Summary: In the context of a worldwide obesity epidemic, healthcare providers play a key role in obesity management. Knowledge of current guidelines and attitudes to prevent stigmatization are especially important. This study aimed to assess knowledge, attitudes, beliefs, perception of opportunity for intervention, declared practices and need for training and material of nurses and physicians about obesity in a Swiss University Hospital. A total of 834 physicians and nurses filled an online survey. The questionnaire was based on literature, exploratory interviews and expert committee review. It was pre‐tested with 15 physicians and nurses. Participants declared a low level of negative attitudes towards individuals living with obesity. However, the results highlighted a lack of knowledge to diagnose obesity in adults and children, as well as confidence and training to care of patients with obesity. One‐third of providers did not know how to calculate body mass index. Half of providers felt it was part of their role to take care of patients with obesity, even if 55% of them had the feeling that they did not have adequate training. Nurses and physicians working in a university hospital showed a low level of negative attitudes but a lack of knowledge and skills on obesity management. Training should be improved in this population to insure adequate and coherent messages and equal access to evidence‐based treatment for patients living with obesity.

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.

Nutritional management is an important component of the treatment of pediatric overweight and obesity, but clinicians struggle to keep abreast with the abundant literature. Therefore, our aim is to provide a tool that integrates the current recommendations and clinical expertise to assist dietitians and other practitioners in their decision making about the nutritional management of pediatric overweight and obesity. To construct this practice-based evidence-informed framework, we conducted a systematic review of the guidelines on nutritional management of pediatric overweight or obesity in 2 databases and in the grey literature. We analyzed and synthesized recommendations of 17 guidelines. We selected the recommendations that were common to at least 30% of the guidelines and added by consensus the recommendations relevant to clinical expertise. Finally, we structured the framework according to the Nutritional Care Process in collaboration with a specialized team of dietitians who assessed its validity in clinical practice. The framework contributes to facilitate the integration of evidence-based practice for dietitians by synthesizing the current evidence, supporting clinical expertise, and promoting structured care following Nutrition Care Process model for children and adolescents with obesity.

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.
