Research suggests that weight stigma is increasing and is associated with multiple negative health and psychological outcomes. Public health messaging presently emphasises weight gain as lack of personal control of diet and exercise, which contributes to the stigma and ignores the myriad of uncontrollable factors that also contribute to weight gain. One component of weight gain is food addiction, in which food is shown to be as rewarding to the brain as other addictive substances. It is currently unclear whether an explanation of the food addiction model (FAM) will affect weight stigma, and there is a need to understand the factors that contribute and reinforce weight stigmatisation. The aim of this study is to assess whether providing a FAM explanation for weight gain would impact expressions of weight stigma. Two experiments were done in which college students were randomly allocated to read a simulated article that focused on either food addiction or diet and exercise as contributing factors to obesity. The participants then completed a survey assessing their perception of obesity. This study found the FAM explanation resulted in a significantly lower weight stigma. Based on these results, the authors suggest current public health messaging that attributes obesity to lack of personal control needs to be changed as it exacerbates weight stigma.
Abstract
There is increasing scientific and public support for the notion that some foods may be addictive, and that poor weight control and obesity may, for some people, stem from having a food addiction. However, it remains unclear how a food addiction model (FAM) explanation for obesity and weight control will affect weight stigma. In two experiments (N = 530 and N = 690), we tested the effect of a food addiction explanation for obesity and weight control on weight stigma. In Experiment 1, participants who received a FAM explanation for weight control and obesity reported lower weight stigma scores (e.g., less dislike of 'fat people', and lower personal willpower blame) than those receiving an explanation emphasizing diet and exercise (F(4,525) = 7.675, p = 0.006; and F(4,525) = 5.393, p = 0.021, respectively). In Experiment 2, there was a significant group difference for the dislike of 'fat people' stigma measure (F(5,684) = 5.157, p = 0.006), but not for personal willpower weight stigma (F(5,684) = 0.217, p = 0.81). Participants receiving the diet and exercise explanation had greater dislike of 'fat people' than those in the FAM explanation and control group (p values < 0.05), with no difference between the FAM and control groups (p >0.05). The FAM explanation for weight control and obesity did not increase weight stigma and resulted in lower stigma than the diet and exercise explanation that attributes obesity to personal control. The results highlight the importance of health messaging about the causes of obesity and the need for communications that do not exacerbate weight stigma.

Obesity is a global health issue due to its association with many chronic diseases, including type 2 diabetes, cardiovascular disease and certain cancers. Stigmatisation and discrimination against people with obesity has increased over the past few decades. According to the “Theory of class” a person’s “habitus”, that is their general attitude, lifestyle and even body shape, can be seen as a metaphor for social status. The aim of this systematic review of 17 studies was to investigate whether socioeconomic status is associated with “weight bias”, that is stigmatising and discriminating attitudes towards people with obesity. 11 of the 17 studies found a significant association between educational attainment and/or income with stigmatising and/or discriminatory attitudes, but results were mixed, with some studies showing that people with higher education and/or income level were more likely to display stigmatising and/or discriminating attitudes, whilst other studies showed the opposite. The authors conclude that the findings have to be discussed in the cultural context, including cultural and governmental differences.
Abstract
OBJECTIVES Obesity is considered a global health issue, because of its health-related consequences and also because of its impact on social status as a result of stigma. This study aims to review the quantitative state of research regarding socioeconomic characteristics' influence on weight-related stigmatisation and discrimination. Based on Bourdieu's Theory of Class and his concept of 'habitus', it is assumed that people with a higher level of education and income show stronger negative attitudes towards people with obesity. METHOD A narrative systematic literature review was conducted in 2017 using PubMed, PsychINFO, Web of Science and the Cochrane Library. Seventeen studies that measured weight bias and either educational attainment or level of income were included in the analysis. RESULTS The results of the studies included were inconsistent: six of these studies were found to support the hypothesis, whereas two of the studies contradicted it. The remaining seven studies did not show any significant correlation between weight bias and either education or income. CONCLUSION In light of the inconsistent and heterogeneous results of the studies that report a significant association between weight bias and socioeconomic variables, the findings must be discussed concerning their cultural context, that is, cultural and governmental differences. Furthermore, educational attainment seems to be more likely to predict weight bias than income. The review revealed a lack of research when it came to examining the impact of socioeconomic capital on weight bias.

Plain language summary
Consumption of sugar-sweetened beverages is associated with increased body weight and poor nutrition and health outcomes, including Type 2 diabetes and coronary heart disease. The aim of this study was to test the hypothesis that the graphic warning promotes weight bias (Study 1) and is also viewed as stigmatizing by people with overweight and obesity (Study 2). Study 1 Participants were randomly allocated to one of two conditions: a warning label condition (n = 324) or a control condition (n = 357). Results indicate that participants who were presented with the graphic warning label were more likely to intend to purchase water (instead of the soda) than participants who were presented with the standard label. Study 2 Participants (n=561) were randomly assigned to one of two conditions – overweight or obese. Results show that the majority of participants rated the warning label as personally stigmatizing. Moreover, after being exposed to the label, the participants experienced worse mood. Authors conclude that it is important for policymakers to strike a balance between the benefits and costs of public health interventions.
Abstract
INTRODUCTION Public health interventions need to balance the benefits with any potential harms. One proposed intervention for reducing sugar-sweetened beverage consumption involves placing graphic warning labels on products and advertisements. A recent study found that a graphic warning label that contained negative imagery of obesity reduced purchases of sugar-sweetened beverages. However, these labels may also promote obesity stigma, which is concerning given that weight stigma is associated with harmful health consequences including weight gain and increased risk of mortality. METHODS In Study 1 (n = 681), participants viewed a standard soda label or the graphic warning label online and then completed measures of disgust and prejudice towards people with obesity. In Study 2 (n = 506), participants who identified as having overweight or obesity viewed the graphic warning label online before or after completing measures of mood and state self-esteem. RESULTS In Study 1, participants who had viewed the graphic warning label reported higher disgust and weight bias. In Study 2, the majority of participants perceived the warning label to be stigmatizing, and participants displayed worse mood and, through this, lower self-esteem after viewing the label. CONCLUSIONS Although the graphic warning label has been found to reduce sugary drink purchases, it also promotes obesity stigma and is perceived as stigmatizing by individuals with overweight and obesity. Given that weight stigma predicts harmful health and well-being consequences, the benefits of graphic warning labels need to be balanced against the potential costs.

Plain language summary
Weight stigma is defined as the social rejection and devaluation that accrues to those who do not comply with prevailing social norms of adequate body weight and shape. In this opinion-based study, authors discuss that: • Latest literature indicates that weight stigma can trigger physiological and behavioural changes linked to poor metabolic health and increased weight gain. • Healthcare is a setting in which weight stigma is particularly pervasive, with significant consequences for the health of higher-weight patients. This stigma has direct and observable consequences for the quality and nature of services provided to those with obesity. • Stigma may be an unintended consequence of anti-obesity efforts, undermining their intended effect. Moreover, focusing solely on obesity treatment runs the risk of missing other diagnoses. • The science of weight stigma crystallizes a key point for future success – to tackle the obesity ‘epidemic’ we must tackle the parallel epidemic of weight stigma. • Public service messages are needed to educate people about the stigma, discrimination, and challenges facing higher-weight individuals. Authors conclude that to advance as an equal society, healthcare providers should lead the way for weight stigma eradication.
Abstract
BACKGROUND In an era when obesity prevalence is high throughout much of the world, there is a correspondingly pervasive and strong culture of weight stigma. For example, representative studies show that some forms of weight discrimination are more prevalent even than discrimination based on race or ethnicity. DISCUSSION In this Opinion article, we review compelling evidence that weight stigma is harmful to health, over and above objective body mass index. Weight stigma is prospectively related to heightened mortality and other chronic diseases and conditions. Most ironically, it actually begets heightened risk of obesity through multiple obesogenic pathways. Weight stigma is particularly prevalent and detrimental in healthcare settings, with documented high levels of 'anti-fat' bias in healthcare providers, patients with obesity receiving poorer care and having worse outcomes, and medical students with obesity reporting high levels of alcohol and substance use to cope with internalized weight stigma. In terms of solutions, the most effective and ethical approaches should be aimed at changing the behaviors and attitudes of those who stigmatize, rather than towards the targets of weight stigma. Medical training must address weight bias, training healthcare professionals about how it is perpetuated and on its potentially harmful effects on their patients. CONCLUSION Weight stigma is likely to drive weight gain and poor health and thus should be eradicated. This effort can begin by training compassionate and knowledgeable healthcare providers who will deliver better care and ultimately lessen the negative effects of weight stigma.

Plain language summary
People in higher categories of obesity are at substantially increased health risk because mortality increases sharply as body mass index rises above 30. In addition to physical health risks, people with obesity commonly experience weight-related stigma. The aim of this study was to identify predictors of perceived weight stigma among patients with obesity attending general practices in socioeconomically disadvantaged urban areas of Australia. This is a cross-sectional study for which data from telephone interviews with patients with obesity were used. Patients were recruited from 17 general practices in socioeconomically disadvantaged areas of Sydney and Adelaide. Results indicate that one-third of the sample had experienced direct forms of weight discrimination in the week before being interviewed. Furthermore, weight discrimination was more likely to be experienced by patients in higher obesity categories, who were not employed, who spoke a language other than English at home and who had lower scores on the Health Literacy Questionnaire domain (that measures the ability to actively engage with healthcare providers). Authors conclude that weight stigma may compound other forms of social disadvantage. Thus, strategies are needed to address weight stigma at the individual, system and population levels and to educate primary care providers to be more alert to the needs of their patients with obesity.
Abstract
BACKGROUND Rates of obesity have increased globally and weight stigma is commonly experienced by people with obesity. Feeling stigmatised because of one's weight can be a barrier to healthy eating, physical activity and to seeking help for weight management. The aim of this study was to identify predictors of perceived weight among middle-older aged patients with obesity attending general practices in socioeconomically disadvantaged urban areas of Australia. METHODS As part of a randomised clinical trial in Australia, telephone interviews were conducted with 120 patients from 17 general practices in socioeconomically disadvantaged of Sydney and Adelaide. Patients were aged 40-70 years with a BMI ≥ 30 kg/m2. The interviews included questions relating to socio-demographic variables (e.g. gender, language spoken at home), experiences of weight-related discrimination, and the Health Literacy Questionnaire (HLQ). Multi-level logistic regression data analysis was undertaken to examine predictors of recent experiences of weight-related discrimination ("weight stigma"). RESULTS The multi-level model showed that weight stigma was positively associated with obesity category 2 (BMI = 35 to < 40; OR 4.47 (95% CI 1.03 to 19.40)) and obesity category 3 (BMI = ≥ 40; OR 27.06 (95% CI 4.85 to 150.95)), not being employed (OR 7.70 (95% CI 2.17 to 27.25)), non-English speaking backgrounds (OR 5.74 (95% CI 1.35 to 24.45)) and negatively associated with the HLQ domain: ability to actively engage with healthcare providers (OR 0.12 (95% CI 0.05 to 0.28)). There was no association between weight stigma and gender, age, education or the other HLQ domains examined. CONCLUSIONS Weight stigma disproportionately affected the patients with obesity most in need of support to manage their weight: those with more severe obesity, from non-English speaking backgrounds and who were not in employment. Additionally, those who had experienced weight stigma were less able to actively engage with healthcare providers further compounding their disadvantage. This suggests the need for a more proactive approach to identify weight stigma by healthcare providers. Addressing weight stigma at the individual, system and population levels is recommended. TRIAL REGISTRATION The trial was registered with the Australian Clinical Trials Registry ACTRN126400102162 .

Plain language summary
The negative health consequences of obesity are well known. Those classified as obese also suffer from discrimination which has further negative psychological and physiological effects on well-being. The aim of this study was to see if attitudes to obesity can be modified at the physiological and psychological level by priming. 70 people aged 18-53 were randomly assigned to 2 groups. One group was shown images of obesity in negative settings, the other in positive settings. All participants then viewed an actual obesity discrimination incident. Levels of the digestive enzyme salivary alpha amylase (sAA) and skin conductance (SC) were taken as measures of sympathetic nervous system (SNS) activity. Individuals in the negative priming group had significantly more SC arousal and exhibited the highest overall sAA response after viewing the incident when compared to the positively primed group. The authors conclude that clinicians addressing stigma issues should consider the use of positively primed images as a method for reducing the possible long-term physiological consequences of the negative attitudes surrounding obesity.
Abstract
The portrayal of obesity in the media is often one of negativity. Consequently, it may generate an increase in stigma. Obesity stigma, a form of social discrimination, is responsible for many of the negative psychological and physiological effects on individual wellness. These effects not only impact individual health, but also affect the economy, and ultimately, societal wellness. In an attempt to examine the influence of the media on obesity stigma, this study tested the hypothesis that positive priming would lead to a reduction in obesity stigma. To further our understanding of this relationship, we: 1) examined the role of priming on physiological measures (e.g. salivary alpha amylase and skin conductance) in 70 college students by introducing positive and negative media images of individuals with obesity, and 2) assessed psychological measures (e.g. perceived stress, need to belong, and self-esteem, and Body Mass Index). After the priming manipulation, participants read a vignette depicting the discrimination of an individual with obesity and answered subsequent questions assessing participants' attributional blame of obesity. Results of this study revealed that priming affects physiological responding to obesity stigmatization. In conclusion, these findings suggest that incorporating positive media images of individuals with obesity may be an effective tool for reducing stigma and the various physiological consequences associated with it, which in turn, can enhance societal health and wellness.

Plain language summary
Weight stigma is a psychosocial consequence in which individuals with obesity experience public discrimination and devaluation. Some individuals apply these negative stereotypes to themselves, which creates a self-directed stigma referred to as weight bias internalization (WBI). While studies have found perceived weight discrimination to be associated with an increased risk of mortality, no study has investigated the relationship between WBI and obesity on the risk of developing metabolic syndrome (MetS). The aim of this study is to examine the relationship between WBI and MetS. The authors hypothesised that among obese individuals, higher levels of WBI would be associated with increased odds of having MetS. Among the 178 obese adults recruited, 159 completed the study. Tests included anthropometric measurements, blood analysis, the Weight Bias Internalization Scale (WBIS) and the Patient Health Questionnaire. This study found that individuals who self-stigmatise may have a heightened risk of dyslipidemia, one component of MetS. Based on these results, the authors conclude that weight stigma is a chronic stressor and may contribute to poor health. Future studies are needed to identify specific pathways in which WBI exacerbates cardiometaoblic risk factors.
Abstract
OBJECTIVE Weight stigma is a chronic stressor that may increase cardiometabolic risk. Some individuals with obesity self-stigmatize (i.e., weight bias internalization, WBI). No study to date has examined whether WBI is associated with metabolic syndrome. METHODS Blood pressure, waist circumference, and fasting glucose, triglycerides, and high-density lipoprotein cholesterol were measured at baseline in 178 adults with obesity enrolled in a weight-loss trial. Medication use for hypertension, dyslipidemia, and prediabetes was included in criteria for metabolic syndrome. One hundred fifty-nine participants (88.1% female, 67.3% black, mean BMI = 41.1 kg/m2 ) completed the Weight Bias Internalization Scale and Patient Health Questionnaire (PHQ-9, to assess depressive symptoms). Odds ratios and partial correlations were calculated adjusting for demographics, BMI, and PHQ-9 scores. RESULTS Fifty-one participants (32.1%) met criteria for metabolic syndrome. Odds of meeting criteria for metabolic syndrome were greater among participants with higher WBI, but not when controlling for all covariates (OR = 1.46, 95% CI = 1.00-2.13, P = 0.052). Higher WBI predicted greater odds of having high triglycerides (OR = 1.88, 95% CI = 1.14-3.09, P = 0.043). Analyzed categorically, high (vs. low) WBI predicted greater odds of metabolic syndrome and high triglycerides (Ps < 0.05). CONCLUSIONS Individuals with obesity who self-stigmatize may have heightened cardiometabolic risk. Biological and behavioral pathways linking WBI and metabolic syndrome require further exploration.

Individuals with overweight and obesity are exposed to weight stigmatization in many domains of life, for example, in employment, in educational and health care settings, in the media as well as in interpersonal relationships. The aim of this study was to compare the psychometric properties and predictive values for health outcomes of two different self-report questionnaires (the Weight Self-Stigma Questionnaire and the Weight Bias Internalization Scale). This study was part of a larger project that investigated the impact of body contouring surgery after bariatric surgery on psychosocial aspects. It is a cross-sectional study which included all data of a subsample consisting of N = 78 patients prior bariatric surgery. Results indicate that both measures did not differ with respect to overall convergent validity and predictive values for multiple psychosocial health outcomes. Findings also showed that the Weight Bias Internalization Scale has better internal consistency compared to the Weight Self-Stigma Questionnaire. Authors suggest that clinical practice and research might give preference to the Weight Bias Internalization Scale in bariatric surgery samples because of the marginally better reliability, convergent validity, and greater predictive power.
Abstract
BACKGROUND Internalized weight stigma has gained growing interest due to its association with multiple health impairments in individuals with obesity. Especially high internalized weight stigma is reported by individuals undergoing bariatric surgery. For assessing this concept, two different self-report questionnaires are available, but have never been compared: the Weight Self-Stigma Questionnaire (WSSQ) and the Weight Bias Internalization Scale (WBIS). The purpose of the present study was to provide and to compare reliability, convergent validity with and predictive values for psychosocial health outcomes for the WSSQ and WBIS. METHODS The WSSQ and the WBIS were used to assess internalized weight stigma in N = 78 prebariatric surgery patients. Further, body mass index (BMI) was assessed and body image, quality of life, self-esteem, depression, and anxiety were measured by well-established self-report questionnaires. Reliability, correlation, and regression analyses were conducted. RESULTS Internal consistency of the WSSQ was acceptable, while good internal consistency was found for the WBIS. Both measures were significantly correlated with each other and body image. While only the WSSQ was correlated with overweight preoccupation, only the WBIS was correlated with appearance evaluation. Both measures were not associated with BMI. However, correlation coefficients did not differ between the WSSQ and the WBIS for all associations with validity measures. Further, both measures significantly predicted quality of life, self-esteem, depression, and anxiety, while the WBIS explained significantly more variance than the WSSQ total score for self-esteem. CONCLUSIONS Findings indicate the WSSQ and the WBIS to be reliable and valid assessments of internalized weight stigma in prebariatric surgery patients, although the WBIS showed marginally more favorable results than the WSSQ. For both measures, longitudinal studies on stability and predictive validity are warranted, for example, for weight-related and psychosocial outcomes.

Plain language summary
Obesity is a worldwide problem. General Practitioners (GPs) are usually the first port of call for many obese patients and so they are in a good position to be able to take action. The problem is that many GPs are not taking advantage of this opportunity. The aim of this study was to understand the views of GPs on obesity and what they see as their role in the treatment of this disease. 16 GPs in Portugal were interviewed face-to-face; a specific set of open questions was used to structure the interviews. 3 main themes came out of this study: 1) obesity as a public health concern, 2) obese characteristics vs treatment demands 3) GPs’ sense of defeat vs need to treat. The authors concluded that GPs do understand their role in obesity management and prevention but they hold negative views about obese patients that seem to be affecting their practices. This should be taken into account during training. More research is needed in this area to help GPs in their role to combat the obesity pandemic.
Abstract
OBJECTIVES Several studies indicate that general practitioners (GPs) are not taking the issue of obesity as seriously as they should. Therefore, the aim of this study was to understand GPs' views about obesity and obese people and how these professionals perceive their role in the treatment of this disease. STUDY DESIGN Qualitative study using semi-structured interviews. METHODS Sixteen semi-structured interviews were conducted with Portuguese GPs. Data were analyzed according to thematic analysis procedures. RESULTS GPs are negative about their own role in obesity treatment. Although they believe it is part of their job to advise obese patients on the health risks of obesity, the majority of doctors think they are not making any difference in getting their patients to make long term lifestyle changes. GPs hold negative attitudes towards these patients blaming them for being unmotivated and non-compliant and are also pessimistic about their ability to lose weight. Doctors are facing a dilemma in their practices: they want to play an active role but, due to a set of negative beliefs and perceived barriers, they are playing a relatively passive role, feeling defeated and unmotivated, which is reflected in a decrease of efforts and a willing to give up on most of the cases. CONCLUSIONS This issue should be taken in to account during physicians' education since doctors should be aware of how their own beliefs and attitudes influence their behaviour and practices, compromising, therefore, the adherence to and the success in obesity treatment. They seem to need more precise guidelines and better tools for screening and management of obesity, more referral options, and improved coordination with other specialities.

Plain language summary
Obesity is a multifactorial disease, which makes it a complicated issue to address. In particular psychology and a concept know as locus of control plays a huge role. Locus of control refers to an individual’s ability to acknowledge that their environment and choices are under their control. However, whether this is a cause of obesity or mutually occurring is unclear. This review of 49 papers aimed to determine the relationship between obesity and locus of control. The authors discussed that the majority of literature agrees on a correlation between locus of control and obesity, however it is not straight forward as there is no set definition for locus of control. Whether locus of control causes obesity or obesity causes locus of control was also difficult to determine, but it was stated that locus of control is difficult to change. The mechanisms behind causation were discussed and stress hormones and hormones which make you feel full or hungry were implicated. It was concluded that there is a correlation between locus of control and obesity, however which one is causal, still needs more research. This paper could be used by healthcare practitioners to understand the important role that psychology plays in the development of obesity.
Abstract
In the developed world, the hazards associated with obesity have largely outstripped the risk of starvation. Obesity remains a difficult public health issue to address, due in large part to the many disciplines involved. A full understanding requires knowledge in the fields of genetics, endocrinology, psychology, sociology, economics, and public policy - among others. In this short review, which serves as an introduction to the Frontiers in Endocrinology research topic, we address one cross-disciplinary relationship: the interaction between the hunger/satiation neural circuitry, an individual's perceived locus of control, and the risk for obesity. Mammals have evolved a complex system for modulating energy intake. Overlaid on this, in humans, there exists a wide variation in "perceived locus of control" - that is, the extent to which an individual believes to be in charge of the events that affect them. Whether one has primarily an internal or external locus of control itself affects, and is affected by, external and physiological factors and has been correlated with the risk for obesity. Thus, the path from hunger and satiation to an individual's actual behavior may often be moderated by psychological factors, included among which is locus of control.
