Dissimilarities in eating attitudes,body image distortion,depression, and self-esteem between high-intensity male runners and women with bulimia nervosa

It has been suggested that high-intensity exercise regimens in males bear a resemblance to the features of eating disorders and that male runners may resemble women with anorexia nervosa and bulimia nervosa with regard to eating and weight attitudes, negative body image, and negative psychological adjustment. Twenty high-intensity male runners were compared with 20 sedentary-moderate exercising male controls and 20 women with bulimia nervosa. Compared with the bulimia nervosa subjects, the male runners were not anxious about eating, overly preoccupied with food, excessive in binge-eating or purging behavior, negatively preoccupied with their weight, intent on losing weight, high on personality traits presumed to underlie eating disorders, nor depressed or low in self-esteem. The male groups of high-intensity runners and controls were not significantly different on any measure. These results suggest that high-intensity exercising in males is not analogous to anorexia nervosa and bulimia nervosa.     

Males with anorexia nervosa: a controlled study of eating disorders in first-degree relatives

OBJECTIVE: To compare lifetime rates of full and partial anorexia nervosa and bulimia nervosa in first-degree relatives of males with anorexia nervosa and in relatives of never-ill comparison subjects. METHODS: Rates of eating disorders were obtained for 747 relatives of 210 probands from personal structured clinical interviews and family history. Best-estimate diagnoses were determined blind to proband diagnosis and pedigree status. RESULTS: Full and partial syndromes of anorexia nervosa aggregated in female relatives of ill probands. For the full syndrome of anorexia nervosa, the crude relative risk was 20.3 among female relatives and for partial syndrome anorexia nervosa, the crude relative risk was 3.3. In contrast, bulimia nervosa was relatively uncommon among relatives of ill probands. CONCLUSION: Although anorexia nervosa in males is exceedingly rare, there is a pattern of familial aggregation that is highly similar to that observed in recent family studies of affected females. On the basis of these findings, there is no evidence that familial-genetic factors distinguish the occurrence of anorexia nervosa in the two sexes.     

An epidemiologic study of maladaptive eating attitudes in a Canadian school age population

Although cases of anorexia nervosa and bulimia are being seen increasingly by health care professionals, little data is available on the prevalence of these disorders in the general population of school age children. Using a validated eating attitude test (EAT), a total of 5150 students, aged 12–20, from public schools and one university in the Province of Manitoba were surveyed. Overall, 5% of males and 22% of females scored 30 or above on the scale, suggesting significant concerns and attitudes regarding eating. These concerns were somewhat higher in urban versus rural settings and seemed to increase between the ages of 12 and 13 and remain high thereafter. Many of the students who scored high on the EAT were overweight, suggesting that these attitudes or concerns are not specific to anorexia nervosa and/or bulimia.     

Lay beliefs about disordered eating

Although “disordered eating,” as a set of psychiatric conditions, implicitly evaluates components of a social phenomenon, little attention has been paid to the boundaries between socially accepted and abnormal eating. Lay knowledge and evaluations of the formal criteria for a diagnosis of anorexia nervosa or bulimia were therefore examined. The results show that although males and females know more about anorexia nervosa than bulimia, the DSM-III criteria for anorexia nervosa, which involve the determined pursuit of slimness and a body image disturbance, were judged by very few people to be both uncommon and abnormal. Bulimia, however, seems to be much closer to what is commonly judged to involve unusual behavior.     

Sociocultural influences on eating disorders in professional female ballet dancers

Fifty-five white and eleven black female dancers in nine regional and national ballet companies in America and Europe (mean age 24.9) were surveyed for eating disorders. The dancers, as a whole, weighed 12% below their ideal weight for height. None of the black American dancers reported anorexia nervosa or bulimia, while 15% of the white American dancers reported anorexia nervosa and 19% reported bulimia. All instances of anorexia nervosa were in national rather than regional companies, making the incidence among whites in the former 22%. Self-reported anorectics scored higher on the EAT-26, had lower weights, exhibited more psychopathology, and a poorer body image than the nonanorectics. In addition, all but one of the self-reported anorectics weighed, or had weighed, less than 20% of ideal weight for height. The bulimics valued their careers less, dieted more, and exercised less frequently than the nonbulimics. Weight did not differ for these two groups. The data suggest that the anorectic dancers differ from dancers with no eating disorders and that sociocultural factors are related to the report of eating disorders. Specifically, level of competition is related to reported anorexia nervosa and ethnicity to anorexia nervosa and bulimia.     

Dating People with Anorexia Nervosa and Bulimia Nervosa: Attitudes and Beliefs of University Students

ABSTRACT

Attitudes and beliefs about dating people with eating disorders were investigated in men and women using a questionnaire administered to 752 university students. Students believed that people with anorexia nervosa and bulimia nervosa had a difficult time dating, dates would involve conflict, and dating would be a negative experience. Students were more comfortable in casual interactions than more serious dating activities with people with anorexia nervosa and bulimia nervosa. Men were somewhat comfortable dating people with anorexia nervosa or bulimia nervosa, but less so for obesity. Most students believed dating people with anorexia nervosa and bulimia nervosa would not be a positive experience, and men Stigmatized people with eating disorders differently, than did women.     

Selective processing of linguistic and pictorial food stimuli in females with anorexia and bulimia nervosa

PURPOSE: This study investigated subjects with eating disorders' selective attention to linguistic and pictorial representations of food stimuli in a version of the Stroop color-naming task. If subjects with eating disorders' attention really are biased by food stimuli, one would expect equally delayed color-naming latencies to food pictures as previous studies have found to food words. METHOD: Twenty females with eating disorders (anorexia nervosa, bulimia nervosa, or a combination of both) and 24 female controls identified the color of Stroop versions of linguistic and pictorial representations of color, food, emotional, and neutral stimuli. RESULTS: The eating disorder group was slower than the controls in identifying the color of all words (including the food words) and the pictures depicting food stimuli (but not any of the other pictures). The eating disorder group was also slower in identifying the color of both food and emotional than neutral stimuli, both for the linguistic and pictorial stimuli. CONCLUSION: These findings indicate that females with bulimia and anorexia nervosa's biased attention to food stimuli are not restricted to linguistic representations. The delayed responses to the emotional words and pictures suggest that processing of negative emotional stimuli, in addition to dysfunctional concerns about stimuli related to food and eating, is important in the maintenance of eating disorders.     

Nutritional knowledge in patients with eating disorders

A questionnaire was developed to measure main areas of nutritional knowledge. Fifty-six patients with DSM-III diagnoses of anorexia nervosa, bulimia, or atypical eating disorders and 144 normal controls completed the questionnaire. Item analyses of a condensed form of the original instrument indicated satisfactory reliability of total scale and subscales. Patients with anorexia nervosa or bulimia had significantly higher mean scores for nutritional knowledge than controls on subscales “Macronutrients and Roughage” and “Calories” but did not differ from them on the subscale “Micronutrients and Vitamins.“ Patients with bulimia and patients with anorexia nervosa had equivalent scores. About 15% of anorectic or bulimic patients scored below the 25th percentile of normal controls. Implications for dietary management in eating disorders are discussed.     

Eating disorders in adolescent boys: a review of the adolescent and young adult literature

Although a number of studies have investigated eating disorders in adolescence and the topic has been thoroughly reviewed, these studies have typically focused on females, only to state that the approach and treatment should be similar in males. Recently, there have been a number of studies that have explored gender differences in eating disorders. In this article, we review the literature pertaining to two DSM-IV-defined disorders (anorexia nervosa and bulimia nervosa), a DSM-IV-defined research disorder (binge eating disorder), and two DSM-PC-defined disorders (dieting/body image and purging/binge-eating behaviors), highlighting those findings that pertain to disordered eating in adolescent boys.     

Caffeine intake in eating disorders

OBJECTIVE: The current study compares caffeine consumption in females with an eating disorder and females without an eating disorder. METHOD: Caffeine intake in three diagnostic groups (10 females with anorexia nervosa, 27 females with bulimia nervosa, and 42 females with binge eating disorder [BED]) was compared with caffeine intake in three comparison groups (n = 659 each). Data were obtained from a longitudinal study of Black and White girls. Three-day food records were examined for the years before the onset of the eating disorder, the onset year, and the years after the onset of the eating disorder. Data from the same years were used for the comparison groups. RESULTS: Caffeine intake increased over time between ages 9 and 19 years across all groups and this trend was not moderated by diagnostic status. For anorexia nervosa, relative to the non-eating disorder group, the proportional intake of caffeine from soda increased significantly before onset to onset to after onset and ingestion of chocolate-containing foods decreased sharply over time. CONCLUSION: Caffeine consumption in young girls with eating disorders differs from girls with no eating disorders only for anorexia nervosa, but not for bulimia nervosa or BED.     

Atypical eating disorders.

Some patients with eating disorders have neither anorexia nervosa (A.N.) nor bulimia. Cases which do not rigorously meet the DSM-III-R criteria for anorexia nervosa or for bulimia are usually defined as "eating disorders N.O.S." Among them are patients with pathological characteristics very closely related to the above-mentioned categories. Others, however, although affected by an eating disorder, present a quite different clinical picture from either A.N. or bulimia. In a study of 80 eating disorder cases, only 45 met the strict definition of A.N. or bulimia. The other 35 were diagnosed as atypical eating disorders and are the focus of this presentation. 29 were classified as Eating Disorders N.O.S. and 6 as obesity. Co-morbidity, gender and age data, and clinical vignettes are presented.     

The current status of treatment for anorexia nervosa and bulimia nervosa

A survey investigating the current status of treatment for anorexia nervosa and bulimia nervosa was distributed at the International Conference on Eating Disorders in 7988 and again in 1990. Respondents answered questions regarding treatments they had endorsed for their last patient with anorexia nervosa and for bulimia nervosa. One hundred and seven medical doctors and psychologists completed the survey in 1988 and 115 in 1990. The results indicate that: (1) less than 50% of the respondents believe there is a consensus regarding the treatment of eating disorders; (2) talking therapy is overwhelmingly endorsed for the treatment of both anorexia and bulimia nervosa; (3)there is a trend in clinical practice towards using drug therapy more frequently in treating patients with bulimia nervosa than in treating patients with anorexia nervosa; (4)physicians are more likely than psychologists to endorse drug therapy when treating patients with anorexia and for bulimia nervosa; and (5) about one third of the respondents endorse drug therapy for treating anorexia nervosa. © 1992 John Wiley & Sons, Inc.     

Review of the prevalence and incidence of eating disorders

OBJECTIVE: To review the literature on the incidence and prevalence of eating disorders. METHODS: We searched Medline using several key terms relating to epidemiology and eating disorders and we checked the reference lists of the articles that we found. Special attention has been paid to methodologic problems affecting the selection of populations under study and the identification of cases. RESULTS: An average prevalence rate for anorexia nervosa of 0.3% was found for young females. The prevalence rates for bulimia nervosa were 1% and 0.1% for young women and young men, respectively. The estimated prevalence of binge eating disorder is at least 1%. The incidence of anorexia nervosa is 8 cases per 100,000 population per year and the incidence of bulimia nervosa is 12 cases per 100,000 population per year. The incidence of anorexia nervosa increased over the past century, until the 1970s. DISCUSSION: Only a minority of people who meet stringent diagnostic criteria for eating disorders are seen in mental health care.     

Attitudes and knowledge regarding bulimia and anorexia nervosa

The current study investigated general knowledge of the symptoms, causes, and treatment of bulimia and anorexia nervosa, as well as attitudes toward anorexics and bulimics. High school and college students, 15 to 25 years of age, were administered an anonymous questionnaire. Adequate definitions of bulimia and anorexia were provided by 44% and 71% of the subjects, respectively. Females demonstrated more knowledge than did males. Emotional problems were seen as the most likely cause of both disorders, and psychotherapy was considered the most effective treatment. The subjects were more rejecting of an anorexic female, an obese female, and an average weight vomiter than an average weight binger. Over 4 7 % of the males were rejecting of an anorexic, obese, or purger female as a dating partner.     

Anorexia and Bulimia

ABSTRACT

Eating disorders are complicated mental illnesses that can have tremendous physical and psychological consequences. This article provides general information on the two most common eating disorders: anorexia nervosa and bulimia nervosa. It discusses the symptoms of these diseases, their effects, some of the factors in their development, and common forms of treatment. The article concludes with a bibliography of selected Internet resources that provide additional information on anorexia, bulimia, and other eating disorders.     

Season of birth and eating disorders: patterns across diagnoses in a specialized eating disorders service

OBJECTIVE: In view of inconsistent findings from previous studies, the aim was to investigate possible seasonal variation in month of birth in patients with anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified. METHOD: We examined the month of birth in a cohort of 1,305 adult patients with a DSM-IV eating disorder diagnosis at first presentation to a specialized eating disorders service. RESULTS: When compared to general population data, we found no evidence of significant variation in month or season of birth in anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified. CONCLUSION: The authors question whether people who develop eating disorders differ from the general population in their season of birth. Caution is expressed about further speculation regarding the etiological significance of season of birth in eating disorders.     

Racial and socioeconomic: Influences in anorexia nervosa and bulimia

Eight black and 120 white patients with anorexia nervosa or bulimia were compared with each other and with 21 black control patients. Biack and white patients with eating disorders were similar in demographic features (except for later age of onset in blacks), in clinical characteristics, and in course of illness. Both racial groups with eating disorders had a significantly higher socioeconomic status than control patients. A diagnosis of anorexia nervosa or bulimia can be confidently made independent of racial designation. Socioeconomic status appears to be a risk factor for development of anorexia nervosa or bulimia in both black and white populations.     

Athletes and eating disorders: the National Collegiate Athletic Association study.

OBJECTIVE: To present findings from a collaborative study with the National College Athletic Association regarding the prevalence of disordered eating among student athletes. METHOD: 1,445 student athletes from 11 Division 1 schools were surveyed using a 133-item questionnaire. RESULTS: Results indicated that 1.1% of the females met DSM-IV criteria for bulimia nervosa versus 0% for males. None of the student athletes met DSM-IV criteria for anorexia nervosa. 9.2% of the females were identified as having clinically significant problems with bulimia versus .01% of the males. 2.85% of the females were identified as having a clinically significant problem with anorexia nervosa versus 0% for males. 10.85% of the females reported binge eating on a weekly or greater basis versus 13.02% of the males 5.52% of the females reported purging behavior (vomiting, laxatives, diuretics) on a weekly or greater basis versus 2.04% for the males. DISCUSSION: Results from the current investigation are more conservative than previous studies of student athletes, but comparable to another large study of elite Norwegian athletes. Reasons for these differences are discussed. Clearly female athletes report more difficulty with disordered eating than male athletes. Some specific risk factors for female athletes are discussed.     

The psychiatric history of anorexia nervosa and bulimia nervosa: Weight concerns and bulimic symptoms in early case reports

British, French, American, German, and Italian historical medical reports on possible cases of anorexia nervosa and bulimia nervosa were critically reevaluated in order to trace the history of weight concerns, binge eating, and methods of food reversal like self-induced vomiting in these texts. It is argued that weight concerns are a new phenomenon in prolonged extreme fasting and has superseded traditional ascetic motivations for fasting from the first use of the term anorexia nervosa on. Binge eating, or bulimia as a symptom, on the other hand, has been known ever since ancient times; what is new here is its combination with methods of food reversal, which are motivated by concerns about weighing too much. This combination, bulimia nervosa (DSM-III-R), was first described in cases of primary anorexia and started becoming more frequent only in the 1940s. First accounts of possible cases of bulimia nervosa at normal body weight were published in the 1930s. Methodological problems of retrospective diagnosing and factors inherent to the history of medicine which might have influenced the history of medical writing about eating disorders are discussed.     

College students' mental models for recognizing anorexia and bulimia nervosa

Knowledge about eating disorders influences lay people's ability to recognize individuals with anorexia nervosa (AN) and bulimia nervosa (BN) and refer them to professional treatment. We assessed mental models (stored knowledge) of AN and BN in 106 college students. Results indicated that most students have general, but not specific, information about AN and BN's symptoms, consequences, causes, duration, and cures. They also believe that people with eating disorders tend to be young, White women. These findings suggest that lay recognition of eating disorders may be based primarily on observations of dysfunctional eating behaviors and therefore facilitated by additional knowledge.
