Loss of control over eating reflects eating disturbances and general psychopathology.

This study examined the clinical significance of the loss of control over eating as a key component of eating disorders. It investigated the association of eating-related psychopathology and general psychopathology with objective bulimic episodes (OBEs; experiencing a loss of control while consuming large amounts of food) and subjective bulimic episodes (SBEs; experiencing a loss of control while consuming small/moderate amounts). A community sample of 81 women with a range of disordered eating was recruited: binge-eating disorder, bulimia nervosa, subclinical eating disturbances, or no eating disorders. They were interviewed using the Eating Disorder Examination and completed measures of eating-related and general psychopathology. Both OBE and SBE frequencies correlated significantly with measures of eating-related and general psychopathology, and no significant differences were found between the magnitudes of the correlations with either binge episode type. SBE frequency significantly and independently predicted global eating disorder psychopathology. The loss of control over eating, without consuming large amounts of food, was as closely associated with specific eating disorder psychopathology and general mental health as were traditionally defined OBEs. SBEs may be an important target of treatment and should be considered for future diagnostic classifications of eating disorders.

Binge eating and weight loss in a self-help behavior modification program.

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.

The perceived effectiveness of continuing care and group support in the long-term self-help treatment of obesity.

OBJECTIVE: Obesity is increasingly considered a chronic disease requiring continuing care, but professional long-term treatment for most patients is not available. This study examined treatment recipients' perception of the effectiveness of different components of a group self-help, continuing-care treatment program for obesity. RESEARCH METHODS AND PROCEDURES: Members (n = 120) and volunteer leaders (n = 66) of a self-help, continuing-care treatment program of previously demonstrated effectiveness (mean treatment duration, 40.6 months; mean weight lost, 14.1 kg) rated how helpful and effective they found the various therapeutic strategies used by this program. The strategies examined were continuing care, group support, behavior therapy, motivational enhancement strategies involving positive reinforcement, and motivational enhancement strategies involving punishment. RESULTS: The single most highly valued aspect of treatment was the provision of continuing care, followed by group support. Greater success at achieving one's goal weight was associated with perceptions of greater effectiveness of the program's strategies overall (r = 0.219, p < 0.005), of continuing care (r = 0.225, p < 0.005), and of positive reinforcement strategies (r = 0.223, p < 0.01). Participants who had successfully attained their goal weight perceived behavior therapy strategies as more effective than did participants who had not reached their goal weight [t(170) = 2.93, p < 0.005]. DISCUSSION: The high ratings given to continuing care and group support strategies indicate the acceptability of supportive self-help treatment for obesity administered over the long term. The findings suggest that continuing care and group support should be made available to participants in the self-help treatment of obesity.

Stigmatized students: age, sex, and ethnicity effects in the stigmatization of obesity.

OBJECTIVE: To assess the stigmatization of obesity relative to the stigmatization of various disabilities among young men and women. Attitudes across ethnic groups were compared. In addition, these findings were compared with data showing severe stigmatization of obesity among children. RESEARCH METHODS AND PROCEDURES: Participants included 356 university students (56% women; mean age, 20.6 years; mean BMI, 23.3 kg/m2; range, 14.4 to 45.0 kg/m2) who ranked six drawings of same-sex peers in order of how well they liked each person. The drawings showed adults with obesity, various disabilities, or no disability. These rankings were compared with those obtained through a similar procedure with 458 fifth- and sixth-grade children. RESULTS: Obesity was highly stigmatized relative to physical disabilities. African-American women liked obese peers more than did African-American men, white men, or white women [F(1,216) = 4.02, p < 0.05]. Overweight and obese participants were no less stigmatizing of obesity than normal weight participants. Adults were more accepting than children of their obese peers [t(761) = 9.16, p < 0.001]. DISCUSSION: Although the stigmatization of obesity was high among participants overall, African-American women seemed to have more positive attitudes toward obesity than did white women, white men, or African-American men. Participants' weight did not affect their stigmatization of obesity: obese and overweight adults were as highly stigmatizing of obesity as non-overweight adults. Such internalized stigmatization could help to explain the low self-esteem and poor body image among obese young adults. However, adults seemed to have more positive attitudes about obesity than children. An understanding of the factors that limit the stigma of obesity among African-American women could help efforts to reduce stigma.

Binge eating and satiety in bulimia nervosa and binge eating disorder: effects of macronutrient intake.

OBJECTIVE: The current study tested the hypothesis that supplemental dietary protein would reduce binge eating frequency and test meal intake in women with bulimia nervosa (BN) or binge eating disorder (BED). METHOD: Eighteen women with BN or BED ingested high-carbohydrate or high-protein supplements (280 kcal) three times daily over two 2-week periods. On the morning after each period, participants were given a high-protein or high-carbohydrate supplement (420 kcal) 3 hr before an ad libitum meal. RESULTS: Binge eating episodes occurred less frequently during protein supplementation (1.12 episodes per week) than during carbohydrate supplementation (2.94 episodes per week) or baseline (3.01 episodes per week). Participants reported less hunger and greater fullness, and consumed less food at test meals, after protein than after carbohydrate (673 vs. 856 kcal). DISCUSSION: Adding protein to the diets of women with BN and BED reduced food intake and binge eating over a 2-week period. These findings may have implications for the longer-term treatment of these disorders.

Gastric bypass in a low-income, inner-city population: eating disturbances and weight loss.

OBJECTIVE: To examine the prevalence of eating disturbances and psychiatric disorders among extremely obese patients before and after gastric bypass surgery and to examine the relationship between these disturbances and weight outcomes. RESEARCH METHODS AND PROCEDURES: Sixty-five women patients (ages 19 to 67) with a mean BMI of 54.1 were assessed by semistructured psychiatric interview before surgery and by telephone interview after surgery (mean follow-up: 16.4 months) to determine psychiatric status, eating disturbances, and weight and health-related variables. RESULTS: Patients lost a mean of 71% of their excess BMI, with significantly poorer weight loss outcomes among African Americans. Psychiatric disorders remained prevalent before (37%) and after (41%) surgery. In contrast, binge eating disorder dropped from 48% to 0%. Psychiatric diagnosis did not affect weight outcomes. Instead, more frequent preoperative binge eating, along with greater initial BMI, follow-up length, and postoperative exercise, predicted greater BMI loss. Postsurgical health behaviors (exercise and smoking) and nocturnal eating episodes were also linked to weight loss. Exercise frequency increased and smoking frequency tended to decrease after surgery. DISCUSSION: These findings indicated that eating and psychiatric disturbances did not inhibit weight loss after gastric bypass and should not contraindicate surgery. Prior binge eating, eliminated after surgery, predicted BMI loss and, thus, may have previously been a maintaining factor in the obesity of these patients. The association between health behaviors and outcome suggests possible targets for intervention to improve surgical results. Poorer outcomes among African Americans indicate that these patients should be closely monitored and supported after surgery.

Getting worse: the stigmatization of obese children.

OBJECTIVE: The prevalence of childhood obesity more than doubled in the period from 1961 to 2001. We replicated a 1961 study of stigma in childhood obesity to see what effect this increased prevalence has had on this stigma. RESEARCH METHODS AND PROCEDURES: Participants included 458 5th- and 6th-grade children attending upper-middle and lower-middle income U.S. public schools. Children ranked six drawings of same-sex children with obesity, various disabilities, or no disability ("healthy"), in order of how well they liked each child. RESULTS: Children in both the present and the 1961 study liked the drawing of the obese child least. The obese child was liked significantly less in the present study than in 1961 [Kruskal-Wallis H(1) = 130.53, p < 0.001]. Girls liked the obese child less than boys did [H(1) = 5.23, p < 0.02]. Children ranked the healthy child highest and significantly higher than in 1961 [H(1) = 245.40, p < 0.001]. The difference in liking between the healthy and obese child was currently 40.8% greater than in 1961. DISCUSSION: Stigmatization of obesity by children appears to have increased over the last 40 years.
