Psychopathology, disordered eating, and impulsivity in patients seeking bariatric surgery.

ABSTRACT:

Background

Most patients who undergo bariatric surgery experience significant weight loss and improvements in obesity-related co-morbidities in the first 6-18 months after surgery. However, 20%-30% of patients experience suboptimal weight loss or significant weight regain within the first few postoperative years. Psychosocial functioning may contribute to suboptimal weight loss and/or postoperative psychosocial distress.

Objective

Assess psychosocial functioning, eating behavior, and impulsivity in patients seeking bariatric surgery.

Setting

Two university hospitals.

Methods

Validated interviews and questionnaires. Impulsivity assessed via computer program.

Results

The present study included a larger (n = 300) and more racially diverse (70% non-White) sample than previous studies of these relationships. Forty-eight percent of participants had a current psychiatric diagnosis and 78% had at least 1 lifetime diagnosis. Anxiety disorders were the most common current diagnosis (25%); major depressive disorder was the most common lifetime diagnosis (44%). Approximately 6% of participants had a current alcohol or substance use disorder; 7% had a positive drug screen before surgery. A current psychiatric diagnosis was associated with greater symptoms of food addiction and night eating. Current diagnosis of alcohol use disorder or a lifetime diagnosis of anxiety disorders was associated with higher delay discounting.

Conclusion

The study identified high rates of psychopathology and related symptoms among a large, diverse sample of bariatric surgery candidates. Psychopathology was associated with symptoms of disordered eating and higher rates of delay discounting, suggesting impulse control issues.

Contributions of Emotional Overload, Emotion Dysregulation, and Impulsivity to Eating Patterns in Obese Patients with Binge Eating Disorder and Seeking Bariatric Surgery.

Project description:BACKGROUND:Binge eating disorder (BED) is very frequently observed in patients considered for weight loss surgery and seems to influence their outcome critically. Literature highlights a global emotional overload in individuals with BED, but little is known on the mechanisms involved. The present study aimed to focus on emotion regulation, impulsivity, depression, and anxiety in people with and without BED and fulfilling inclusion criteria for bariatric surgery. Doing so, we sought to individualize factors related to BED. Then, we examined the contribution of depression, anxiety, emotion regulation difficulties, and impulsivity to inappropriate eating behaviors observed in patients with BED. METHODS:A sample of 121 individuals (79.3% female, mean age: 40.82 ± 9.26, mean current body mass index (BMI): 44.92 kg/m2 ± 7.55) seeking bariatric surgery were recruited at the Champagne Ardenne Specialized Center in Obesity in Reims, France from November 2017 to October 2018. They were stratified as with or without BED according to the binge eating scale. Characteristics identified in univariate analyses as differentiating the two groups were then included in multivariable analyses. RESULTS:Multivariable analyses showed that limited access to emotional regulation strategies was significantly associated with BED. Furthermore, inappropriate eating behaviors were independently associated with age, depression severity, anxiety, emotional dysregulation, and impulsivity in BED group. CONCLUSIONS:The present findings are indicative of an association between emotion deficit and BED in obese patients seeking bariatric surgery. Patients with BED could benefit from the addition of an emotion regulation intervention.

Language Matters: Patients' Preferred Terms for Discussing Obesity and Disordered Eating with Health Care Providers After Bariatric Surgery.

Project description:ObjectivePatients who seek or undergo bariatric surgery are likely to experience pervasive societal biases regarding weight and eating behaviors in the health care system. This cross-sectional study examined patient preferences for desired weight- and eating-related terms for health care providers among individuals with loss-of-control eating after bariatric surgery.MethodsA total of 114 of 140 adults who underwent bariatric surgery approximately 1.5 years prior and were in the follow-up stage of a controlled treatment trial testing behavioral treatments completed language preference measures.ResultsOf the 11 terms used to describe weight, only 2 were viewed neutrally, weight and BMI. All other terms, including obesity, were rated negatively, and many were rated extremely negatively. Fatness was the least desirable term. Of the 18 terms used to describe loss-of-control eating, one ("ate until uncomfortably full") was rated positively, and several were rated neutrally. On average, none of the weight or loss-of-control eating terms was rated as "desirable" or "very desirable." Analyses revealed few gender and racial differences in language preferences.ConclusionsMany weight-related and loss-of-control eating terms are viewed as undesirable. Health care providers should begin with neutrally rated terms and ask patients about their language preferences when speaking with individuals before/after bariatric surgery to improve patient-centered care and reduce perceived weight bias.

Core psychopathology of treatment-seeking patients with binge-eating disorder: a network analysis investigation.

Project description:BACKGROUND:Mental disorders may emerge as the result of interactions between observable symptoms. Such interactions can be analyzed using network analysis. Several recent studies have used network analysis to examine eating disorders, indicating a core role of overvaluation of weight and shape. However, no studies to date have applied network models to binge-eating disorder (BED), the most prevalent eating disorder. METHODS:We constructed a cross-sectional graphical LASSO network in a sample of 788 individuals with BED. Symptoms were assessed using the Eating Disorders Examination Interview. We identified core symptoms of BED using expected influence centrality. RESULTS:Overvaluation of shape emerged as the symptom with the highest centrality. Dissatisfaction with weight and overvaluation of weight also emerged as highly central symptoms. On the other hand, behavioral symptoms such as binge eating, eating in secret, and dietary restraint/restriction were less central. The network was stable, allowing for reliable interpretations (centrality stability coefficient = 0.74). CONCLUSIONS:Overvaluation of shape and weight emerged as core symptoms of BED. This trend is consistent with past network analyses of eating disorders more broadly, as well as literature that suggests a primary role of shape and weight concerns in BED. Although DSM-5 diagnostic criteria for BED does not currently include a cognitive criterion related to body image or shape/weight overvaluation, our results provide support for including shape/weight overvaluation as a diagnostic specifier.

Eating behaviors and weight outcomes in bariatric surgery patients amidst COVID-19.

Project description:BackgroundRecent studies suggest that eating habits are an area particularly affected by the lockdown imposed by many countries to curb the COVID-19 epidemic. Individuals that received bariatric surgery may represent a particularly susceptible population to the adverse effects of lockdown for its potential impact on eating, psychological, and weight loss outcomes.ObjectivesThis study seeks to investigate the incremental impact of COVID-19 lockdown on treatment outcomes of postbariatric patients in the risk period for weight regain.SettingMain hospital center.MethodsThis work uses data from an ongoing longitudinal study of bariatric patients assessed before surgery (T0), 1.5 years after sugery (T1), and 3 years after surgery (T2). Two independent groups were compared: the COVID-19_Group (n = 35) where T0 and T1 assessments were conducted before the pandemic started and T2 assessment was conducted at the end of the mandatory COVID-19 lockdown; and the NonCOVID-19_Group (n = 66), covering patients who completed T0, T1, and T2 assessments before the epidemic began. Assessment included self-report measures for disordered eating, negative urgency, depression, anxiety, stress, and weight outcomes.ResultsGeneral linear models for repeated measures showed that the COVID-19_Group presented significantly higher weight concern (F = 8.403, P = .005, ƞ2p = .094), grazing behavior (F = 7.166, P = .009, ƞ2p = .076), and negative urgency (F = 4.522, P = .036, ƞ2p = .05) than the NonCOVID-19_Group. The COVID-19_Group also showed less total weight loss (F = 4.029, P = .05, ƞ2p = .04) and larger weight regain at T2, with more COVID-19_Group participants experiencing excessive weight regain (20% versus 4.5%).ConclusionThese results show evidence for the impact of the coronavirus outbreak on eating-related psychopathology and weight outcomes in postbariatric surgery patients.

Loss of control eating and eating disorders in adolescents before bariatric surgery.

Project description:OBJECTIVE:This study assessed loss of control (LOC) eating and eating disorders (EDs) in adolescents undergoing bariatric surgery for severe obesity. METHOD:Preoperative baseline data from the Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) multisite observational study (n?=?242; median BMI?=?51 kg/m2 ; mean age= 17; 76% female adolescents; 72% Caucasian) included anthropometric and self-report questionnaires, including the Questionnaire of Eating and Weight Patterns-Revised (QEWP-R), the Night Eating Questionnaire (NEQ), the Beck Depression Inventory (BDI-II), and the Impact of Weight on Quality of Life-Kids (IWQOL-Kids) RESULTS: LOC eating (27%) was common and ED diagnoses included binge-eating disorder (7%), night eating syndrome (5%), and bulimia nervosa (1%). Compared to those without LOC eating, those with LOC eating reported greater depressive symptomatology and greater impairment in weight-related quality of life. DISCUSSION:Before undergoing bariatric surgery, adolescents with severe obesity present with problematic disordered eating behaviors and meet diagnostic criteria for EDs. LOC eating, in particular, was associated with several negative psychosocial factors. Findings highlight targets for assessment and intervention in adolescents before bariatric surgery. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:947-952).

Eating Habits of Children Born after Maternal Bariatric Surgery.

Project description:Mothers who underwent bariatric surgery (BS) before pregnancy have worrisome eating habits, but little is known about the eating habits of their offspring. EFFECTOR is a cross-sectional, long-term follow-up study of 4-11-year-old children born from mothers that underwent bariatric surgery before pregnancy (n = 36), mothers with overweight/obesity (OW/OB) in a control group (n = 71), and mothers with a normal weight (NW) in a second control group (n = 35). Data on anthropometry and on eating habits obtained through a Food Frequency Questionnaire were collected prospectively. The children's body mass index (BMI) scores significantly correlated with maternal pre-pregnancy BMI. The prevalence of overweight and obesity was the highest in children of the BS group (38.9% vs. 15.5% for children of the OW/OB group and 5.7% for those of the NW group; p = 0.004). Meal-skipping behavior was comparable between the groups. There was no difference in fruit and vegetable consumption. The BS group consumed more low-calorie sweetened beverages compared to the NW group (p = 0.01) but less fruit juice compared to the NW and OW/OB groups (p = 0.01). Our results may indicate a sugar-avoiding behavior in children of the BS group, fitting dietary maternal habits in a strategy to prevent dumping syndrome. In conclusion, maternal pre-pregnancy bariatric surgery does not alter unhealthy eating behaviors and the risk of development of overweight during childhood in their children.

Psychological correlates to dysfunctional eating patterns among morbidly obese patients accepted for bariatric surgery.

Project description:OBJECTIVE:To examine the relationships between dysfunctional eating patterns, personality, anxiety and depression in morbidly obese patients accepted for bariatric surgery. DESIGN:The study used cross-sectional data collected by running a randomized controlled trial (http://clinicaltrials.gov/ct2/show/NCT01403558). SUBJECTS:A total of 102 patients (69 women, 33 men) with a mean (SD) age of 42.6 (9.8) years and a mean BMI of 43.5 (4.4) kg/m(2) participated. MEASUREMENTS:Measurements included the NEO-PI-R (personality: neuroticism, extroversion, openness, conscientiousness and agreeableness), the TFEQ-R-21 (dysfunctional eating: emotional eating (EE), uncontrolled eating (UE) and cognitive restraint of eating (CR)) and the HADS (anxiety and depression). RESULTS:The personality traits neuroticism and conscientiousness were more strongly correlated with dysfunctional eating than anxiety and depression. These differences were most pronounced for emotional and cognitive restraint of eating. Emotional eating occurred more often in female than in male patients, a finding that was partially mediated by neuroticism but not by anxiety and depression. CONCLUSION:Personality traits may be important to address in the clinical management of morbidly obese patients seeking bariatric surgery as neuroticism is particularly salient in female patients displaying an emotional eating behaviour.

The relationship between childhood maltreatment and psychopathology in adults undergoing bariatric surgery.

Project description:BackgroundA history of childhood maltreatment and psychopathology are common in adults with obesity.ObjectivesTo report childhood maltreatment and to evaluate associations between severity and type of childhood maltreatment and lifetime history of psychopathology among adults with severe obesity awaiting bariatric surgery.SettingFour clinical centers of the Longitudinal Assessment of Bariatric Surgery Research Consortium.MethodsThe Childhood Trauma Questionnaire, which assesses presence/severity (i.e., none, mild, moderate, severe) of physical abuse, mental abuse, physical neglect, mental neglect, and sexual abuse, was completed by 302 female and 66 male bariatric surgery patients. Presurgery lifetime history of psychopathology and suicidal ideation/behavior were assessed with the Structured Clinical Interview for DSM-IV and the Suicidal Behavioral Questionnaire-Revised, respectively. Presurgery lifetime history of antidepressant use was self-reported.ResultsTwo thirds (66.6%) of females and 47.0% of males reported at least 1 form of childhood trauma; 42.4% and 24.2%, respectively, at greater than or equal to moderate severity. Among women, presence/greater severity of childhood mental or physical abuse or neglect was associated with a higher risk of history of psychopathology (i.e., major depressive disorder, posttraumatic stress disorder, other anxiety disorder, alcohol use disorder, binge eating disorder), suicidal ideation/behavior and antidepressant use (P for all ≤ .02). These associations were independent of age, race, education, body mass index, and childhood sexual abuse. Childhood sexual abuse was independently associated with a history of suicidal ideation/behavior and antidepressant use only (P for both ≤ .05). Statistical power was limited to evaluate these associations among men.ConclusionAmong women with obesity, presence/severity of childhood trauma was positively associated with relatively common psychiatric disorders.
