Young children's choices and thoughts about pro-social behaviour towards others with overweight.

OBJECTIVES: This study aimed to investigate weight bias within young children's pro-social choices between characters who differed in body size. METHODS: Seventy-six children aged 4-6 years read stories asking them to choose who they would first help, share with, comfort, and steal from, between a healthy weight and child with overweight. They also selected the one character they would most like to play with. Children's reasoning for these choices was recorded and analysed. RESULTS: The character with overweight was helped first in only a third of the choices made. Children chose the characters with overweight more often as the target for anti-social action. In friendship selections, children overwhelmingly rejected the characters with overweight. However, weight bias was not prominent in the reasons children gave for the choices. Most children were not negative about body shape, weight or appearance. Similarly, in friendship choices, these were mostly expressed positively to the character chosen. Only a small minority of children were explicitly negative about the character with overweight. CONCLUSIONS: A better understanding of weight bias acquisition and variation between children will benefit those working in health care and educational settings. Future research should link with developmental theory, such as on social categorization and theory of mind.

Implicit weight bias: shared neural substrates for overweight and angry facial expressions revealed by cross-adaptation.

The perception of facial expression plays a crucial role in social communication, and it is known to be influenced by various facial cues. Previous studies have reported both positive and negative biases toward overweight individuals. It is unclear whether facial cues, such as facial weight, bias facial expression perception. Combining psychophysics and event-related potential technology, the current study adopted a cross-adaptation paradigm to examine this issue. The psychophysical results of Experiments 1A and 1B revealed a bidirectional cross-adaptation effect between overweight and angry faces. Adapting to overweight faces decreased the likelihood of perceiving ambiguous emotional expressions as angry compared to adapting to normal-weight faces. Likewise, exposure to angry faces subsequently caused normal-weight faces to appear thinner. These findings were corroborated by bidirectional event-related potential results, showing that adaptation to overweight faces relative to normal-weight faces modulated the event-related potential responses of emotionally ambiguous facial expression (Experiment 2A); vice versa, adaptation to angry faces relative to neutral faces modulated the event-related potential responses of ambiguous faces in facial weight (Experiment 2B). Our study provides direct evidence associating overweight faces with facial expression, suggesting at least partly common neural substrates for the perception of overweight and angry faces.

Preliminary evaluation of a brief worksite intervention to reduce weight stigma and weight bias internalization.

Weight-based discrimination (WBD) is common and associated with reduced physical and emotional functioning. WBD is common in the workplace, yet no studies have evaluated a WBD intervention delivered in a worksite setting. This study evaluated the feasibility, acceptability, and preliminary effectiveness of a 3-hour, remote-delivered WBD intervention at a large public university. Six workshops including 94 participants (41.76 ± 9.37 y; 92.8% women) were delivered December 2020 through May 2021; 88.3% of participants enrolled in the study and 88.8% of enrolled participants completed pre- and post-intervention surveys. Participants strongly agreed the workshop contributed to a more inclusive work environment (M=4.98 ± 0.2; 1 =Strongly Disagree to 5 =Strongly Agree); and was highly needed (4.9 ± 0.3) and liked (4.8 ± 0.5). Qualitative feedback cited benefits of remote delivery in providing body size anonymity and wanting access to intervention materials and more time for discussion and action steps to reduce WBD. Participants experienced significant, medium reductions in explicit weight bias (ps < .001), significant, small reductions in weight bias internalization (p < .001), and statistically non-significant (p = .08), small-to-medium reductions in implicit bias. Targeting worksites as a delivery mechanism has the potential to reduce WBD, thereby improving the health and well-being of diverse employees and creating a more inclusive workspace.

Exploring the association between internalized weight bias and mental health among Canadian adolescents.

BACKGROUND: Internalized weight bias (IWB) has been identified as a correlate of higher depressive and anxiety symptoms in adolescents with higher weights. However, there has been limited investigation into how IWB relates to positive mental health and whether these associations differ across genders. OBJECTIVES: To examine the associations between IWB and mental health (depression, anxiety, flourishing) in adolescents with higher weights, and to test the potential moderating role of gender. METHODS: Canadian adolescents with higher weights (N = 7538, 60% boys, 36% girls, 4% gender diverse, ages 12-19) from the COMPASS study completed a survey during the 2021-2022 school year. Data were analysed using generalized linear models. RESULTS: Highest IWB and poorest mental health were noted within gender diverse adolescents, followed by girls then boys. Gender moderated the relationship between higher IWB and higher depression, higher anxiety and lower flourishing, with the strongest relationships noted among girls. CONCLUSION: IWB interventions should be tailored to gender subgroups that may be particularly vulnerable to maladaptive mental health outcomes associated with IWB. System-level changes that mitigate perpetuation of weight bias and discrimination which lead to IWB are also essential, particularly for girls.

Is Obesity a Cause for Shame? Weight Bias and Stigma among Physicians, Dietitians, and Other Healthcare Professionals in Poland-A Cross-Sectional Study.

Weight bias and weight stigma pose significant challenges in healthcare, particularly affecting obesity management practices and patient care quality. Our study evaluates their prevalence and impact among healthcare professionals in Poland. Using the Fat Phobia Scale and custom questions, we surveyed 686 professionals via Computer-Assisted Web Interview (CAWI). Results reveal a moderate level of explicit weight bias (mean score: 3.60 ± 0.57), with significant variations across professional groups: physicians (3.70 ± 0.48), dietitians (3.51 ± 0.48), and others (3.44 ± 0.77). Common feelings towards individuals with obesity include willingness to help (57.0%) and compassion (37.8%), yet 29.9% perceive obesity as shameful. The results also vary depending on the respondent's sex or BMI. These findings underscore the need for evidence-based interventions to mitigate weight stigma and enhance understanding of obesity among healthcare professionals.

Reducing weight bias and stigma in qualitative research interviews: Considerations for researchers.

Perceptions and biases influence how we interact with and experience the world, including in professional roles as researchers. Weight bias, defined as negative attitudes or perceptions towards people that have large bodies, can contribute to weight stigma and discrimination leading to negative health and social consequences. Weight bias is experienced by people living with obesity in media, health care, education, employment and social settings. In research settings, there is potential for weight bias to impact various aspects of qualitative research including the participant-researcher dynamic in interviews. However, evidence-based strategies to reduce weight bias in qualitative research interviews have yet to be identified. We discuss how weight bias may influence research interviews and identify several considerations and strategies for researchers to minimize the impact of weight bias. Strategies include practicing reflexivity, planning and conducting interviews in ways that support rapport building, using inclusive language, and considering participatory methods.

Weight-related discrimination, perceived stress and psychological and physical well-being of persons with type 2 diabetes: A mediation analysis.

AIMS: The aim of the study was to examine perceived stress as a mediator of the association between weight-related discrimination and physical and psychological well-being among persons with type 2 diabetes (T2D). METHODS: Data were obtained from 5104 persons with self-reported T2D participating in the All of Us research programme in the United States. The Everyday Discrimination Scale, Cohen's Perceived Stress Scale (PSS) and PROMIS Global Health Scale were used to measure weight-related discrimination, perceived stress and health outcomes (physical and psychological), respectively. Mediation effects of PSS were tested by bootstrapping with 5000 random samples. RESULTS: Participants were, on average, 63.62 (SD 11.38) years old. Majority of them were female (55.53%), non-Hispanic White (72.61%), married or living with a partner (56.92%), had a household income of <$35,000 (31.99%) and had some college education (33.54%). We found that approximately 18% of study participants reported having experienced weight-related discrimination. We also found that weight-related discrimination was independently associated with poor physical and psychological well-being. These associations were partially mediated by perceived stress such that weight-related discrimination was associated with greater perceived stress, which was in turn associated with poorer physical and psychological well-being. CONCLUSIONS: Given that weight-related discrimination is associated with poor outcomes through elevated stress, interventions that target stress may disrupt this pathway thereby helping to reduce the health impact of weight-related discrimination. This assertion should, however, be tested in future studies.

Association of quality of life with internet use and weight stigma across individuals with obesity and those without obesity: Role of self-perception.

Weight status, weight stigma, and internet use are important factors impacting quality of life (QoL). However, little is known regarding how these factors interact in their association with QoL, and it is important to understand how self-perceived obesity and body mass index (BMI)-defined obesity may differentially impact QoL. We aimed to assess the associations between weight status (obesity vs. non-obesity, including both self-perceived and BMI-defined), weight stigma, internet use, and QoL. Cross-sectional data from the Taiwan Social Change Survey (N = 1604; mean age = 49.22; 52.93 % women) were used. All participants were classified as having obesity or not having obesity according to both self-perceived (self-perceived as 'too fat') and BMI-defined (≧27 kg/m2 as obesity) weight status. Results showed that the group with obesity (both BMI-defined and self-perceived) had significantly more internet time and lower physical QoL than the group without obesity. Those with self-perceived obesity, but not those with BMI-defined obesity, sought health information via the internet and used social media significantly more than the group without obesity. More internet time was associated with worse physical and mental QoL for the group with obesity regardless of BMI-defined or self-perceived status. Moreover, weight stigma was associated with worse mental QoL for the group with self-perceived obesity, but not for the group with BMI-defined obesity. Accordingly, being a person with obesity (self-defined, or based upon BMI) was associated with more internet time and poorer QoL. People with self-perceived obesity may have increased experience of weight stigma and greater internet use, factors that may contribute to their impaired QoL.

Weight Bias Among Certified Nurse-Midwives and Certified Midwives: Findings From a National Sample.

INTRODUCTION: Weight bias toward individuals with higher body weights permeates health care settings in the United States and has been associated with poor weight-related communication and quality of care as well as adverse health outcomes. However, there has been limited quantitative investigation into weight bias among perinatal care providers. Certified nurse-midwives (CNMs)/certified midwives (CMs) attend approximately 11% of all births in the United States. The aims of this study were to measure the direction and extent of weight bias among CNMs/CMs and compare their levels of weight bias to the US public and other health professionals. METHODS: Through direct postcard distribution, social media accounts, professional networks, and email listservs, American Midwifery Certification Board (AMCB)-certified midwives were solicited to complete an online survey of their implicit weight bias using the Implicit Association Test and their explicit weight bias using the Antifat Attitudes Questionnaire, Fat Phobia Scale, and Preference for Thin People measure. RESULTS: A total of 2257 midwives participated in the survey, yielding a completion rate of 17.7%. Participants were mostly White and female, with a median age of 46 years and 11 years since AMCB certification. More than 70% of midwives have some level of implicit weight bias, although to a lesser extent compared with previously published findings among the US public (P < .01) and other health professionals (P < .01). In a subsample comparison of female midwives to female physicians, implicit weight bias levels were similar (P > .05). Midwives also express explicit weight bias, but at lower levels than the US public and other health professionals (P < .05). DISCUSSION: This study provides the first quantitative research documenting weight bias among a national US sample of perinatal care providers. Findings can inform educational efforts to mitigate weight bias in the perinatal care setting and decrease harm.

Implicit and Explicit Weight Bias among Midwives: Variations Across Demographic Characteristics.

INTRODUCTION: Weight bias toward individuals with higher body weights is present in health care settings. However, there has been limited quantitative exploration into weight bias among perinatal care providers and its potential variations based on demographic characteristics. The aim of this study was to examine if the direction and extent of weight bias among midwives certified by the American Midwifery Certification Board (AMCB) varied across age, years since certification, body mass index (BMI), race, ethnicity, and US geographic region. METHODS: Through direct email listservs, postcard distribution, social media accounts, and professional networks, midwives were invited to complete an online survey of their implicit weight bias (using the Implicit Association Test) and their explicit weight bias using the Anti-Fat Attitudes Questionnaire (AFA), Fat Phobia Scale (FPS), and Preference for Thin People (PTP) measure. RESULTS: A total of 2106 midwives who identified as Black or White and resided in one of 4 US geographic regions participated in the survey. Midwives with a lower BMI expressed higher levels of implicit (P <.01) and explicit (P ≤.01) weight bias across all 4 measures except for the AFA Fear of Fat Subscale. Implicit weight bias levels also varied by age (P <.001) and years since certification (P <.001), with lower levels among younger midwives (vs older) and those with fewer years (vs more) since certification. Only age and BMI remained significant (P <.001) after adjusting for other demographic characteristics. Lower explicit weight bias levels were found among midwives who identified as Black (vs White) on 2 measures (FPS: adjusted ß = -0.07, P = .004; PTP: P = .01). DISCUSSION: This was the first quantitative study of how weight bias varies across demographic characteristics among a national sample of midwives. Further exploration is needed in more diverse samples. In addition, research to determine whether weight bias influences clinical decision-making and quality of care is warranted.

Negative familial weight talk and weight bias internalization in a US sample of children and adolescents.

BACKGROUND: Negative familial weight talk may contribute to higher weight bias internalization in pre- and early adolescents (hereafter referred to as children) and may differ by gender, weight status, and race and ethnicity. OBJECTIVE: Examine the relationship between negative familial weight talk and weight bias internalization and examine differences by gender, weight status, and race and ethnicity. METHODS: We cross-sectionally analysed 5th-7th graders (10-15 years old) living in Massachusetts (n = 375, 52.3% girls, 21.3% BMI ≥85th percentile, 54.8% non-Hispanic White). Negative familial weight talk frequency during the past 3 months was self-reported and discretized as 'never,' 'occasionally' (1-9 times) and 'often' (>9 times); the Modified Weight Bias Internalization Scale assessed weight bias internalization. Generalized linear models estimated the relationship between negative familial weight talk and weight bias internalization and sub-analyses estimated the relationship across gender, weight status, and race and ethnicity. Results are summarized as ratios of means (RoM). RESULTS: Children experiencing negative familial weight talk occasionally (RoM = 1.12, p = 0.024) and often (RoM = 1.48, p < 0.001) had significantly higher weight bias internalization than children who never experienced it. In sub-analyses, experiencing negative familial weight talk often was associated with higher weight bias internalization among girls (RoM = 1.66, p < 0.001), boys (RoM = 1.32, p = 0.007), children with BMI <85th percentile (RoM = 1.44, p = 0.007) and BMI ≥85th percentile (RoM = 1.39, p = 0.001), and non-Hispanic White children (RoM = 1.78, p < 0.001), but not Hispanic (RoM = 1.25, p = 0.085) or non-Hispanic Black children (RoM = 1.20; p = 0.31). CONCLUSIONS: Frequent negative familial weight talk was associated with higher weight bias internalization across gender and weight status and in non-Hispanic White children only.

Drivers and facilitators of weight stigma among preconception, pregnant, and postpartum women: A systematic review.

Women in the preconception, pregnant, or postpartum period are susceptible to weight stigma, particularly due to the risk of excess weight gain during the reproductive life period and the negative effects of stigma on the health of both the mother and the child. Identifying the drivers and facilitators of weight stigma will help guide focused weight stigma prevention interventions. This systematic review aimed to identify the drivers and facilitators of weight stigma among preconception, pregnant, and postpartum women. In May 2022, Medline, Embase, PsycINFO, and the Maternity and Infant Care Database were searched for peer-reviewed articles published since 2010 using search terms weight AND stigma AND preconception, OR pregnant, OR postpartum. Of the 1724 articles identified, 34 fulfilled the inclusion criteria and were included in a narrative synthesis. Women reported facing insensitive language, misconceptions about obesity across all settings, and inappropriate media representation. The unavailability of appropriate equipment at facilities was reported by both women and health professionals. Our findings indicate that a rigorous effort by all stakeholders is necessary to promote regulatory, legal, and educational initiatives designed to reduce weight stigma and discrimination against women in the reproductive period.

Weight stigma and mental health outcomes in early-adolescents. The mediating role of internalized weight bias and body esteem.

BACKGROUND: Weight stigma is increasingly common in early adolescence and may lead to weight bias internalization, with negative consequences for mental health outcomes. This study aimed to: examine the relations of perceived weight stigma and internalized weight bias with early adolescents' internalizing symptoms and disordered eating behavior; explore the mediating role of internalized weight bias on the relations of perceived weight stigma with internalizing symptoms and disordered eating behaviors; examine body esteem as a mediator between internalized weight bias and mental health outcomes. METHODS: A sample of 406 early adolescents (59.6% girls) aged between 11 and 13 participated in this cross-sectional study. They completed self-report measures assessing perceived weight stigma, internalized weight bias, body esteem, internalizing symptoms and disordered eating. RESULTS: Path analysis indicated that perceived weight stigma was positively related with internalizing symptoms and internalized weight bias. Further, internalized weight bias was negatively related with body esteem and positively related with internalizing symptoms and disordered eating. Internalized weight bias mediated the relations of perceived weight stigma with internalizing symptoms, disordered eating and body esteem. Further, body esteem mediated the relations of internalized weight bias with internalizing symptoms and disordered eating behavior. CONCLUSIONS: The findings highlight internalized weight bias as a psychological mechanism potentially explaining negative links of weight stigma with internalizing symptoms and disordered eating in early adolescence. The results emphasize the need for early intervention during this developmental stage, in order to prevent psychological and behavioral outcomes of weight stigma and internalized weight bias.

Weight biases, body image and obesity risk knowledge in the groups of nursing students from Poland and Nigeria.

Each population may have its own specific characteristics and cultural differences, which can affect perceptions of one's body, obesity, and the development of weight-related biases. The goal of our study is to (I) examine weight biases among incoming nursing students from two distinct cultures; (II) determine whether the cultural differences may be reflected in the levels of fat phobia, attitudes, and behaviors related to overweight and obesity; (III) adapt the Fat Phobia Scale and translate it into Polish. The study includes 119 Nigerian students and 120 Polish students. The following tools are used-ORK-10, ATOP, BAOP, BES and FPh. The results indicates that Nigerian students have significantly (p < 0.01) less knowledge about the risks associated with overweight and obesity. In contrast, they have a significantly (p < 0.01) more positive body image than the Polish students. Among Nigerian students, men have more positive body image in comparison to women (p = 0.01). An inverse relationship is observed in the group of Polish students, among whom women had a more positive body image than men did (p = 0.01). There are no statistically significant differences in fatphobic attitudes among the studied groups. It has been observed, that culture may be related to weight biases.

Weight stigma and allostatic load in adults: protocol for a scoping review.

INTRODUCTION: Weight-related stigma (WS) has been associated with adverse psychosocial and physical health effects. Despite the relationship between WS and allostatic load, there are no integrative reviews of this association. This scoping review aims to provide a comprehensive overview of the relationship between allostatic load biomarkers associated with WS by identifying gaps in this topic and proposing recommendations for future research. METHODS AND ANALYSIS: This protocol was guided by the methodological framework of Arksey and O'Malley and the Joanna Briggs Institute (JBI). The research questions were based on the population-concept-context framework. Studies in adults diagnosed as overweight or obese, exposed to WS and assessing the association between WS and biomarkers of allostatic load will be included. A search will be conducted in Medline (Ovid), PsycINFO (Ovid), Scopus (Elsevier), Cochrane Library (Wiley) and Google Scholar. The search strategy will be conducted in three stages, based on the JBI recommendation with the MESH terms "Social Stigma," "Weight Prejudice," "Biomarkers," "Allostasis," "Adults" and related terms. Data extraction will be done with a template adapted from JBI. The search strategy and selection process results will be presented in a flow chart and summarised in the text. The main results will be presented in a descriptive synthesis. ETHICS AND DISSEMINATION: Ethics review and approval are not required. The results will be disseminated through peer-reviewed publications, conferences, congresses or symposia.

Associations among parents' internalized weight bias, negative child-focused body talk, and feeding behaviors.

OBJECTIVE: Parents' negative body talk about children (negative weight/shape comments) and internalized weight bias (application of negative weight-based stereotypes to oneself) are associated with children's maladaptive eating behaviors, but mechanisms are poorly understood. Conceptually, parental behaviors and attitudes may translate to implicit and explicit concerns about their child's weight and influence parents' feeding practices. These associations are underexplored in the literature. METHOD: 242 parents (59.4% mothers) completed a one-time assessment that included measures of internalized weight bias, negative body talk, and feeding practices. Parents also completed assessments about one of their children, of any weight status (age range 5-15 years; 40% daughters). RESULTS: Parents' internalized weight bias was positively associated with concern about their child's weight and restriction of their child's diet. Parents' negative body talk towards their child was positively associated with concern about their child's weight and shape, restriction of their child's diet, and monitoring of their child's diet. Relative to internalized weight-bias, negative body talk had a stronger correlation with parents' concern about child weight and monitoring of child's diet. Correlations did not vary by child gender or weight category. DISCUSSION: Parents' internalized weight bias and negative body talk about their child were associated with their feeding practices across child gender and weight categories, with correlations in the small to medium range. Thus, children of all genders and weights may be vulnerable to enacted weight bias. Future studies should examine whether addressing parents' internalized weight bias and communication in family-focused interventions improves feeding practices and child well-being.

Weight bias and stigma in healthcare: What are we doing about it?

Weight bias and weight stigma is present in healthcare settings negatively affecting people with obesity. Healthcare professionals should be aware of how their potential bias and stigma may be impacting clients with obesity. With obesity projected to rise among the world, the healthcare environment needs to be more accepting and accommodating.

Obesity bias: How can this underestimated problem affect medical decisions in healthcare? A systematic review.

INTRODUCTION: Obesity is often labeled as a physical characteristic of a patient rather than a disease and it is subject to obesity bias by health providers, which harms the equality of healthcare in this population. OBJECTIVE: Identifying whether obesity bias interferes in clinical decision-making in the treatment of patients with obesity. METHODS: A systematic review of observational studies published between 1993 and 2023 in MEDLINE, Embase, and Cochrane Library on obesity bias and therapeutic decisions was carried out. The last search was conducted on June 30, 2023. The main outcome was the difference between clinical decisions in the treatment of individuals with and without obesity. The Newcastle-Ottawa scale for observational studies was used to assess for quality. After the selection process, articles were presented in narrative and thematic synthesis categories to better organize the descriptive analysis. RESULTS: Of the 2546 records identified, 13 were included. The findings showed fewer screening exams for cancer in patients with obesity, who were also susceptible to less frequent pharmacological treatment intensification in the management of diabetes. Women with obesity received fewer pelvic exams and evidence of diminished visual contact and physician confidence in treatment adherence was reported. Some studies found no disparities in treatment for abdominal pain and tension headaches between patients presented with and without obesity. CONCLUSION: The presence of obesity bias has negative effects on medical decision-making and on the quality of care provided to patients with obesity. These findings reveal the urgent necessity for reflection and development of strategies to mitigate its adverse impacts. (The protocol was registered with the international prospective register of systematic reviews, PROSPERO, under the number CRD42022307567).

A systematic review of weight stigma and disordered eating cognitions and behaviors.

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.

Sexual Assault Among College Women: The Role of Survivor Acknowledgment, Rape Myth Acceptance, Weight Bias, and Body Appreciation.

Approximately one in five college women experience a sexual assault (SA), though a meaningful percentage of survivors do not acknowledge or label their experience as such. Research indicates that acknowledgment status is often influenced by how closely SA incidents align with the "real rape" script and degree of survivor rape myth acceptance (RMA). However, studies evaluating acknowledgment paired with other attitudes and health outcomes among survivors is sparse. The current study examined the relation between acknowledgment status, RMA, weight-related constructs, and psychological well-being among three groups of college women (N = 584): non-survivors, unacknowledged survivors, and acknowledged survivors. Findings indicate that, among survivors, acknowledged compared to unacknowledged SA is significantly associated with diminished body appreciation, self-esteem, and increased internalized weight bias, though no differences in psychological distress were found.
