Prevalence of three bulimia syndromes in the general population

International Journal of Advanced Research, 2020

Purpose: The study examines the prevalence of Bulimia nervosa in students at King Abdulaziz University in Saudi Arabia.Bulimia nervosaisan eating disorder characterized by consumption of large amounts of food by an individual followed by an attempt such as self-induced vomiting, long periods of exercising, and diuretics to avoid gaining weight. Patients and Method: The study adopted a cross-sectional survey among King Abdulaziz University students in Saudi Arabia. A sample of 499 comprising 357 females and 142 males was randomly selectedparticipants—the age of the sample population aged between 20 to over 55 years. The participants filled questionnaires about eating behavior, smoking, body image, and psychiatrist disorders. The height and weight of the sample population were taken, and their BMI was established. Results: Based on our statistics, the prevalence of bulimia nervosa among the male was 0.3%, and that of the female was 1.4%. ...

Little is known about the epidemiology of bulimia nervosa outside clinical settings. We report the incidence, prevalence and outcomes of bulimia nervosa using for the first time a nationwide study design.

This study examined the DSM-5 severity criterion for bulimia nervosa (BN) based on the frequency of inappropriate weight compensatory behaviors. 199 community volunteers classified with BN were categorized using DSM-5 severity levels and compared on demographic and clinical variables. 77 (39%) participants were categorized as mild, 68 (34%) as moderate, 32 (16%) as severe, and 22 (11%) as extreme. The severity groups did not differ significantly in demographic variables or body mass index. Shape and Weight concerns did not differ significantly across severity groups. Binge eating differed with the extreme group having significantly higher frequency than the severe, moderate, and mild groups, which did not differ from each other. Restraint differed with the extreme group having significantly higher levels than the mild group. Eating concerns differed with the extreme group having significantly higher levels than moderate and mild groups. Depression differed with the extreme group hav...

To investigate the incidence and correlates of bulimic behavior, 1268 high school females were surveyed. A 47-item questionnaire was used to identify a group of students that would meet the DSM-III criteria for a probable diagnosis of bulimia. Students were then compared across the four content areas of demographics; body perception and weight information; dieting, exercise and menstrual behavior; and frequency of bingeing and purging behavior. Results indicated that 4.9% of the students met rigorous criteria for the diagnosis of bulimia. Between-group comparisons indicated that body dissatisfaction, drive for thinness, and chronicity of dieting differentiated the two groups.

In the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnostic threshold for binging and compensation in bulimia nervosa (BN) decreased from twice to once weekly for 3 months. This study investigates the validity of this change by examining whether BN patients and those whose diagnoses "shift" to BN with DSM-5 are similar in their psychological functioning. EDNOS patients whose symptoms met DSM-5 BN criteria (n = 25) were compared to DSM-IV BN patients (n = 146) on clinically relevant variables. No differences were found on: BMI; weight-based self-evaluation; perfectionism; depression and anxiety symptoms; or readiness for change. Differences were found on one Eating Disorder Inventory subscale (i.e., bulimia), with the BN group reporting higher scores, consistent with group definitions. These findings support the modified criteria, suggesting that psychopathology both directly and indirectly related to eating disorders is comparable between those with once weekly versus more frequent bulimic episodes.

Background. Recent epidemiological data suggest a decline in bulimia nervosa (BN) incidence in primary care. We sought to examine BN point prevalence from 1982 to 2002 in a college population. , 800 women and 400 men were randomly sampled from a university for a study of health and eating patterns. Participation rates were 72 % in women and 63 % in men, resulting in n=2491 participants.

We sought to further explore the validity of the distinction between objective bulimic episodes (OBEs) and subjective bulimic episodes (SBEs) in the study of bulimic-type eating disorders. Drawing on data obtained at the second, interview phase of a large-scale epidemiological study, we identified mutually exclusive subgroups of women with bulimic-type eating disorders who engaged in regular OBEs but not SBEs (n ¼ 37) or regular SBEs but not OBEs (n ¼ 52). These subgroups were compared on a wide range of outcomes, including socio-demographic characteristics, current levels of eating disorder psychopathology, general psychological distress and impairment in role functioning, current and lifetime impairment in quality of life specifically associated with an eating problem, (self)-recognition of an eating problem, health service utilization and use of psychotropic medication. The only difference between groups was that participants who reported regular OBEs were heavier than those who reported regular SBEs. The findings converge with those of previous research in suggesting that bulimic-type eating disorders characterized by regular SBEs, but not OBEs, do not differ in any clinically meaningful way from those characterized by regular OBEs, but not SBEs. Inclusion of bulimic-type eating disorders characterized by regular SBEs as a provisional category requiring further research in DSM-V appears warranted.

SynopsisThis study compares rates of comorbidity of lifetime psychiatric disorder in a clinical sample of women with bulimia, with general population base rates, and with rates of comorbidity among bulimic women in the general population. Eighty-four per cent of the clinical sample of bulimic women had a lifetime affective disorder, and 44% a lifetime alcohol or drug disorder. These rates of disorder were significantly higher than the base rates in the general population. Bulimic women in the general population also had more affective and substance-use disorders than the general population base rates, but the rates of these disorders were lower than found in the clinical sample. In the general population, quite similar rates of other disorders including generalized anxiety, panic, phobia and obsessive–compulsive disorder, are found among those with bulimia, substance-use disorder and depression. Furthermore, among those with depression and substance-use disorder in the general popul...

We reviewed the literature on the course and outcome of bulimia nervosa. Longer-term outcome is associated with a considerable degree of relapse and chronification. Diagnostic crossover to anorexia nervosa and binge eating disorder is low. Mortality in bulimia nervosa is considerably lower than in anorexia nervosa. Social adjustment and sexuality apparently normalizes in quite a few bulimic women over the course of time. A large group of bulimic pa-tients, however, chronifies and suffers from severe bulimic symptoms and social and sexual impairment.
