Disordered eating following bariatric surgery: a review of measurement and conceptual considerations.

Eating disorders are associated with significant medical morbidity and mortality and serious psychological impairment. Individuals seeking bariatric surgery represent a high-risk group for evidencing disordered eating and eating disorders, with some patients experiencing the persistence or onset of disordered eating postsurgery. This review synthesizes the available literature on problematic or disordered eating in the bariatric field, followed by a review of measurement and conceptual considerations related to the use of eating disorder assessment tools within the bariatric population.

The role of body appreciation, weight bias internalization, and disordered eating behaviors among presurgical bariatric patients.

BACKGROUND: Body appreciation and internalized weight bias have consistently been associated with eating behaviors. However, research has yet to examine the role of these variables among presurgical bariatric patients. OBJECTIVES: The present study sought to assess the relationships between body appreciation and weight bias internalization, binge eating, disinhibited eating, and symptoms of depression and anxiety among a sample of presurgical bariatric patients. The study also sought to examine the extent to which body appreciation and weight bias internalization account for unique variance in disordered eating even when controlling for depression and anxiety. SETTING: Academic medical center in the United States. METHODS: Data were collected on body appreciation, weight bias internalization, eating behaviors, depression, and anxiety as part of a standard presurgical psychological evaluation for bariatric surgery (n = 319). Pearson correlations were used to assess relationships between all study variables. Multiple regressions were conducted to assess the roles of body appreciation and weight bias internalization on disordered eating. RESULTS: Significant associations were found between low levels of body appreciation and high levels of weight bias internalization, disordered eating, and symptoms of depression and anxiety. Results indicated that body appreciation and weight bias internalization each significantly accounted for unique variance in symptoms of binge eating and disinhibited eating. Depressive symptoms were also statistically significant in all analyses. CONCLUSION: Findings indicate the importance of conducting future positive body image research, as well as continuing to examine weight-related constructs, such as internalized weight bias, among bariatric surgery patients.

Disinhibition and Subjective Hunger as Mediators Between Weight Bias Internalization and Binge Eating Among Pre-Surgical Bariatric Patients.

PURPOSE: Weight bias internalization, or the process of applying negative weight-related attitudes and beliefs to oneself, is an important construct in regard to patients pursuing bariatric surgery. Weight bias internalization (or internalized weight bias) has been previously associated with depressive symptoms and binge eating among pre-surgical bariatric patients. However, a gap in the literature exists pertaining to how certain eating behaviors may mediate the relationship between weight bias internalization and binge eating. The present study assessed the role of eating behaviors (i.e., cognitive restraint, disinhibition, and hunger) as mediators between weight bias internalization and binge eating symptoms when controlling for depression. MATERIALS AND METHODS: A total of 708 adults (Mage = 42.91; White = 95.3%; women = 79.4%) seeking bariatric surgery at a tertiary academic medical center in the Appalachia region of the USA were included in this retrospective study. Patients completed validated measures of weight bias internalization, eating behaviors, and depression as part of a routine, psychological evaluation in order to determine surgical clearance. RESULTS: Disinhibition and hunger were significant mediators in the relationship between weight bias internalization and binge eating beyond the role of depressive symptoms alone. CONCLUSION: Disinhibited eating, or the tendency to experience a loss of control and eating in response to negative emotions, as well as subjective feelings of hunger are important dimensions of eating, particularly as related to weight bias internalization and binge eating. Weight bias internalization is an important factor to consider among pre-surgical bariatric patients and warrants additional treatment considerations.

Sexual minority bariatric patients: preliminary examination of eating behaviors, anxiety, and depression.

BACKGROUND: Disparities in obesity care and bariatric surgery persist among patients of diverse identities. However, little is known about sexual minority (SM) bariatric patients. OBJECTIVES: This study sought to describe, in a preliminary fashion, sexual orientation variables of outness, self-esteem, and perceived discrimination among a sample of SM patients pursuing bariatric surgery. The study also sought to compare SM and heterosexual bariatric candidates on measures of eating behaviors, anxiety, and depression. SETTING: Academic medical center in the United States. METHODS: Data were collected as part of a standard psychological evaluation for surgical clearance between May 1, 2018 and December 31, 2019. Data included demographic characteristics, sexual orientation variables, eating behaviors, anxiety, and depression. Descriptive statistics were included to present findings among SM patients. One-way analyses of covariance were conducted to assess differences between SM and heterosexual patients. RESULTS: A total of 633 patients were evaluated (38 SM and 595 heterosexual). SM patients had high outness scores with high self-esteem and minimal perceived discrimination. SM patients endorsed lower cognitive restraint, higher disinhibition, and increased hunger compared with heterosexual patients (P < .05). SM patients also reported significantly more symptoms of anxiety and depression compared with heterosexual patients (P < .05). CONCLUSIONS: Findings provide preliminary evidence toward the importance of assessing for sexual orientation among bariatric patients. Future research is warranted to assess the unique role of sexual orientation, as well as explore causal links between sexual orientation, eating behaviors, and mental health among bariatric patients pre- and post surgery.

Psychological Diagnoses and Weight Loss among Appalachian Bariatric Surgery Patients.

Background: The relationship between presurgical psychopathology and weight loss following bariatric surgery is complex; previous research has yielded mixed results. The current study investigates the relationship among presurgical mental health diagnoses, symptom severity, and weight loss outcomes in an Appalachian population, where obesity-related comorbidities are prominent. Methods: A retrospective chart review was performed on bariatric surgery patients in an accredited Appalachian centered academic hospital in northern West Virginia between 2013 and 2015 (n = 347). Data extraction included basic demographics, anthropometrics (percent excess weight loss (%EWL)) at six-month, one-year, and two-year postoperative visits, and two validated psychological questionnaires (Beck Depression Inventory (BDI-II) and Beck Anxiety Inventory (BAI)) from patient's presurgical psychological evaluation. Results: Average patient population was 92.5% Caucasian, 81.5% female, 45 ± 11.5 years old, and 84.1% who underwent laparoscopic Roux-en-Y gastric bypass surgery with the remaining having laparoscopic sleeve gastrectomy. At baseline, no differences were detected in weight, excess body weight, or body mass index between surgery types. Average baseline BDI-II score was 10.1 ± 8.68 (range 0-41) and BAI score was 6.1 ± 6.7 (range 0-36), and this was not significantly different by surgery at baseline. Both baseline psychological scores were in the "minimal" severity range. BDI-II was positively related to BMI of patients at baseline (p = 0.01). Both BDI-II and BAI were not significantly related to %EWL across follow-up. Conclusion: Other than baseline weight, BDI-II and BAI scores were not related to %EWL outcomes in patients receiving bariatric surgery in the Appalachian region. Future work should examine mixed methods approaches to capture prospective and longitudinal data to more thoroughly delve into mental health aspects of our Appalachian patients and improve efforts to recapture postoperative patients who may have been lost to follow-up.

Psychometric properties of NIH PROMIS® instruments in bariatric surgery candidates.

OBJECTIVE: Ascertain the psychometric properties of the Patient-Reported Outcomes Measurement Information System® (PROMIS®) Depression (PROMIS-D®) and Anxiety (PROMIS-A®) Short Forms in a sample of presurgical bariatric patients. METHOD: This retrospective chart review included 259 patients who completed a presurgical psychological evaluation comprising a semistructured interview and self-report measures. Other data used included demographics, psychiatric diagnoses, and initial psychological clearance for surgery (yes/no). Reliability of the PROMIS-D® and PROMIS-A® instruments was assessed using Cronbach's alpha, interitem correlations, and item-total correlations. Convergent, predictive, and concurrent validity were assessed using various methods (correlations, logistic regressions, and generalized linear models) to determine whether PROMIS® instruments were correlated with similar measures, predicted surgical clearance and psychiatric diagnosis, and whether psychiatric diagnosis status was associated with significantly different PROMIS® scores. Categorical confirmatory factor analyses assessed the factor structure, and multiple-indicator multiple cause models assessed invariance. RESULTS: Patients were predominantly female (78%), white (97%) and middle-aged (M = 43.49, SD = 11.26). Rates of diagnosed anxiety and depression-related disorders were high (17% and 23%). At least 65% of respondents reported "never" or "rarely" experiencing symptoms across both measures, and the mean T scores for the PROMIS-A® and PROMIS-D® were 48.31 (SD = 8.99) and 48.64 (SD = 9.49), respectively. Both measures demonstrated good psychometric properties and were essentially unidimensional. CONCLUSIONS: Analyses supported using both PROMIS® measures. Additionally, two subgroups were identified: those who reported virtually no symptoms of anxiety or depression, likely because they want surgical approval, and those not receiving initial psychological clearance for surgery based on PROMIS® self-reported scores indicating distress and clinician-diagnosed psychopathology.

Problematic Eating Behaviors and Eating Disorders Associated with Bariatric Surgery.

Bariatric surgery candidates often report problematic and/or eating disordered behaviors. For most patients, these eating behaviors improve after surgery. A subset, however, experience a recurrence or new onset of problematic eating behaviors as early as 2 months to 18 months after surgery, which can result in compromised weight loss/excessive weight regain. Those most at risk are individuals with comorbid psychopathology (ie, loss-of-control eating or depression) after surgery. For some, such problems are present before surgery. Therefore, it is critical to monitor patients closely after surgery so that appropriate psychiatric treatments can be provided if indicated.

Bariatric Surgery Outcomes in Appalachia Influenced by Surgery Type, Diabetes, and Depression.

BACKGROUND: Most effective treatment for morbid obesity and its comorbidities is bariatric surgery. However, research is limited on weight loss and associated outcomes among patients in Appalachia. The objective of this study was to examine demographic and comorbidity influence on surgical outcomes of this population including age, sex, race, state of residence, education, marital status, body mass index (BMI kg/m2), excess body weight (EBW), percent excess weight loss (%EWL), blood pressure, diagnosed depression, diagnosed type 2 diabetes (T2D), Beck Depression Inventory-II (BDI-II), and laboratory values (i.e., hemoglobin A1c). METHODS: A retrospective electronic medical record (EMR) data extraction was performed on N = 582 patients receiving bariatric surgery (laparoscopic Roux-en-Y gastric bypass [RYGB] and laparoscopic sleeve gastrectomy [SG]) between 10/2013 and 2/2017. RESULTS: Patient population was 92.5% Caucasian, 79.3% female, 62.8% married, 45 ± 11.1 years, 75.8% received RYGB, and 24.2% received SG. Average %EWL from baseline to 1-year follow-up was 68.5 ± 18.4% (n = 224). In final descriptive models, surgery type, diagnosed T2D, HbA1c, and depressive symptoms were significant covariates associated with lower %EWL. CONCLUSIONS: Findings suggest patients completing surgery within an Appalachian region have successful surgical outcomes at 1-year post-surgery, as indicated by significant reductions of > 50% EWL, regardless of other covariates. Results suggest that bariatric programs should consider paying special consideration to patients with T2D or depressive symptoms to improve outcomes. Results have potential to inform future prospective studies and aid in guiding specific interventions tailored to address needs of this unique population.

Predictors of Preoperative Program Non-Completion in Adolescents Referred for Bariatric Surgery.

BACKGROUND: Factors contributing to adolescents' non-completion of bariatric surgery, defined as self-withdrawal during the preoperative phase of care, independent of program or insurance denial, are largely unknown. Recent adolescent and adult bariatric surgery literature indicate that psychological factors and treatment withdrawal play a role; however, for adolescents, additional age-salient (family/caregiver) variables might also influence progression to surgery. OBJECTIVES: The present study examined demographic, psychological, and family/caregiver variables as predictors of whether adolescents completed surgery ("completers") or withdrew from treatment ("non-completers"). SETTING: Adolescents were from a bariatric surgery program within a pediatric tertiary care hospital. METHODS: A retrospective chart review was conducted of consecutive patients who completed bariatric surgery psychological intake evaluations from September 2009 to April 2013. Data involving completer (n = 61) versus non-completer (n = 65) status were analyzed using two-tailed independent t tests, Chi-squared tests, and logistic regressions. RESULTS: Forty-three percent of adolescents completed surgery, similar to adult bariatric samples. Significantly more males were non-completers (p < .05), and there was a trend towards non-completion for older adolescents (p = 0.06). No other demographic, psychological, or caregiver/family variables were significant predictors of non-completion. CONCLUSIONS: These findings indicate that demographic variables, rather than psychological or family factors, were associated with the progression to or withdrawal from surgery. Further assessment is needed to determine specific reasons for completing or withdrawing from treatment, particularly for males and older adolescents, to improve clinical care and reduce attrition.

Predictors of Binge Eating among Bariatric Surgery Candidates: Disinhibition as a Mediator of the Relationship Between Depressive Symptoms and Binge Eating.

BACKGROUND: Current and lifetime psychopathology is common in adult patients seeking bariatric surgery, with major depressive disorder and binge eating disorder affecting a higher proportion of this group than the general population. While depressive symptoms have been previously associated with eating pathology, potential mediators of this relationship are not well understood. METHODS: This study used a naturalistic, retrospective design to investigate cognitive and behavioral aspects of eating behavior (cognitive restraint, disinhibition, and hunger) as potential mediators of the relationship between depressive symptoms and binge eating within a sample of 119 adult patients (82.4% female; 96.6% white; mean age = 47 years) seeking bariatric surgery (Roux-en-Y and sleeve gastrectomy) at a large university medical center. Patients completed a standardized presurgical psychological evaluation to determine appropriateness for bariatric surgery as part of routine clinical practice. Binge eating was assessed via clinician rating (number of binge eating episodes per week) based on DSM-IV diagnostic criteria and self-report measures (Binge Eating Scale) in order to account for potential methodological differences. Depressive symptoms were assessed using the Beck Depression Inventory. RESULTS: Depressive symptoms were a significant predictor of binge eating, disinhibition, and hunger. However, only disinhibition emerged as a significant mediator of the relationship between depressive symptoms and binge eating. CONCLUSIONS: Behavioral disinhibition, or a tendency toward overconsumption of food and challenges restraining impulses associated with a loss of control eating, may represent an important variable in determining the relation between depressive symptoms and binge eating, in bariatric surgery patients.

A multisite view of psychosocial risks in patients presenting for bariatric surgery.

OBJECTIVE: The psychosocial health of adolescents with severe obesity (BMI ≥ 120% for age and gender) has only recently been the focus of empirical work. METHODS: This multisite study-an ancillary to a prospective longitudinal observational study documenting health in adolescents having weight loss surgery (WLS)-presents preoperative/baseline data from 141 WLS adolescents and 83 nonsurgical comparisons (NSComps). Self-report data from adolescent and caregiver dyads characterize adolescent psychopathology and potential correlates. RESULTS: One in three adolescents reported internalizing symptoms, and one in five endorsed externalizing symptoms in the clinical range. Generalized linear model analysis demonstrated that increased risk of psychopathology for adolescents with severe obesity was associated with family dysfunction, eating pathology, family composition, and seeking behavioral intervention (versus WLS), whereas better quality of life (QOL) was associated with lower psychopathology. CONCLUSIONS: While psychopathology rates are comparable to national samples, there is a subgroup of youth who present for behavioral weight loss services and are at greater risk for psychopathology relative to national adolescent base rates. Adolescents who achieve candidacy for WLS may be a highly selective population of youth with severe obesity and may have lower base rates of psychopathology compared to NSComps.

Longitudinal trends in food cravings following Roux-en-Y gastric bypass in an adolescent sample.

BACKGROUND: Food cravings are more prevalent and potentially problematic for many individuals with obesity. Initial evidence suggests that bariatric surgery has some short-term beneficial effects on cravings in adults, but little is known about the effect on adolescents or the trajectory beyond 6 months. METHODS: The purpose of the present study was to determine the longitudinal effect of Roux-en-Y gastric bypass (RYGB) on food cravings in a sample of adolescents with severe obesity (body mass index (BMI)≥40 kg/m2). Sixteen adolescents were recruited and underwent RYGB. Participants completed the Food Craving Inventory before RYGB, and 3, 6, 12, 18, and 24 months postoperatively. The present study took place in a single pediatric tertiary care hospital. RESULTS: RYGB produced a negative (cravings decreased as time increased) nonlinear trend for total food cravings as well as for each individual subscale (sweets, high fat foods, carbohydrates, fast food) over the 24-month study period. This means that while cravings decrease postsurgically, there is a decline in the slope with the line reaching asymptote at approximately 18 months. BMI change was not a significant predictor of food cravings, but low statistical power may account for this lack of significance. CONCLUSION: These findings provide preliminary evidence that RYGB decreases food cravings in adolescents.
