BackgroundEating disorders (ED) and disordered eating (DE) among male elite athletes share some of the characteristics seen in female elite athletes and the population, but also exhibit some key differences.ObjectiveScoping review of ED and DE in male elite athletes.MethodsIn May 2020, a comprehensive systematic literature search was conducted for DE and ED in male elite athletes.ResultsWe identified 80 studies which included 47 uncontrolled, 14 controlled studies, one interventional trial and 18 reviews.DiscussionThere was a wide range of definitions of DE and a high level of heterogeneity regarding competitive level, age and sport type. In adult male elite athletes, ED prevalence rates up to 32.5% were found, higher than in the general population. Prevalence was not higher in young/adolescent male elite athletes. The most frequently associated factor was competing in weight-sensitive sports. Male elite athletes tended to exhibit less body dissatisfaction than controls and were not always associated with DE. There were no studies looking at the prognosis or reporting an evidence-based approach for the management of DE in male elite athletes.ConclusionExisting literature indicates high prevalence of DE and ED in male elite athletes, with a wide range of aetiopathogenesis. There is a need for longitudinal studies to characterise the pathology and long-term outcomes, as well as develop standardised tools for assessment and treatments.
The PKB-7 scale is a reliable and a valid Rasch-based instrument in Swiss citizens aged between 18 and 80 years for measuring the practical knowledge about balanced meals based on current dietary guidelines. This brief and easy-to-use scale is intended for application in both research and practice.
Treatment guidelines recommend home treatment (HT) as an effective alternative to inpatient treatment for individuals with severe, acute mental illness (SAMI). Nevertheless, HT is largely unfamiliar in German-speaking countries. Here we examined the utilization and effectiveness of HT services newly implemented in a large hospital setting in Switzerland. We used a naturalistic observational study design including patients (n = 201, 18–65 years, 65.7% females) with SAMI who received HT between June 2016 and December 2017. HT patients were compared with a crude inpatient sample (n = 1078) and a matched inpatient sample (n = 201). Propensity-score matching was used to control for personal characteristics. Treatment outcomes were compared between HT patients and the matched inpatients based on routinely obtained medical data. The results showed that the HT sample consisted of more females (+21%), older (+4 years), and better educated (+10%) patients with more affective disorders (+13%) and less substance use disorders (−15%) as compared with the crude inpatient sample. The severity of symptoms was the same. After matching, there were no significant differences in the proportion of readmissions (36%), the duration until readmission and scores of the Health of the Nation Outcome Scales (HoNOS). The treatment duration of HT patients was significantly longer and, post-treatment, scores on the Global Assessment of Functioning scale (GAF) were significantly better. We conclude that HT is an effective treatment option for patients with SAMI also in Switzerland concerning the reduction of hospital days, the improvement of symptoms and functioning and readmission rates. HT cannot fully replace hospital admissions in all cases and HT may be beneficial for particular groups of patients (e.g., females and individuals with affective disorders). The study further shows the potential value of propensity-score matching in health care service research.
Background: Social inclusion is essential for an adequate rehabilitation process for people with serious mental illness (SMI). Various supported housing settings aim to promote housing competencies and social inclusion in service users. Nevertheless, there is a strong preference in service users for independent living. We aim to evaluate the effectiveness and efficiency of Independent Housing and Support (IHS) compared to institutionalised residential care settings and other treatment as usual conditions (RCS/TAU) in two cities in Switzerland. Methods: This is a prospective multi-centre, four-arm, non-inferiority cohort study investigating the effectiveness and efficiency of IHS and RCS/TAU for people with SMI. Effectiveness will be measured by a standardised measure of social inclusion as primary outcome as well as by measures of functioning and well-being. Efficiency will be analysed on the basis of service usage and costs associated with the different housing settings. Participants will be consecutively recruited and subsequently enrolled between April 2019 and December 2020 and assessed at baseline and after six, twelve and after 24 months. At one study site, 56 participants will be randomly assigned to one of the conditions; the other study site will be conducted as an observational study investigating 112 admitted participants. Discussion: While the UN Convention of the Rights of People with Disabilities aims to promote the opportunity to choose one's place of residence, the limited supply of alternative forms of housing does not guarantee genuine freedom of choice. Increased diversification and flexibility of housing support is essential. If IHS shows noninferiority in terms of their effectiveness and efficiency, users should be allowed to choose their kind of housing support.
Little is known about laypeople's practical understanding of a healthy diet, although this is important to successfully promote healthy eating. The present study is the first to experimentally examine how consumers define healthy and balanced food choices for an entire day compared with normal choices and compared with dietary guidelines. We used an extensive fake food buffet (FFB) with 179 foods commonly consumed in the Swiss diet. The FFB is a validated method to investigate food choice behaviour in a well-controlled laboratory setting. People from the general population in Switzerland (n 187; 51·9 % females), aged between 18 and 65 years, were randomly assigned to one of two conditions. In the control group, the participants were instructed to serve themselves foods they would eat on a normal day, whereas in the 'healthy' group they were instructed to choose foods representing a healthy diet. Participants chose significantly more healthy foods, with 4·5 g more dietary fibre, 2 % more protein and 2 % less SFA in the 'healthy' group compared with the control group. However, in both experimental conditions, participants served themselves foods containing twice as much sugar and salt than recommended by dietary guidelines. The results suggest that laypeople lack knowledge about the recommended portion sizes and the amounts of critical nutrients in processed food, which has important implications for communicating dietary guidelines. Furthermore, the energy of the food served was substantially correlated with the energy needs of the participants, demonstrating the potential of the fake food buffet method. For effective promotion of healthy eating among the general population, more insights about people's understanding of healthy food choices and how they translate their knowledge into practice are needed. Although consumers are surrounded by dietary information from various sources such as television, the Internet, food labels and health professionals, which sometimes provide conflicting messages, laypeople's perception about healthy eating seems to be strongly influenced by national dietary guidelines (1) . For instance, fruits and vegetables are perceived as healthy, whereas consumers usually associate foods containing high amounts of fat, sugar and salt with unhealthy eating (1) . Although consumers have some ideas about the healthiness of specific foods, they also have conceptions about production and preparation methods, as well as knowledge about the concepts of balance, variety and moderation, as suggested by dietary guidelines (1)(2)(3) .However, in Switzerland, adherence to dietary recommendations is low for most food categories and has not significantly improved over the past decade (4,5) . A healthy diet is correlated with higher education and a healthier overall lifestyle (6) , and adherence to dietary guidelines has been associated with reduced all-cause mortality (7,8) . Thus, further efforts are required to foster healthy eating. However, to set the right priorities among the large number of...
Background The social environment might play an important role in explaining people's physical activity (PA) behavior. However, little is known regarding whether personal networks differ between physically active and physically inactive people. This study aimed to examine the relationship between personal network characteristics and adults' physical (in)activity. Methods An egocentric social network study was conducted in a random sample in Switzerland ( n = 529, mean age of 53 years, 54% females). Individual and personal network measures were compared between regular exercisers and non-exercisers. The extent of these factors' association with PA levels was also examined. Results Non-exercisers ( n = 183) had 70% non-exercising individuals in their personal networks, indicating homogeneity, whereas regular exercisers ( n = 346) had 57% regularly exercising individuals in their networks, meaning more heterogeneous personal networks. Additionally, having more regular exercisers in personal networks was associated with higher PA levels, over and above individual factors. Respondents with an entirely active personal network reported, on average, 1 day of PA more per week than respondents who had a completely inactive personal network. Other personal network characteristics, such as network size or gender composition, were not associated with PA. Conclusion Non-exercisers seem to be clustered in inactive networks that provide fewer opportunities and resources, as well as less social support, for PA. To effectively promote PA, both individuals and personal networks need to be addressed, particularly the networks of inactive people (e.g., by promoting group activities).
