Objective: Binge eating disorder represents a significant public health problem, with up to 50% of weight loss program participants displaying this disorder. In previous studies with orlistat, patients with binge eating disorder were excluded. The goal of this study was to assess the efficacy of orlistat in obese patients with binge eating disorder. Research Methods and Procedures: Eighty‐nine patients with clinically diagnosed binge eating disorder and a BMI ≥ 30 kg/m2 were randomized in double‐blind fashion to 24 weeks of treatment with 120 mg of orlistat or placebo three times daily, in combination with a mildly reduced‐calorie diet. Results: After 24 weeks, the mean weight loss from baseline for orlistat‐treated patients was significantly greater than for patients receiving placebo (?7.4% vs. ?2.3%; p = 0.0001) (intent‐to‐treat analysis). The overall Eating Disorder Inventory 2 score at week 24 was significantly lower in patients treated with orlistat than in those in the placebo group (p = 0.011) Discussion: Orlistat may be considered as part of the management for patients with obesity and binge eating disorder. 相似文献

Objective: For binge eating disorder (BED) to be accepted as a distinct diagnostic category in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition, it must be demonstrated that the criteria identify a diagnostic entity that is distinct from bulimia nervosa and obesity. This study examined the difference in total energy intake per day, patterns of energy intake throughout the day, and nutrient content of foods consumed in obese individuals who met the criteria for BED (on binge and non‐binge days) and those who did not. Research Methods and Procedures: Twenty women, 12 who met Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for BED and 8 matched obese controls, participated in the study. All participants underwent six random 24‐hour dietary recall telephone interviews conducted by experienced interviewers using the Nutrition Data Software System. Results: The BED group ingested significantly more kilocalories on days when they had binge eating episodes than the obese control group on average. The BED group ate significantly more in the evening on binge days than their control group counterparts. There is some indication in the data that those with BED may be restricting caloric intake. Finally, data indicated that the BED group ate significantly more protein, carbohydrate, and fat on binge days than on non‐binge days. However, the proportion of kilocalories from each nutrient shifted on BED binge days compared with non‐binge days to favor consumption of fat over carbohydrates. Discussion: More research needs to be done to determine if these findings are reproducible. Then, the neurobiological underpinnings of these differences in nutrient intake patterns and nutrient selection can be studied to help to determine the biological basis of the disorder. 相似文献

Objective: To compare different methods for assessing the features of eating disorders in patients with binge eating disorder (BED). Research Methods and Procedures: A total of 47 participants with BED were administered the Eating Disorder Examination (EDE) Interview and completed the EDE‐Questionnaire (EDE‐Q) at baseline. A total of 37 participants prospectively self‐monitored their eating behaviors daily for 4 weeks and then completed another EDE‐Q. Results: At baseline, the EDE and the EDE‐Q were significantly correlated on frequencies of objective bulimic episodes (binge eating), overeating episodes, and on the dietary restraint, eating concern, weight concern, and shape concern subscales. Mean differences in the EDE and EDE‐Q frequencies of objective bulimic episodes and overeating were not significant but scores on the four subscales differed significantly, with the EDE‐Q yielding higher scores. At the 4‐week point, the EDE‐Q retrospective 28‐day assessment was significantly correlated with the prospective daily self‐monitoring records for frequency of objective bulimic episodes and the mean difference between the methods was not significant. The EDE‐Q and self‐monitoring findings for subjective bulimic episodes and objective overeating differed significantly. Discussion: In patients with BED, the three assessment methods showed some areas of acceptable convergence. 相似文献

Objective: To investigate the relationship between obesity/overweight and binge eating episodes (BEEs) in a large nonclinical population. Research Methods and Procedures: Consumers at shopping centers in five Brazilian cities (N = 2858) who participated in an overweight prevention program were interviewed and had weight and height measured to calculate BMI. Results: Prevalence of overweight (BMI = 25 to 29.9 kg/m2) was 46.6% for men and 36.6% for women. Obesity (BMI ≥ 30 kg/m2) was about two‐thirds of the prevalence of overweight. BEEs (subjects who binged one or more times per week over the last 3 months) in normal‐weight individuals was 1.4% for men and 3.9% for women, whereas in overweight/obese, these prevalences were 6.5% and 5.5%, respectively (p < 0.01). After adjustment for age, socioeconomic variables, and childhood obesity, those who reported BEEs had an odds ratio of being overweight/obese of 3.31 (95% confidence interval: 1.11 to 9.85) for men and 1.73 (95% confidence interval: 1.05 to 2.84) for women. Discussion: These findings indicate a strong association between episodes of binge eating and overweight/obesity, mainly among men. 相似文献

Objective: Although binge eating disorder is a common and distressing concomitant of obesity, it has not yet been established whether affected individuals presenting to behavioral weight control programs should receive specialized treatments to supplement standard treatment. This study was designed to examine the added benefit of two adjunctive interventions, individual cognitive behavioral therapy (CBT) and fluoxetine, offered in the context of group behavioral weight control treatment. Research Methods and Procedures: One hundred sixteen overweight/obese women and men with binge eating disorder were all assigned to receive a 16‐session group behavioral weight control treatment over 20 weeks. Simultaneously, subjects were randomly assigned to receive CBT + fluoxetine, CBT + placebo, fluoxetine, or placebo in a two‐by‐two factorial design. Outcome measures, assessed at the end of the 16‐session acute treatment phase, included binge frequency, weight, and measures of eating‐related and general psychopathology. Results: Overall, subjects showed substantial improvement in binge eating and both general and eating‐related psychopathology, but little weight loss. Subjects who received individual CBT improved more in binge frequency than did those not receiving CBT (p < 0.001), and binge abstinence was significantly more common in subjects receiving CBT vs. those who did not (62% vs. 33%, p < 0.001). Fluoxetine treatment was associated with greater reduction in depressive symptoms (p < 0.05). The 54 subjects who achieved binge abstinence improved more on all measures than the 62 subjects who did not. In particular, these subjects lost, on average, 6.2 kg compared with a gain of 0.7 kg among non‐abstainers. Discussion: Adjunctive individual CBT results in significant additional binge reduction in obese binge eaters receiving standard behavioral weight control treatment. 相似文献

Objective: To examine binge eating and eating‐related cognitions and behavior in a sample of ethnically diverse women who are severely obese and seeking bariatric surgery. Research Methods and Procedures: Female bariatric surgery candidates (62 African Americans, 18 Latinas, 130 whites) completed questionnaires on binge eating and eating‐related cognitions and behavior and completed a structured clinical interview to confirm binge‐eating disorder diagnosis. Results: Ethnic minorities and whites did not differ in rates of binge‐eating disorder (26.3%), binges per week (M = 0.95), or dietary restraint. Ethnic minorities reported less disinhibition, and there was a trend to report less hunger awareness than whites. After controlling for BMI and education, ethnicity accounted for significant variance in disinhibition (4%; p < 0.01). Ethnic minorities were younger, became overweight at a later age, and were overweight for fewer years than whites. Discussion: Results suggest that ethnicity exerts an important influence on disinhibition and that ethnic differences are not caused by BMI or education. Findings point to the need to continue to investigate the role of ethnicity, binge eating, and disinhibition in severely obese women, so that culturally appropriate services can be provided. 相似文献

Objective: Binge eating disorder (BED) is positively associated with obesity and psychological distress, yet the behavioral features of BED that drive these associations are largely unexplored. The primary aim of this study was to investigate which core behavioral features of binge eating are most strongly related to psychological disturbance. Methods and Procedures: A cross‐sectional study involved 180 bariatric surgery candidates, 93 members of a non‐surgical weight loss support group, and 158 general community respondents (81 men/350 women, mean age 45.8 ± 13.3, mean BMI 34.8 ± 10.8, BMI range 17.7–66.7). Validated questionnaires assessed BED and binge eating, symptoms of depression, appearance dissatisfaction (AD), quality of life (QoL) and eating‐related behaviors. Features of binge eating were confirmed by interview. BMI was determined by clinical assessment and self‐report. Results: The loss of control (LOC) over eating, that is, being unable to stop eating or control what or how much was consumed was most closely related to psychological markers of distress common in BED. In particular, those who experienced severe emotional disturbance due to feelings of LOC reported higher symptoms of depression (P < 0.001), AD (P = 0.009), and poorer mental health–related QoL (P = 0.027). Discussion: Persons who report subjective binge episodes or do not meet BED frequency criteria for objective binge episodes may still be at elevated risk of psychological disturbance and benefit from clinical intervention. Feelings of LOC could drive binge eaters to seek bariatric surgery in an attempt to gain control over body weight and psychologically disturbing eating behavior. 相似文献

Objective: This study assessed whether adding orlistat to sibutramine would induce further weight loss in patients who previously had lost weight while taking sibutramine alone. Research Methods and Procedures: Patients were 34 women with a mean age of 44.1 ± 10.4 years, weight of 89.4 ± 13.8 kg, and body mass index (BMI) of 33.9 ± 4.9 kg/m2 who had lost an average of 11.6 ± 9.2% of initial weight during the prior 1 year of treatment by sibutramine combined with lifestyle modification. Patients were randomly assigned, in double‐blind fashion, to sibutramine plus orlistat or sibutramine plus placebo. In addition to medication, participants were provided five brief lifestyle modification visits during the 16‐week continuation trial. Results: Mean body weight did not change significantly in either treatment condition during the 16 weeks. The addition of orlistat to sibutramine did not induce further weight loss as compared with treatment by sibutramine alone (mean changes = +0.1 ± 4.1 kg vs. +0.5 ± 2.1 kg, respectively). Discussion: These results must be interpreted with caution because of the study's small sample size. The findings, however, suggest that the combination of sibutramine and orlistat is unlikely to have additive effects that will yield mean losses ≥15% of initial weight, as desired by many obese individuals. 相似文献

Objective: To examine the effect of orlistat on dietary restraint, disinhibition, hunger, and binge eating and to understand the relation between changes in eating behavior and weight maintenance. Methods and Procedures: Subjects were 306 women and men (age: 19–45 years; BMI: 37.5 ± 4.1 kg/m2) included in the Scandinavian Multicenter study of Obese subjects with the Metabolic Syndrome, a 3‐year clinical trial of orlistat or placebo following an 8‐week very low energy diet (VLED). Outcomes were changes in weight and in the Three Factor Eating Questionnaire (TFEQ) and Binge Eating Scale (BES) between screening and 17 and 33 months after randomization. As reported previously, weight gain following VLED was lower in subjects treated with orlistat than with placebo. Results: Compared to screening results, dietary restraint was increased and disinhibition, hunger, and binge eating were decreased in both groups. These changes were similar in both groups with the exception of the hunger score at month 33 that was reduced more in the placebo than in the orlistat group (difference between groups ?1.1 (95% CI (?2.0, ?0.2)) P = 0.014). In multivariate analyses, scores for restraint, disinhibition and binge eating were associated with weight loss after adjustment for BMI, gender, age, and treatment (all P ≤ 0.002, model R 2 = 0.12–0.17). Discussion: Orlistat did not affect eating behavior differently in any substantial way than the placebo did in this long‐term weight maintenance trial. The results indicate that increased restraint and decreased disinhibition and binge eating are important for sustained weight maintenance in obese subjects with the metabolic syndrome. 相似文献

Objective: Prior research has shown that fasting alternated with a diet of standard rodent chow and a 10% sucrose solution produces bingeing on the sucrose, but animals remain at normal body weight. The present study investigated whether restricted access to a highly palatable combination of sugar and fat, without food deprivation, would instigate binge eating and also increase body weight. Methods and Procedures: Male rats were maintained for 25 days on one of four diets: (i) sweet‐fat chow for 2 h/day followed by ad libitum standard chow, (ii) 2‐h sweet‐fat chow only 3 days/week and access to standard chow the rest of the time, (iii) ad libitum sweet‐fat chow, or (iv) ad libitum standard chow. Results: Both groups with 2‐h access to the sweet‐fat chow exhibited bingeing behavior, as defined by excessively large meals. The body weight of these animals increased due to large meals and then decreased between binges as a result of self‐restricted intake of standard chow following binges. However, despite these fluctuations in body weight, the group with 2‐h access to sweet‐fat chow every day gained significantly more weight than the control group with standard chow available ad libitum. Discussion: These findings may have implications for the body weight fluctuations associated with binge‐eating disorder, as well as the relationship between binge eating and the obesity epidemic. 相似文献

Objective:
Despite the high prevalence of overweight and obesity in the US military veterans, binge eating has not been examined in this population.Design and Methods:
Using a secondary data analysis approach, the prevalence and correlates of self‐reported binge eating among 45,477 overweight or obese veterans receiving care in Veterans Health Administration facilities were examined. Participants completed a 23‐item survey that assessed demographics, weight history, physical and mental health comorbidities, and eating habits during routine medical clinic visits. χ2 and logistic regression were used to examine the relationships among binge eating and demographic variables and medical and psychiatric comorbidities.Results:
Nearly, three‐quarters of the sample reported clinically meaningful binge eating (i.e., two or more times per week). Binge‐eaters were more likely to report higher body mass index, depression, anxiety, and type 2 diabetes (P <0.0001). After controlling for potentially confounding variables, male veterans were significantly more likely to report clinically meaningful binge eating than female veterans (P < 0.001).Conclusion:
These results have important implications for modifying weight management programs and highlight the need for the assessment and treatment to address binge eating, particularly among men and patients with type 2 diabetes. 相似文献12.

Objective: Our objective was to assess the efficacy and safety of sibutramine with a low‐calorie diet (LCD) and commercial meal‐replacement product in achieving weight loss and weight‐loss maintenance in obese patients. Research Methods and Procedures: Eight U.S. centers recruited 148 obese patients for a 3‐month comprehensive weight‐loss therapy (Phase I) comprising daily sibutramine 10 mg + LCD (two Slim‐Fast meal‐replacement shakes, one low‐calorie meal; total kcal/d = 1200–1500). Patients (N = 113) who lost ≥5% of initial body weight during Phase I were randomized for a 9‐month period (Phase II) to daily sibutramine 15 mg + LCD (one meal‐replacement shake; two low‐calorie meals: total kcal/d ~1200–1500) or daily placebo + three low‐calorie meals (total kcal/d ~1200–1500). Both phases included behavior modification. Efficacy was assessed by body weight change during each phase and by the number of patients at endpoint maintaining ≥80% of the weight they had lost by the end of Phase I. Other outcomes included changes in cardiovascular and metabolic risk factors, adverse events, and vital signs. Results: Mean body weight change during Phase I was ?8.3 kg (p < 0.001). Patients randomized to sibutramine in Phase II had an additional ?2.5 kg mean weight loss vs. a 2.8‐kg increase in the placebo group (p < 0.001). More sibutramine patients maintained ≥80% of their Phase I weight loss at the end of Phase II (85.5% vs. placebo 36.7%, p < 0.001). Most adverse events were mild or moderate in severity, and all serious adverse events were unrelated to sibutramine. Discussion: Sibutramine plus LCD with meal replacements and behavior modification is a safe and effective strategy for achieving and sustaining weight loss in obese patients. 相似文献

Objective: To examine the occurrence of binge eating and its impact on weight loss outcomes among obese participants in the Trevose Behavior Modification Program, a lay‐administered, lay‐directed self‐help weight loss program offering continuing care. Research Methods and Procedures: Participants completed questionnaires, and weight loss data were recorded prospectively. Results: Although objective bulimic episodes were reported by 41% of the sample, objective bulimic episodes were not associated with worse weight loss outcomes. Mean weight loss after 12 months was 18.2 kg (18.8% of initial body weight) for the treatment completers and 10.3 kg (10.5% of initial body weight) for the full sample (using intent‐to‐treat analyses, with baseline scores carried forward). Discussion: Substantial long‐term weight loss, resulting from a continuing care treatment program, occurred in individuals both with and without frequent binge eating. 相似文献

Objective: To evaluate the safety and efficacy of sibutramine 15 mg by mouth once per day in obese patients over a period of 6 months. Research Methods and Procedures: A monocenter, double‐blind, placebo controlled, parallel, prospective clinical trial was carried out. Sixty‐nine male and female obese patients (body mass index [BMI] > 30 kg/m2) aged 16 to 65 years entered the trial. Results: 22 of 35 patients in the sibutramine group and 9 of 34 patients in the placebo group completed the trial. The high dropout rate in the sibutramine group was due to adverse events in 3 cases, lack of efficacy (as judged by patients) in 7, loss to follow‐up in 2, and an orthopedic device being worn in 1; in the placebo group the dropouts were ascribed to lack of efficacy (as judged by patients) in 17 cases and to loss to follow‐up in 8 cases. Using the method of last observation carried forward, the weight loss in the sibutramine group was 10.27 kg (95% confidence intervals [95% CI] 7.66; 13.07) and 1.26 kg (95% CI 0.3; 2.23) in the placebo group. The BMI loss was 4.17 kg/m2 (95% CI 3.11; 5.22) in the sibutramine group and 0.53 kg/m2 (95% CI 0.13; 0.92) in the placebo group. The waist circumference reduction was 12.51 cm (95% CI 9.25; 15.77) in the sibutramine group and 3.26 cm (95% CI 1.38; 5.14) in the control group (p < 0.05 by paired Student's t test for all the intragroup comparisons). Twenty‐three sibutramine patients had 34 adverse events, the most frequent adverse events in the sibutramine group were upper respiratory tract infections (n = 6) and constipation (n = 6); 16 placebo patients had 21 adverse events. Three sibutramine patients withdrew their informed consent when they had adverse events. Discussion: The results show that sibutramine induces significant loss of body weight and waist circumference. Cardiovascular function was not significantly affected by sibutramine. Sibutramine was well tolerated by most of the patients. 相似文献

Objective: African American women have a high prevalence of obesity, which partially may be explained by their lower rates of resting energy expenditure (REE). The aim of this study was to examine the influence of acute sibutramine administration on REE and post‐exercise energy expenditure in African American women. Research Methods and Procedures: A total of 15 premenopausal, African American women (age, 29 ± 5 years; body fat, 38 ± 7%) completed a randomized, double‐blind cross‐over design with a 30‐mg ingestion of sibutramine or a placebo. Each trial was completed a month apart in the follicular phase and included a 30‐minute measurement of REE 2.5 hours after sibutramine or placebo administration. This was followed by 40 minutes of cycling at ~70% of peak aerobic capacity and a subsequent 2‐hour measurement of post‐cycling energy expenditure. Results: There was no difference (p > 0.05) in REE (23.70 ± 2.81 vs. 23.69 ± 2.95 kcal/30 min), exercise oxygen consumption (1.22 ± 0.15 vs. 1.25 ± 0.15 liter/min), and post‐cycling energy expenditure (104.2 ± 12.7 vs. 104.9 ± 11.4 kcal/120 min) between the sibutramine and placebo trials, respectively. Cycling heart rate was significantly higher (p = 0.01) during the sibutramine (158 ± 14 beats/min) vs. placebo (150 ± 12 beats/min) trials. Discussion: These data demonstrate that acute sibutramine ingestion does not increase REE or post‐exercise energy expenditures but does increase exercising heart rate in overweight African American women. Sibutramine may, therefore, impact weight loss through energy intake and not energy expenditure mechanisms. 相似文献

Lack of control of food intake, excess size, and frequency of meals are critical to the development of obesity. The stomach signals satiation postprandially and may play an important role in control of calorie intake. Sodium alginate (based on brown seaweed Laminaria digitata) is currently marketed as a weight loss supplement, but its effects on gastric motor functions and satiation are unknown. We evaluated effects of 10 days treatment with alginate or placebo on gastric functions, satiation, appetite, and gut hormones associated with satiety in overweight or obese adults. We conducted a randomized, 1:1, placebo‐controlled, allocation‐concealed study in 48 overweight or obese participants with excluded psychiatric comorbidity and binge eating disorder. All underwent measurements of gastric emptying (GE), fasting, and postprandial gastric volumes (GVs), postprandial satiation, calorie intake at a free choice meal and selected gut hormones after 1 week of alginate (three capsules vs. matching placebo per day, ingested 30 min before the main meal). Six capsules were ingested with water 30 min before the GE, GV, and satiation tests on days 8–10. There were no treatment group effects on GE or volumes, gut hormones (ghrelin, cholecystokinin (CCK), glucagon‐like peptide‐1 (GLP‐1), peptide YY (PYY)), satiation, total and macronutrient calorie intake at a free choice meal. There was no difference detected in results between obese and overweight patients. Alginate treatment for a period of 10 days showed no effect on gastric motor functions, satiation, appetite, or gut hormones. These results question the use of short‐term alginate treatment for weight loss. 相似文献

Objective: This study assessed the long‐term effects of group behavioral treatment plus individual cognitive behavioral therapy (CBT) and/or fluoxetine in binge eating disorder (BED) patients. Research Methods and Procedures: A total of 116 individuals were randomized to an initial five‐month trial and were followed up over two years. Assessments, including binge frequency, weight, and self‐report measures, were administered at pre‐treatment, post‐treatment, and ~6, 12, 18, and 24 months after initial treatment. Results: Across treatment groups, there was overall improvement over 29 months in binge frequency and in binge abstinence. The odds of binge abstinence 2 years post‐treatment were 1.373 times the odds of binge abstinence immediately post‐treatment. There was no significant change in weight over the two‐year period. Subjects who received individual CBT evidenced lower binge frequency over the two‐year follow‐up period than patients who had not received individual CBT. Similarly, CBT was associated with increased rates of binge abstinence. There were no main effects of treatment assignment on weight over the two‐year follow‐up period. There was a significant advantage for fluoxetine assignment over the two‐year follow‐up period on depressive symptoms. Discussion: The major significance of the study rests in its examination of the long‐term effects of standardized interventions for BED. Our findings provide support for the ideas that short‐term treatment may confer long‐term benefit and that not all treatments are equivalent in the benefits they confer. 相似文献

Objective: To describe the prevalence of night eating in a community cohort of black and white girls, using different definitions of night eating as described in the literature. Research Methods and Procedures: Three‐day food diaries collected as part of the National Growth and Health Study were examined to identify episodes of night eating, which was defined in five different ways: eating >25% of daily caloric intake after the last evening meal, eating >25% of daily caloric intake after 7 pm, eating >50% of daily caloric intake after the last evening meal, eating >50% of daily caloric intake after 7 pm, or eating between 11 pm and 4:59 am. Results: Frequency of night eating varied tremendously depending on how the behavior was defined. For the least restrictive definition (>25% of total intake after last meal), 50% to 70% of girls reported one night eating event; for the most restrictive (>50% of total intake after last meal), only 1.5% of 11‐year‐old girls' diaries and 3.5% of 19‐year‐old girls' diaries contained a night eating event. The frequency of night eating decreased dramatically (typically by a factor of 10) if the inclusion criteria required multiple night eating events in a given week. Discussion: A standard definition of night eating behavior is needed to advance the field. An agreed‐on operationalized definition that includes time of day, amount of calories consumed, and a frequency criterion would enable cross‐study comparisons and encourage the examination of developmental and clinical considerations of night eating behavior. 相似文献

Objective: To examine the relationship among attempts to lose weight, restraint, and eating behavior in outpatients with binge eating disorder (BED). Research Methods and Procedures: Participants were 93 consecutive outpatients evaluated for a clinical trial who met Diagnostic and Statistical Manual, Fourth edition criteria for BED. The Eating Disorder Examination Interview was administered to assess attempts at weight loss, restraint, different forms of overeating, and the attitudinal psychopathology of eating disorders (i.e., concerns regarding eating, shape, and weight). In addition, the Three‐Factor Eating Questionnaire was used to assess cognitive restraint, hunger, and disinhibition. Psychometrically established measures were given to assess body dissatisfaction, depression, and self‐esteem. Results: The majority of participants (75.3%; N = 70) reported attempting to lose weight, but only 37.6% (N = 35) reported dietary restraint on at least half the days of the month. Dietary restraint and cognitive restraint were not associated with any form of binge eating or overeating. Dietary restraint and cognitive restraint were positively correlated with weight concern, shape concern, and body dissatisfaction, and negatively correlated with body mass index. To further examine the interplay between attempting to lose weight and restraint, three study groups were created: unrestrained nonattempters (21.5%, N = 20), unrestrained attempters (40.9%; N = 38), and restrained attempters (34.4%; N = 32). The three groups did not differ significantly on binge eating or other eating behaviors; however, significant differences were observed for weight concern, shape concern, and body dissatisfaction. Discussion: Attempts to lose weight and restraint are not synonymous for patients with BED. Although 75.3% of BED patients reported that they were attempting to lose weight, only 37.6% reported dietary restraint on at least half the days of the previous month. While restraint was negatively associated with body mass index, it was not related to binge eating or overeating. Our findings raise questions about prevailing models that posit restraint as a predominant factor in the maintenance of binge eating in BED. 相似文献

Bariatric surgery is the most effective treatment for severe obesity. However, evidence suggests that maladaptive eating behaviors such as binge eating, grazing, and a loss of control when eating may impact postsurgical weight outcomes. The current study sought to characterize the weight outcomes, eating patterns, and perceived health‐related quality of life of individuals 3–10 years following gastric bypass (GBP) surgery and to assess the relationships between eating behaviors, weight outcomes, and quality of life. Eligible participants (N = 497) completed an Internet survey of their eating behaviors, health‐related quality of life, and weight history. Participants self‐reported a mean maximum postsurgical loss of 81% of their excess weight and maintained a mean weight loss of 70% 3–10 years following surgery (mean 4.2 years). Eighty‐seven percent reported weight regain ranging from 1 to 124 lb (mean 22.6 lb). Frequency of binge eating, a loss of control when eating, and grazing were all significantly correlated with greater weight regain (binge eating r = 0.24, P = 0.006; loss of control r = 0.36, P < 0.01; grazing r = 0.39, P < 0.001) and lesser excess weight loss (EWL) (binge eating r = ?0.21, P = 0.013; loss of control r = ?0.41, P < 0.001; grazing r = ?0.27, P < 0.001). Poorer health‐related quality of life was associated with binge eating disorder (BED) (t[463] = 9.7, P < 0.001) and grazing two or more times per week (t[361] = 9.0, P < 0.001). These findings suggest that eating disturbances and a loss of control when eating are significant following GBP and are risk factors for diminished weight outcomes. 相似文献
