RESUMO

OBJECTIVE: Binge-eating disorder (BED) is a prevalent psychiatric disorder associated with obesity. Few evidence-based treatments exist for BED, particularly pharmacological options. This study tested the efficacy of naltrexone/bupropion for BED. METHODS: A randomized, double-blind, placebo-controlled, 12-week trial tested naltrexone/bupropion for BED with and without obesity. Eighty-nine patients (70.8% women, 69.7% White, mean age 45.7 y, mean BMI 35.1 kg/m2 , 77.5% with BMI ≥ 30 kg/m2 ) were randomized to placebo (n = 46) or naltrexone/bupropion (n = 43), with randomization stratified by obesity status and gender; 92.1% completed post-treatment assessments. RESULTS: Mixed models of binge-eating frequency revealed significant reductions that did not differ significantly between naltrexone/bupropion and placebo. Logistic regression of binge-eating remission rates revealed that naltrexone/bupropion and placebo did not differ significantly. Obesity status did not predict, or moderate, binge-eating outcomes considered either continuously or categorically. Mixed models revealed that naltrexone/bupropion was associated with significantly greater percentage weight loss than placebo. Logistic regression revealed that naltrexone/bupropion had significantly higher rates of attaining ≥5% weight loss than placebo (27.9% vs. 6.5%). Obesity status did not predict or moderate weight-loss outcomes. CONCLUSIONS: Naltrexone/bupropion did not demonstrate effectiveness for reducing binge eating relative to placebo but showed effectiveness for weight reduction in patients with BED. Obesity status did not predict or moderate medication outcomes.

RESUMO

BACKGROUND: Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but there is a dearth of controlled research examining pharmacotherapies as maintenance treatments for responders to initial interventions. This gap in the literature is particularly critical for pharmacotherapy for BED which is associated with relapse following discontinuation. The current study tested the efficacy of naltrexone/bupropion maintenance treatment amongst responders to acute treatments for BED. METHODS: Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested naltrexone/bupropion as maintenance treatment for responders to acute treatments with naltrexone/bupropion and/or behavioral weight-loss therapy for BED with comorbid obesity. Sixty-six patients (84.8% women, mean age 46.9, mean BMI 34.9 kg/m2) who responded to acute treatments were re-randomized to placebo (N = 34) or naltrexone/bupropion (N = 32) for 16 weeks; 86.3% completed posttreatment assessments. Mixed models and generalized estimating equations comparing maintenance treatments (naltrexone/bupropion v. placebo) included main and interactive effects of acute treatments. RESULTS: Intention-to-treat binge-eating remission rates following maintenance treatments were 50.0% (N = 17/34) for placebo and 68.8% (N = 22/32) for naltrexone/bupropion. Placebo following response to acute treatment with naltrexone/bupropion was associated with significantly decreased probability of binge-eating remission, increased binge-eating frequency, and no weight loss. Naltrexone/bupropion following response to acute treatment with naltrexone/bupropion was associated with good maintenance of binge-eating remission, low binge-eating frequency, and significant additional weight loss. CONCLUSIONS: Adult patients with BED with co-occurring obesity who have good responses to acute treatment with naltrexone/bupropion should be offered maintenance treatment with naltrexone/bupropion.

RESUMO

OBJECTIVE: Binge-eating disorder involves overeating while feeling a loss of control (LOC). Emotions around LOC appear to vary; some patients fear LOC whereas others feel powerless or "resigned" to LOC. This study examined differences in psychopathology among treatment-seeking patients with binge-eating disorder categorized with fear of LOC, resignation to LOC, and no fear/resignation of LOC. METHOD: Doctoral research clinicians administered diagnostic and semistructured interviews to characterize psychopathology and establish a diagnosis of binge-eating disorder in participants (N = 382). The interview assessed fear of LOC in the past month. Further queries assessed whether, in the absence of fear of LOC, patients were resigned to LOC or had no fear/resignation. RESULTS: Patients with fear of LOC and resigned to LOC endorsed significantly greater global eating-disorder psychopathology than patients with no fear/resignation. Patients with fear of LOC reported greater distress about binge eating and greater depression than those with no fear/resignation. Patients resigned to LOC reported significantly more frequent binge-eating episodes than those with fear of LOC and no fear/resignation. Black individuals and men were more likely to report no fear/resignation than other demographic groups. DISCUSSION: This study describes a novel clinical aspect of binge-eating disorder: resignation to LOC. Findings highlight the importance of including anticipatory cognitive-affective experiences in treatment formulations and planning. Future research should examine co-occurrence of these experiences and their association with impairment. Future research should also examine how fear of LOC and resignation to LOC change during treatment and whether they predict or moderate treatment outcomes. PUBLIC SIGNIFICANCE: Adults with binge-eating disorder have anticipatory cognitive-affective experiences about loss of control (LOC) over eating (i.e., fear of LOC, resigned to LOC, no fear nor resignation of LOC). Individuals who experience fear of LOC and those who are resigned to LOC had more severe psychopathology than those without fear/resignation. Binge-eating disorder has the highest prevalence of the eating disorders; thus, findings have high public significance in guiding clinicians' treatment planning.

RESUMO

OBJECTIVE: Binge-eating disorder, the most prevalent eating disorder, is a serious public health problem associated with obesity, psychiatric and medical comorbidities, and functional impairments. Binge-eating disorder remains underrecognized and infrequently treated, and few evidence-based treatments exist. The authors tested the effectiveness of naltrexone-bupropion and behavioral weight loss therapy (BWL), alone and combined, for binge-eating disorder comorbid with obesity. METHODS: In a randomized double-blind placebo-controlled trial conducted from February 2017 to February 2021, using a 2×2 balanced factorial design, 136 patients with binge-eating disorder (81.6% women; mean age, 46.5 years; mean BMI, 37.1) were randomized to one of four 16-week treatments: placebo (N=34), naltrexone-bupropion (N=32), BWL+placebo (N=35), or BWL+naltrexone-bupropion (N=35). Overall, 81.7% of participants completed independent posttreatment assessments. RESULTS: Intention-to-treat binge-eating remission rates were 17.7% in the placebo group, 31.3% in the naltrexone-bupropion group, 37.1% in the BWL+placebo group, and 57.1% in the BWL+naltrexone-bupropion group. Logistic regression of binge-eating remission revealed that BWL was significantly superior to no BWL, and that naltrexone-bupropion was significantly superior to placebo, but there was no significant interaction between BWL and medication. Mixed models of complementary measures of binge-eating frequency also indicated that BWL was significantly superior to no BWL. The rates of participants attaining 5% weight loss were 11.8% in the placebo group, 18.8% in the naltrexone-bupropion group, 31.4% in the BWL+placebo group, and 38.2% in the BWL+naltrexone-bupropion group. Logistic regression of 5% weight loss and mixed models of percent weight loss both revealed that BWL was significantly superior to no BWL. Mixed models revealed significantly greater improvements for BWL than no BWL on secondary measures (eating disorder psychopathology, depression, eating behaviors, and cholesterol and HbA1c levels). CONCLUSIONS: BWL and naltrexone-bupropion were associated with significant improvements in binge-eating disorder, with a consistent pattern of BWL being superior to no BWL.

RESUMO

PURPOSE: Post-operative loss-of-control (LOC)-eating is a negative prognostic indicator for long-term outcomes following bariatric surgery. Emerging research suggests that night eating might also be associated with poorer post-operative outcomes. This study examined the co-occurrence and clinical features of night eating in patients with LOC-eating following bariatric surgery. METHODS: Participants were 131 adults who sought treatment for eating/weight concerns 6 months following sleeve gastrectomy. The Eating Disorder Examination (EDE) interview (Bariatric-Surgery-Version) assessed LOC-eating, regular night eating (at least weekly), and eating-disorder psychopathology. Participants completed the Night Eating Questionnaire (NEQ), Beck Depression Inventory (BDI-II), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: Approximately, 15% met screening criteria for night-eating syndrome based on the NEQ. Greater NEQ scores were associated significantly with race, lower percent total weight loss (%TWL), and greater EDE, BDI-II, and PSQI scores. Similar results were observed when comparing groups with regular night eating (21.4%) versus without (78.6%); adjusting for race and %TWL revealed similar findings. DISCUSSION: In post-bariatric patients with LOC-eating, 15% likely had night-eating syndrome and 21.4% engaged in regular night-eating behavior. The co-occurrence of LOC-eating and regular night eating following sleeve gastrectomy may represent a more severe subgroup with elevated psychopathology, poorer sleep and %TWL. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort or case-control analytic studies.

RESUMO

OBJECTIVE: This secondary analysis examined physical activity (PA) changes and their prognostic significance among Latinx patients with obesity, with and without binge eating disorder (BED), who participated in a randomized, placebo-controlled trial testing the addition of orlistat to behavioral weight-loss (BWL) treatment in a "real-world" clinical setting. METHODS: In this randomized controlled trial at a community mental health center serving economically disadvantaged Spanish-speaking-only Latinx patients, 79 patients with obesity (40 with BED and 39 without BED) received BWL treatment and were randomized to orlistat or placebo. PA, weight, depression, and binge eating were assessed at baseline, posttreatment (end of treatment [4 months]), and the 6-month follow-up (10 months after baseline). RESULTS: PA was low at baseline (9.3% categorized as "active"), increased during treatment (32.9% categorized as "active" at posttreatment), and declined from posttreatment to the 6-month follow-up (28.2% classified as "active"). At baseline, PA was lower among patients with BED than those without BED. Changes in PA during and after treatment did not differ by BED status or medication condition. PA change was associated with reduced depression but not weight loss. CONCLUSIONS: Latinx patients with obesity receiving BWL treatment achieved significant, albeit modest, increases in PA. Although PA changes were not associated with weight loss, they were associated with reduced depression. Identifying methods to increase PA further is necessary.

RESUMO

OBJECTIVE: Internalized weight bias (IWB), or negative weight related self-evaluation, is associated with eating-disorder psychopathology and common among patients seeking bariatric surgery, but little is known about the clinical presentation of IWB post-operatively. This study examined IWB and clinical correlates among adult patients with loss-of-control (LOC) eating post-sleeve gastrectomy surgery. METHODS: Participants (N = 145) were sleeve gastrectomy patients seeking treatment for eating/weight concerns and experiencing regular LOC eating approximately 6 months following surgery. Eating-disorder features were assessed with the Eating Disorder Examination-Bariatric Surgery Version interview (EDE-BSV) and participants completed established measures assessing IWB, depression, and mental and physical components of quality of life. RESULTS: IWB was not associated significantly with percent excess weight loss, age, or gender, but White participants reported significantly greater IWB than Non-White participants. IWB was significantly associated with greater eating-disorder psychopathology, depression, and lower perceived mental quality of life. Hierarchical regression analysis revealed that IWB significantly predicted variance in eating-disorder psychopathology above and beyond other related variables. CONCLUSIONS: Findings suggest that IWB is common and associated with a range of heightened eating-disorder and psychosocial difficulties among patients experiencing LOC eating following bariatric surgery. Future research exploring the longitudinal post-operative prognostic significance of IWB is recommended.

RESUMO

PURPOSE: Binge-eating disorder (BED), the most prevalent eating disorder, is associated strongly with obesity and functional impairments. Few evidence-based treatments for BED exist; a pharmacotherapy effective in reducing both binge eating and weight needs to be identified. This placebo-controlled double-blind pilot RCT evaluated the acute effects of naltrexone + bupropion (NB) on BED with obesity and examined the longer-term effects through 6-month follow-up after the discontinuation of medication. METHODS: Twenty-two adult patients with BED were randomized to receive 12 weeks of double-blind treatment with fixed-dose NB (naltrexone + bupropion XL 50/300 mg) or placebo. Independent (blinded) researcher-clinicians evaluated patients at major outcome time points (baseline, posttreatment, and 6-month follow-up after the treatment period); patients were also evaluated for the tracking of course/tolerability throughout treatments and at 3-month follow-up. Primary outcomes were changes from baseline in binge-eating frequency and percentage weight. Secondary outcomes were changes in eating-disorder psychopathology and depression. FINDINGS: A total of 22 patients were enrolled (86.4% women; mean age, 50.4 years), with 77.3% of patients completing treatments; completion rates (NB, 83.3%; placebo, 70.0%) and adverse events did not differ significantly between NB and placebo. Analyses revealed significant reductions from baseline in binge-eating, eating-disorder psychopathology, depression, and weight during treatment, but these changes with NB did not differ significantly from those with placebo. The percentage of patients who attained 3% weight loss was significantly greater with NB than with placebo (45.5% vs 0%); weight-loss and binge-eating reductions were significantly correlated in the group that received NB. At 6-month follow-up, outcomes remained improved relative to baseline, with no significant differences between NB and placebo. IMPLICATIONS: The findings from this pilot RCT suggest that NB was well-tolerated in these patients with BED and comorbid obesity. Most outcomes were not statistically different between NB and placebo. A larger-scale, adequately powered RCT is needed for determining the efficacy of NB in the treatment of BED.

RESUMO

BACKGROUND: Clinical assessment of eating behaviors with patients who undergo bariatric surgery is challenging because of the complexity of symptom presentation postoperatively. The Eating Disorder Examination (EDE) is a widely-used semistructured clinical interview of eating-disorder psychopathology, yet no studies have examined the interrater reliability among postoperative bariatric surgery patients. OBJECTIVES: The present study aimed to examine the interrater reliability of the EDE, and an alternative classification of size-specific thresholds of binge-eating episodes in a postoperative bariatric surgery sample. SETTING: University School of Medicine, United States. METHODS: Participants interviewed were a randomly selected subset (n = 20) from a consecutive series of adults seeking treatment for eating concerns after bariatric surgery. Audio-taped interviews were rated independently by 1 of 4 expert raters. Interrater reliability was assessed using intraclass correlation coefficients (ICC) and kappa statistic. RESULTS: ICCs for the original 4 EDE subscales were excellent, ranging from .88 to .98. ICCs for the alternative brief 3 subscales were also excellent, with a range of .78 to .97. ICCs for bariatric loss-of-control eating episodes were in the good to excellent range, with a range of .66 to .99. Kappa agreement for bariatric overeating episodes was moderate (.60). CONCLUSIONS: These findings, based on 4 expert raters, suggest that complex eating-disorder psychopathology, as well as the newly proposed eating behavior with size thresholds relevant to bariatric patients, can be reliably assessed. To our knowledge, this is the first study to provide initial evaluation and support for the interrater reliability of the original EDE with additional modified eating categories developed for postbariatric surgery patients.

RESUMO

OBJECTIVE: Bariatric surgery affects the quantity of food individuals can eat, yet some individuals still experience loss of control (LOC) while eating. This cross-sectional study examined a new classification system for binge/LOC eating following bariatric surgery. METHODS: A total of 168 individuals who underwent bariatric surgery 6 months earlier and reported LOC eating were administered the Eating Disorder Examination-Bariatric Surgery Version interview and self-report measures of depressive symptoms, functional impairment, and physical and mental health-related quality of life. Three groups were created based on the largest LOC-eating episode determined by the Eating Disorder Examination-Bariatric Surgery Version interview as follows: (1) "traditional" objective binge-eating episodes, defined as eating unusually large quantities of food while having LOC; (2) "bariatric-objective binge eating," meaning unusually large quantities for postsurgical bariatric patients with LOC; and (3) "bariatric-subjective binge eating," meaning small quantities of food with LOC after surgery. RESULTS: In total, 75% (n = 126) met criteria for the bariatric-objective binge episodes group, 10% (n = 17) met criteria for the traditional objective binge-eating group, and 15% (n = 25) met criteria for the bariatric-subjective binge episodes group. The three groups differed significantly, with a graded pattern by binge size, in global eating-disorder psychopathology, depressive symptoms, and functional impairment but not quality of life. CONCLUSIONS: These findings provide empirical support for a new classification system for bariatric binge/LOC eating. Binge size was associated with distinct psychopathology. Longitudinal follow-up is needed to ascertain effects on clinical outcomes.

RESUMO

OBJECTIVE: Patients 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. METHODS: A 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. RESULTS: Of 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. CONCLUSIONS: Many 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.

RESUMO

OBJECTIVE: While physical activity (PA) is known to have positive effects on psychological and physical health, little is understood about the association between non-compensatory PA (ie, not compulsive or intended to control weight or shape) and psychopathology among individuals with eating-disorder features. The present study explored associations between non-compensatory PA and psychopathology among adults categorised with bulimia nervosa (BN) and binge-eating disorder (BED). We further explored the association between compensatory PA and psychopathology among those who engaged in that form of "purging." METHOD: Participants were recruited through Mechanical Turk, an online recruitment platform. Individuals categorised with core features of BED (N = 138) and BN (N = 138) completed measures of eating-disorder psychopathology (Eating Disorder Examination - Questionnaire [EDE-Q] and Questionnaire on Eating and Weight Patterns - 5), depression (Patient Health Questionnaire - 2) and PA (both non-compensatory and compensatory, measured using the EDE-Q and Godin Leisure-Time Exercise Questionnaire). RESULTS: Engagement in non-compensatory PA was associated with lower frequency of binge-eating episodes, lower overvaluation of shape/weight and lower dissatisfaction with shape/weight (Ps < .05). Engagement in compensatory PA was related to greater frequency of binge-eating episodes and greater restraint (Ps < .05). DISCUSSION: Non-compensatory PA was associated with lower eating-disorder psychopathology. This suggests that PA is an important, though understudied, health behaviour among persons with features of BED and BN. Future research should examine the potential role of non-compensatory PA in interventions for individuals with core features of these eating disorders.

RESUMO

OBJECTIVE: Some individuals eat furtively and conceal evidence of eating, and this seems to occur beyond binge-eating episodes. This type of secretive eating is common among youth and emerging evidences suggests that it is a relevant marker of eating disorder psychopathology among adults with significant eating and weight concerns. METHOD: We assessed secretive eating, loss-of-control (LOC) eating, and eating disorder psychopathology using investigator-based interviews among treatment-seeking adults experiencing LOC eating following bariatric surgery (N = 168). Participants also completed an established depression measure; height and weight were measured. RESULTS: Overall, 37% of patients reported secretive eating: 54% of patients who met criteria for binge-eating disorder except for the size criterion ("bariatric BED") and 25% of patients with subthreshold bariatric BED reported secretive eating. Many clinical variables were higher among patients with secretive eating compared to those without secretive eating; however, only eating disorder psychopathology severity and body dissatisfaction remained significantly higher among patients with secretive eating compared to those without when bariatric BED status was also included as a variable in the model. DISCUSSION: Findings suggest that among post-bariatric surgery patients with LOC eating, secretive eating signals more severe eating disorder psychopathology overall and specifically related to dissatisfaction with weight and shape. Bariatric BED status, however, has a stronger association than secretive eating with many clinical variables. Secretive eating should be assessed and considered when addressing weight and shape concerns among patients experiencing LOC eating after bariatric surgery.

RESUMO

OBJECTIVE: This study aimed to examine racial differences in postoperative eating-disorder psychopathology, psychosocial functioning, and weight loss among adults with loss-of-control (LOC) eating following sleeve gastrectomy. METHODS: Participants were 123 patients (n = 74 non-Hispanic White and n = 49 non-Hispanic Black) who underwent sleeve gastrectomy surgery within the previous 4 to 9 months and reported regular LOC eating during the previous month. The Eating Disorder Examination Bariatric Surgery Version assessed LOC eating, eating-disorder psychopathology, and meal patterns. Participants completed self-report measures, including the Beck Depression Inventory-II and Medical Outcomes Study Short-Form Health Survey. RESULTS: Presurgical BMI did not differ by race, but Black patients had significantly less percent total weight loss and percent excess weight loss than White patients. Black and White patients did not differ significantly in LOC eating frequency, onset time of postoperative LOC eating, eating-disorder psychopathology, depressive symptoms, or physical or mental health-related quality of life. White patients were significantly more likely to meet criteria for lifetime binge-eating disorder than Black patients. Black patients were significantly more likely to skip breakfast and dinner and engage in night eating than White patients. CONCLUSIONS: Our findings suggest that among patients with LOC eating following sleeve gastrectomy surgery, there exist few racial differences in current eating-disorder psychopathology and psychosocial functioning, although Black patients achieved less weight loss than White patients.

RESUMO

OBJECTIVE: To examine physical activity and correlates among three subgroups of adults: healthy weight without binge eating (HW), overweight/obesity without binge eating (OW/OB), and core features of binge-eating disorder (BED). METHOD: Participants (N = 2,384) completed an online survey with established measures of physical activity, eating psychopathology, and health. Most participants were White (82.6%) women (66.7%). Participants were categorized into three study groups: HW (n = 948; 39.9%), OW/OB (n = 1,308; 55.1%), and BED (n = 120; 5.1%). RESULTS: The BED group had the highest proportion of self-reported insufficiently active individuals (63.8%), followed by OW/OB (41.7%), and HW (29.2%). Associations between self-reported physical activity, eating pathology, and health were generally small in HW and OW/OB groups, whereas associations were moderate in the BED group. Self-reported weekly bouts of physical activity were more strongly, positively related to self-reported physical health for OW/OB than HW, and this effect was even more pronounced for BED compared with HW or OW/OB. DISCUSSION: This is the first study, to our knowledge, to demonstrate a stronger association between self-reported physical activity and physical health for individuals with BED compared with OW/OB alone. The high rate of physical inactivity and the strong association between physical activity and health among participants with BED suggest physical activity as an important treatment target for individuals with BED.

RESUMO

OBJECTIVE: This study aimed to address a cultural gap in the food addiction (FA) literature by examining FA and associated clinical features in a nonclinical group of men and women residing in India. METHOD: Participants (N = 415) were recruited from Amazon Mechanical Turk to complete an online survey about weight and eating. Participants completed self-report measures assessing FA (Yale Food Addiction Scale [YFAS]), eating-disorder psychopathology (Eating Disorder Examination-Questionnaire [EDE-Q]), health-related quality of life (Short Form Health Survey-12-item version [SF-12]), and depression (Patient Health Questionnaire-2). RESULTS: The FA symptom mean was 3.53 (SD = 1.90); 32.5% (n = 129) met FA clinical threshold on the YFAS. Groups categorized with and without FA on the YFAS did not differ significantly in sex or body mass index. YFAS scores were significantly correlated with greater frequency of binge eating, higher severity scores on all EDE-Q subscales, higher depression, and poorer functioning scores on the SF-12 (all ps < 0.05). CONCLUSIONS: FA, as conceptualized and measured by the YFAS, appears to be common among individuals residing in India.

RESUMO

BACKGROUND: Postoperative loss-of-control (LOC) eating is related to poorer weight loss outcomes after bariatric surgery, but little is known about LOC eating after sleeve gastrectomy surgery. OBJECTIVES: To examine LOC eating severity and weight loss after sleeve gastrectomy SETTING: University School of Medicine, United States METHODS: Participants were 71 individuals (84.5% female; n = 60) who underwent sleeve gastrectomy surgery within the previous 4 to 9 months and reported LOC eating at least once weekly during the previous 28 days. LOC eating was assessed using the Eating Disorder Examination (EDE) Bariatric Surgery Version. Current mean age and body mass index were 47.3 (SD = 10.1) years and 37.9 (SD = 8.2) kg/m2. Two groups, bariatric binge-eating disorder (Bar-BED) and loss-of-control eating only (LOC-only), were created based on modified binge-eating disorder (BED) criteria, which excluded the "unusually large quantity of food" criterion due to limited gastric capacity postsurgery. Bar-BED criteria mirrored BED criteria and consisted of the following: at least 12 LOC eating episodes over the prior 3 months (once weekly), 3 of 5 associated symptoms, marked distress over LOC eating, and lack of regular compensatory behaviors. RESULTS: Based on these revised criteria, 49.3% (n = 35) were classified as the Bar-BED group and 50.7% (n = 36) as the LOC-only group. Compared with the LOC-only group, the Bar-BED group had significantly greater EDE global and subscale scores and lower percent weight loss by 6 months postsurgery. CONCLUSION: Findings suggest LOC eating that parallels BED postsurgery is associated with poorer outcomes after sleeve gastrectomy including poorer weight loss and greater severity of eating-disorder psychopathology.

RESUMO

Ethnic minority populations in the United States are disproportionately affected by obesity. To address this disparity, research has begun to investigate the role of culture, ethnicity, and experiences with racism on food choices and health interventions. The aim of the current study was to develop and evaluate a new scale measuring the extent to which individuals' culture, as they perceive it, influences perceptions of food-related health messages. A diverse sample of 422 college students responded to the item pool, as well as surveys on race-related stress, self-efficacy in making healthy food choices, ethnic identity, and social support for health-related behaviors. Exploratory and confirmatory factor analyses produced a five-factor model: Connection (the extent to which food connected individuals with their culture), Authority (beliefs that health care providers were familiar with individuals' cultural foods), Unhealthy Food Perceptions (beliefs that individuals' cultural foods were perceived as unhealthy), Healthy Food Perceptions (beliefs that others perceive individuals' cultural foods to be healthy), and Social Value (the extent to which social relationships are improved by shared cultural food traditions). Authority and Healthy Food Perceptions were related to individuals' confidence in their ability to make healthy food choices. Authority was inversely correlated with negative coping with racism-related events. Ethnic identity was significantly correlated with all but Unhealthy Food Perceptions. Race/ethnicity differences were identified for Healthy Food Perceptions, Unhealthy Food Perceptions, Social Value, Connection, but not Authority. Applications and suggestions for further research using the Culturally-based Communication about Health, Eating, and Food (CHEF) Scale are proposed.

RESUMO

CONTEXT: Anorexia nervosa (AN) and functional hypothalamic amenorrhea (HA) are associated with low bone density, anxiety, and depression. Women with AN and HA have elevated cortisol levels. Significant hypercortisolemia, as in Cushing's disease, causes bone loss. It is unknown whether anxiety and depression and/or cortisol dysregulation contribute to low bone density in AN or HA. OBJECTIVE: Our objective was to investigate whether hypercortisolemia is associated with bone loss and mood disturbance in women with HA and AN. DESIGN AND SETTING: We conducted a cross-sectional study in a clinical research center. PARTICIPANTS: We studied 52 women [21 healthy controls (HC), 13 normal-weight women with functional HA, and 18 amenorrheic women with AN]. OUTCOME MEASURES: Serum samples were measured every 20 min for 12 h overnight and pooled for average cortisol levels. Bone mineral density (BMD) was assessed by dual-energy x-ray absorptiometry (DXA) at anteroposterior and lateral spine and hip. Hamilton Rating Scales for Anxiety (HAM-A) and Depression (HAM-D) were administered. RESULTS: BMD was lower in AN and HA than HC at all sites and lower in AN than HA at the spine. On the HAM-D and HAM-A, AN scored higher than HA, and HA scored higher than HC. Cortisol levels were highest in AN, intermediate in HA, and lowest in HC. HAM-A and HAM-D scores were associated with decreased BMD. Cortisol levels were positively associated with HAM-A and HAM-D scores and negatively associated with BMD. CONCLUSIONS: Hypercortisolemia is a potential mediator of bone loss and mood disturbance in these disorders.
