RÉSUMÉ

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.

RÉSUMÉ

Several tools assessing diet quality have been developed over the last decades, but their use in public health and clinical practice is limited because they necessitate detailed quantitative assessment of food intake. Our goal was to develop and validate a score (Score d'Alimentation Saine, SCASA) based on a short self-administrated online questionnaire to assess overall diet quality. SCASA targets the adult population in French-speaking Switzerland, but it was designed in a way enabling its adaptation for other regions. The choice of the items involved experts and lay volunteers. Construct validation and inter-method reliability were assessed by screening meal plans and by comparing the self-rated scores with food-record derived scores (kappa and Bland-Altman). SCASA (17 components) discriminated adequately balanced from imbalanced meal plans (93-95% and 44-46% of maximal score). Agreement between self-assessed and food record-based scores ranged between >90% (3 items), 80-89% (3 items), 70-79% (4 items), and <70% (5 items). The Bland-Altman plot showed a mean difference of -1.60 (95% CI -2.36 to -0.84), indicating a slight overestimation of the self-assessed diet quality compared to the food record. SCASA offers a reliable way to assess overall diet quality without requiring burdensome data collection or nutrient calculations.

RÉSUMÉ

The enthusiasm for nutritional supplements among athletes of any level seems inversely correlated to the real impact of these products; or at least this might be concluded after reading most systematic reviews and guidelines. Despite being frequently consumed, the supplements that have shown a positive effect on health or performance are rare. However, specific situations can require a supplementation, and this article outlines how to identify these situations and how to pick the right supplement for each condition. We also discuss the reason why providing evidence for an effect on health or performance is particularly challenging in this field.


L'enthousiasme des sportifs à l'égard des compléments alimentaires est-il inversement proportionnel à l'impact de ces substances ? C'est ce que l'on pourrait conclure à la lecture des essais randomisés et des guidelines. Malgré une prévalence de consommation élevée, rares sont les suppléments pour lesquels il existe un effet avéré. Dans certaines situations, une supplémentation peut être toutefois utile, voire nécessaire. Comment les identifier ? Quels suppléments ont un effet ergogène, et dans quelles conditions ? Cet article répond à ces questions et explicite également pourquoi il est particulièrement difficile de faire la preuve de l'efficacité de ces produits.

RÉSUMÉ

The World Health Organization (WHO) recommends reducing free sugars to less than 10% of total energy intake (TEI) due to their potential implications in weight gain and dental caries. Our objectives were to (1) estimate the intake of total, added, and free sugars, (2) define the main sugar sources, and (3) evaluate the adherence to sugar guidelines. The first national nutrition survey 2014-2015 included non-institutional adults aged 18-75 years. Diet was assessed with two non-consecutive 24-hour dietary recalls in 2057 participants. Added and free sugar content was systematically estimated by two dietitians using available information from the manufacturer and/or standard recipe/composition. Usual daily intake distributions were modeled and weighted for sampling design, non-response, weekdays, and seasons. Total, added, and free sugar intake was respectively 107 g (±44), 53 g (±36), and 65 g (±40), representing 19%, 9%, and 11% of TEI. Sugar consumption was higher among younger adults and lower among people living in the Italian-speaking region. The three main food sources of free sugars were: (1) sweet products (47% of total free sugars), in particular sweet spreads (15%) and cakes/cookies (11%); (2) beverages (29%), mainly fruit and vegetable juices (13%), and sugar-sweetened beverages (12%, but 20% in younger adults); and (3) dairy products (9%), with yogurt accounting for 6%. Respectively, 44% of women and 45% of men had free sugar intake below 10% of TEI. Of people aged between 18-29, 30-64, and 65-75 years, 36%, 45%, and 53% had free sugar intake below 10% of TEI, respectively. The prevalence of Swiss people with free sugar intake that was <5% of the TEI was 8%. Adherence to the WHO recommendations guidelines was generally low in Switzerland, particularly among young adults, and in line with other high-income countries.

RÉSUMÉ

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.

RÉSUMÉ

OBJECTIVE: To assess dietary intake, eating patterns, physical activity and eating behaviors, and to explore strategies and perceptions of the experience of weight maintenance in weight loss maintainers (weight loss maintenance (WLM) ≥ 10% weight loss maintained for ≥1 year) and in matched controls with a lifetime stable normal weight. METHODS: Volunteers (32) were recruited by a snowball procedure in this cross-sectional, mixed-methods study. Diet, physical activity, and eating behaviors were assessed with validated questionnaires. Strategies and experiences were investigated during interviews. Descriptive coding, thematic analysis (qualitative data) as well as descriptive analysis and t-tests (quantitative data) were performed. RESULTS: Both groups had similar energy and macronutrient consumption. Those in the WLM group reported higher levels of exercise and scored higher on several dimensions of eating disorders. Four themes - 'food choices,' 'quantities and portion control,' 'physical activity', and 'burden' - emerged from the qualitative data. Both groups used similar weight maintenance strategies, but those in the WLM group experienced a higher burden, expressing effortful control which contrasted with the control group's confidence in their internal cues. CONCLUSION: Our results show an additional burden related with maintaining weight loss compared to keeping a stable normal weight. They provide evidence to devise interventions that will address the difficulty of regulating intake.

RÉSUMÉ

Background: Dysfunctional cognitions regarding weight and shape and their implications for self-esteem are considered core features of anorexia nervosa and bulimia nervosa. However, they have also been associated with the severity of binge eating disorder (BED). Therefore, they should be screened with appropriate instruments to tailor treatment to individual patient needs. The Mizes Anorectic Cognitions-Revised (MAC-R) is a self-report questionnaire that lists dysfunctional cognitions related to three hypothesized core beliefs typical of the psychopathology of eating disorders: weight and eating as the basis of approval from others; the belief that rigid self-control is fundamental to self-worth; and the rigidity of weight- and eating-regulation efforts. Objectives: The goal of the study was to confirm the factor structure and to assess the validity of the MAC-R among a sample that met full-threshold and subthreshold criteria for BED. Methods: We used data of women meeting full-threshold (n = 94) and subthreshold (n = 22) criteria for BED to conduct confirmatory factor analyses and to compute Spearman's correlations, in order to assess factorial, convergent, and discriminant validity. Results: Two models having a structure of three factors with or without a total score proved to be acceptable. The MAC-R total score was correlated with questionnaires assessing dimensions related to eating disorder psychopathology, adding to the validity of the questionnaire. Conclusion: These results were similar to those found in studies on the psychometric properties of the MAC among samples with anorexia nervosa or bulimia nervosa, encouraging the use of the MAC-R as a research or clinical tool in order to further document the core beliefs underlying BED.

RÉSUMÉ

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.

RÉSUMÉ

Self-weighing seems to have a primary role in weight-loss maintenance. The use of this strategy may help correct even slight weight regain and contribute to long-term weight stability. However, self-weighing has also been associated with negative psychological health consequences in specific subgroups. This study aimed to explore the use and the behavioral and psychological consequences of self-weighing in a group of weight-loss maintainers (WLoMs). We chose a qualitative design to conduct this investigation. Eighteen WLoMs were interviewed and compared to a matched comparison group of 18 participants with a lifelong normal stable weight (NSW). Analyses showed that most WLoMs needed regular self-weighing to be aware of their weight. The weight displayed on the scale helped WLoMs sustain the continuous efforts needed to maintain weight loss and also at times triggered corrective actions that were sometimes drastic. Weight changes generated both negative and positive affect among WLoMs, who could experience anxiety because of self-weighing or have their self-esteem impaired in the case of weight gain. In comparison, the NSW group rarely used self-weighing. They relied on a conscious way of living to control their weight and needed fewer strategies. NSW participants simply went back to their routine when they felt a slight increase in their weight, without experiencing consequences on their mood or self-esteem. Regular self-weighing as a component of weight-loss maintenance should be encouraged to help WLoMs regulate their food and physical activity, provided that potential consequences on psychological well-being, including self-esteem, are screened and addressed when needed.

RÉSUMÉ

Eating behaviors are key when considering overweight or obesity management. Many issues varying in severity can interfere with the treatment. This article provides a semi-structured interview to address the determinants of food intake--hunger food craving--problematic eating behaviors--snacking, emotional eating--and eating disorders particularly related to overweight. Convenient for healthcare practitioners, this instrument comes with an interview guide to standardize its use. The relatively complete picture of the patient's eating behavior resulting from this assessment contributes to the treatment proposal.

RÉSUMÉ

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.

RÉSUMÉ

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.

RÉSUMÉ

Very restrictive weight-loss diets are still recommended by a number of physicians although their negative impact has been widely documented. Considering the complexity of obesity as a chronic disease, general practitioners' role in the assessment and follow-up of obese patients is crucial. In particular, they should set realistic guidelines-based goals, in coordination with the health care network. Our pilot study in one region of Switzerland showed a lack of coherence between guidelines and clinical management of obesity. Improved coordination and education of all health care professionals in this field could increase therapeutic efficacy and solve some of the ethical issues raised by inadequate prescriptions.

RÉSUMÉ

BACKGROUND AND OBJECTIVE: Long-term data on patients with obesity outcome after bariatric surgery are lacking. The goal was to document dietary and anthropometric changes more than 5 years after surgery, as well as patients' eating behavior, psychological state, and quality of life. METHODS: A cohort of 80 women (mean age 40+/-10 years) who underwent a Roux-en-Y gastric bypass between 1997 and 2002 were followed in a Swiss University Hospital for an average of 8+/-1.2 years. The primary outcome was successful weight loss defined as excess weight loss >or=50%. Body composition was measured by bioelectrical analysis, and diet was assessed via a food diary. Eating disorders, psychological factors, and quality of life were evaluated by questionnaires. Patients' perceptions of difficulties and benefits were explored using semistructured interviewing. Results at baseline and last visit were compared using paired t test. Cofactors' means were compared between successful and unsuccessful patients with Student t tests and logistic regression. RESULTS: Average weight loss 8 years after surgery was 30.7+/-13.8 kg. Excess weight loss >or=50% was observed for 47 patients (59%). Between baseline and last visit, relative proportions of fat mass/total body weight decreased, and fat-free mass/total body weight increased. Mean energy intake was 2,355+/-775 kcal at baseline and 1,680+/-506 kcal at last visit, with 42% of energy from carbohydrates, 39% of energy from fats, and 19% of energy from protein (0.8 g/kg). At last visit, 41 patients (51%) described episodes of binge eating or night eating syndrome. Factors associated with excess weight loss >or=50% were: younger age at operation, greater number of psychological consultations before the operation, and higher scores on ineffectiveness and social insecurity scales at baseline. CONCLUSIONS: More than half of the patients achieved successful weight loss, but disordered eating behavior was frequent. Periodic follow-up screenings and interdisciplinary care are advised. The definition of successful outcome should take into account problematic eating behaviors.

RÉSUMÉ

The aging of the population and the rising prevalence of chronic diseases mandate improved collaboration among different health professionals. Interprofessional training is one way to improve it, because it encourages health professionals to learn with, from and about one another and respects the integrity and contribution of each profession. Few medical or health professional schools develop such dimensions in their curricula, while postgraduate and continuous training seldom offer such opportunities. Institutional and political commitment may significantly contribute to the development of such dimensions in medical and other health profession education. Having a same mission, sharing responsibility for the team success, defining clear member roles and task, and communicating on a routine basis represent other key factors of success.

RÉSUMÉ

OBJECTIVES: To conduct an assessment of perceived dietary changes and problems by African asylum seekers, in order to develop appropriate nutritional education interventions. METHODS: A cross-sectional qualitative study among a convenience sample. Analysis compared and contrasted reported dietary changes and migration-related difficulties. RESULTS: Nineteen interviews were analysed. After migration, main dietary changes were the decrease in different fruits and vegetables consumed weekly from 10 to 2 and 17 to 10 respectively. The number of respondents drinking sweetened beverages more than 3 times a week increased from 3 to 18. Reasons for changes were related to prices, taste, choice and accessibility. CONCLUSION: These dietary changes may have serious health consequences. Future remedial interventions based on suggestions of the respondents could easily be implemented.

RÉSUMÉ

In order to study nutrient intake of amateur runners during a mountain marathon, compliance with recommendations, and association with performance, an intake of 42 participants in a Swiss mountain marathon was assessed by direct observation. Data on demographics, dietary preparation and race experience were obtained by questionnaires. Anthropometrical measures were performed before and after the race. Mean hourly intakes (SD) of fluid, carbohydrate, energy and sodium were 545 (158) ml, 31 (14) g, 141 (63) kcal [or 590 (264) kJ], and 150 (203) mg respectively. A third of the runners drank 600 ml h(-1) or more, 52% consumed less than 30 g h(-1 )carbohydrates, 95% consumed less than 500 mg h(-1) sodium. Mean weight loss was 4 (1.5) kg; 30 runners (71%) lost over 3% body mass. Mean running time was 7 h 3 min (1 h 17 min). Most participants failed to meet nutritional recommendations. None were at risk of overhydration. Body composition and race experience were correlated with performance, but not nutrient intake. Because experienced runners are well trained, fitter, and know better their personal needs during such a race, it is difficult to disentangle these associations. As causal relationship cannot be proven with this cross-sectional design, non-compliance with intake recommendations requires additional experimental research on the impact of nutrient intake on field performance.

RÉSUMÉ

In 1999 at an outpatient dietetic consultation in Geneva, Switzerland, 20% of the patients were refugees. Most were from the Former Yugoslavia. The main goal of dietary counseling was to decrease their fat consumption. As one-on-one counseling was unsuccessful, a pilot intervention was developed to explore the potential of participatory workshops for identifying and implementing appropriate behaviors. Four series of three workshops were held. Participants identified and practiced ways to reduce fat consumption. Knowledge skills were measured on completion of the workshops and 6 months later. Oil was highly valued in participants' representation of health. However, average reduction of oil per recipe was 58%, or 35 ml (95% CI: 15-55). The application of oil-sparing techniques increased nine-fold. Such an approach may be an alternative to one-on-one dietary counseling where this is ineffective. Next steps should include a trial to determine the impact of new skills on actual fat consumption.
