The Modified Weight Bias Internalization Scale: measurement invariance by weight status and race among undergraduate women.

BACKGROUND: Internalized weight bias is the belief in negative, weight-based stereotypes and the application of these stereotypes to oneself. These negative stereotypes have harmful impacts on people with overweight/obesity, and weight-based discrimination is well-documented across a variety of settings. Given poor outcomes associated with internalized weight bias, particularly among individuals with obesity, it is necessary to validate measures assessing internalized weight bias among diverse samples. The present study sets out to investigate measurement invariance properties across weight status (women with vs. without overweight/obesity) and race (White vs. Asian; White vs. bi- or multi-racial) of the Modified Weight Bias Internalization Scale (WBIS-M), an 11 item self-report measure. METHODS: Participants were 746 racially/ethnically diverse women across the weight spectrum (24.9% with overweight/obesity). Confirmatory factor analyses of the WBIS-M were initially performed among the full sample, and all sub-samples. Each model showed good to excellent descriptive model fit. Subsequent analyses examined factor loadings and item thresholds of the WBIS-M to assess metric, threshold, and scalar invariance. Invariance was determined by assessing changes in Comparative Fit Index (ΔCFI ≤ -0.010), Root Mean Square Error of Approximation (ΔRMSEA ≤ 0.015), and Standardized Root Mean Square Residuals (ΔSRMR ≤ 0.030). RESULTS: Based on these previously established statistical cutoffs, the WBIS-M showed invariance across weight status and racial groups in the present sample. The current results lend support for use of the WBIS-M to measure internalized weight bias in women who do and do not have overweight/obesity, and among White, Asian, and bi- or multi-racial women. CONCLUSION: This may inform future studies that wish to utilize the WBIS-M, such as investigations of mean level differences in internalized weight bias. These findings may have clinical applications in the treatment and prevention of obesity, given the heightened levels of internalized weight bias and weight-based discrimination faced by individuals with higher body weights.

Longitudinal associations of internalized weight stigma with physical activity and weight loss.

Objective: Cross-sectional research has demonstrated that internalized weight stigma (IWS) is associated with less engagement in weight management behaviors, including physical activity. However, limited research has explored longitudinal relationships among IWS, physical activity, and weight loss. This study examined longitudinal associations of changes in IWS, physical activity, and weight and tested whether physical activity mediated the relationship between IWS and weight change. Methods: Individuals with obesity and high IWS (N = 105) participated in a 72-week behavioral weight loss intervention, with or without a weight stigma intervention. Measures of IWS (Weight Self-Stigma Questionnaire), physical activity (accelerometry and self-report), and weight were collected at baseline and weeks 20, 46 and 72. Correlations examined relationships among changes in variables from baseline to all timepoints, controlling for treatment condition. Mediation, controlling for treatment condition, tested whether IWS reductions during the first 20 weeks predicted greater weight loss at weeks 46 and 72 via increased physical activity between weeks 20 and 46 or 72. Results: Decreases in IWS at week 20 were associated with greater week-20 weight loss (r = 0.265, p = 0.012). Physical activity was not a significant mediator, but greater reductions in IWS at week 20 predicted greater week-46 weight loss with or without controlling for physical activity (WSSQ: b = 0.30, confidence interval: 0.12, 0.54). Significant associations were not found at week 72. Conclusion: Initial reductions in IWS were associated with greater week-46 weight loss. Further research should investigate whether reducing IWS early in obesity treatment enhances long-term outcomes. Clinical trial registration: ClinicalTrials.gov (NCT03704064).

Chinese version of the Tendency to Avoid Physical Activity and Sport (TAPAS) scale: testing unidimensionality, measurement invariance, concurrent validity, and known-group validity among Taiwanese youths.

BACKGROUND AND OBJECTIVES: Psychosocial factors affect individuals' desire for physical activity. A newly developed instrument (Tendency to Avoid Physical Activity and Sport; TAPAS) has been designed to assess the avoidance of physical activity. Considering cultural differences could be decisive factors, the present study aimed to translate and validate the TAPAS into Chinese (Mandarin) for Taiwanese youths, and further cultural comparisons are expected. METHODS: Standard translation procedure (i.e., forward translation, back translation, and reconciliation) was used to translate the English TAPAS into the Chinese TAPAS. Following translation, 608 youths (mean [SD] age 29.10 [6.36] years; 333 [54.8%] women) participated in the study via a snowballing sampling method with an online survey. All participants completed the Chinese TAPAS and additional instruments assessing weight stigma and psychological distress. Confirmatory factor analysis (CFA) was used to examine the factor structure of the Chinese TAPAS and multigroup CFA to examine measurement invariance across gender (men vs. women) and weight status (overweight vs. non-overweight). Pearson correlations were used to examine the concurrent validity; independent t-tests between gender groups and weight status groups were used to examine the known-group validity. RESULTS: Consistent with the English version, the Chinese TAPAS was found to have a one-factor structure evidenced by CFA results. The structure was invariant across gender and weight status groups evidenced by multigroup CFA results. Concurrent validity was supported by significant associations with the related constructs assessed (r = 0.326 to 0.676; p < 0.001). Known-group validity was supported by the significant differences in TAPAS total scores between gender and weight status groups (p = 0.004 and < 0.001; Cohen's d = 0.24 and 0.48). CONCLUSION: The Chinese version of the TAPAS is a valid and reliable instrument assessing individuals' avoidance of physical activity and sports due to underlying psychosocial issues among Taiwanese youths. It is anticipated to be applied within a large Asian population, as well as cross-cultural comparisons, for further explorations in health, behavioral and epidemiological research and practice.

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 stigma is associated with body mass index among college students in Taiwan: the mediated role of internalized weight stigma.

BACKGROUND: Weight stigma is an issue often studied in Western countries; however, such information is scarce in Asian studies. METHODS: This study aimed to examine the role of internalized weight stigma as a mediator in the relationship between perceived weight stigma and changes in body mass index (BMI). The data were collected through a longitudinal online survey with two phases (n = 974; Phase 1: August and September 2021; Phase 2: November and December 2021). The Perceived Weight Stigma Scale (PWSS), Weight Self-Stigma Questionnaire (WSSQ), and Depression, Anxiety, Stress Scale - 21 (DASS-21) were administered to assess perceived weight stigma, internalized weight stigma, and psychological distress. Hierarchical regressions were used to examine the proposed model, and Hayes' Process Macro was used to test a mediation model. RESULTS: The changes in perceived weight stigma and internalized weight stigma were significantly and positively associated with changes in BMI. There were significant and positive associations between perceived weight stigma, internalized weight stigma and psychological distress over time. Change in internalized weight stigma was found to be a significant mediator in the association of change in perceived weight stigma with change in BMI for the entire sample (unstandardized coefficient = 0.04; 95% CI = 0.02, 0.06), female subgroup (unstandardized coefficient = 0.05; 95% CI = 0.02, 0.08), and male subgroup (unstandardized coefficient = 0.03; 95% CI = 0.01, 0.06). Change in perceived weight stigma also had significant effects on change in BMI for the entire sample and the female subgroup, but not for the male subgroup. CONCLUSION: Because perceived weight stigma may significantly impact changes in BMI through internalized weight stigma, treatment strategies to ameliorate self-stigma may enhance the results of weight-reduction programs. Such treatment strategies should be considered for inclusion in weight-loss interventions.

Weight stigma is commonly studied in Western countries rather than in Asian ones. To further explore how internalized weight stigma mediates the relationship between perceived weight stigma and the changes in body mass index (BMI), the study collected data through a longitudinal online survey with two phases by applying the Perceived Weight Stigma Scale (PWSS), Weight Self-Stigma Questionnaire (WSSQ) and Depression, Anxiety, Stress Scale − 21 (DASS-21) to assess perceived weight stigma, internalized weight stigma, and psychological distress. The changes in perceived and internalized weight stigma were significantly and positively associated with changes in BMI. There were significantly positive associations between perceived weight stigma, internalized weight stigma, and psychological distress over time. Based on the findings, treatment strategies to alleviate self-stigma may enhance the results of weight-reduction programs and should be considered for inclusion in weight-loss interventions.

Skepticism of and critical thinking about media messages: Conflicting relationships with body dissatisfaction.

Despite the theoretical connection between media literacy and body dissatisfaction, empirical findings about their relationship are decidedly mixed. There is not a clear explanation for these discrepancies. The present study aimed to 1) compare the attitudes young adult women with those of a reference group of adolescents to examine whether similar values were observed despite differences in age group and racial/ethnic identity, 2) to examine the relationships between media literacy and body dissatisfaction using recommended measures of media literacy. Racially diverse female undergraduate students (N = 152, Mage = 21.62) completed the Media Attitudes Questionnaire, the Critical Thinking about Media Measure, and the Body Shape Questionnaire online. Young adult women endorsed greater critical thinking about media messages and greater skepticism towards the similarity of media messages than adolescents. Additionally, greater skepticism towards the desirability and realism of media messages was associated with lower body dissatisfaction while greater critical thinking about media messages was found to be positively related to greater body dissatisfaction. It is possible that greater critical thinking within the context of media literacy cannot occur without increased attention towards or time spent thinking about media messages. Findings suggest that enhancing critical thinking about the media may not be the main mechanism of change for effective media literacy interventions. These findings underscore the complexities that exist within the relationships between media literacy and body dissatisfaction and highlight the continued need for research in this area.

Delivering a media literacy intervention for body dissatisfaction using an app-based intervention: A feasibility and pilot trial.

Body dissatisfaction rates continue to remain high, and the consequences remain dire, especially among young women. Traditional media literacy interventions have found success in addressing body image-related constructs, though they are limited in their reach and are often quickly outdated. This study was designed to examine the feasibility and acceptability of delivering a media literacy intervention via ecological momentary intervention. This pilot study tested a media literacy intervention delivered via a smartphone app designed to disrupt the connection between media use and body dissatisfaction. Thirty-seven undergraduate women (Mage = 21.17; SD = 2.20) received a 15-day media literacy intervention through a smartphone application. The primary outcomes were completion rates, retention rates, percentage of data points lost to technological errors, and participant feedback. The secondary outcome was change in body dissatisfaction. The retention and percentage of data points lost to technological errors, alongside participants' ratings, indicated that this intervention is feasible and acceptable. Several targets were identified to increase participant acceptance and potential efficacy of the intervention. Trait body dissatisfaction decreased, though not significantly, following the intervention. State body image satisfaction improved significantly from the first day to the last day of engagement with the app. Overall, the intervention was deemed feasible and acceptable, opening the door for future research in which the intervention and its delivery system are improved, and its efficacy is reexamined. Future digital media literacy interventions should focus on building a user-centered app, further reducing participant burden, and testing efficacy in large and diverse samples.

Long-term effects of an internalized weight stigma intervention: A randomized controlled trial.

OBJECTIVE: To test the long-term effects of a group-based, psychological intervention designed to reduce internalized weight stigma (IWS, i.e., self-stigma), delivered in combination with behavioral weight loss (BWL) treatment, compared to BWL alone. METHOD: Adults with obesity who had experienced and IWS (N = 105, Mage = 49 years, 90.5% women, 70.5% White, 24.8% Black, MBMI = 38 kg/m²) were randomized to receive BWL with the Weight Bias Internalization and Stigma (BIAS) Program or BWL alone. Participants received weekly group treatment for 20 weeks, followed by 52 weeks of monthly and every-other-month sessions. Percent weight change at Week 72 was the primary outcome, with secondary outcomes of weight change at other time points; physical activity (measured by accelerometry, interview, and self-report); cardiometabolic risk factors; and psychological and behavioral outcomes. Intention-to-treat analyses used linear mixed models to test for between-group differences. Treatment acceptability was assessed. RESULTS: Participants in the BWL + BIAS versus BWL group lost 2 percentage points more of baseline weight at Week 72, which was not a significant difference (mean weight change = -7.2% vs. -5.2%, 95% CI [-4.6 to 0.6], p = 0.14, d = 0.18). The BWL + BIAS (vs. BWL) group produced significantly greater improvements in weight self-stigma, eating self-efficacy, and some aspects of quality of life at specific time points. Most outcomes improved significantly over time but did not differ between groups. The trial had high retention and treatment acceptability, with higher ratings in the BWL + BIAS versus BWL group. CONCLUSIONS: No significant differences in weight loss were observed between the BWL + BIAS versus BWL group. Possible benefits of addressing weight stigma in weight management warrant further investigation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The Relationship Between Weight Stigmatization, Avoidance, Enjoyment and Participation in Physical Activity and Sport, and Psychological Distress.

Objectives: The psychosocial factors affecting physical activity (PA) and sport participation are not well understood but need to be to gain the psychological benefits of PA and sport. In this study, we sought to establish the relationship between weight stigmatization, the tendency to avoid, or participate in and/or enjoy PA and sport, and psychological distress.Methods: We collected demographic details and measures of the constructs of interest from 578 undergraduate students via an online survey. We ran bivariate correlations and multivariate linear regression models to establish statistical relationships between the variables of interest. Results: In bivariate correlations, weight stigmatization and the tendency to avoid PA were significantly associated with greater psychological distress. Greater enjoyment of PA and sport was related with less psychological distress; however, participation in PA and sport was not associated with psychological distress. In multivariate regression analyses, weight stigma, internalized weight stigma and the tendency to avoid PA and sport were significant predictors of psychological distress, accounting for 22% of the variance in psychological distress scores.Conclusion: In this study, we found that addressing internalized weight stigma requires urgent action to promote better mental health through PA and sport participation. We propose a conceptual model to explore these relationships.

Associations between social media addiction, psychological distress, and food addiction among Taiwanese university students.

BACKGROUND: Worldwide, 60% of people use social media. Excessive and/or addictive use of social media termed "problematic social media use", has been reported to negatively influence psychological and physiological health. Therefore, we proposed an illustrated model to investigate the associations between social media addiction, psychological distress and food addiction among Taiwanese university students. METHODS: A total of 598 participants (mean age = 22.8 years) completed an online survey comprising the Bergen Social Media Addiction Scale (BSMAS) assessing social media addiction, the Depression Anxiety and Stress Scale (DASS-21) assessing psychological distress, and the Yale Food Addiction Scale 2.0 (YFAS 2.0) assessing food addiction. RESULTS: Structural equation modeling showed the significant associations between BSMAS and DASS-21 (standardized coefficient [ß] = 0.45; p < 0.01) and between DASS-21 and YFAS 2.0 (ß = 0.43; p < 0.01). In addition, mediation effect with 100 bootstrapping samples showed the indirect effect of DASS-21 in the association between BSMAS and YFAS 2.0 CONCLUSIONS: The present study details the relationships between social media addiction and psychological distress as well as food addiction. The results suggest the need for interventions aimed at reducing these negative outcomes. Coping strategies for improving self-control or reducing weight-related stigma, such as food consumption monitoring or mindfulness, could be adopted for at-risk individuals to address these problems.

Social media addiction has been found to have psychological and physiological impacts on individuals' health. In order to better understand the role of social media addiction, the present study constructed a model to investigate the potential mechanism of social media addiction in affecting the individuals' food addiction level. The findings showed a clear pathway between social media addiction and food addiction with the involvement of psychological distress. Accordingly, we suggested that individuals with the potential risk of social media addiction should pay attention to their psychological status and food intake. The potential effect of weight-related stigmatization would also need to be considered, strategies such as mindfulness or food consumption monitoring would be beneficial to address the issues.

The effect of time spent sitting and excessive gaming on the weight status, and perceived weight stigma among Taiwanese young adults.

Background: During the COVID-19 pandemic, physical inactivity and sedentary behaviors (i.e., longer sitting time and excessive gaming) increased because governments across the globe adopted stringent mitigation strategies such as social distancing and lockdowns to curb the spread of the virus. Excessive gaming was one of the coping mechanisms used to deal with the pressure associated with the pandemic. Moreover, perceived weight stigma (PWS) and weight status became more salient concerns among young adults during the COVID-19 pandemic. The current study sought to investigate the relationship between time spent sitting, excessive gaming, weight status, and PWS of Taiwanese Young adults. Additionally, weight status and PWS were examined as mediators between both sedentary behaviors. Methods: This cross-sectional study involved 600 participants who were recruited through Taiwan universities. All participants completed a demographic questionnaire (including weight and height) and self-report measures including the International Physical Activity Questionnaire short form (IPAQ-SF), the Perceived Weight Stigma Scale (PWSS), and the Internet Gaming Disorder Scale-short form (IGDS9-SF). PROCESS model was performed to test the potential mediation roles of weight status and PWS. Moreover, we categorized participants into two groups based on the sitting-time item in the IPAQ-SF: students whose sitting time was less than 8 h daily, and those more than 8 h daily. Results: The group that had less than 8 h had significantly higher PWS and IGDS9-SF scores than the other group. Sitting time was negatively associated with weight status, PWS, and IGDS9-SF. Additionally, we found a significantly direct effect between time spent sitting and excessive gaming. Both weight status and PWS were significant mediators in the association between time spent sitting and excessive gaming.Conclusions: The present study demonstrated important negative correlates of excessive sedentary behaviors. Prevention efforts should focus on promoting physical activity and providing information to decrease sedentary behavior among university students.

Weight Stigma among Young Adults in Thailand: Reliability, Validation, and Measurement Invariance of the Thai-Translated Weight Self Stigma Questionnaire and Perceived Weight Stigma Scale.

The previous studies found that the Weight Self Stigma Questionnaire (WSSQ) and Perceived Weight Stigma Scale (PWSS) have shown well-established psychometric properties for measuring weight stigma with strong reliability and validity from different languages. However, there is a lack of an appropriate instrument in assessing weight stigma in Thai samples. This study aimed to examine the Thai WSSQ and PWSS among Thai university students. Both instruments were also assessed for their measurement invariance across gender and weight status subgroups. A cross-sectional study was conducted on 801 university students in Thailand between January 2022 and July 2022. All participants completed a demographic questionnaire and a Thai version of the WSSQ, PWSS, and Depression Anxiety Stress Scale-21 (DASS-21) via an online survey. Reliability, validity, measurement invariance, and correlational analyses were performed to investigate whether the Thai versions of the WSSQ and PWSS psychometric properties were acceptable. Both translated questionnaires demonstrated overall acceptable psychometric properties and revealed a two-dimensional structure for the WSSQ, and unidimensional structure for the PWSS. Measurement invariance was obtained across gender and weight status subgroups. Additionally, both translated WSSQ and PWSS were significantly correlated with DASS-21. The Thai-translated WSSQ and PWSS showed strong validity, reliability, and factorial invariance across different subgroups for measuring weight stigma among Thai university students.

Weight Stigma and Avoidance of Physical Activity and Sport: Development of a Scale and Establishment of Correlates.

Participation in sport and physical activity (PA) is declining, and the psychosocial factors underpinning avoidance of these activities are not understood. This study developed and tested a new measure assessing the tendency to avoid PA and sport because of weight stigma and appearance-related concerns. University students (n = 581, mean age = 19.8 years) completed an online survey at two time points. Demographic details and measures of weight stigmatization, appearance evaluations, and enjoyment and participation in PA or sport were taken. In addition, we developed and tested a new measure of the tendency to avoid physical activity and sport (TAPAS). Psychometric testing of the scale was conducted, and correlates of TAPAS were examined. The ten-item TAPAS provided a single factor solution, and the final scale score was predictive of lower levels of enjoyment of, and participation in, physical activity and sport (p < 0.001). The scale also displayed good internal and test-retest reliability. This study provides a new measure for assessing people's tendency to avoid PA and sport because of weight stigma or appearance-related concerns. The results suggest that initiatives seeking to increase participation in PA and sport may need to address weight stigma and associated appearance related concerns.

Mindful eating, intuitive eating, and the loss of control over eating.

BACKGROUND: The loss of control over eating (LOCE) is frequently cited as a core process of eating disturbances. In contrast, mindful eating and intuitive eating have been identified as adaptive styles of eating and have been associated with positive psychological constructs. Therefore, the present study aimed to investigate whether mindful or intuitive eating are potential protective factors for the loss of control over eating. METHODS: 1155 participants (64.2 % female) were recruited from a large university. Participants were administered select subscales of the Intuitive Eating Scale - 2nd edition (IES-2) and Mindful Eating Questionnaire (MEQ), and the brief Loss of Control over Eating Scale (LOCES-B). RESULTS: Controlling for BMI and age, intuitive and mindful eating were significantly associated with LOCE, F (8,966) = 114.78, p < .001, R2 = 0.49. Both IES-2 subscales were negatively associated with LOCE: 1) eating for physical rather than emotional reasons and 2) reliance on hunger and satiety cues, p < .001. One MEQ subscale was negatively associated with LOCE: disinhibition, p < .001. The MEQ subscales assessing awareness and external cues were not significantly associated with LOCE. CONCLUSIONS: Results suggest that while some forms of mindful eating and intuitive eating are potential protective factors, others may be less relevant to LOCE. These findings have implications for treatment, as they suggest intuitive eating may counteract the loss of control over eating. The findings also provide evidence for convergent validity of the LOCES by clarifying positive constructs that may protect against the development of this core eating pathology.

Body Checking and Body Image Avoidance as Partial Mediators of the Relationship between Internalized Weight Bias and Body Dissatisfaction.

Internalized weight bias is associated with body image disturbances and the development of disordered eating. The association between weight bias internalization and body dissatisfaction has proven difficult to disrupt. In order to develop more effective interventions, we must identify the behavioral targets which account for this robust association. The present study sought to examine whether body checking and body image avoidance mediate the relationship between weight bias internalization and body dissatisfaction. In total, 279 female undergraduates (Mage = 20.13, SD = 4.10) were administered a battery of survey measures. Results demonstrated that body checking partially mediates the relationship between weight bias internalization and body dissatisfaction, Z = 7.42, p < 0.001. Body image avoidance was also found to partially mediate the relationship between weight bias internalization and body dissatisfaction, Z = 70.03, p < 0.001. These findings suggest that body checking and body image avoidance may both partially account for the association between weight bias internalization and body dissatisfaction. These findings extend the existing literature on weight bias internalization by highlighting two behavioral targets for prevention and intervention efforts. Understanding these relationships has important implications for both reducing weight bias internalization and improving body dissatisfaction.

Evaluation of two weight stigma scales in Malaysian university students: weight self-stigma questionnaire and perceived weight stigma scale.

BACKGROUND: This study aimed to examine the psychometric properties of the Weight Self-Stigma Questionnaire (WSSQ) and Perceived Weight Stigma Scale (PWS) among Malaysian university students. METHODS: University students who were studying in a Malaysia university with a mean age of 24.0 years (n = 380; females 71.6%) were recruited through convenience sampling between 19 August and 30 September 2021. They completed a Google Form consisting of information on sociodemographic background, weight stigma, psychological distress and self-reported body weight and height. Psychometric testing was conducted using the classical test theory (including confirmatory factor analysis) and Rasch models to confirm the two-factor structure of WSSQ and the unidimensional structure of the PWS using the various fit indices. Concurrent validity of the total scores of WSSQ and PWS with psychological distress and body mass index (BMI) was also investigated. Internal consistency using Cronbach's alpha was conducted. RESULTS: The confirmatory factor analyses and Rasch analyses verified the two-factor structure for the WSSQ and the single-factor structure for the PWS. Both the WSSQ and PWS showed good internal consistency and good concurrent validity as demonstrated by their significant correlations with psychological distress and BMI. CONCLUSION: The WSSQ and PWS have strong validity and reliability, and they can both be used to assess weight stigma among Malaysian university students. LEVEL OF EVIDENCE: V: Descriptive study.

The mediation effect of perceived weight stigma in association between weight status and eating disturbances among university students: is there any gender difference?

BACKGROUND: The study aimed to examine the association between perceived weight stigma (PWS), weight status, and eating disturbances. We hypothesized that PWS would partially mediate the association between weight status and eating disturbances among university students. METHODS: The study involved 705 undergraduate students (379 females and 326 males) recruited from Hong Kong and Taiwan Universities (399 Hong Kong; 306 Taiwan participants). Our sample was from one Hong Kong university (located in Kowloon) and five Taiwan universities (three located in Southern Taiwan, one located in Central Taiwan, and one located in North Taiwan). Participants' mean age was 20.27 years (SD = 1.79). All participants completed a demographic information sheet, the Three-Factor Eating Questionnaire-18 (TFEQ-R18), and the PWS questionnaire. PROCESS macro models were used to analyze potential mediations. RESULTS: We found a significantly higher PWS scores in a high weight group for females and males. There was a significant difference between weight status and eating disturbances. Moreover, PWS partially mediated the association between weight status and eating disturbances for both genders. CONCLUSIONS: PWS is associated with weight status and eating disturbances, making it an important target for health improvement among young adults. Further studies are needed to corroborate such associations in participants from other societies and cultures.

Perceived weight stigma, weight status (e.g., low weight, average weight, and high weight) and eating disturbances have been found to have associations between each other. However, such research is needed among Asians, and the present study examined a mediation mechanism among the three factors (i.e., perceived weight stigma, weight status, and eating disturbances). Using data from 705 university students across two regions (Hong Kong and Taiwan), the present study revealed that weight status might be associated with perceived weight stigma, and perceived weight stigma might be associated with eating disturbances. Such findings were consistent across male and female university students. The present study's findings underscore the importance of perceived weight stigma. Reducing perceived weight stigma may be an important strategy in developing health eating behaviors among university students.
