Weight Bias, Shame, and Self-Compassion: Risk/Protective Mechanisms of Depression and Anxiety in Prebariatic Surgery Patients

Depressive Symptoms among Bariatric Surgery Candidates: Associations with Stigmatization and Weight and Shape Concern

Bariatric surgery candidates (BSC) are a highly vulnerable group for mental health impairments. According to the theoretical model of weight stigma, weight-related experienced stigmatization (ES) negatively influences mental health through weight bias internalization (WBI). This study tested this model among BSC and investigated whether this association depends on a negative body image in terms of weight and shape concern as a potential moderator. As part of a German multicenter study, ES, WBI, weight and shape concern, and depressive symptoms were assessed via self-report questionnaires among n = 854 BSC. Simple and moderated mediation analyses were applied to analyze whether WBI influences the relationship between ES and depressive symptoms, and whether this influence depends on weight and shape concern. WBI significantly mediated the relationship between ES and depressive symptoms by partially reducing the association of ES with depressive symptoms. Weight and shape concern emerged as significant moderators in the overall model and specifically for associations between WBI and depressive symptoms. The results suggest that the association between ES and depressive symptoms among BSC is stronger in those with high WBI. This association is strengthened by weight and shape concern, especially at low and mean levels. Studies evaluating longitudinal associations between weight-related stigmatization and mental health are indicated, as well as intervention studies targeting WBI in order to reduce adverse effects of ES on mental health in BSC.

Comparison of arthroscopic debridement and microfracture in the treatment of osteochondral lesion of talus

Objective

This study was performed to compare the clinical effect of arthroscopic debridement vs. arthroscopic microfracture in the treatment of osteochondral lesions of the talus.

Methods

We retrospectively reviewed patients with osteochondral lesion of talus who were admitted to our hospital from April 2020 to April 2021. The patients were divided into Group A (arthroscopic debridement group, n = 39) and Group B (arthroscopic microfracture group, n = 42), and the intraoperative details in the two groups were analyzed. The American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were compared between the two groups before surgery and at the last follow-up.

Results

The postoperative AOFAS score (Group A, 40.9-82.26; Group B, 38.12-87.38), VAS score (Group A, 6.44-3.92; Group B, 6.38-2.05) significantly improved in both groups, but the improvement was significantly greater in Group B than in Group A (P < 0.05). Among all patients, the AOFAS and VAS scores of men aged ≤30 years and patients with a low body mass index (BMI) improved more significantly (P < 0.05).

Conclusion

The arthroscopic microfracture for the treatment of osteochondral lesion of talus is superior to joint debridement in terms of improving ankle function, especially in relatively young men with a relatively low BMI.

Examining weight bias before and/or after bariatric surgery: A systematic review

Research examining weight bias in the bariatric population, who may be at greater risk of weight stigma, is scarce. The present study aimed to systematically review the literature for quantitative evidence that explores the medical, psychosocial, and behavioral sequelae associated with experienced, internalized, and/or externalized weight bias in patients seeking or who have undergone bariatric surgery. Five databases were systematically searched for English peer-reviewed quantitative studies, which examined weight bias in a sample of individuals seeking or who had undergone bariatric surgery. Risk of bias was assessed. Twenty-nine studies were included, of which 13 examined internalized weight bias, 12 examined experienced weight bias, 4 examined both, and 0 examined externalized weight bias. Most studies were cross-sectional, and the results showed high risk of bias. The results suggested that both experienced and internalized weight bias were associated with a host of negative psychosocial, behavioral, and medical sequelae. The findings of this review underscore the need for more rigorous research to better understand the relationship between weight bias and bariatric surgery, particularly longitudinally. Future patients may benefit from research developing interventions for reducing weight bias prior to and following bariatric surgery in order to reduce the associated negative correlates and improve outcomes.

Internalised Weight Stigma Mediates Relationships Between Perceived Weight Stigma and Psychosocial Correlates in Individuals Seeking Bariatric Surgery: a Cross-sectional Study

Purpose

Research suggests that internalised weight stigma may explain the relationship between perceived weight stigma and adverse psychological correlates (e.g. depression, disordered eating, body image disturbances). However, few studies have assessed this mechanism in individuals seeking bariatric surgery, even though depression and disordered eating are more common in this group than the general population.

Materials and Methods

We used data from a cross-sectional study with individuals seeking bariatric surgery (n = 217; 73.6% female) from Melbourne, Australia. Participants (M_age = 44.1 years, SD = 11.9; M_BMI = 43.1, SD = 7.9) completed a battery of self-report measures on weight stigma and biopsychosocial variables, prior to their procedures. Bias-corrected bootstrapped mediations were used to test the mediating role of internalised weight stigma. Significance thresholds were statistically corrected to reduce the risk of Type I error due to the large number of mediation tests conducted.

Results

Controlling for BMI, internalised weight stigma mediated the relationship between perceived weight stigma and psychological quality of life, symptoms of depression and anxiety, stress, adverse coping behaviours, self-esteem, exercise avoidance, some disordered eating measures and body image subscales, but not physical quality of life or pain.

Conclusion

Although the findings are cross-sectional, they are mostly consistent with previous research in other cohorts and provide partial support for theoretical models of weight stigma. Interventions addressing internalised weight stigma may be a useful tool for clinicians to reduce the negative correlates associated with weight stigma.

From Weight Bias Internalization to Health-Related Quality of Life: Self-esteem and Psychopathology in Pre-bariatric Surgery Patients

INTRODUCTION

It has been reported that people seeking bariatric surgery have poor health-related quality of life (HRQoL). Weight bias internalization (WBI) is prevalent in this population and strongly associated with psychopathology and health status. However, the psychological mechanisms underlying the relationship between WBI and the physical and mental dimensions of HRQoL remain to be clarified.

METHODS

A preoperative sample of patients with obesity (N = 246; women = 75.2%; M_age = 32.07) completed validated measures as part of a routine preoperative psychological assessment to assess their WBI, self-esteem, anxiety symptoms, depressive symptoms, and HRQoL.

RESULTS

After controlling for the effects of gender, age, and BMI, WBI was linked to poorer physical and mental HRQoL through low self-esteem and increased psychological distress, including anxiety and depressive symptoms.

CONCLUSION

In pre-bariatric surgery patients with obesity, high WBI may predict impairments in mental and physical HRQoL by lowering self-esteem, and further increasing anxiety and depressive symptoms. Interventions targeting WBI may be an important aspect to consider in the clinical treatment of pre-bariatric surgery patients. Further longitudinal studies are warranted to determine causality.

A meta-analysis of associations between weight bias internalization and conceptually-related correlates: A step towards improving construct validity

Weight bias internalization (WBI), a process of weight-based self-devaluation, has been associated with adverse mental and physical health. However, there are limitations with the existing conceptualization and operationalization of WBI that raise questions about the implications of this evidence-base. To address these limitations, the present study investigated the construct validity of WBI by conducting a meta-analysis of associations between WBI (as currently operationalized) and conceptually-related correlates. Studies identified through October 2021 that provided zero-order correlations for associations between WBI and conceptually-related constructs were examined. Meta-regression determined whether these associations differed across WBI measures and demographic (age, sex/gender, race, BMI) and study-level (publication status, sample type, study quality) moderators. Data for 128 (sub)samples were identified (Msample size = 477.83, SD = 1679.90; Mage = 34.46, SD = 12.17; range = 10.21-56.60). Greater WBI exhibited large to very large associations with factors suggested to have considerable overlap with this construct (negative and positive body image, self-devaluation), general and weight-specific experiential avoidance, and individuals' anticipation of future weight stigma. Associations varied for other constructs that have been differentially included in conceptualizations of WBI (endorsing weight bias, weight stigma stereotype awareness, weight stigma experiences), and via measurement-related, demographic, and study-level factors. These findings provide important information that can advance WBI conceptualization and measure-refinement.

Intuitive eating buffers the link between internalized weight stigma and body mass index in stressed adults

Internalized weight stigma (IWS) is independently associated with less intuitive eating (i.e., eating based on endogenous hunger/satiety cues) and higher Body Mass Index (BMI), and intuitive eating training is commonly conceptualized as protective against the effects of IWS on poor behavioral health. The 3-way relationship between IWS, intuitive eating, and BMI has yet to be examined, and it is unclear whether the link between IWS and BMI is buffered by high intuitive eating. This secondary preliminary analysis examined baseline data of stressed adults with poor diet (N = 75, 70% female, 64.1% White, 42.7% with overweight/obesity) in a parent clinical trial that tested the effects of yoga on diet and stress. Validated self-report surveys of IWS and intuitive eating were analyzed with objectively-assessed BMI. Moderated regression analyses using the SPSS PROCESS macro tested whether intuitive eating moderated the IWS-BMI link. The analysis revealed IWS was positively associated with BMI except among people with high intuitive eating. Results extend observational findings linking intuitive eating to lower BMI, and offer preliminary support for the hypothesis that this link may hold even among those with greater IWS. It's possible that individuals with lower BMI and greater IWS may gravitate more towards intuitive eating than those with greater BMI, and/or intuitive eating may be an important target for ameliorating the adverse association of IWS with behavioral and physical health indicators linked to BMI. Continued work is warranted in larger, more generalizable samples using causal and prospective designs.

Internalised weight stigma as a mediator of the relationship between experienced/perceived weight stigma and biopsychosocial outcomes: a systematic review

OBJECTIVE

To systematically review studies that have assessed the mediating role of internalised weight stigma on the relationship between experienced/perceived weight stigma and any biopsychosocial outcomes.

METHODS

PsycINFO, PsycExtra, Web of Science, CINAHL, Medline and Embase were systematically searched. Identified studies were double screened (HB and XPG).

RESULTS

Seventeen studies (across 16 articles) met our inclusion criteria (N = 21,172), and almost all studies measured only psychological outcomes (n = 15). Eight studies found consistent evidence for internalised weight stigma as a mediator of the relationship between experienced/perceived weight stigma and disordered eating outcomes. Preliminary evidence was found for the mediating role of internalised weight stigma on the relationship between experienced/perceived weight stigma and body shame, body dissatisfaction, exercise behaviour, healthcare experiences and behaviours, bodily pain and parental weight talk. However, the findings were inconsistent for depression and anxiety, although only two studies reported these.

CONCLUSION

This review provides preliminary evidence for internalised weight stigma as an intervening variable in the relationship between experienced/perceived weight stigma and adverse health outcomes. Results suggest that there are potential benefits of interventions addressing internalised weight stigma to improve health outcomes. However, these findings must be considered in the context of the psychometric limitations of the Weight Bias Internalisation Scale, which was used in all but one study.

Factors linking perceived discrimination and weight bias internalization to body appreciation and eating pathology: A moderated mediation analysis of self-compassion and psychological distress

Stigma and recurrent discriminatory experiences can lead to distress and internalization of biases. Self-compassion is a widely-recognized resilience factor that may decrease the impact of discrimination on psychological well-being. Research highlights the potential utility of self-compassion in counteracting the harmful effects of discrimination, reducing psychological distress, and preventing the development of eating disorders. The current study examined the roles of self-compassion and psychological distress in perceived discrimination, internalized weight bias, body image, and eating pathology. Participants (N=694) living in the United States completed an online battery of measures assessing perceived discrimination, weight bias internalization, self-compassion, psychological distress, body appreciation, and eating pathology. Self-compassion was associated negatively with perceived discrimination, weight-bias internalization, psychological distress, and eating pathology and was associated positively with body appreciation. Moderated mediation analyses examined whether psychological distress statistically mediated the relationship between perceived discrimination (Model 1) or weight bias internalization (Model 2) on body appreciation, as well as between perceived discrimination (Model 3) or weight bias internalization (Model 4) on eating psychopathology. For all models, self-compassion was explored as a moderator of indirect and direct effects. Results revealed how psychological distress mediated the link between perceived discrimination and body appreciation/eating psychopathology, as well as between weight bias internalization and body appreciation, but not eating psychopathology. For weight bias internalization models only, the statistical links between psychological distress in relation to body appreciation/eating psychopathology were stronger for those with lower self-compassion. Self-compassion may promote more effective coping and outcomes for individuals who are subject to societal stigma.

Adverse Childhood Experiences Associated with Greater Internalization of Weight Stigma in Women with Excess Weight

Adverse childhood experiences (ACEs) may be an early life factor associated with adult weight stigma via biological (e.g., stress response), cognitive (e.g., self-criticism/deprecation), and/or emotional (e.g., shame) mechanisms. This pilot study investigated relationships between ACEs and internalized and experienced weight stigma in adult women with overweight/obesity and explored differential relationships between weight stigma and ACE subtypes (i.e., abuse, neglect, household dysfunction). Adult women (68% white, M age = 33 ± 10 years, M BMI = 33.7 ± 7.2 kg/m2) completed measures of ACEs (ACE Questionnaire), internalized weight stigma (IWS; Weight Bias Internalization Scale-Modified; WBIS-M), and lifetime experiences of weight stigma (yes/no). Data were analyzed with linear and logistic regression (n = 46), adjusting for age, race, and body mass index (BMI). Linear regressions revealed a positive association between ACE and WBIS-M scores (β = 0.40, p = 0.006), which was driven by Abuse-type ACEs (β = 0.48, p = 0.009). Relationships between WBIS-M scores and Neglect- and Household-Dysfunction-type ACEs did not reach significance (β = 0.20, p = 0.173; β = -0.16, p = 0.273). Though descriptive statistics revealed greater rates of experienced weight stigma endorsement by those with high-3+ ACEs (81%) vs. medium-1-2 ACEs (67%) or low/no-0 ACEs (60%), ACE scores were not significantly associated with experienced weight stigma in logistic regression (Wald = 1.36, p = 0.244, OR = 1.324, 95%, CI = 0.825-2.125). ACEs may be an early life factor that increase the risk for internalizing weight stigma in adulthood. Larger studies should confirm this relationship and follow-up on descriptive findings suggesting a potential association between ACEs and experienced weight stigma.

Psychological functioning and well-being before and after bariatric surgery; what is the benefit of being self-compassionate?

Objective

To investigate whether patients’ psychological well‐being (depression, quality of life, body image satisfaction) and functioning (self‐efficacy for eating and exercising behaviours and food cravings) improve 12 months after bariatric surgery and whether self‐compassion is associated with better psychological outcomes and lower weight after bariatric surgery.

Design

Longitudinal, prospective observational study.

Methods

Bariatric patients (n = 126, 77.8% female, 46.4 ± 10.8 years) completed the Self‐compassion Scale, Center for Epidemiology Studies Depression Scale, Impact of Weight on Quality‐of‐Life questionnaire, Body Image Scale, Weight Efficacy Lifestyle Questionnaire, Spinal Cord Injury Exercise Self‐Efficacy Scale, and G‐Food Craving Questionnaire pre‐operatively and 12 months post‐operatively. A medical professional measured patients’ weight during each assessment. Data were analysed using repeated measures t‐tests and multivariate regression analyses with Benjamini–Hochberg correction for multiple testing.

Results

Patients’ BMI, depression, and food cravings decreased significantly after surgery while quality of life, body image satisfaction, and self‐efficacy to exercise improved. Higher self‐compassion was associated with lower post‐operative depression, greater quality of life, higher body image satisfaction, and better self‐efficacy for eating behaviours (p‐values <.05) but not with post‐operative BMI, self‐efficacy to exercise, or food cravings.

Conclusions

Even though pre‐operative self‐compassion was not directly associated with a lower 12‐month post‐operative BMI, it had a positive relationship with patients’ post‐operative well‐being and self‐efficacy for controlling eating behaviour. In turn, this could help patients to manage their health long after bariatric surgery. Further work regarding the role of self‐compassion on long‐term health outcomes would be worthwhile.

Shame and Self-compassion as Risk and Protective Mechanisms of the Internalized Weight Bias and Emotional Eating Link in Individuals Seeking Bariatric Surgery

BACKGROUND

Emotional eating in bariatric surgery patients is inconsistently linked with poor post-operative weight loss and eating behaviors, and much research to date is atheoretical. To examine theory-informed correlates of pre-operative emotional eating, the present cross-sectional analysis examined paths through which experienced weight bias and internalized weight bias (IWB) may associate with emotional eating among individuals seeking bariatric surgery.

METHODS

We examined associations of experienced weight bias, IWB, shame, self-compassion, and emotional eating in patients from a surgical weight loss clinic (N = 229, 82.1% female, M. BMI: 48 ± 9). Participants completed a survey of validated self-report measures that were linked to BMI from the patient medical record. Multiple regression models tested associations between study constructs while PROCESS bootstrapping estimates tested the following hypothesized mediation model: IWB ➔ internalized shame ➔ self-compassion ➔ emotional eating. Primary analyses controlled for adverse childhood experiences (ACE), a common confound in weight bias research. Secondary analyses controlled for depressive/anxiety symptoms from the patient medical record (n = 196).

RESULTS

After covariates and ACE, each construct accounted for significant unique variance in emotional eating. However, experienced weight bias was no longer significant and internalized shame marginal, after controlling for depressive/anxiety symptoms. In a mediation model, IWB was linked to greater emotional eating through heightened internalized shame and low self-compassion, including after controlling for depressive/anxiety symptoms.

CONCLUSIONS

Pre-bariatric surgery, IWB may signal risk of emotional eating, with potential implications for post-operative trajectories. Self-compassion may be a useful treatment target to reduce IWB, internalized shame, and related emotional eating in bariatric surgery patients. Further longitudinal research is needed.
