“…In order to determine the extent of body size distortion within each group, the cut-points used previously 7 were employed to classify subjects as either underestimators ( 715%) or overestimators (!15%) or accurate estimators (!15% and`15%) of actual body size using their mean REAL body size estimates. A percentage table for estimation accuracy by WHR group is presented in Table 4.…”

“…6 Greater variability in the accuracy of body size estimation has been noted in the obese relative to normal-weight controls. In one study, 7 researchers found that 16% of obese subjects underestimated their size by more than 15%, 32% overestimated their size by more than 15%, and 52% made an accurate estimate. In contrast, 80% of normal-weight controls made an accurate estimate of their body size and only 10% either underestimated or overestimated their size by more than 15%.…”

Body fat distribution is a reliable predictor of the health risks of obesity. Abdominal obesity (AO) has been associated with various health complications whereas gluteal-femoral obesity (GFO) appears to be less hazardous. Body size overestimation, a type of body image disturbance, is found in a subset of obese persons. OBJECTIVE: The current study examined body size estimation accuracy as a function of body fat distribution. DESIGN: Cross-sectional, retrospective review of clinical records. SUBJECTS: 101 obese women (Mean age 39.4) joining a weight loss program. MEASUREMENTS: Subjects provided body size estimates using a live video distortion procedure and were grouped into tertiles (AO; Mixed type obesity (MTO); GFO) on the basis of their waist-to-hip ratios. RESULTS: GFO women had signi®cantly lower body size estimates and felt thinner than did AO or MTO women. In addition, more AO women (20.6% vs GFO: 8.8%) overestimated their body size by more than 15% whereas more GFO women (29.4% vs AO: 5.9%) underestimated their body size by more than 15%. CONCLUSION: Body fat distribution appears to be a mediator in body size estimation accuracy. These ®ndings are discussed in terms of possible differences in perceptual and societal experiences among the groups.

“…On image distortion, three studies found overestimation (Gleghorn, et al, 1987;Collins, et al, 1987;Lindholm & Wilson, 1988), one (Freeman, et al, 1985) found it to be present only in those without a history of anorexia nervosa, and one did not find any difference (Huon & Brown, 1986). On the analogue technique, three studies found overestimation (Norris, 1984;Willmuth, Leitenberg, Rosen, Fondacaro, & Gross, 1985;Gleghorn, et al, 1987), one did not (Birtchnell,Lacey,& Harte,3985), whereas one found it only in those without a history of being underweight , a finding contrary to that reported by Freeman et a1 (1985) using a different technique.…”

We have reviewed 19 “body image” studies on anorexia nervosa and bulimia nervosa published recently. In general, eating disorder patients overestimate their body width more often than do normal controls and are usually more disparaging toward their body. However, we contend that it is unnecessary and unwarranted to envoke the term “body image disturbance” to explain these research findings. We suggest that further research in the area of “body disparagement” or the characteristic attitude of “weight phobia,” “fear of fatness,” or “pursuit of thinness” may be yet fruitful without this problematic concept. Theories are not true or false, they are fertile or sterile. —Claude Bernard. When I use a word, Humpty Dumpty said in rather a scornful tone, It means just what I choose it to mean. —Lewis Carroll.

“…For instance, those seeking treatment report higher levels of distress compared to those not seeking treatment [13,14] and patients who prefer more drastic weight reduction methods, such as surgery or appetite supressants, differ on psychological variables from those who prefer conventional treatments such as diet [15][16][17]. Although body image distortion is a major diagnostic component in eating disorders there is no uniform description of its relation to obesity [18]. Furthermore findings about body image distortion in obese patients are controversial, with some studies showing overestimation, others underestimation, and others no difference when compared with controls [18][19][20].…”

Morbid obesity (defined as a body mass index (BMI) >40) is a severe and increasingly prevalent condition in developed countries. On top of medical dysfunctions a large proportion of these patients also suffer from psychosocial dysfunctions and psychiatric disorders. Prior to bariatric surgery a substantial percentage of patients suffer from binge eating disorder or binge eating symptoms. Surgery is carried out not only to reduce short term morbidity and mortality in patients with morbid obesity but it also gives a chance for a long-term weight loss. To achieve this goal many patients need some kind of psychiatric intervention. Objective:The principal aim of this study is to evaluate the impact of bariatric surgery on psychiatric disorders and psychological dysfunctions of patients with morbid obesity over the course of a year following surgery. Special consideration is given to the presence of psychiatric comorbidity, eating disorders, body image dissatisfaction and self-esteem.Design: Longitudinal, psychiatric intervention previous and one year after surgery. Results:The mean age of the patients was 41.7 years (SD=2.4) The mean weight was 121.8 kg (22.5) which corresponds to a mean BMI of 45.7 (7.7). The sex distribution is 20% male and 80% female patients. Psychiatric disorders (ICD-10 criteria), were present in 32.5 %. Among them eating disorders were the most prevalent (38.5%). Following bariatric surgery there was a significant improvement in eating disorders and eating symptoms (according to the Eating Disorders Inventory and the Bulimic Test of Edimburgh) and in body image satisfaction (measured by BSQ) and self steem (Rosemberg). A multiple regression analysis of clinical factors associated to weight loss showed that 40% of it is determined by the decrease of bulimic symptoms detected by the BITE-symptoms. Conclusion:Morbid obesity is a risk population for psychiatric disorders and psychological dysfunctions. Bariatric Surgery reduces over one year the severity of this morbidity. The impact of increased self-esteem through the increase of body image satisfaction and of the increase in control over food intake seems to be the major factor in these changes.
