Gewichtsstigmatisierung und gewichtsneutrale Interventionen in der Ernährungsberatung: Ein Scoping Review
摘要
The stigmatisation of overweight people is a problem, as negative attributions can have an impact on the physical and mental health of those affected, as well as on the success of dietary interventions. With increasing awareness of this issue, weight-centred interventions and the effectiveness of weight-normative approaches are being questioned. Weight-neutral approaches are also gaining popularity in nutritional counselling. The aim of this study is to present the current state of research on the effectiveness of weight-neutral nutritional interventions and the stigmatising attitudes of nutrition professionals.
MethodsFor the scoping review, the PubMed, Web of Science Core Collection and APA PsycInfo databases were searched for both topics. Studies from countries in the Global North, with adult study populations and a publication date after 2003 were included.
ResultsThe studies included in the review (n = 30) were mostly published after 2020 and conducted predominantly in the USA in white female study populations. Eight of the ten studies on stigmatising attitudes among nutrition professionals reveal weight-related prejudices, e.g. in four vignette-based studies in which overweight individuals are rated significantly more negatively. Studies on the effectiveness of weight-neutral dietary interventions (n = 20) show psychological improvements, such as a reduction in eating disorder symptoms, whereas there are no negative effects on physical parameters.
ConclusionThe results suggest that nutrition professionals have stigmatising attitudes that may affect the treatment of clients. Furthermore, it appears that weight-neutral approaches can offer advantages, especially in psychological aspects. There are still gaps in research in both areas; for example, there is a lack of reliable data from randomised controlled trials. Future studies should clarify which counselling strategies support health-promoting behavioural changes. In addition, the mechanisms of action of weight-neutral concepts should be systematically investigated.
