“…1 Bulimia is more frequent than anorexia, with a prevalence of 90 to 95% among females. 2 Although the prevalence of these disorders in the general population usually is quite lower, an increase in the number of new cases has been observed in men and women in all age groups.…”

Objective: To determine the prevalence of possible eating disorders and inappropriate eating behaviors in school children from six municipalities in the state of Minas Gerais, Brazil.Methods: Cross-sectional study. The Bulimic Investigatory Test of Edinburgh (BITE), Eating Attitude Test (EAT), and Body Image Test were applied to 1,807 public school students with age ranging from 7 to 19 years.Results: According to the EAT, 241 students (13.3%), mostly females, had inappropriate eating behaviors. Nineteen students (1.1%) had a BITE score indicating a possible diagnosis of bulimia nervosa. We found that 1,059 students (59%) were unhappy with their body image; 731 students (40%) were on a diet; and 1,014 (56%) exercised to loose weight. In addition, 218 students (12%) presented binge-eating and 175 students (10%) used purgative methods to control weight. Conclusions:We observed a high prevalence of possible eating disorders and inappropriate eating behaviors in the study population, especially among female adolescents. These results are similar to those reported for developed countries. The present findings are relevant for the clinical care of children and adolescents and can serve as the basis for future works aimed at increasing our understanding of the risk factors for these illnesses.

“…Fewer studies found age to be a significant predictor (3,13) than those that found it not predictive (4,9,47,51,53,59,60). In the two studies that found that age at study entry predicted outcome, one (13) found that older age predicted positive outcome, and the other (3) found that younger age predicted positive outcome.…”

“…In general, studies have not found comorbid axis I disorders at presentation to be predictive of outcome (11,17,47). Of the 18 studies assessing the predictive value of comorbid depression at presentation for outcome in bulimia nervosa, 14 (4,7,9,12,13,16,17,20,33,(47)(48)(49)(50)(51) found no association.…”

A lthough binge eating and purging were observed in women with anorexia nervosa, bulimia nervosa is a relatively recent addition to the medical literature, having been first described in 1979 (1). Consistent with the negative impact that binge eating and purging were observed to have on anorectic patients' outcome (2), bulimia nervosa was termed "an ominous variant of anorexia nervosa." This dire description was tempered with the recognition that "only a brief comment on the prognosis of bulimia nervosa is appropriate, for long-term follow-up studies have not been undertaken" (1). Now, more than 15 years later, little additional information seems available. A single study of 44 women diagnosed with bulimia nervosa 10 years earlier (3) provides the only available data on long-term outcome. Indeed, DSM-IV states, "The long-term outcome of Bulimia Nervosa is not known."Comparing and summarizing results across those outcome studies which do exist are complicated by methodological differences among and within studies. For example, one study (4) employed four different measures of eating disorder outcome in order to attribute differences in recovery estimates to the impact of assessment methods. That study found that the range of those considered recovered was 29% to 42%. Thus, inconsistent findings across studies may be partially attributed to differences in methods of assessment, as well as sample characteristics, definitions of terms, and ascertainment rates.The limited availability and comparability of research findings leave the following questions largely unanswered: What is the long-term physical, psychological, and psychosocial outcome among women diagnosed with bulimia nervosa? What percentage of women re-

Objective A systematic epidemiological comparison of body weights of patients with anorexia nervosa can be enhanced by the use of age percentiles for the body mass index. Method: To demonstrate the feasibility of this approach, body mass indices of 81 female adolescents with anorexia nervosa were calculated from anthropometric data upon admission for inpatient treatment and at follow‐up and set into relationship to the age‐dependent distribution of the body mass index in a large and representative sample of the German population. The percentiles were used to visualize the weight increase over time of each former patient by aligning the body mass index at referral with the respective body mass index at follow‐up. Results: Upon admission most adolescents had body mass indices below the third age centile. The distribution of body mass indices at outcome suggests a continuum between death of complications related to starvation, chronic anorexia, residual anorexia, and a low body weight. Patients with very low body weights at referral had a poor prognosis, because their body weights tended to remain below the minimal normal weight for height. These conditions were statistically best described by categorial analysis, because they were nonlinear to a certain extent. Discussion: The results indicate that the body mass index at referral influences the amount of weight that an individual patient gains in the future. © 1996 by John Wiley & Sons, Inc.
