The prevalence of eating disorders among university students and the relationship with some individual characteristics

OBJECTIVE: The purpose of this study was to determine the prevalence of eating disorders (EDs) among university students in a rural area of Turkey and to compare groups based on the sociodemographic data, history of child abuse and neglect, family roles and self-esteem with a normal control group regarding EDs. METHOD: Subjects who were chosen by simple random sampling method were consisted of 980 Cumhuriyet University students who agreed to participate out of the 1003 total students and were given a sociodemographic information form and an Eating Attitudes Test (EAT). Students who scored above a cutoff level on the EAT were interviewed using the Structured Clinical Interview for DSM-IV axis I Disorders (SCID-I), Clinical Version. The Rosenberg Self-Esteem Scale, Family Assessment Device (FAD) and Childhood Abuse and Neglect Questionnaire Form were given to subjects in the control and study groups. RESULTS: Seventy-one of the 951 students (492 female, 459 male) who correctly filled out the EAT had a score above the cutoff level of 30 or higher. Of these 71 students, 21 (2.20%) were found to have an eating disorder based on the SCID-I. No subjects were found to have anorexia nervosa. Eighteen of the 21 subjects were female. Of these 18 female students, 15 (1.57%) were found to have bulimia nervosa and three (0.31%) were found to have binge eating disorder (BED). All of the three male subjects were diagnosed with BED (0.31%). The self-esteem of those in the study group was lower than those in the control group (p < 0.001). Subjects in the study group had more frequent histories of sexual and emotional abuse in childhood (p < 0.05). Also, in the study group scores showing communication in FAD families, unity and emotional attachment were statistically significantly lower than the control group (p < 0.001). CONCLUSIONS: It has been observed from the results of this research that the frequency of bulimia nervosa and BED in this sample is so similar to Western samples. Besides that, self-esteem, child abuse and neglect, and family functions must be examined in detail because they are risk factors for EDs and affect the course of treatment.     

Full-syndrome,partial-syndrome and subclinical eating disorders: an epidemiological study of female students in Southern Italy

We screened a sample of 919 female students, aged 13–19 years, by means of the EDI 2 and GHQ-28 questionnaires. Those students identified as being at risk for an eating disorder (281 subjects) underwent a psychiatric interview. We found 2 cases of full-syndrome anorexia nervosa (0.2%), 21 cases of full-syndrome bulimia nervosa (2.3%) and 2 cases of full-syndrome binge-eating disorder (0.2%). Moreover, 35 girls (3.8%) met the criteria for partial-syndrome and 98 girls (10.7%) fulfilled the criteria for subclinical eating disorders. Subjects with partial-syndrome and subclinical eating disorders had higher scores than those with no diagnosis, but lower scores than students with full-syndrome eating disorders, on both the EDI 2 and GHQ-28 questionnaires. A follow-up of subjects with partial-syndrome and subclinical eating disorders is now in progress.     

Screening disordered eating attitudes and eating disorders in a sample of Turkish female college students

It has been hypothesized that college women are particularly susceptible to the development and maintenance of disturbed eating behaviors. The purpose of this study was to determine the frequency of disordered eating attitudes and eating disorders in a sample of Turkish female college students. The Eating Attitudes Test was administered to a sample of 414 female college students. The subjects who had a score of 30 or higher were accepted as having disordered eating attitudes, and all of them have been examined using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition for eating disorders. Of the overall sample, 17.1% of subjects were classified as having disordered eating attitudes. This subgroup of subjects was then compared with the remainder on all the other measures. The differences between students with disordered eating attitudes and those without on sociodemographic variables (except for age) were not statistically significant. The rate was 1% for eating disorders including anorexia nervosa (0.5%) and bulimia nervosa (0.5%). This study suggested that the prevalences of disordered eating attitudes and anorexia nervosa among female college students in Turkey were similar to those found in Western societies, but the rate for bulimia nervosa was lower compared with Western societies.     

Insulin-dependent diabetes mellitus and eating disorders: a prevalence study

There have been numerous reports in the recent literature suggesting a relationship between diabetes mellitus and the eating disorders. In the current investigation, 97 pediatric diabetes patients were administered a modified version of the Eating Habits Questionnaire, which included items specific to diabetes mellitus based on DSM-III-R criteria. None of this sample were diagnosed as anorexic and only one patient was diagnosed as currently bulimic. Possible reasons for the higher prevalence rates reported for other samples are discussed.     

Prevalence, comorbidity, and correlates of DSM-IV axis I mental disorders among female university students

This cross-sectional study evaluated the prevalence of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), axis I mental disorders among Spanish female students and investigated their psychiatric comorbidity and correlates. 1054 female students with a mean age of 22.2 years were randomly selected, with stratification by academic seniority and the type of academic discipline. The cases of mental disorder were identified by clinically trained interviewers with the aid of the Structured Clinical Interview for DSM-IV Axis I Disorders-Clinician Version. The lifetime prevalence of the targeted psychiatric disorders was 50.8%, and its point prevalence was 37.3%. The commonest disorders were nicotine dependence, depression, and generalized anxiety disorder. Nearly 37% of subjects with a psychiatric disorder had two or more diagnoses. Mental illness was associated with family income, financial independence, type of academic discipline, violence from men, social support, and self-esteem. Psychiatric disorders are common among female university students. Serious attention should be paid to preventive and therapeutic programs in this group.     

Migraine prevalence in eating disorders and pathophysiological correlations

Acute hemorrhagic leukoencephalitis (AHL) is a rare demyelinating disease mainly affecting children, characterized by acute onset, progressive course and high mortality. A 62-year-old man was admitted to our Unit for diplopia and ataxia ensuing 2 weeks after the onset of pneumonia. MRI T2-weighted images showed signal hyperintensities in the brainstem. Antibodies against Mycoplasma Pneumoniae and cold agglutinins were found. Two weeks later the patient had a worsening of his conditions: he developed left hemiplegia with motor focal seizures and the day after he was deeply comatose (GCS = 4). A second MRI scan showed extensive hyperintensities involving the whole right hemisphere white matter with a small parietal hemorrhagic area. The clinical and neuroimaging features suggested the diagnosis of AHL, Aciclovir in association with steroid therapy were administered and then plasmapheresis was started. After 30 days of coma, the patient gradually reacquired consciousness and motor functions; anyway a left hemiplegia persisted.     

Current and lifetime prevalence of obsessive compulsive disorders in eating disorders

A significant proportion of patients suffering from Eating Disorders (ED) present a comorbidity with anxiety disorders. Among the anxiety disorders, Obsessive Compulsive Disorders (OCD) are the third most frequently diagnosis observed in ED. However, prevalence rates from the literature are contradictory depending on the diagnostic criteria and evaluation tools used. Studies concerning the chronology of appearance of OCD and ED and the role played by denutrition are even rarer and equally contradictory. OBJECTIVE: The aim of this study is to bring new empirical data to the study of the correlations between OCD and ED by exploring, in a significant clinical sample, the current and lifetime OCD comorbidity in the diagnostic sub-groups and sub-types of ED as defined by the DSM IV and to study the chronology of appearance of these disorders taking into account the role played by denutrition. We make the assumption that there should be a difference in the prevalence of obsessive compulsive disorders in the various ED sub-groups and sub-types and that purging anorexics should, at equivalent levels of denutrition, exhibit higher OCD prevalence rates than the other sub-types as a result of their more severe general psychopathology. METHODS: Current and lifetime prevalence were investigated using the Mini International Neuropsychiatric Interview (MINI) and the Yale-Brown Obsessive Compulsive Scale in a sample of 89 DSM IV eating disorders in and out-patients aged between 15 and 30 (58 AN and 31 BN) and 89 matched controls. In order to increase the validity of the current diagnosis of OCD only patients presenting an OCD diagnosis on the MINI (excluding obsessions and compulsions related to food and body image) and a score of 16 or more on the Y-BOCS were included in the study. RESULTS: Current and lifetime prevalence of OCD in ED is significantly higher than in general population (15.7% and 19% vs 0% and 1.1%, p < 0.05). Anorexic and bulimic patients do not show any difference in the current and lifetime comorbidity (19% and 22.4% vs 9.7% and 12.9%, ns). Concerning the diagnostic sub-types, following our assumption purging anorexics present the higher current and lifetime prevalences (29% and 43%), followed by restrictive anorexia (16%) and purging bulimia (13%). The only significant difference is found in the lifetime prevalence of OCD between purging and non purging anorexics. In the great majority of cases (65%) OCD diagnosis precedes ED diagnosis and OCD current prevalence and Y-BOCS scores of underweight patients are not significantly higher than normal weight patients, suggesting that there are only limited links between denutrition and obsessionality. LIMITS: Some methodological limitations must be considered. First of all, the small sample size of the diagnostic sub-types of ED do not enable us to draw definitive conclusions concerning the prevalence of OCD in the clinical forms of ED. Some of the diagnostic sub-types of ED, as BN-NP, appear at different ages: in order to better investigate the prevalence of OCD in all the diagnostic sub-types, larger age ranges should be considered. Secondly, our sample of anorexics is almost made of hospitalized inpatients recrutated in a specialized university unit, whereas bulimics are all consulting outpatients. It is possible that the higher than normal rates of OCD in anorexics could be related to the severity of this sample. Comparisons with samples of consulting anorexics should be performed. Lastly, it is necessary to evoke the limitation represented by the choice of a healthy control group. OCD are rare in the general population and the differences found between the clinical and the control groups do not offer strong arguments to support the specificity of the association between OCD and ED, which would be better explored by using a pathological control group. CONCLUSIONS: So far, none of the various models proposed to explain the comorbidity observed between ED and OCD appears completely satisfactory. ED and OCD would share a genetic vulnerability to a dysregulation of serotoninergic functioning which would predispose these subjects, depending on specific clinical and biological conditions, to develop an obsessional and compulsive symptomatology more or less focused on food and body image. The knowledge of the clinical and biological specificities of the ED diagnostic sub-types presenting an OCD comorbidity could point the way towards specific therapeutic interventions in these patients. Our study of the comorbidity of OCD in ED makes a further contribution to the identification of specific links between the OCD and the various clinical forms of ED. More clinical and biological studies are needed to further explore these relationships.     

Migraine prevalence in eating disorders and pathophysiological correlations

The eating disorders (ED): anorexia nervosa (AN) and Bulimia nervosa (BN) are severe psychiatric and somatic conditions occurring mainly in young woman. Although the etiology is largely unknown, same evidences suggest that biological and psychological factors play a relevant role in the pathogenesis, along with monoamine, indole and same hypothalamic hormonal dysfunctions. Migraine is characterized by similar metabolic and psychological anomalies suggesting that a possible relationship exists between the two pathological conditions. In order to understand the possible relationship between migraine and ED, we have investigated the prevalence of migraine and the other primary headaches in a large group of AN and BN patients. In addition, we have studied the role of tyrosine metabolism in the same group of AN and BN young woman sufferers. In particular, we measured plasma levels of elusive amines: tyramine (Tyr) and octopamine (Oct) and catecholamines: noradrenalin (NE), dopamine (DA). The results of this study show that the prevalence of migraine in the woman affected be EA is very high (>75%). The levels of Tyr and DA were higher and levels of NE were lower in the ED patients with respect to the control subject. These biochemical findings suggest that abnormalities of limbic and hypothalamic circuitries play a role in the pathogenesis of ED. The very high prevalence of migraine in our group of ED sufferers and the biochemical profile of migraine, similar to that ED patients have shown in this study, suggest that migraine may constitute a risk factor for the occurrence of ED in the young females. This hypothesis is supported by the onset of migraine attacks that initiated, in the majority of the patients, before the occurrence of ED symptoms.     

The prevalence of personality disorders among those with eating disorders

The genuine prevalence of personality disorders among those with eating disorders is unknown. However, in this paper, we summarize the existing data, with careful acknowledgment of our approach to interpretation as well as the limitations of previous studies. Our findings indicate that obsessive-compulsive personality is the most common personality disorder in restricting-type anorexia nervosa, while borderline personality is the most common personality disorder in binge-eating/purging type anorexia nervosa. Borderline personality is the most common personality disorder in bulimia nervosa, as well. In those with binge eating disorder, obsessive-compulsive personality is the most common personality disorder although, compared with the preceding eating disorder diagnoses, there are broader clusters of personality disorders represented in this group. We discuss the implications of these findings.     

A systematic review of studies of depression prevalence in university students

Background

Depression is a common health problem, ranking third after cardiac and respiratory diseases as a major cause of disability. There is evidence to suggest that university students are at higher risk of depression, despite being a socially advantaged population, but the reported rates have shown wide variability across settings.

Purpose

To explore the prevalence of depression in university students.

Method

PubMed, PsycINFO, BioMed Central and Medline were searched to identify studies published between 1990 and 2010 reporting on depression prevalence among university students. Searches used a combination of the terms depression, depressive symptoms, depressive disorders, prevalence, university students, college students, undergraduate students, adolescents and/or young adults. Studies were evaluated with a quality rating.

Results

Twenty-four articles were identified that met the inclusion and exclusion criteria. Reported prevalence rates ranged from 10% to 85% with a weighted mean prevalence of 30.6%.

Conclusions

The results suggest that university students experience rates of depression that are substantially higher than those found in the general population. Study quality has not improved since 1990.     

Dependency and eating disorders in female psychiatric inpatients

Research indicates that oral dependent and eating-disordered individuals have similar personality traits, attitudes, and behaviors, suggesting that dependency may be a factor in the dynamics of anorexia and bulimia. To investigate this issue, we compared the proportions of dependent and food-related percepts in the Rorschach protocols of matched samples of eating-disordered (N = 16), obese (N = 18), and non-eating-disordered, normal-weight female psychiatric inpatients (N = 17). Eating-disordered patients reported significantly more dependent Rorschach imagery than did obese or normal-weight control patients, but no difference in the proportion of food-related imagery was found among the three groups. These results support the hypothesis that unresolved dependency issues underlie anorexia and bulimia.     

The prevalence of personality disorders in 210 women with eating disorders.

BACKGROUND: The purpose of this study was to assess the prevalence, reliability, and predictive value of comorbid personality disorders in a large sample of 210 women seeking treatment for anorexia nervosa (N = 31), bulimia nervosa (N = 91), or mixed disorder (N = 88). METHOD: All subjects were interviewed using the Structured Interview for DSM-III Personality Disorders as part of a longitudinal outcome study of eating disorders currently underway at Massachusetts General Hospital. RESULTS: Of the 210 subjects, 27% had at least one personality disorder; the most commonly observed was borderline personality disorder in 18 subjects (9%). The highest prevalence of personality disorders was found in the anorexia nervosa/bulimia nervosa group at 39%, followed by 22% in the anorexics and 21% in the bulimic sample. We found statistically significant differences regarding the distribution of personality disorders across eating disorder groups. The dramatic personality disorder cluster was differentially distributed across groups; this finding was accounted for by higher rates of borderline personality disorder in the bulimia nervosa and anorexia nervosa/bulimia nervosa groups than in the anorexia nervosa group. The anxious personality disorder cluster was differentially distributed across groups with higher rates in the anorexia nervosa and anorexia nervosa/bulimia nervosa samples. Those subjects with a comorbid personality disorder had a significantly slower recovery rate than those without a comorbid personality disorder. CONCLUSION: The prevalence of personality disorders is not high in treatment-seeking women with eating disorders compared with previously studied samples. The greatest frequency of comorbid personality disorders is in the anorexia nervosa/bulimia nervosa group; this subset also had longer duration of eating disorder illness and much greater comorbid Axis I psychopathology compared with the rest of the sample. Future studies should address whether personality disorders have predictive value in the long-term course and outcome of eating disorders.     

High prevalence of eating disorders not otherwise specified in northwestern Spain: population-based study

Purpose

To determine the incidence and prevalence of eating disorder and its clinical forms.

Methods

All new ED cases of both genders, ≥15?years old, diagnosed from January 2005 to December 2009 were included. All patients who suffered from ED in December 2009 were included in the prevalence study. This is a prospective, population-based study. Cumulative incidence rates and 20-year prevalence were calculated.

Results

The ED incidence was 14.1 (95% CI 11.4–16.1) cases per 100,000 inhabitants per year, for AN, BN and EDNOS 3.1 (95% CI 2.00–4.1), 4.4 (95% CI 3.0–8.00) and 6.5 (95% CI 4.8–7.9), respectively. The incidence of ED at the four age-intervals, 15–24, 25–34, 35–45 and >45?years, revealed that the 25–34-year interval had the highest incidence; moreover, new cases were observed even in the >45-year interval. The prevalence of ED was 82.8 (95% CI 69.4–94.5) per 100,000 inhabitants, being for AN, BN and EDNOS 18.6 (95% CI 12.5–24.4), 25.7 (95% CI 18.5–32.5) and 38.3 (95% CI 29.4–46.5), respectively.

Conclusions

The incidence and prevalence of EDNOS are the highest in the ED cases; furthermore, new cases of ED are observed above the age of 45, which are remarkable data.     

Differences between female and male patients with eating disorders--results of a multicenter study on eating disorders (MZ-Ess)

Publications about men with eating disorders are still rare. Therefore, in view of the current status of the findings, it seems worthwhile to examine the differences that are empirically verified as well as the relevant common features between the sexes. Based on a representative sample, therefore, male and female patients with eating disorders in inpatient treatment are compared in terms of demographic and clinical variables (symptoms and personality), both at the beginning of treatment and two-and-a-half years after the inpatient treatment, and the findings are discussed with regard to their "gender specificity". The study covered 1,171 patients (male and female) with the diagnosis criteria for anorexia, bulimia and double diagnosis according to DSM-III-R; 33 of them were men. Anorexia cases (342 women and 13 men) and bulimia cases (629 women and 18 men) were compared at the beginning of treatment with the following instruments: Symptom Checklist 90-R; Eating Disorder Inventory; questionnaire for the symptom diagnosis of eating disorders; Freiburger Pers?nlichkeitsinventar and Narzissmus-Inventar. As a measure of success in the 2.5 year catamnesis (764 women and 20 men), operationalized criteria were defined using the LIFE. The 2.8 % share of men with eating disorders in inpatient treatment again confirms the special nature of this clinical disorder for men. An interesting result is the later onset of illness in male anorexia cases. Coinciding with comparable studies, there are only minor differences in eating behavior, but the differences in body experience are much more pronounced. In bulimic men, there is a higher percentage of homosexuals and they are more satisfied with their body. Anorectic men have a greater gain from the illness, are more concerned about their health and are less performance-minded than female anorectics. The differences that were found clearly indicate that these occur especially in the area of dealing with the body and the significance of the body. One of the reasons why the results in the area of personality and sexual identity are interesting is that they point to differences which definitely appear to be significant, not just between the sexes, but also between male anorexia and bulimia.     

Lifetime prevalence of eating disorders among professionals in the field

The purpose of this study was to assess whether professionals in the field of eating disorders have an increased lifetime prevalence of an eating disorder compared to the general population.     

The prevalence of eating disorders in adolescents with idiopathic scoliosis

This study examines the hypothesis of an association between adolescent idiopathic scoliosis (AIS) and eating disorders (EDs). A population of young females affected by AIS has been interviewed for a possible diagnosis of EDs. The proportion of individuals with EDs resulted significantly larger than normative epidemiological data: Prevalences were 9.2% for anorexia nervosa (AN), 7.7% for bulimia nervosa (BN) and 5.3% for eating disorders not otherwise specified (EDNOS). The relationship between EDs and AIS was further tested through a second analysis. Severity of the rachides pathology was correlated with the presence of AN. Our study supports the hypothesis of a comorbidity between AIS and EDs: Some possible clinical explanations for this association are discussed.     

A transcultural outcome study of adolescent eating disorders

OBJECTIVE: The aim of the study was to assess the treatment and outcome of adolescent eating disorders in an international study including Western and Eastern European clinical and research centres. METHOD: A total of 138 patients with adolescent onset of an eating disorder (primarily anorexia nervosa) were followed-up after a mean interval of 5 years after first admission. RESULTS: On average, the patients had spent 25% of the total follow-up period in either in-patient or out-patient treatment. Half of them required a second hospitalization and a quarter required a third hospitalization for the eating disorder. At follow-up, 68% of the total sample did not have an eating disorder. The prediction of outcome revealed different patterns of risk variables depending on the type of criterion. CONCLUSION: The outcome of adolescent eating disorders is relatively similar across cultures, and better than in patients with later onset of the disorder.     

The prevalence and severity of insomnia in university students and their associations with migraine,tension-type headache,anxiety and depression disorders: a cross-sectional study

BackgroundThere is possibly an association between migraine, tension-type headache, anxiety, depression and insomnia. These conditions are prevalent among university students. Our primary objective was to verify whether students with primary headaches (migraine and tension-type headache) have a higher prevalence of insomnia. Our secondary objective was to assess whether the impact of headaches was associated with greater severity of insomnia.MethodsCross-sectional study. 440 students out of 3030 were randomly selected. A semi-structured questionnaire containing information about the characteristics of the headaches, including their frequencies in the last 3 months; the Headache Impact Test (HIT-6); the Hospital Anxiety Depression Scale; and the Insomnia Severity Index were used.Results420 students (95.5%) agreed to participate; 51.4% men; median age of 21 (19, 23); 95 (22.6%) had insomnia; 265 (63.1%), migraine; 152 (36.2%), tension-type headache; 201 (47.9%) suffered from anxiety and 108 (25.7%), from depression. The severe impact of headache (HIT-6>55 points; OR = 3.9; p = 0.003) and anxiety (OR = 3.6; p = 0.003) were associated with insomnia (logistic regression). The severity of insomnia was positively and significantly correlated with the impact (HIT-6 score), with frequency of headache, and with having anxiety (multiple linear regression).ConclusionsThe diagnoses of migraine and tension-type headache are not associated with the presence of insomnia. The severity of insomnia is associated with the impact and the frequency of the headaches.
