The relationship between weight bias internalization and healthy and unhealthy weight control behaviours

Presentation of a weight bias internalization tool for use in pregnancy and a call for future research: A commentary

Background

Emerging evidence has shown that weight stigma is a concern during pregnancy, with several studies documenting common sources including healthcare, the media and interpersonal networks. Experiencing weight stigma may lead to weight bias internalization (WBI), whereby individuals accept and self-direct negative weight-related stereotypes, and limited research has assessed this in the context of pregnancy. Pregnancy is unique in terms of weight changes as many individuals will experience gestational weight gain (GWG). Accordingly, a WBI tool that accounts for GWG may be a more population-specific resource to use.

Methods

This commentary presents a pregnancy-specific WBI tool that accounts for GWG. The validated Adult WBI scale was modified to include 'pregnancy weight gain'. This commentary also presents a brief summary of research that has assessed WBI in pregnancy and recommendations for future work.

Results

Recommended future work includes validation of the pregnancy-specific WBI tool and prospective examinations of weight stigma and WBI in pregnancy and implications on maternal and newborn outcomes.

Conclusion

Ultimately this research may inform development of interventions and resources to mitigate weight stigma and WBI in pregnancy and overall may contribute to improving prenatal outcomes and experiences.

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.

Weight Stigma Associated With Mental Health Concerns Among College Students

INTRODUCTION

Weight stigma is widespread and exists across numerous domains including health care, educational institutions, workplaces, mass media, and interpersonal relationships. Weight stigma experienced during the college years may be particularly consequential because the college years are a period of increased vulnerability for the development of mental health concerns. The purpose of the present study was to examine how experiences of weight stigma relate to mental health concerns, including symptoms of eating disorders, anxiety, and depression, among college students.

METHODS

Prevalence of interpersonal and anticipated weight stigma was examined among 2,707 students participating in the 2018-2019 and 2019-2020 Healthy Minds Study and tested for differences in prevalence across student characteristics. Logistic regression was used to explore relationships between measures of weight stigma and student mental health. Analyses were conducted in 2021-2023.

RESULTS

Interpersonal and anticipated weight stigma were reported by 12.3% and 15.3% of students, respectively. Experiences of interpersonal and anticipated weight stigma were generally lowest among cisgender male students, heterosexual students, those with the fewest financial concerns, and those who did not perceive themselves to be "overweight." Both interpersonal and anticipated weight stigma were associated with elevated odds of high weight concerns, past-month binge eating, past-month purging, high eating disorder risk, moderate/severe anxiety symptoms, and moderate/severe depressive symptoms.

CONCLUSIONS

Findings implicate interpersonal and anticipated weight stigma as potential risk factors for a range of mental health concerns. Weight stigma is an under-recognized and under-funded public health problem.

Weight discrimination, BMI, or weight bias internalization? Testing the best predictor of psychological distress and body dissatisfaction

OBJECTIVE

This study aimed: (1) to compare psychological distress (PD) and body dissatisfaction (BD) in terms of BMI, weight bias internalization (WBI), and weight discrimination (current and past); (2) to assess the best predictor of PD and BD and assess the relationships with weight discrimination, BD, and WBI.

METHODS

The sample consisted of 1283 participants across all BMI categories, recruited through the internet voluntarily. People with obesity were the most predominant (26.1%). Experiences of weight-based discrimination were reported by participants across all BMI categories, and they were more prevalent in people with obesity.

RESULTS

People with obesity, those with WBI, and those who faced current and past weight discrimination reported higher PD and higher BD. However, WBI was the best predictor after controlling for BMI, WBI, and current and past weight discrimination. Mediation analyses revealed that the relationship between weight discrimination and BD through WBI was significant, as was the relationship between weight discrimination and WBI through BD.

CONCLUSIONS

These results stressed the importance of WBI in PD and the role of weight discrimination in WBI and BD. Hence, there is a need to better understand how WBI is formed and to design effective interventions to reduce it.
