Abstract
Weight stigma is persistent across contexts and is associated with disordered eating cognitions and behaviors. This systematic review aimed to examine the existing literature that has explored the relationship between weight stigma and disordered eating cognitions and behaviors. We specifically examined three dimensions of weight stigma - experienced, anticipated, and internalized - and adopted an inclusive conceptualization of outcomes related to disordered eating (including constructs such as binge eating, body dissatisfaction, and other cognitions and behaviors such as dietary restraint, unhealthy weight control behaviors, and drive for thinness). We searched PubMed, Embase, CINAHL, Web of Science, Sociological Abstracts, and PsycINFO for English-language, peer-reviewed articles and dissertations with quantitative methodology published through October 2023. The search resulted in 242 articles meeting inclusion criteria. A narrative review found a consistent relationship between greater weight stigma and more disordered eating cognitions and behaviors. Methodological and theoretical limitations are discussed, as are critical avenues for future research and potential clinical implications stemming from this body of research. Given the widespread nature and impact of weight stigma on disordered eating, it is imperative that we intervene to address weight stigma at all levels, from the structural to the intrapersonal.

Abstract
Weight stigma, defined as pervasive misconceptions and stereotypes associated with higher body weight, is both a social determinant of health and a human rights issue. It is imperative to consider how weight stigma may be impeding health promotion efforts on a global scale. The World Obesity Federation (WOF) convened a global working group of practitioners, researchers, policymakers, youth advocates, and individuals with lived experience of obesity to consider the ways that global obesity narratives may contribute to weight stigma. Specifically, the working group focused on how overall obesity narratives, food and physical activity narratives, and scientific and public-facing language may contribute to weight stigma. The impact of weight stigma across the lifespan was also considered. Taking a global perspective, nine recommendations resulted from this work for global health research and health promotion efforts that can help to reduce harmful obesity narratives, both inside and outside health contexts.

Magallares, A, Recio, P, Jáuregui-Lobera, I, Benito de Valle, P, Irles, JA, Hymowitz, G
Eating behaviors. 2024;:101827
Abstract
Weight-related abuse is defined as verbal or physical maltreatment specific to one's weight. The Weight-Related Abuse Questionnaire (WRAQ) is an instrument specifically designed to measure weight-related abuse. The main goal of this research was to study the factor structure and measurement invariance of the Spanish version of the WRAQ in a non-clinical and a clinical sample. The clinical sample included 150 participants with obesity (60 % women) from the Hospital de Valme (Sevilla, Spain). The non-clinical sample included 301 students (79 % women) from the Spanish Open University (UNED). Scales to measure weight self-stigma and fear of gaining weight were used to analyze the convergent validity of the WRAQ. A confirmatory factor analysis showed that a two-factor model (verbal and physical abuse) was an acceptable fit for the data in both the clinical and non-clinical samples. Multigroup Confirmatory Factor Analysis revealed scalar measurement invariance by sample and gender. Cronbach's alpha coefficients and composite reliability for both samples were found to be good, with values ranging from 0.83 to 0.96. Fear of gaining weight was correlated to verbal (r = 0.36, p < .01) and physical (r = 0.12, p < .05) abuse, and weight self-stigma was also related to physical (r = 0.21, p < .01) and verbal (r = 0.41, p < .01) abuse. These results suggest that the WRAQ can be used in clinical and non-clinical samples to assess verbal and physical abuse in both men and women.

Hawley, N, Green, J, Ahlich, E, Hauff, C, Hermer, J, Skiba, MB, James, DL, Nash, SH
Cancer medicine. 2024;(3):e6882
Abstract
BACKGROUND Weight stigma has been defined as the social devaluation and denigration of individuals because of their weight. The purpose of this scoping systematic review was to assess and understand patient experiences with weight stigma in the cancer care setting. METHODS We conducted a systematic scoping review of studies examining shame, prejudice, bias, and stigma in relation to weight and cancer-related care using five databases: PubMed, CINAHL Plus Full Text (ProQuest), Cochrane Library, PsycINFO (EBSCO), and Scopus. Articles were uploaded into Covidence for de-duplication and screening. Included studies were peer reviewed, reported adult patient experiences in cancer-related care, and were published in English between October 2012 and February 2023. Study characteristics and key findings were abstracted and qualitatively synthesized. RESULTS Publications meeting inclusion criteria yielded five studies (n = 113 participants). Most focused on the experiences of women (n = 4) and cancers which predominantly impact women (i.e., breast, cervical, endometrial; n = 4). All stages of the cancer continuum were included with studies examining screening (n = 2), treatment (n = 1), and post-treatment survivorship (n = 2). Weight discrimination was discussed in four studies and weight-biased stereotypes were discussed in three studies. Experiences of weight bias internalization were reported in four studies. One study described an instance of implicit weight bias. CONCLUSIONS Limited studies examine patient experiences of weight stigma in cancer care; however, current evidence suggests that patients do experience weight stigma in cancer-related care. This review highlights critical gaps and a need for more research on the prevalence and impact of weight stigma in cancer screening and care.

Clinical practice guidelines for the management of overweight and obesity published internationally: A scoping review.
Gaskin, CJ, Cooper, K, Stephens, LD, Peeters, A, Salmon, J, Porter, J
Obesity reviews : an official journal of the International Association for the Study of Obesity. 2024;:e13700
Abstract
With the increasing prevalence of obesity placing additional demands on healthcare systems, many jurisdictions and professional bodies have developed clinical practice guidelines to support practitioners in the management of people with overweight and obesity. This scoping review aimed to identify key features of contemporary guidelines for the clinical management of overweight and obesity. Searches of MEDLINE, Guidelines International Network's international guidelines library, and other grey literature sources identified 38 guidelines of 18 countries and one region published since 2010. Guidelines were developed by committees (n = 36, 95%) that comprised knowledgeable experts (n = 36, 95%) and were multidisciplinary (n = 33, 87%), with limited consumer representation (n = 11, 29%). Guideline documentation incorporated review questions (n = 23, 61%), systematic reviews (n = 25, 66%), evidence grading systems (n = 33, 87%), processes for reaching consensus (n = 19, 50%), and guideline review details (n = 28, 74%). Treatment approaches included in most guidelines were nutrition and physical activity (n = 38, 100%), psychology (n = 37, 97%), pharmacotherapy (n = 32, 84%), and bariatric surgery (n = 31, 82%). Most guidelines targeted populations based on age (n = 30, 79%). Guidelines contained recommendations for pregnancy (n = 12, 32%), older adults (n = 9, 24%), and people with eating disorders (n = 8, 21%). Future guidelines would benefit from involvement of consumers including groups known to be at increased risk of overweight and obesity, targeted guidance for at risk groups, and consideration of weight bias and stigma.

Exposure to written content eliciting weight stigmatization: Neural responses in appetitive and food reward regions.
Anguah, KOB, Christ, SE
Obesity (Silver Spring, Md.). 2024;(1):80-90
Abstract
OBJECTIVE Neural activity in food reward- and appetite-related regions was examined in response to high-calorie (HC), low-calorie, and non-food pictures after exposure to written weight stigma (WS) content. Relationships with eating behavior (by Three-Factor Eating Questionnaire [TFEQ]), blood glucose, and subjective appetite were also explored. METHODS Adults with overweight and obesity were randomized to read either a WS (n = 20) or control (n = 20) article and subsequently underwent brain scans while they rated pleasantness of food pictures. Fasting glucose, TFEQ, stigma experiences, and appetite were measured before reading the article, appetite after reading, and glucose and appetite again after the scan. RESULTS A priori region of interest analyses revealed significant group differences in activation to HC > low-calorie food cues in the caudate and thalamus whereas exploratory whole-brain analyses suggested significant differences in regions including left insula, left thalamus, left inferior temporal gyrus, right lingual gyrus, and bilateral middle occipital gyrus and superior parietal lobule (p < 0.005 uncorrected, k ≥ 200 m3 ). No significant relationships were observed between the pattern of activation and TFEQ, glucose, or subjective appetite in the WS group. CONCLUSIONS Exposure to WS was associated with increased responsiveness to HC food content in the dorsal striatum and thalamus in individuals with overweight and obesity.

Brenton-Peters, JM, Consedine, NS, Cavadino, A, Roy, R, Ginsberg, KH, Serlachius, A
British journal of health psychology. 2024;(1):37-58
Abstract
INTRODUCTION Weight loss is hard to achieve and even harder to maintain. Engaging in effortful behavioural change to manage body weight can sometimes result in feelings of guilt and shame. Self-compassion, the tendency to find kindness for oneself in times of struggle, may facilitate coping with the unique challenges of weight management. This study assessed whether a remotely delivered self-compassion intervention improved weight management outcomes when delivered as a supplement to an existing digital behavioural weight management programme, Weight Watchers (WW). METHOD Using a mixed-method study design, 249 adults seeking to manage weight were randomized to either the WW programme or WW supplemented with the self-compassion for weight management intervention (SC4WM). Participants completed measures of self-compassion, eating behaviour, physical activity, body weight and emotional well-being along with potential moderators, including weight self-stigma, eating restraint, psychological coping and perceived stress at baseline, post-intervention (4 weeks) and follow-up (12 weeks). RESULTS There was no evidence that the SC4WM intervention had a significantly different effect than WW alone. Other than body weight, all outcomes improved over time in both groups. Self-compassion was slightly higher overall in the SC4WM group (p = .05), with this group reporting higher self-kindness at 4 weeks (p = .014) and lower self-judgement at 12 weeks (p = .023) compared to the control group. CONCLUSIONS Although the SC4WM intervention group did show a small increase in self-kindness and reduction in self-judgement, weight management outcomes were not improved over and above the existing WW programme. Recommendations for adapting the SC4WM intervention to improve efficacy to augment weight management outcomes are provided.

Addressing uncertainty about the role of structured lifestyle modification for metabolic surgery patients.
Murphy, E, Finucane, FM
Metabolism: clinical and experimental. 2024;:155739
Abstract
There is good evidence that structured lifestyle modification programmes improve health in patients with metabolic and cardiovascular disorders, but there is no specific evidence that they improve outcomes in patients undergoing metabolic or obesity surgery. Despite expert consensus guidelines stating this fact, some healthcare systems still compel patients to participate in a structured lifestyle modification programme prior to metabolic or obesity surgery. There is a well-established need for individualised multidisciplinary dietetic and physical activity care for metabolic and obesity surgery patients, and the benefits of intentional weight loss prior to surgery are well proven, but these are distinct from potentially harmful requirements for patients to undertake compulsory structured lifestyle programmes of fixed duration, frequency and intensity, which may delay surgery and reinforce obesity stigma. A critical step in rejuvenating metabolic surgery is to reframe patient participation in structured lifestyle modification programmes as an opportunity for education and empowerment, not as an indicator of motivation or suitability for metabolic surgery. Large, well-designed and adequately powered clinical trials are needed to address uncertainties in the evidence base for these programmes. Given genuine equipoise, they will need to determine whether "surgery plus lifestyle" is superior to "surgery plus placebo". Moreover, they will need to determine the cost-effectiveness of these programmes and identify some of the factors giving rise to the substantial heterogeneity in responses to structured lifestyle modification.

Reframing interventions for optimal child nutrition and childhood obesity: the importance of considering psychological factors.
Newson, L, Abayomi, J
The Proceedings of the Nutrition Society. 2024;:1-12
Abstract
This review aims to emphasise the impact of poor nutrition on children's health and psychological well-being, urging those involved in childhood obesity or nutrition services to broaden their intervention approach. Poor nutrition and childhood obesity affect physical and psychological health. The stress of living with obesity further impacts quality of life, well-being and self-esteem. Children living with obesity may experience adverse childhood events and stress, and young people are able to recall the impact of psychosocial issues such as experiencing stigma and discrimination. Food is often a coping mechanism for managing negative emotions, perpetuating cycles of emotional coping and unhealthy eating behaviours. UK guidelines recommend family-based, multi-component weight management interventions for children living with obesity. Interventions mainly target health behaviours and utilise behaviour change techniques attempting to directly improve diet and physical activity as behavioural outcomes. Whilst these interventions may show some improvements in psychological well-being, there is limited consideration or understanding of the underlying mechanisms of action which indirectly influence engagement and the sustainability of the behaviour change. Lack of attention and inclusion of psychosocial variables in intervention implementation may help explain the variable effectiveness reported across childhood obesity interventions. In conclusion, enhancing the effectiveness of childhood obesity interventions requires a broader approach that fully incorporates psychosocial factors. Those responsible for commissioning, designing and implementing these interventions should adopt a holistic approach that addresses psychological and emotional needs while incorporating underlying mechanisms of action. This shift in focus could result in more sustainable and comprehensive treatment for childhood obesity.
