The Trans-Iron Galactic Element Recorder (TIGER) family of instruments is optimized to measure the relative abundances of the rare, ultra-heavy galactic cosmic rays (UHGCRs) with atomic number (Z) Z ≥ 30. Observing the UHGCRs places a premium on exposure that the balloon-borne SuperTIGER achieved with a large area detector (5.6 m2) and two Antarctic flights totaling 87 days, while the smaller (∼1 m2) TIGER for the International Space Station (TIGERISS) aims to achieve this with a longer observation time from one to several years. SuperTIGER uses a combination of scintillator and Cherenkov detectors to determine charge and energy. TIGERISS will use silicon strip detectors (SSDs) instead of scintillators, with improved charge resolution, signal linearity, and dynamic range. Extended single-element resolution UHGCR measurements through 82Pb will cover elements produced in s-process and r-process neutron capture nucleosynthesis, adding to the multi-messenger effort to determine the relative contributions of supernovae (SNe) and Neutron Star Merger (NSM) events to the r-process nucleosynthesis product content of the galaxy.

Primary cosmic-ray elemental spectra have been measured with the balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment since 2004. The third CREAM payload (CREAM-III) flew for 29 days during the 2007–2008 Antarctic season. Energies of incident particles above 1 TeV are measured with a calorimeter. Individual elements are clearly separated with a charge resolution of ∼0.12 e (in charge units) and ∼0.14 e for protons and helium nuclei, respectively, using two layers of silicon charge detectors. The measured proton and helium energy spectra at the top of the atmosphere are harder than other existing measurements at a few tens of GeV. The relative abundance of protons to helium nuclei is 9.53 ± 0.03 for the range of 1 TeV/n to 63 TeV/n. This ratio is considerably smaller than other measurements at a few tens of GeV/n. The spectra become softer above ∼20 TeV. However, our statistical uncertainties are large at these energies and more data are needed. [ABSTRACT FROM AUTHOR]

Weight stigma is a social justice issue that can lead to weight-based discrimination and mistreatment. In pregnancy, emerging evidence has highlighted that weight stigma predominantly affects individuals who have larger bodies and is associated with postpartum depression and avoidance of healthcare. Racial and ethnic background will influence perceptions of, and responses to, weight stigma and therefore it is necessary to ensure diverse voices are represented in our understanding of weight stigma. Semi-structured interviews were conducted with ten women who were within one year postpartum; nine identified as Black or African American and one as Hawaiian. Thematic analysis led to identification of three themes: (1) sources of weight stigma and their response to it, (2) support systems to overcome weight stigma, and (3) intersectional experiences. Women reported that sources of weight stigma included unsolicited comments made about their weight often coming from strangers or healthcare professionals that resulted in emotional distress. Support systems identified were family members and partners who encouraged them to not focus on negative remarks made about weight. Intersectional accounts included comparing their bodies to White women, suggesting that they may carry their weight differently. Women shared that, although they felt immense pressure to lose weight quickly postpartum, motherhood and childcare was their utmost priority. These findings inform further prospective examination of the implications of weight stigma in pregnancy among diverse populations, as well as inform inclusive public health strategies to mitigate weight stigma., Competing Interests: Declarations.

Background: As a rare endocrine disorder, Cushing's Syndrome (Cushing's) is characterized by numerous symptoms and a non-specific presentation, leading to a delay to diagnosis for patients with this disease. To date, research examining the lived experiences of patients with Cushing's in healthcare is absent in the literature. This preliminary inquiry into the healthcare experiences of women with Cushing's aimed to examine the utility of this line of inquiry to support the patient centered care of individuals with Cushing's., Methods: Seven women from across Canada with endogenous Cushing's participated in the study. Semi-structured interviews were conducted examining participants' healthcare and body-related experiences with Cushing's. Results pertaining to healthcare experiences were analyzed for the current study using reflexive thematic analysis., Results: Four themes emerged whereby women with Cushing's experienced (1) a lack of patient centered care, characterized by provider miscommunication and medical gaslighting; (2) a misunderstanding of their symptoms as related to weight gain; (3) weight stigma in healthcare encounters; and (4) a shift in their quality of care following diagnosis., Conclusions: The results highlight the importance of patient centered care as well as the negative impact of commonly reported barriers to patient centered care. Cushing's specific barriers to patient centered care may include weight stigma as well as the rare incidence of Cushing's. Further research is needed to better understand the healthcare experiences of people with Cushing's in Canada., (© 2024. The Author(s).)

Objectification theory has been instrumental in better understanding risk for eating disorders, depression, and sexual dysfunction, with self-objectification and body shame as serial mediators leading to these outcomes. Although originally proposed to explain these mental health outcomes in heterosexual women, researchers have extended objectification theory to individuals of various ages, racial identities, and sexual and gender identities. We conducted a systematic literature review of empirical peer-reviewed published research examining the relationship between the constructs of self-objectification, body dissatisfaction, and body shame in adult, youth, and LGBTQ+ samples. Our search yielded 5200 results, of which 318 met inclusion criteria. Of the papers included in this review, 26 reported correlations with sexual and gender diverse samples, 43 reported correlations with youth samples, and 249 reported correlations with samples of general adults (non-sexual or gender minorities). The meta-analyses yielded significant, moderate, positive correlations between body dissatisfaction and self-objectification, and between body shame and self-objectification, for each of the sub-samples. The majority of samples were predominantly White and cisgender female, suggesting the need for additional research examining these constructs among racial and gender minority populations. Overall, the results of this review highlight the unique contributions of body shame and body dissatisfaction to self-objectifying behaviors, and identify the moderating role of race and gender in these interrelations., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 Elsevier Ltd.

Background: Since the first papers focused on internalized weight stigma were published in the mid 2000's, the literature has grown into a robust field that complements existing knowledge on weight stigma. Recently, researchers have documented the need for increased conceptual and measurement clarity, to distinguish internalized weight stigma from body dissatisfaction. Although several systematic reviews have been conducted on portions of the internalized weight stigma literature, no review to date has been conducted examining the entirety of the literature., Objective: The aim of this research was to conduct a systematic scoping review and synthesis of research on internalized weight stigma. Specifically, we sought to examine the broad scope of the literature, terms used to refer to internalized weight stigma, how internalized weight stigma is defined, sample characteristics, and weight-based framings of internalized weight stigma research., Methods: We conducted a single-concept search across six databases (EMBASE, Medline, PsychINFO, PubMed, SCOPUS, and Web of Science) of peer-reviewed papers published in English on internalized weight stigma. Data were extracted for article authors, year published, journal name and type, general article topic(s), study design, study location, sample characteristics, variables measured, paper framing, term used to describe internalized weight stigma, and definition of internalized weight stigma., Results: Of the 931 unique records screened, 376 were identified for inclusion in the scoping review. The majority of internalized weight stigma research is characterized by cross-sectional methods, has been conducted in the US, and has utilized samples of higher weight white women. Further, 40 unique terms were used across the literature to refer to internalized weight stigma, and 19 different components of definitions of internalized weight stigma were identified. The literature is also characterized by a focus on understanding the association between internalized weight stigma and health outcomes with an emphasis on obesity., Conclusions: This scoping review confirms a lack of concept clarity of internalized weight stigma, in part influenced by an inconsistency in definitions of internalized weight stigma across the literature. Considerations are provided for steps to enhance conceptual and measurement clarity. Given the obesity focused framing of much of the research on internalized weight stigma, considerations are also provided for reducing weight-centric approaches to research. In the early 2000's, researchers began to pay more attention to the potential health impacts of believing societal stereotypes, negative attitudes, and beliefs about higher weight people. When these stereotypes, negative attitudes, and beliefs are directed towards the self, it can have significant consequences for an individual's perceptions of self. This research collected and summarized all existing research published in English on internalized weight stigma. Our results highlighted that researchers do not use consistent terminology to refer to internalized weight stigma and that they do not have a consistent definition of internalized weight stigma. Further, a large proportion of the research is focused on obesity or weight loss, which may unintentionally perpetuate weight stigma in scientific research. We provide several recommendations for researchers to address these challenges in future research on internalized weight stigma as well as recommendations to address other identified gaps in the existing literature., (© 2024.

Background: The words used to refer to weight and individuals with large bodies can be used to reinforce weight stigma. Given that most previous research has examined preferred terminology within homogenous groups, this research sought to examine terminology preferences across populations., Methods: This paper reports on data gathered with the general public, family physicians, and obesity researchers/practitioners. Participants were asked about the words they commonly: (1) used to refer to people with large bodies (general public); (2) heard in their professional contexts (physicians and obesity specialists); and (3) perceived to be the most socially or professionally acceptable (all samples)., Results: Similarities and differences were evident between samples, especially related to weight-related clinical terms, the word fat, and behavioral stereotypes., Conclusion: The results provide some clarity into the differences between populations and highlight the need to incorporate use of strategies that may move beyond person-first language to humanize research and clinical practice with people with large bodies.

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., (© 2023 The Authors.

The fear of fat, or fear of gaining weight, is conceptually related to both weight stigma and eating disorders. Since sociocultural pressures related to the thin ideal are important to examine within sociocultural models of body image, the Sociocultural Influences on Fear of Fat (SI-FAT) was created and validated on a sample of predominantly White college women. The purpose of this study was to examine the factor structure of the SI-FAT in a sample of racially and ethnically diverse college women, given potential differences in experiences of fear of fat and the need to measure sociocultural pressures related to fear of fat in multiple groups. A sample of college women (72.8% Hispanic/Latina, 14.85% Black, and 12.35% White) completed the SI-FAT as well as measures of weight stigma and body image. Results suggested that the factor structure of the SI-FAT were consistent across racial and ethnic groups. These findings indicate that the SI-FAT is appropriate for use among racially and ethnically diverse samples of young women. Directions for future research, including examining differences between sociocultural pressures related to weight gain and self-reported fear of fat are discussed., Competing Interests: Declaration of Competing Interest On behalf of the research team, I (SN) can confirm that we have no competing interests or conflicts of interest to disclose.

Though anthropometric measurement (AM) frequently occurs in school settings, it is not without risks to child wellbeing. The aim of this scoping review was to examine how AM in school settings takes place and is reported on to make recommendations on best practices. We identified and extracted data from 440 studies published since 2005 that conducted AM in school (pre-school through secondary/high school) settings. Privacy and sensitivity of AM were unclear in over 90% of studies. Thirty-one studies (7.0%) reported protecting student privacy, while nine (2.0%) reported public measurement. Only five studies reported sensitivity regarding AM (1.1%). Exactly who conducted AM was not specified in 201 studies (45.7%). Sixty-nine studies did not provide a weight status criteria citation (19.2%), and 10 used an incorrect citation (2.7%). In summary, serious shortcomings in the reporting of how AM is conducted and by whom, along with details concerning weight status classification, are evident. There is considerable room for improvement regarding the reporting of key methodological details. We propose best practices for AM in school settings, which also double as conditions that should be met before AM takes place in school settings., (© 2023 The Authors.

Background: With ongoing gaps in obesity education delivery for health professions in Canada and around the world, a transformative shift is needed to address and mitigate weight bias and stigma, and foster evidence-based approaches to obesity assessment and care in the clinical setting. Obesity Canada has created evidence-based obesity competencies for medical education that can guide curriculum development, assessment and evaluation and be applied to health professionals' education programs in Canada and across the world., Methods: The Obesity Canada Education Action Team has seventeen members in health professions education and research along with students and patient experts. Through an iterative group consensus process using four guiding principles, key and enabling obesity competencies were created using the 2015 CanMEDS competency framework as its foundation. These principles included the representation of all CanMEDS Roles throughout the competencies, minimizing duplication with the original CanMEDS competencies, ensuring obesity focused content was informed by the 2020 Adult Obesity Clinical Practice Guidelines and the 2019 US Obesity Medication Education Collaborative Competencies, and emphasizing patient-focused language throughout., Results: A total of thirteen key competencies and thirty-seven enabling competencies make up the Canadian Obesity Education Competencies (COECs)., Conclusion: The COECs embed evidence-based approaches to obesity care into one of the most widely used competency-based frameworks in the world, CanMEDS. Crucially, these competencies outline how to address and mitigate the damaging effects of weight bias and stigma in educational and clinical settings. Next steps include the creation of milestones and nested Entrustable Professional Activities, a national report card on obesity education for undergraduate medical education in Canada, and Free Open Access Medication Education content, including podcasts and infographics, for easier adoption into curriculum around the world and across the health professions spectrum., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: The authors declare no conflict of interest.

Background: Obesity is a prevalent chronic disease in Canada. Individuals living with obesity frequently interact with medical professionals who must be prepared to provide evidence-based and person-centred care options. The purpose of this scoping review was to summarize existing educational interventions on obesity in Canada for current and prospective medical professionals and to identify key future directions for practice and research., Methods: A scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. The search strategy was conducted using Medline (via PubMed), Embase, Eric, CBCA, Proquest Education, and Proquest Theses. The inclusion criteria included delivery of an educational intervention on obesity for current medical professionals, medical undergraduate trainees, or residents administered in Canada. Data were extracted from the included studies to thematically summarize the intervention content, and main outcomes assessed. Future directions for research and practice were identified., Results: Eight studies met the inclusion criteria. The interventions ranged in terms of the mode of delivery, including interactive in-person workshops and seminars, online learning modules, webinars, and videos. The main outcomes assessed were attitudes towards patients living with obesity, self-efficacy for having sensitive obesity-related discussions, skills to assess obesity and provision of management options. All studies reported improvements in the outcomes. Future directions identified were the need to develop standardized obesity competencies for inclusion across medical education programs, further research on effective pedagogical approaches to integrating content into existing curricula and the need for broader awareness and assessment of the quality of obesity education resources., Conclusion: Although there have been few obesity-specific educational interventions for current and prospective medical professionals in Canada, existing evidence shows positive learning outcomes. These findings advocate for continued investment in the development of obesity medical training and educational interventions., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Nicole Pearce is an employee of Obesity Canada.

Objective: Body dissatisfaction in pregnancy has been associated with negative psychological maternal outcomes, including increased risk of postpartum depression. This study aimed to explore weight-related factors that influence body dissatisfaction in pregnancy, including gestational weight gain (GWG), weight stigma, obesity, and weight loss attempts before pregnancy., Design: Secondary analysis of a larger cross-sectional study., Setting: Online survey administered via Qualtrics., Participants: ≥12 weeks pregnant, ≥18 years of age, having a singleton pregnancy and residing in Canada., Measurements and Findings: A battery of questionnaires were completed, including the Body Image in Pregnancy Scale (BIPS) sub-scale. The BIPS scores were compared based on experiences of weight stigma in pregnancy, perception towards their GWG, weight loss attempts before pregnancy, obesity, and GWG category classified as excessive or not referring to Institute of Medicine (2009) guidelines. Significant differences were entered into a linear regression model with BIPS scores as the dependent variable. Significance was accepted as p<0.05. A total of 182 participants completed the survey. There were no differences in BIPS scores based on GWG category (p = 0.160), or obesity (p = 0.230). Poorer BIPS scores were reported by those who felt they had gained 'too much' pregnancy weight than 'appropriate' (p<0.001), and among those who were trying to lose weight before pregnancy compared to those who were not (p = 0.002). Poorer BIPS scores were also reported by individuals who indicated they had experienced weight stigma during pregnancy compared to those who had not (p<0.001). Regression results showed that significant variables were perceptions towards GWG (p = 0.003) and experiencing weight stigma in pregnancy (p = 0.011)., Key Conclusions and Implications for Practice: Perceptions towards GWG and experiencing weight stigma can influence body dissatisfaction in pregnancy. Given the detrimental physical and psychological consequences of body dissatisfaction, effective strategies to reduce prenatal weight stigma are needed, such as training maternal healthcare providers to offer sensitive preconception and prenatal weight counselling., Competing Interests: Declaration of Competing Interests None declared., (Copyright © 2023.

Background: Recent research has shown that pregnant individuals experience weight stigma throughout gestation, including negative comments and judgement associated with gestational weight gain (GWG). Weight bias internalization (WBI) is often a result of exposure to weight stigma and is detrimental to biopsychological health outcomes. The purpose of this study was to explore WBI in pregnancy and compare scores based on maternal weight-related factors including pre-pregnancy body mass index (BMI), obesity diagnosis and excessive GWG., Methods: Pregnant individuals in Canada and USA completed a modified version of the Adult Weight Bias Internalization Scale. Self-reported pre-pregnancy height and weight were collected to calculate and classify pre-pregnancy BMI. Current weight was also reported to calculate GWG, which was then classified as excessive or not based on Institute of Medicine (2009) guidelines. Participants indicated if they were diagnosed with obesity by a healthcare provider. Inferential analyses were performed comparing WBI scores according to pre-pregnancy BMI, excessive GWG, and obesity diagnosis. Significance was accepted as p < 0.05 and effect sizes accompanied all analyses., Result: 336 pregnant individuals completed the survey, with an average WBI score of 3.9 ± 1.2. WBI was higher among those who had a pre-pregnancy BMI of obese than normal weight (p = 0.04, η 2  = 0.03), diagnosed with obesity than not diagnosed (p < 0.001, Cohen's d = 1.3), and gained excessively versus not (p < 0.001, Cohen's d = 1.2)., Conclusions: Pregnant individuals who have a higher BMI, obesity and gain excessively may experience WBI. Given that weight stigma frequently occurs in pregnancy, effective person-oriented strategies are needed to mitigate stigma and prevent and care for WBI., (© 2022. The Author(s).)

Both body dissatisfaction and internalized weight stigma have been identified as risk factors for many negative health outcomes for women, including depression and eating disorders. In addition to these contributions, these concepts have been found to overlap to various degrees in existing literature. We conducted a systematic review and meta-analysis on articles published prior to February 2022 to demonstrate the conceptual and measurement overlap between body dissatisfaction and internalized weight stigma as currently quantified. We identified 48 studies examining the interrelation between body dissatisfaction and internalized weight stigma in predominantly female samples. Stronger correlations between these two constructs, some bordering on multicollinearity, were prevalent in community samples compared to clinical samples and with some but not all the commonly used measures in the body image and weight stigma fields. Body mass index (BMI) moderated these relations such that individuals with higher self-reported BMI were more likely to report lower correlations between the constructs. This concept proliferation, stronger for individuals with lower BMIs and community samples, necessitates the need change how we conceptualize and measure body dissatisfaction and internalized weight stigma. To this end, we conducted study two to refine existing measures and lessen the degree of measurement overlap between internalized weight stigma and body dissatisfaction, particularly in community samples of women. We aimed to clarify the boundaries between these two concepts, ensuring measurement error is better accounted for. Female university students completed existing measures of body satisfaction and internalized weight stigma, which were analyzed using an exploratory followed by a confirmatory factor analysis. In our attempts to modify two existing measures of internalized weight stigma and body dissatisfaction, the majority of the internalized weight stigma items were retained. In contrast, most of the body dissatisfaction items either cross-loaded onto both factors or loaded on to the internalized weight stigma factor despite being intended for the body dissatisfaction factor, suggesting that the measurement issues identified in recent prior research may be due not only to the way we conceptualize and quantify weight stigma, but also the ways in which we quantify body dissatisfaction, across the existing corpus of body dissatisfaction scales., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Saunders, Nutter and Russell-Mayhew.)

Purpose: Overt restrictive feeding practices (ORFP), aimed at promoting weight loss or preventing weight gain for children, are often implemented by parents with good intentions. Despite findings that indicate unintended weight and behavioral outcomes little is known about how parental ORFP are experienced by those who are subjected to them. Thus, we explored retrospective accounts of meaning making related to experiences of such practices during childhood., Methods: Six young adult females who experienced ORFP were interviewed. Data were analyzed using constructivist grounded theory., Results: Participants retrospectively associated experiencing ORFP with a meaning making process that involves: (a) perceiving parental motivation for ORFP and receiving messages about weight, (b) internalizing parental messages about weight, and (c) viewing self-worth as contingent on weight., Conclusion: Preliminary findings suggest that parents may be reinforcing weight stigma in their children through ORFP. Results add evidence against the use of parental ORFP for childhood weight management., Level of Evidence: Level V, Descriptive study., (© 2020. Springer Nature Switzerland AG.)

Purpose: Weight stigma is pervasive and is associated with numerous physical and psychological health consequences, including decreased body satisfaction. Understanding of contributing factors to weight stigma remains limited, although researchers have consistently documented the connection between weight controllability beliefs and weight stigma. Sociocultural factors, including thin-ideal internalization and related social-cognitive correlates, are in the nascent stages of exploration to further our understanding of weight stigma., Methods: In this study, we tested an emerging sociocultural model of weight stigma, examining the influence of thin-ideal internalization and appearance-related comparisons on weight stigma, statistically controlling for weight controllability beliefs and accounting for thin-ideal environmental influences. Participants were 137 MTurk workers living in the United States., Results: We found that increased thin-ideal information was associated with thin-ideal internalization, which in turn was related to both upward and downward appearance-related comparison tendencies. These comparisons were then significantly related to weight stigma, controlling for weight controllability beliefs. There were significant indirect effects of both upward and downward appearance-related comparison tendencies on the relation between thin-ideal internalization and weight stigma., Conclusion: These results extend limited prior research examining the association between the thin-ideal and appearance-related comparisons with weight stigma, and contribute to a more nuanced understanding of this complex phenomenon., Level of Evidence: Level V, cross-sectional study.

Purpose: To conduct a systematic literature review of empirical peer-reviewed published studies on the prevalence of weight bias among students, pre-service, and in-service teachers and its impact on the educational experiences and health of students from kindergarten to postsecondary settings., Methods: Keywords were searched on three main concepts, (i) weight bias/stigma, (ii) obesity/overweight, and (iii) education, within eight databases. Our search yielded 8323 individual records, of which 45 studies satisfied our inclusion criteria., Results: Most studies were conducted in K-12 school settings (n = 41), were quantitative in design (n = 37), and used student samples (n = 18). Weight bias is prevalent in educational settings, among peers at school as well as pre-service and in-service teachers, and negatively impacts students' health and educational experiences., Conclusion: These results highlighted the impact of weight bias in creating inequity for students with obesity as well as several underexamined areas, such as weight bias in postsecondary settings and attitudes among teachers and pre-service teachers. Innovative strategies to address weight bias in educational settings are needed.

Objectives: The aim of this study was to examine the attitudes of practicing Canadian family physicians about individuals with obesity, their healthcare treatment, and perceptions of obesity treatment in the public healthcare system., Method: A national sample of Canadian practicing family physicians (n = 400) completed the survey. Participants completed measures of explicit weight bias, attitudes towards treating patients with obesity, and perceptions that people with obesity increase demand on the public healthcare system., Results: Responses consistent with weight bias were not observed overall but were demonstrated in a sizeable minority of respondents. Many physicians also reported feeling frustrated with patients with obesity and agreed that people with obesity increase demand on the public healthcare system. Male physicians had more negative attitudes than females. More negative attitudes towards treating patients with obesity were associated with greater perceptions of them as a public health demand., Conclusion: Results suggest that negative attitudes towards patients with obesity exist among some family physicians in Canada. It remains to be determined if physicians develop weight bias partly because they blame individuals for their obesity and its increased demand on the Canadian public healthcare system. More research is needed to better understand causes and consequences of weight bias among health professionals and make efforts towards its reduction in healthcare., (© 2019 The Author(s) Published by S. Karger AG, Basel.)

Background/objectives: Obesity has been declared a disease by the American and Canadian Medical Associations. Although these declarations sparked much debate as to the impact of framing obesity as a disease on weight bias, strong empirical research is needed to examine this impact. The current study examined the impact of framing obesity a disease on weight bias, focusing on moderating and mediating processes., Subjects/methods: A sample of 309 participants living in the United States or Canada was recruited from Crowdflower. Participants completed measures of demographics, ideology, general attitudes, and previous contact quality and quantity with people living with obesity. Participants then read one of three articles as part of an experimental manipulation framing obesity as a disease, obesity not as a disease, and a control article unrelated to obesity. Post-manipulation included measures of affect, disgust, empathy, blame, and weight bias., Results: Orthogonal contrasts were used to compare the obesity-disease condition to the obesity-not-disease condition and control condition. The manipulation had a direct effect on affect (emotions), such that affect toward individuals with obesity was more positive in the obesity-disease condition than the obesity-not-disease and control condition combined. Exploration of moderating effects revealed that both the belief in a just world and weight satisfaction moderated the relationship between the obesity-disease manipulation and blame for obesity. Two models of indirect effects on weight bias were also examined, which demonstrated that the obesity-disease manipulation predicted less weight bias through more positive affect (model 1) as well as less weight bias through decreased blame among individuals high in belief in a just world (model 2)., Conclusions: This study further highlights the complex effects of declaring obesity a disease, uncovering a new direction for future research into the role of affect as well as indirect effects of characterising obesity a disease on weight bias.

Innovative and coordinated strategies to address weight bias among health professionals are urgently needed. We conducted a systematic literature review of empirical peer-reviewed published studies to assess the impact of interventions designed to reduce weight bias in students or professionals in a health-related field. Combination sets of keywords based on three themes (1: weight bias/stigma; 2: obesity/overweight; 3: health professional) were searched within nine databases. Our search yielded 1447 individual records, of which 17 intervention studies satisfied the inclusion criteria. Most studies (n = 15) included medical, dietetic, health promotion, psychology and kinesiology students, while the minority included practicing health professionals (n = 2). Studies utilized various bias-reduction strategies. Many studies had methodological weaknesses, including short assessment periods, lack of randomization, lack of control group and small sample sizes. Although many studies reported changes in health professionals' beliefs and knowledge about obesity aetiology, evidence of effectiveness is poor, and long-term effects of intervention strategies on weight bias reduction remain unknown. The findings highlight the lack of experimental research to reduce weight bias among health professionals. Although changes in practice will likely require multiple strategies in various sectors, well-designed trials are needed to test the impact of interventions to decrease weight bias in healthcare settings., (© 2016 World Obesity.)

Weight bias is a form of stigma with detrimental effects on the health and wellness of individuals with large bodies. Researchers from various disciplines have recognized weight bias as an important topic for public health and for professional practice. To date, researchers from various areas have approached weight bias from independent perspectives and from differing theoretical orientations. In this paper, we examined the similarities and differences between three perspectives (i.e., weight-centric, non-weight-centric (health-centric), and health at every size) used to understand weight bias and approach weight bias research with regard to (a) language about people with large bodies, (b) theoretical position, (c) identified consequences of weight bias, and (d) identified influences on weight-based social inequity. We suggest that, despite differences, each perspective acknowledges the negative influences that position weight as being within individual control and the negative consequences of weight bias. We call for recognition and discussion of weight bias as a social justice issue in order to change the discourse and professional practices extended towards individuals with large bodies. We advocate for an emphasis on social justice as a uniting framework for interdisciplinary research on weight bias., Competing Interests: The authors declare that they have no competing interests.
