interventions based on intervention characteristics., Design: Systematic review of randomized controlled trials of children's participation in cooking interventions published between 1998 and 2022 guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement., Setting: All settings PARTICIPANTS: Children and parents., Main Outcome Measures: Cooking skills, food acceptance and dietary behavior., Analysis: Systematic search of 1,104 articles and review of 23 studies (42 articles) meeting inclusion criteria., Results: Interventions varied in participant age, settings, cooking sessions, and program length. Knowledge of cooking skills, self-efficacy, and child cooking involvement were the most frequent positive outcomes; improvements in dietary intake were rarely achieved. Seven studies had a high rating for research quality., Conclusion and Implications: Lack of standardized assessment, large variability in program characteristics, and insufficient intervention description made it difficult to discern best practices for children's cooking programs. Improvements in intervention development and measurement instruments are needed. Interventions that include hands-on cooking lessons seem promising in improving knowledge and self-efficacy; however, further exploration is required on the factors that make cooking programs successful in the long term., (Copyright © 2024 The Authors.

Objectives: As there is no ranking designed for schools of Public Health, the aim of this project was to create one. Methods: To design the Public Health Academic Ranking (PHAR), we used the InCites Benchmarking and Analytics™ software and the Web Of Science™ Core Collection database. We collected bibliometric data on 26 schools of Public Health from each continent, between August and September 2022. We included 11 research indicators/scores, covering four criteria (productivity, quality, accessibility for readers, international collaboration), for the period 2017-2021. For the Swiss School of Public Health (SSPH+), a network gathering faculties across different universities, a specific methodology was used, with member-specific research queries. Results: The five top schools of the PHAR were: London School of Hygiene and Tropical Medicine, Public Health Foundation of India, Harvard T.H. Chan School of Public Health, SSPH+, Johns Hopkins Bloomberg School of Public Health. Conclusion: The PHAR allows worldwide bibliometric ordering of schools of Public Health. As this is a pilot project, the results must be taken with caution. This article aims to critically discuss its methodology and future improvements., Competing Interests: The authors declare that they do not have any conflicts of interest., (Copyright © 2024 Dugerdil, Babington-Ashaye, Bochud, Chan, Chiolero, Gerber-Grote, Künzli, Paradis, Puhan, Suggs, Van der Horst, Escher and Flahault.)

Background: Vegan diets have recently gained popularity in Switzerland as well as globally. The aim of the present study was to develop a diet quality score for vegans (DQS-V) based on the Swiss dietary recommendations for vegans., Methods: The dataset included 52 healthy vegan adults. Dietary intake data were assessed by three-day weighed food records. Body weight and height were measured, and a venous blood sample for the analysis of vitamin and mineral status was collected. Spearman rank correlation coefficients were used due to not-normally distributed data. Dietary patterns were identified using principal component analysis (PCA)., Results: The DQS-V score (mean ± SD) was 48.9 ± 14.7. Most vegans adhered to the recommended portions of vegetables, vitamin C-rich vegetables, fruits, omega-3-rich nuts, fats and oils, and iodized salt. However, the intake of green leafy vegetables, vitamin C-rich fruits, wholegrains, legumes, nuts and seeds, selenium-rich nuts, zero caloric liquid, and calcium-fortified foods was suboptimal. The sample overconsumed sweet-, salty-, fried foods, and alcohol. The DQS-V had a significantly positive correlation with intakes of fibre, polyunsaturated fatty acids, potassium, zinc, and phosphorus intakes (p's < 0.05) but was negatively correlated with vitamin B12 and niacin intakes (p's < 0.05). Two dietary patterns were derived from PCA: 1) refined grains and sweets and 2) wholegrains and nuts. The correlation between the DQS-V and the first dietary pattern was negative (- 0.41, p = 0.004) and positive for the second dietary pattern (0.37, p = 0.01). The refined grains and sweets dietary pattern was inversely correlated with beta-carotene status (- 0.41, p = 0.004) and vitamin C status (r = - 0.51, p = 0.0002)., Conclusion: The newly developed DQS-V provides a single score for estimating diet quality among vegan adults. Further validation studies examining the DQS-V in relation to an independent dietary assessment method and to biomarkers of nutritional intake and status are still needed before the general application of the DQS-V., (© 2024.

Globally, millions of lives are impacted every year by infectious diseases outbreaks. Comprehensive and innovative surveillance strategies aiming at early alert and timely containment of emerging and reemerging pathogens are a pressing priority. Shortcomings and delays in current pathogen surveillance practices further disturbed informing responses, interventions, and mitigation of recent pandemics, including H1N1 influenza and SARS-CoV-2. We present the design principles of the architecture for an early-alert surveillance system that leverages the vast available data landscape, including syndromic data from primary health care, drug sales, and rumors from the lay media and social media to identify areas with an increased number of cases of respiratory disease. In these potentially affected areas, an intensive and fast sample collection and advanced high-throughput genome sequencing analyses would inform on circulating known or novel pathogens by metagenomics-enabled pathogen characterization. Concurrently, the integration of bioclimatic and socioeconomic data, as well as transportation and mobility network data, into a data analytics platform, coupled with advanced mathematical modeling using artificial intelligence or machine learning, will enable more accurate estimation of outbreak spread risk. Such an approach aims to readily identify and characterize regions in the early stages of an outbreak development, as well as model risk and patterns of spread, informing targeted mitigation and control measures. A fully operational system must integrate diverse and robust data streams to translate data into actionable intelligence and actions, ultimately paving the way toward constructing next-generation surveillance systems., (©Pablo Ivan P Ramos, Izabel Marcilio, Ana I Bento, Gerson O Penna, Juliane F de Oliveira, Ricardo Khouri, Roberto F S Andrade, Roberto P Carreiro, Vinicius de A Oliveira, Luiz Augusto C Galvão, Luiz Landau, Mauricio L Barreto, Kay van der Horst, Manoel Barral-Netto, ÆSOP Collaborating Teams.

Background: Currently, over 4000 bariatric procedures are performed annually in Switzerland. To improve outcomes, patients need to have good knowledge regarding postoperative nutrition. To potentially provide them with knowledge between dietetic consultations, a health bot (HB) was created. The HB can answer bariatric nutrition questions in writing based on artificial intelligence., Objective: This study aims to evaluate the usability and perception of the HB among patients receiving bariatric care., Methods: Patients before or after bariatric surgery tested the HB. A mixed methods approach was used, which consisted of a questionnaire and qualitative interviews before and after testing the HB. The dimensions usability of, usefulness of, satisfaction with, and ease of use of the HB, among others, were measured. Data were analyzed using R Studio (R Studio Inc) and Excel (Microsoft Corp). The interviews were transcribed and a summary inductive content analysis was performed., Results: A total of 12 patients (female: n=8, 67%; male: n=4, 33%) were included. The results showed excellent usability with a mean usability score of 87 (SD 12.5; range 57.5-100) out of 100. Other dimensions of acceptability included usefulness (mean 5.28, SD 2.02 out of 7), satisfaction (mean 5.75, SD 1.68 out of 7), and learnability (mean 6.26, SD 1.5 out of 7). The concept of the HB and availability of reliable nutrition information were perceived as desirable (mean 5.5, SD 1.64 out of 7). Weaknesses were identified in the response accuracy, limited knowledge, and design of the HB., Conclusions: The HB's ease of use and usability were evaluated to be positive; response accuracy, topic selection, and design should be optimized in a next step. The perceptions of nutrition professionals and the impact on patient care and the nutrition knowledge of participants need to be examined in further studies., (©Marina Beyeler, Corinne Légeret, Fabian Kiwitz, Klazine van der Horst.

A healthy diet can help to prevent or manage many important conditions and diseases, particularly obesity, malnutrition, and diabetes. Recent advancements in artificial intelligence and smartphone technologies have enabled applications to conduct automatic nutritional assessment from meal images, providing a convenient, efficient, and accurate method for continuous diet evaluation. We now extend the goFOOD TM automatic system to perform food segmentation, recognition, volume, as well as calorie and macro-nutrient estimation from single images that are captured by a smartphone. In order to assess our system's performance, we conducted a feasibility study with 50 participants from Switzerland. We recorded their meals for one day and then dietitians carried out a 24 h recall. We retrospectively analysed the collected images to assess the nutritional content of the meals. By comparing our results with the dietitians' estimations, we demonstrated that the newly introduced system has comparable energy and macronutrient estimation performance with the previous method; however, it only requires a single image instead of two. The system can be applied in a real-life scenarios, and it can be easily used to assess dietary intake. This system could help individuals gain a better understanding of their dietary consumption. Additionally, it could serve as a valuable resource for dietitians, and could contribute to nutritional research.

Background: Diet quality indexes are useful tools to measure diet quality because they compare dietary intakes against recommendations. A dietary quality index for Asian preschool-aged children is lacking., Objective: The aims of this study were to develop and evaluate a dietary quality index for preschool-aged children (ie, the DQI-5) based on Singapore dietary recommendations and to examine diet quality in a cohort of 5-year-old children. An additional aim was to assess associations between sociodemographic characteristics and DQI-5 scores., Design: A secondary analysis was conducted using dietary intake of children from the Growing Up in Singapore Towards healthy Outcomes mother-offspring cohort assessed in 2015-2016 using a validated food frequency questionnaire. The sociodemographic data were assessed at recruitment between June 2009 and September 2010. The DQI-5 was evaluated using a construct validity approach, whereby nutrition parameters associated with diet quality were studied., Participants and Setting: Participants were 767 Singaporean children aged 5 years of Chinese, Malay, or Indian ethnicity., Main Outcome Measures: The main outcome measures were the DQI-5 scores and the sociodemographic characteristics associated with diet quality., Statistical Analyses Performed: Kruskal-Wallis tests were used to evaluate differences in adherence to dietary recommendations across DQI-5 tertiles. Linear multiple regression analysis was performed to identify sociodemographic characteristics that were associated with diet quality in the children., Results: The DQI-5 consists of 12 food and nutrient components, with a minimum score of zero and a maximum score of 110 points. The higher scores indicate a healthier diet, the mean ± SD DQI-5 score for the children was 61.6 ± 13.2. DQI-5 components with low scores included whole grains, vegetables, and fatty acid ratio, whereas total rice and alternatives and milk and dairy products components were overconsumed by 18% and 24.4% of children, respectively. Children with higher scores were more likely to meet dietary recommendations and had higher intake of nutrients such as dietary fiber, iron, vitamin A, and beta carotene. Children whose mothers were of Malay ethnicity and whose mothers had low income, an education below university, and shared primary caregiver responsibilities were more likely to have lower DQI-5 scores., Conclusions: The DQI-5 scores revealed diets to be low for several components and excessive for a few. The DQI-5 developed for preschool-aged children in Singapore had adequate construct validity., (Copyright © 2023. Published by Elsevier Inc.)

Objective: To develop and evaluate the feasibility of a mobile application in Swiss households and assess its impact on dietary behavior and food acceptability between children who cooked with limited parental support (intervention group) with children who were not involved in cooking (control group)., Methods: A ten-week randomized controlled trial was conducted online in 2020. Parents were given access to a mobile-app with ten recipes. Each recipe emphasized one of two generally disliked foods (Brussels sprouts or whole-meal pasta). Parents photographed and weighed the food components from the child's plate and reported whether their child liked the meal and target food. The main outcome measures were target food intake and acceptability analyzed through descriptive analysis for pre-post changes., Results: Of 24 parents who completed the baseline questionnaires, 18 parents and their children (median age: 8 years) completed the evaluation phase. Mean child baseline Brussel sprouts and whole-meal pasta intakes were 19.0 ± 24.2 g and 86.0 ± 69.7 g per meal, respectively. No meaningful differences in intake were found post-intervention or between groups. More children reported a neutral or positive liking towards the whole-meal pasta in the intervention group compared to those in the control group. No change was found for liking of Brussel sprouts., Conclusions for Practice: The intervention was found to be feasible however more studies on larger samples are needed to validate feasibility. Integrating digital interventions in the home and promoting meal preparation may improve child reported acceptance of some healthy foods. Using such technology may save time for parents and engage families in consuming healthier meals., Competing Interests: Competing interestsNo conflicts of interest or competing interests apply., (© The Author(s) 2023.)

Culinary education programs are generally designed to improve participants' food and cooking skills, with or without consideration to influencing diet quality or health. No published methods exist to guide food and cooking skills' content priorities within culinary education programs that target improved diet quality and health. To address this gap, an international team of cooking and nutrition education experts developed the Cooking Education (Cook-Ed TM ) matrix. International food-based dietary guidelines were reviewed to determine common food groups. A six-section matrix was drafted including skill focus points for: (1) Kitchen safety, (2) Food safety, (3) General food skills, (4) Food group specific food skills, (5) General cooking skills, (6) Food group specific cooking skills. A modified e-Delphi method with three consultation rounds was used to reach consensus on the Cook-Ed TM matrix structure, skill focus points included, and their order. The final Cook-Ed TM matrix includes 117 skill focus points. The matrix guides program providers in selecting the most suitable skills to consider for their programs to improve dietary and health outcomes, while considering available resources, participant needs, and sustainable nutrition principles. Users can adapt the Cook-Ed TM matrix to regional food-based dietary guidelines and food cultures.

Background: Technological advancements have enabled nutrient estimation by smartphone apps such as goFOOD. This is an artificial intelligence-based smartphone system, which uses food images or video captured by the user as input and then translates these into estimates of nutrient content. The quality of the data is highly dependent on the images the user records. This can lead to a major loss of data and impaired quality. Instead of removing these data from the study, in-depth analysis is needed to explore common mistakes and to use them for further improvement of automated apps for nutrition assessment., Objective: The aim of this study is to analyze common mistakes made by participants using the goFOOD Lite app, a version of goFOOD, which was designed for food-logging, but without providing results to the users, to improve both the instructions provided and the automated functionalities of the app., Methods: The 48 study participants were given face-to-face instructions for goFOOD Lite and were asked to record 2 pictures (1 recording) before and 2 pictures (1 recording) after the daily consumption of each food or beverage, using a reference card as a fiducial marker. All pictures that were discarded for processing due to mistakes were analyzed to record the main mistakes made by users., Results: Of the 468 recordings of nonpackaged food items captured by the app, 60 (12.8%) had to be discarded due to errors in the capturing procedure. The principal problems were as follows: wrong fiducial marker or improper marker use (19 recordings), plate issues such as a noncompatible or nonvisible plate (8 recordings), a combination of various issues (17 recordings), and other reasons such as obstacles (hand) in front of the camera or matching recording pairs (16 recordings)., Conclusions: No other study has focused on the principal problems in the use of automatic apps for assessing nutritional intake. This study shows that it is important to provide study participants with detailed instructions if high-quality data are to be obtained. Future developments could focus on making it easier to recognize food on various plates from its color or shape and on exploring alternatives to using fiducial markers. It is also essential for future studies to understand the training needed by the participants as well as to enhance the app's user-friendliness and to develop automatic image checks based on participant feedback., (©Maria F Vasiloglou, Klazine van der Horst, Thomai Stathopoulou, Michael P Jaeggi, Giulia S Tedde, Ya Lu, Stavroula Mougiakakou.

Introduction: Quantifying Home Cooking EnviRonments has applications in nutrition epidemiology, health promotion, and nutrition interventions. This study aimed to develop a tool to quantify household cooking environments and establish its content validity, face validity, and inter-rater agreement., Methods: The Home Cooking EnviRonment and equipment Inventory observation form (Home-CookERI™) was developed as a 24-question (91-item) online survey. Items included domestic spaces and resources for storage, disposal, preparation, and cooking of food or non-alcoholic beverages. Home-CookERI TM was piloted to assess content validity, face validity, and usability with six Australian experts (i.e., dietitians, nutrition researchers, chefs, a food technology teacher, and a kitchen designer) and 13 laypersons. Pilot participants provided feedback in a 10 min telephone interview. Home-CookERI™ was modified to an 89-item survey in line with the pilot findings. Inter-rater agreement was examined between two trained raters in 33 unique Australian households. Raters were required to observe each item before recording a response. Home occupants were instructed to only assist with locating items if asked. Raters were blinded to each other's responses. Inter-rater agreement was calculated by Cohen's Kappa coefficient (κ) for each item. To optimize κ, similar items were grouped together reducing the number of items to 81., Results: Home-CookERI TM had excellent content and face validity with responding participants; all 24 questions were both clear and relevant (X 2 (1, n = 19; 19.0, p = 0.392)). Inter-rater agreement for the modified 81-item Home-CookERI™ was almost-perfect to perfect for 46% of kitchen items ( n = 37 items, κ = 0.81-1), moderate to substantial for 28% ( n = 23, κ = 0.51-0.8), slight to fair for 15% ( n = 12, κ = 0.01-0.5), and chance or worse for 11% of items ( n = 9, κ ≤ 0.0). Home-CookERI TM was further optimized by reduction to a 77-item version, which is now available to researchers., Conclusion: Home-CookERI™ is a comprehensive tool for quantifying Australian household cooking environments. It has excellent face and content validity and moderate to perfect inter-rater agreement for almost three-quarters of included kitchen items. To expand Home-CookERI™ applications, a home occupant self-completion version is planned for validation.

Objective: To assess whether feeding questionnaire responses reflect observed mealtime behavior., Design: Cross-sectional associations between self-reported and observed behaviors., Setting: Participants' homes., Participants: Parents (n = 75) of toddlers (mean age = 24.7 months) in the US., Main Outcome Measures: Feeding behavior questionnaires and coded videos of children's dinner meals., Analysis: Parents' questionnaire responses of "never" (or "rarely") considered consistent with video observation if behavior was not observed; responses of "always" (or "most of the time") if behavior observed at least once. Proportion (%) of participants observed performing each behavior was calculated for the groups of parents reporting that they "never," "sometimes," or "always" used that feeding practice. These were compared across the 3 response groups., Results: Parents reported 6 behaviors consistently (≥70% agreement): allowing child to eat as much as wanted, helping child eat, prompting child to eat, television/screens on during meal, nonfood rewards, and hurrying child. The remaining 8 behaviors fell below the threshold. For many behaviors, all response groups (never, sometimes, always) had similar rates of participants demonstrating the behavior. Only 5 behaviors had observed rates falling in the expected direction (frequency of always > sometimes > never). For some behaviors, the "sometimes" group had a higher (eg, clean plate) or lower (praise) frequency than the other 2 groups., Conclusions and Implications: Self-reported questionnaire responses predicted whether some, but not all, behaviors were observed. Parents' use of "sometimes" remains difficult to interpret as parents may use "sometimes" inconsistently across behaviors and perhaps to mitigate socially undesirable responses. Self-reports of "sometimes" performing a behavior may have limited utility for prediction of behavior and likely requires additional exploration with the respondent., (Copyright © 2019 Society for Nutrition Education and Behavior.

The increase in packaged food and beverage portion sizes has been identified as a potential factor implicated in the rise of the prevalence of obesity. In this context, the objective of this systematic scoping review was to investigate how healthy adults perceive and interpret serving size information on food packages and how this influences product perception and consumption. Such knowledge is needed to improve food labelling understanding and guide consumers toward healthier portion size choices. A search of seven databases (2010 to April 2019) provided the records for title and abstract screening, with relevant articles assessed for eligibility in the full-text. Fourteen articles met the inclusion criteria, with relevant data extracted by one reviewer and checked for consistency by a second reviewer. Twelve studies were conducted in North America, where the government regulates serving size information. Several studies reported a poor understanding of serving size labelling. Indeed, consumers interpreted the labelled serving size as a recommended serving for dietary guidelines for healthy eating rather than a typical consumption unit, which is set by the manufacturer or regulated in some countries such as in the U.S. and Canada. Not all studies assessed consumption; however, larger labelled serving sizes resulted in larger self-selected portion sizes in three studies. However, another study performed on confectionary reported the opposite effect, with larger labelled serving sizes leading to reduced consumption. The limited number of included studies showed that labelled serving size affects portion size selection and consumption, and that any labelled serving size format changes may result in increased portion size selection, energy intake and thus contribute to the rise of the prevalence of overweight and obesity. Research to test cross-continentally labelled serving size format changes within experimental and natural settings (e.g., at home) are needed. In addition, tailored, comprehensive and serving-size-specific food literacy initiatives need to be evaluated to provide recommendations for effective serving size labelling. This is required to ensure the correct understanding of nutritional content, as well as informing food choices and consumption, for both core foods and discretionary foods.

Objective: To evaluate the 2016 International Chefs Day cooking workshops Art on a Plate., Design: Nonexperimental pretest-posttest design SETTING: Art on a Plate workshops with children from 14 countries in Asia, America, and Europe., Participants: A total of 433 workshop participants aged 4-14 years (mean age, 8.6 years)., Intervention: Instructed by a chef, children in the workshops created a self-chosen design on their plate with a spinach-fruit salad., Main Outcome Measures: Before and after the workshop, a questionnaire assessing liking and willingness to eat or taste; hunger was assessed using the Teddy the Bear method and emotions were assessed using the Self-assessment Manikin. The event coordinator evaluated salad intake., Analysis: Linear and generalized linear (logit) mixed models were used to test statistical differences before and after the workshop., Results: The workshop resulted in a small increase in liking (n = 409; P = .02) and person control (n = 375; P < .001) and a decrease in hunger (n = 379; P < .001). A total of 30% of children increased their liking scores, 18% decreased them, and 52% did not change them. Significant associations of liking and change in liking with salad intake were in the expected direction., Conclusion and Implications: This study showed the positive effect of a cooking workshop on children's salad liking across a selection of countries worldwide. Further research and novel methods are needed to evaluate the long-term effectiveness of cooking activities in real-life settings across countries., (Copyright © 2019 The Authors.
