Sleep profile in anorexia and bulimia nervosa female patients

ObjectiveSleep wake cycle and eating patterns undergo major changes throughout life and have been proved to be very correlated. Eating disorder prevalence is increasing and sleep problems are very common among them. The current study is concerned with investigating the sleep pattern in anorexia and bulimia female patients using both subjective and objective assessment tools.MethodsA cross sectional study of sleep patterns using structured sleep disorder questionnaire and full night polysomnography in 23 female patients with bulimia and anorexia, patients aged 18–45 years not on any treatment for a month at least, compared to a sex and age matched control group (20 participants), all cases were collected from the Institute of Psychiatry, Ain Shams University over 18 months interval.ResultsSignificant affection of most domains of sleep measured by subjective and objective assessment tools in patients compared with the control group.DiscussionSleep is equally affected in bulimia and anorexia patients, confirming that sleep and eating disorders are highly correlated. Sleep may be a clinical marker in eating disorders.     

Prevalence,incidence, and natural course of anorexia and bulimia nervosa among adolescents and young adults

We aimed to assess the prevalence, incidence, age-of-onset and diagnostic stability of threshold and subthreshold anorexia nervosa (AN) and bulimia nervosa (BN) in the community. Data come from a prospective-longitudinal community study of 3021 subjects aged 14–24 at baseline, who were followed up at three assessment waves over 10 years. Eating disorder (ED) symptomatology was assessed with the DSM-IV/M-CIDI at each wave. Diagnostic stability was defined as the proportion of individuals still affected with at least symptomatic eating disorders (EDs) at follow-ups. Baseline lifetime prevalence for any threshold ED were 2.9 % among females and 0.1 % among males. For any subthreshold ED lifetime prevalence were 2.2 % for females and 0.7 % for males. Symptomatic expressions of EDs (including core symptoms of the respective disorder) were most common with a lifetime prevalence of 11.5 % among females and 1.8 % among males. Symptomatic AN showed the earliest onset with a considerable proportion of cases emerging in childhood. 47 % of initial threshold AN cases and 42 % of initial threshold BN cases showed at least symptomatic expressions of any ED at any follow-up assessment. Stability for subthreshold EDs and symptomatic expressions was 14–36 %. While threshold EDs are rare, ED symptomatology is common particularly in female adolescents and young women. Especially threshold EDs are associated with a substantial risk for stability. A considerable degree of symptom fluctuation is characteristic especially for subthreshold EDs.     

The intellectual functioning of adolescents with anorexia nervosa and bulimia nervosa

The aim of this study was to investigate the intellectual functioning of a large group of eating disordered adolescents in order to test two hypotheses, viz, that the intellectual functioning of eating disordered adolescents conforms to the normal distribution, and that eating disordered adolescents do not perform better in verbal abilities than in nonverbal abilities. Standard intelligence tests were applied to 190 consecutive out- and inpatients with eating disorder diagnoses. The results were compared with those of a group of patients with other disorders, similar in age, sex, SES, and year of admission. The IQ of the eating disordered patients was significantly higher than that of patients in the comparison group. Patients in the comparison group and bulimic patients, but not anorexic patients, showed better nonverbal than verbal intellectual performance.     

Prevalence of anorexia nervosa and bulimia among young diabetic women

To assess the prevalence of anorexia nervosa and bulimia among young diabetic women, a questionnaire was sent to 264 young women with insulin-dependent diabetes mellitus in two clinical settings. Among the women who responded (30%), none reported a history of anorexia nervosa, but 28 (35%) reported a history of bulimia. These results suggest that bulimia represents a common problem among young women with diabetes.     

Predictors of treatment utilization among women with anorexia and bulimia nervosa.

OBJECTIVE: The authors sought predictors of treatment utilization among women with eating disorders. METHOD: Women diagnosed with either anorexia or bulimia nervosa (N=246) completed prospective evaluations of eating disorder status, comorbid disorders, global assessment of functioning, and treatment utilization. RESULTS: Women with anorexia nervosa received significantly more inpatient treatment than did women with bulimia nervosa. Predictors of treatment utilization included lower global assessment of functioning scores and presence of personality disorders. CONCLUSIONS: Women with more severe pathology have higher treatment utilization rates. This pattern may explain the seeming lack of treatment efficacy for eating disorders outside of randomized controlled studies.     

Brief report: Binge drinking among high-risk male and female adolescents in Israel

A major factor attributed to the problem and consequences of underage alcohol use is binge drinking. The objective of this study was to examine binge drinking and other alcohol-related problem behaviour among high-risk male and female adolescents who were from alternative schools and programs because of learning and/or behaviour problems. Self-report data were collected from a purposive sample of 917 adolescents in Israel who ranged from 12 to 18 years. Binge drinking during the last 30 days prior to the survey was reported by 33% of males and 23% of females (p<.001). Results of other alcohol-related behaviour showed gender status not related to being in a car when the driver had been drinking (12%) or having driven a car or motorcycle after drinking (5%). Multiple regression analysis showed binge drinking related to what a youth does with time; a decline in relations with family members; selling drugs; and, having been in a serious fight during the last 12 months. Country of origin, i.e. born in Israel or the Former Soviet Union, was not found linked to binge drinking. Further research of binge drinking and alcohol-related problem behaviour among high-risk youth is important so that it can be applied to immediate and longstanding prevention efforts.     

Prevalence and age-of-onset distributions of DSM IV mental disorders and their severity among school going Omani adolescents and youths: WMH-CIDI findings

Background  

There is a dearth of studies exploring the magnitude of mental disorders amongst adolescents and youths in the Arab world. To our knowledge, this phase 2 survey in Oman is the first nationally representative school-based study to determine the prevalence of DSM-IV mental disorders (lifetime and over the preceding 12 months), their age-of-onset distributions and determine their severity over the past 12 months using the World Mental Health-Composite International Diagnostic Interview, the WMH-CIDI, used for international comparison.     

Bone mineral density in male adolescents with anorexia nervosa

OBJECTIVES: To determine the percentage of male adolescent patients with abnormal bone mineral density (BMD), to identify the variables related to BMD loss, and to study BMD change after follow-up. METHOD: Dual-energy-x-ray absorptiometry tests at the lumbar spine (L2-L4) and the femoral neck were administered in 20 male adolescents with anorexia nervosa (treated from 1997 until 2000 at the Department of Child and Adolescent Psychiatry and Psychology of the Hospital Clinic Universitari in Barcelona). Examinations were repeated in 15 patients after a follow-up of 6 to 24 months. RESULTS: Thirty-five percent of patients had osteopenia at the lumbar spine and femoral neck. The following variables were related to osteopenia: >12 months' duration of anorexia (p = .003), <3 hours/week of physical activity (p = .009), and calcium intake <600 mg/day (p = .015). In a stepwise logistic regression analysis to predict spinal BMD with the three variables mentioned above, only months of duration entered in the equation (beta = 3.5, SE = 1.3, p = .008) and correctly classified 85% of patients. At the follow-up, patients with only partial weight recovery had a BMD loss of 3.2% at lumbar spine and 6.4% at femoral neck, whereas patients with total weight recovery had an increase of 7.8% at lumbar spine and 6.7% at femoral neck. CONCLUSIONS: The risk of osteopenia in male adolescents with anorexia of more than 12 months' duration is high. In patients with total weight recovery, BMD increase is higher than normal.     

Hypothalamic-pituitary-gonadal function in anorexia nervosa and bulimia

Patients with anorexia nervosa (AN) exhibit neuroendocrine abnormalities that may result solely from emaciation or may reflect defective endocrine mechanisms which are intrinsic to disordered eating even in the absence of starvation. To distinguish these possibilities, we have studied indices of hypothalamic-pituitary-gonadal (HPG) function in 9 patients with AN, 12 normal weight patients with bulimia and recent or current oligomenorrhea, and 8 normal weight controls. Measurement of 24-hour luteinizing hormone (LH) secretion with 30-min sampling revealed significantly fewer LH secretory spikes and a trend toward lower mean 24-hour LH levels in both bulimic and anorectic patients than in controls. Stimulation with gonadotropin releasing hormone produced elevated LH responses in the bulimic group and blunted LH responses in the anorectic group. Stimulation with estradiol revealed diminished LH augmentative responses and a trend toward diminished follicle stimulating hormone augmentative responses among bulimic as well as AN patients compared to controls. In each instance, the bulimic group tended to show within-group heterogeneity, with some individuals falling within the AN range. These findings suggest that HPG axis abnormalities in eating disordered patients cannot entirely be attributed to emaciation and that factors other than subnormal weight contribute to disturbed hypothalamic-pituitary functioning in these patients.     

Self-forgiveness in anorexia nervosa and bulimia nervosa

This study investigated whether low levels of self-forgiveness were associated with eating disorder symptomatology. Participating women (N = 51) had diagnoses of anorexia nervosa, bulimia nervosa, or no eating disorder diagnosis. They completed 3 measures of self-forgiveness. Women with eating disorders had lower levels of self-forgiveness compared with control participants. Results suggest that incorporating self-forgiveness interventions into current eating disorder treatments should be evaluated in future research as they might enhance clinical outcomes.     

Stealing in anorexia nervosa and bulimia nervosa

Only recently stealing behaviour has been noticed as a symptom of anorexia nervosa and bulimia nervosa. Reviewing our sample of 63 patients we discuss the incidence and motivation of kleptomania. In 24% of our patients stealing behaviour was reported which is a definitely high rate compared to literature. Among the intentions for stealing behaviour we found: Stealing as conversion of revenge, self-assertiveness compensation of binge-eating or stealing as achievement. The differential motivation of stealing should be considered in legal consequences.     

EEG-monitored sleep in anorexia nervosa and bulimia

We compared the EEG-monitored sleep of 8 women with anorexia nervosa and 16 normal weight women with bulimia to that of 14 normal women. The patients with anorexia nervosa spent less time asleep and spent less of their sleep time in Stage 1. The sleep of the normal weight patients with bulimia was remarkably similar to that of the controls. These data suggest that most patients with anorexia nervosa and bulimia do not exhibit the type of sleep disturbances characteristic of patients with major depressive illness.     

Pharmacotherapy for anorexia nervosa and bulimia nervosa

Psychotherapy is the treatment of choice for both anorexia nervosa and for bulimia nervosa. However, many patients are also treated by pharmaceutical drugs. For the clinician it is difficult to choose pharmacotherapy, because the drugs may not be licensed, because of pharmacodynamic problems due to underweight or purging behaviour, or because of comorbidity. The present review summarises the current knowledge on pharmacotherapy for anorexia nervosa and bulimia nervosa considering the available guidelines. In general, the knowledge based on studies is insufficient for anorexia nervosa. Up to now, there is no proof of efficacy for any antidepressant or atypical antipsychotic with respect to weight gain; atypical antipsychotics may be helpful for ruminating or excessive motor hyperactivity. For bulimia nervosa antidepressants are the pharmacotherapy of first choice. Long-term effects, however, are still unknown.
