Sleep and aberrant eating behaviors in metabolic/bariatric presurgical candidates.

BACKGROUND: Metabolic/bariatric surgery (MBS) is the most effective treatment for obesity, yet many factors influence successful individual weight loss. Among those are a variety of health behaviors that are assessed in the process of presurgical psychological evaluations, including eating pathology and sleep disturbance (both of which are relatively common among surgical candidates). OBJECTIVES: This study aims to examine the relationship between sleep, binge eating, and night eating behaviors among individuals seeking MBS. SETTING: Medical center and private psychological practice in Mississippi. METHODS: Patients (N = 311) seeking presurgical psychological evaluations for bariatric surgery completed self-report measures. Of these, 83.0% were females and 70.7% of those with ethnicity data identified as White. Average body mass index (BMI) in the sample was 46.5 (standard deviation [SD] = 8.02). Correlations between variables were calculated and examination of the indirect effect of sleep disturbance on night eating as mediated by binge eating was conducted. RESULTS: Sleep disturbance, binge eating, and night eating were significantly associated (b = .22-.45). Mediation analysis yielded a significant indirect effect, indicating that binge eating propensity explains the relationship between impaired sleep and night eating symptoms (b = .09, standard error [SE] = .03, confidence interval [CI]: .04-.18). CONCLUSIONS: The observed relationship between sleep disturbance, night eating, and binge eating among bariatric candidates provides implications for future research and treatment approaches. Specifically, additional attention to sleep disturbance in the presurgical assessment process and consideration of sleep hygiene as a potential target for intervention may facilitate improvements in overall health, adjustment, and sustained weight loss.

Sedentary behavior and food cravings in diverse overweight women: a pilot study.

UNLABELLED: Obesity rates have risen sharply in the United States, with minority women among those most affected. Although a majority of Americans are considered inactive, little attention has been devoted to studying the correlation of sedentary behavior with dietary cravings in adults. OBJECTIVE: The current study used objective and self-report methods to measure sedentary behavior and its relationship to food cravings in a sample of overweight African American and Caucasian women. DESIGN: Thirty-nine adult women (54% African American) with an average body mass index of 33.7 wore accelerometers for one week and completed self-report measures of sedentary behavior, physical activity, and food cravings. RESULTS: Self-reported television viewing time was slightly longer (3.0 versus 2.5 hours), although total sedentary time was shorter (6.7 versus 8.0 hours) on weekends versus weekdays. Weekend but not weekday sedentary time and television viewing were associated with stable aspects of food cravings rather than craving for specific foods. CONCLUSION: In this small sample, only a third of all sedentary time was attributed to viewing television. Assessing whether sedentary behavior occurs by necessity versus choice may be a factor to consider in examining its relationship to food cravings.

Distress Tolerance and Psychological Comorbidity in Patients Seeking Bariatric Surgery.

INTRODUCTION/PURPOSE: Distress intolerance is characterized by a low threshold for negative emotional experiences and lack of emotion regulation and has been shown to predict various health outcomes. As such, the primary aim of this study was to determine the association between distress tolerance and psychological variables (eating behaviors, mood, substance use, trauma history), completion of bariatric surgery, and post-bariatric surgery weight loss outcomes and follow up with a provider. MATERIALS AND METHODS: Two hundred forty-eight patients (75 % female, 89 % Caucasian) underwent a multidisciplinary evaluation for bariatric surgery and were assessed for psychiatric disorders via semi-structured clinical interview and psychometric questionnaires. RESULTS: Low distress tolerance was associated with symptoms of depression (p ≤ 0.001), anxiety (p ≤ 0.001), disordered eating behaviors (p ≤ 0.001), substance abuse (p ≤ 0.001), a history of being the victim of childhood sexual abuse (p ≤ 0.001), and with high BMI (p < .05). Patients endorsing higher levels of distress tolerance were more likely to undergo bariatric surgery (p < .01). Distress tolerance was not related to 2-year post-surgical weight loss outcomes or follow up with a provider. CONCLUSION: The ability to tolerate negative affect may be a variable that differentiates which patients undergo bariatric surgery rather than early postoperative outcomes.

Stop regain: a pilot psychological intervention for bariatric patients experiencing weight regain.

BACKGROUND: A subset of bariatric patients fails to achieve or maintain long-term successful weight loss. Psychological and behavioral factors contributing to poor long-term outcomes include decreased adherence to surgical eating guidelines, life stressors that derail weight maintenance, unhealthy eating patterns, and substance use. OBJECTIVES: A 6-week pilot group behavioral intervention utilizing techniques of cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) was developed to treat bariatric patients experiencing weight regain. SETTING: Patients were treated at a large Midwestern academic medical center. METHODS: Twenty-eight patients (93% female, 100% Caucasian) with a mean age of 53 and a mean BMI of 35.6 had regained an average of 17 kg or 37% of the weight lost after initially successful Roux-en-Y gastric bypass (RYGB). All patients completed the Structured Clinical Interview for DSM-IV-TR (SCID I) modules assessing mood and substance dependence, and completed a series of questionnaires before and after group treatment, with weekly assessment of depressive symptoms, binge eating, and alcohol use. Results were analyzed utilizing repeated measures ANOVA. RESULTS: Weight decreased during the intervention by an average of 1.6 ± 2.38 kg (p ≤ 0.01). Level of depressive symptoms improved for treatment completers (p ≤ 0.01). Food records indicated that grazing patterns decreased (p ≤ 0.01) and subjective binge eating episodes decreased (p ≤ 0.03). CONCLUSIONS: A 6-week pilot group behavioral intervention demonstrated an ability to help patients reverse their pattern of weight regain. Tailored behavioral interventions may be a useful treatment to enhance maintenance of long-term weight loss.

Which facets of mindfulness are related to problematic eating among patients seeking bariatric surgery?

There has been growing research indicating the potential positive benefits of mindfulness-based interventions for obesity, but few studies have examined the relationship of mindfulness processes to obesity-related behaviors, particularly among clinical populations such as bariatric surgery candidates. The current study examined the relationship of specific mindfulness facets to a variety of problematic eating behaviors assessed through diagnostic interviews in a clinical sample of 820 patients seeking bariatric surgery. Results indicated that greater mindfulness on specific facets, particularly acting with awareness, was related to less binge and emotional eating. Greater mindfulness was also related, though less consistently, to less habitual overeating and grazing. The observing facet was generally unrelated to problematic eating, but in a few cases being more observant related to having greater eating problems. The results of the study and future directions are discussed in relation to research on problematic eating in obesity and mindfulness-based interventions.

Bipolar disorder symptoms in patients seeking bariatric surgery.

BACKGROUND: Mood disorders are common among patients seeking bariatric surgery although little data exist regarding the prevalence of bipolar symptoms in this population and how they influence surgical outcomes. Our aim was to describe baseline rates of bipolar symptoms and their relationship to psychological factors and completing surgery in a sample of adults seeking bariatric surgery at an academic medical center. METHODS: We retrospectively reviewed the relationship of bipolar symptoms to demographic characteristics, baseline weight, psychological factors, and bariatric surgery completion. RESULTS: Nine hundred thirty-five patients completed the preoperative psychological evaluation. Six percent of the preoperative sample screened positive for symptoms of bipolar disorder. Patients with bipolar symptoms endorsed more robust psychopathology, trauma history, and problematic eating behaviors than patients without bipolar symptoms. Twenty-two percent of the patients with bipolar symptoms underwent bariatric surgery (n = 12), yet only 13 % were denied bariatric surgery for psychiatric reasons, suggesting that other variables may influence the completion of bariatric surgery for these patients. CONCLUSION: Prevalence rates of bipolar symptoms may be greater in patients seeking bariatric surgery compared with the general population, and few patients with bipolar symptoms actually undergo bariatric surgery. Psychological factors differentiate patients with bipolar symptoms who undergo bariatric surgery vs those who do not.

Race, weight, and correlates of binge eating in female college students.

This study examined the correlates of race, weight status, and binge eating among 715 female undergraduate students (77% Caucasian; 13% African American) enrolled at an urban university. Approximately 21.7% of Caucasians and 36.8% of African-Americans (AA) were overweight/obese. Higher BMI was associated with BED, and severity of binge eating symptoms. After removing participants who endorsed compensatory behaviors ≥ 1×/week from the analyses, 8.4% of the sample met criteria for BED (2.4% of the AA and 9.9% of the Caucasian students) and 44% reported severe binge eating symptoms. AA students were less likely to have BED than Caucasian students and reported less severe binge eating symptomatology. For Caucasian students, mood, cognitive restraint, drive for thinness, and BMI all contributed significant individual variance in binge eating severity. For African Americans, mood, body image dissatisfaction, and drive for thinness were found to be unique contributors. For those meeting criteria for BED, retrospectively recalled predictors of binge eating included negative affect (e.g., self-anger, worry, guilt), but not hunger. Behavioral triggers for binge behavior differed by race, as well, with African American students retrospectively reporting lower levels of anxiety prior to bingeing. Results from this study suggest that there are racial differences in binge eating behaviors. Future studies are needed to examine differences in eating practices among racial groups (e.g., grazing, large portions, high fat food preparation) that may contribute to early onset weight gain and obesity. The results suggest the importance of sensitive tailored weight and disordered eating interventions for college women from diverse backgrounds.

Identification and treatment of eating disorders in the primary care setting.

Eating disorders, which are associated with a host of adverse medical morbidities, negative psychological sequelae, and considerable reductions in quality of life, should be diagnosed and treated promptly. However, primary care physicians may find it uniquely challenging to detect eating disorders in their early stages, before obvious physical problems arise and while psychological symptoms are subtle. Although psychological symptoms may dominate the presentation, the physician is an integral member of the treatment team and is in a unique role to diagnose and treat eating disorders. This clinical review surveys the eating disorders literature, identified by searching MEDLINE and PubMed for articles published from January 1, 1983, to September 30, 2009, using the following keywords: anorexia nervosa, bulimia nervosa, eating disorders, eating disorders NOS, binge eating, binge eating disorder, and night eating syndrome. This review also focuses on practical issues faced by primary care physicians in the management of these conditions and other issues central to the care of these complex patients with medical and psychiatric comorbid conditions.

Fat stigmatization in television shows and movies: a content analysis.

OBJECTIVE: To examine the phenomenon of fat stigmatization messages presented in television shows and movies, a content analysis was used to quantify and categorize fat-specific commentary and humor. RESEARCH METHODS AND PROCEDURES: Fat stigmatization vignettes were identified using a targeted sampling procedure, and 135 scenes were excised from movies and television shows. The material was coded by trained raters. Reliability indices were uniformly high for the seven categories (percentage agreement ranged from 0.90 to 0.98; kappas ranged from 0.66 to 0.94). RESULTS: Results indicated that fat stigmatization commentary and fat humor were often verbal, directed toward another person, and often presented directly in the presence of the overweight target. Results also indicated that male characters were three times more likely to engage in fat stigmatization commentary or fat humor than female characters. DISCUSSION: To our knowledge, these findings provide the first information regarding the specific gender, age, and types of fat stigmatization that occur frequently in movies and television shows. The stimuli should prove useful in future research examining the role of individual difference factors (e.g., BMI) in the reaction to viewing such vignettes.
