EATING DISORDERS IN CHILDREN AND ADOLESCENTS —Eric Rickin, MD, Assistant Professor of Psychiatry, Western Psychiatric Institute, University of Pittsburgh Medical Center, Pittsburgh, PA
Introduction: little literature on eating disorders in adolescents; information often must be extrapolated from data on adults
Definitions: criteria from Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)
Anorexia nervosa: refusal to maintain minimal (85%) body weight for age and height; failure to maintain weight due to weight loss or failure to make expected weight gain during growth period (in Europe, ideal body weight calculated from body mass index [BMI], but in United States, tables from variety of sources used); intense fear of gaining weight or becoming fat, even though underweight; disturbance in experience of weight or body shape, undue influence of body weight or shape on self-evaluation, or denial or seriousness of low weight; amenorrhea does not occur in all women and will be dropped as criterion in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-V; speaker recommends disregarding it under DSM-IV); types—restricting type (food intake restricted, with no binge eating or purging behavior); binge eating/purging type (normal amount of food eaten, followed by binge eating or purging behavior)
Bulimia nervosa: eating large amount of food in discrete period (<2 hr) that is more than most people would eat, or loss of control over eating during episode; recurrent inappropriate compensatory behavior (eg, self-induced vomiting, misuse of laxatives, diuretics, enemas, or other medications, fasting, excessive exercise) to prevent weight gain; binge eating and compensatory behaviors occur, on average, at least twice weekly for 3 mo; self-evaluation unduly influenced by body shape or weight; does not occur exclusively during episodes of anorexia nervosa; types include purging type (regular engagement in self-induced vomiting or misuse of laxatives, diuretics, or enemas) and nonpurging type (use of other inappropriate compensatory behaviors such as fasting or exercise); bulimia differentiated from purging-type anorexia nervosa by extremely low weight in latter
Eating disorder not otherwise specified (NOS): any eating disorder that does not fully meet criteria for anorexia or bulimia nervosa; most common diagnosis among those who seek treatment; spectrum includes behaviors of anorexia and bulimia nervosa, and binge-eating disorder (defined as binge eating without compensatory behaviors of bulimia nervosa; patients often overweight or obese, have distress from binge eating; bingeing at least 2 days/ wk for 6 mo; will be separate diagnosis in DSM-V)
Epidemiology and outcomes: anorexia nervosa—preva-lence 0.3% to 1%; female-to-male ration 10:1; peak age at onset, 15 to 19 yr; tends to be chronic; 50% to 60% recover, 30% improve, and 7% to 15% experience chronic course; mortality 5.6% per decade in patients with chronic course (highest of any psychiatric disorder); bulimia nervosa—prevalence 1% to 3%; female-to-male ratio 10:1; peak age at onset, late teens to early 20s; fluctuating short-term course, with cycles of remission and exacerbation; high relapse rates; no increased risk for death
Etiology: unknown but multifactorial; biologic—family and twin genetic studies suggest strong genetic component; genetic-linkage and association studies implicate several susceptibility loci; neurotransmitter studies indicate dysregulation in serotonin, dopamine, and/or norepinephrine; psychologic—low self-esteem; perfectionism; neuroticism, difficulties in self-soothing or affect regulation; people with anorexia nervosa tend to be obsessive, rigid, and harm-avoidant; those with bulimia nervosa tend to be impulsive and have difficulties with self-regulation; results of Minnesota Starvation Experiment showed that starvation itself causes many behaviors seen in anorexia nervosa; family and sociocultural—high levels of family conflict; parental preoccupation with weight and shape; unrealistically high expectations for achievement; sociocultural overvaluation of thin-body ideal
Medical issues associated with starvation: cardiovascular—hypotension and orthostasis; sinus bradycardia; QTc and T-wave changes on electrocardiography (ECG); edema (etiology unknown; worst in patients with purging-type anorexia nervosa during refeeding); gastrointestinal (GI)—constipation; decreased gastric motility; nutritional hepatitis (rare); hypercholesterolemia; endocrine—decreased basal metabolic rate; disturbances in growth hormone, cortisol, and thyroid function tests; hypoglycemia; decreased libido; possible amenorrhea; hematologic—bone marrow hypoplasia; leukopenia with relative lymphocytosis; anemia; nervous system— seizures in 5%; depression; sleep disturbance; poor concentration; apathy; weakness; paresthesias; hypothermia; hyperacuity to noise and light; structural brain changes on magnetic resonance imaging (MRI)
Medical issues associated with bingeing and purging: GI-related—hyperamylasemia and parotid gland enlargement; pancreatitis (check lipase, not amylase); esophageal reflux; gastric dilation/perforation; upper GI bleeding; gastroduodenal ulcers; erosion of tooth enamel and periodontitis; cardiovascular—arrhythmias due to hypokalemia; cardiomyopathy (due to use of emetics); biochemical disturbances—decreased levels of potassium, sodium, phosphorus (especially during refeeding), magnesium, and calcium; metabolic alkalosis (due to vomiting); metabolic acidosis (due to use of laxatives)
Management: patient must have primary care physician for managing medical issues; patients often need frequent laboratory tests and ECGs; approach must be multifocal (medical management, psychotherapy, psychopharmacology) and multidisciplinary (psychiatrist, therapist, dietitian, primary care physician); levels of care available include acute hospital, day hospital, intensive outpatient, outpatient, and residential; consider residential (ie, hospitalization) if weight <75% of ideal body weight, to stabilize and treat physical complications, to interrupt binge-purge cycle, vomiting, or laxative abuse that poses medical risks, and/or if patient has comorbid psychiatric disorder, especially depression and/or suicidality
Treatment of anorexia nervosa: restoration of weight cornerstone of treatment; psychotherapy includes family therapy for children and adolescent patients, and cognitive behavioral therapy for adults; Maudsley/Lock- LaGrange program trains family members to be primary therapists in home; phase 1 devoted to refeeding, lasts 3 to 5 mo; phase 2 comprises negotiations for new relationship patterns; phase 3 comprises dealing with adolescent issues and termination; pharmacotherapy—not primary treatment but may be useful for comorbidities; antidepressants not effective in patients with <85% of ideal body weight and do not help in maintenance treatment; atypical antipsychotics may help decrease anxiety and body-image distortions; benzodiazepines may help decrease anxiety in short term
Treatment for bulimia nervosa: selective serotonin reuptake inhibitors (SSRIs) moderately helpful in decreasing bingeing and purging; studies just beginning with topiramate (use cautiously); avoid bupropion, due to increased risk for seizures; cognitive behavioral therapy
ATYPICAL ANTIPSYCHOTICS AND METABOLIC SYNDROME IN ADOLESCENTS AND CHILDREN — Bruce Meltzer, MD, Assistant Professor of Pediatrics and Child Psychiatry, University of Massachusetts Medical School, Worcester
Introduction: most data on metabolic syndrome from studies in adults; difficult to assess cardiovascular risk and medication effects in children, whose height, weight, and BMI constantly change; guidelines include the Adult Treatment Protocol (ATP) and guidelines of World Health Organization (WHO); WHO guidelines stress prevention of insulin resistance, prediabetes, and diabetes (“which [are] actually not uncommon among kids”); insulin resistance and prediabetes best predictors of who develops metabolic syndrome
Obesity: ideal BMI, 19 to 21; mortality increases as BMI >21 or <19; known since antiquity that death more common among overweight people than among lean; recent studies show obesity and death more common among severely and persistently mentally ill (although some statistics not corrected for suicide); abnormal glucose tolerance in young children associated with low rates of diabetes, but by early adolescence, glucose intolerance progresses to prediabetes and to frank diabetes
Risk factors for metabolic syndrome: in adults, prediabetes, obesity, and elevated blood pressure (BP); early evidence indicates these risk factors also present in children; National Health and Nutrition Evaluation Study (NHANES) shows that BP starts to become elevated in people who are as little as 5% overweight; autopsy findings on youth killed in accidents show fatty streaks and raised lesions (predictors of coronary artery disease) already present in 15- to 24-year-olds
Population-based risks: 15% of children in United States overweight; obesity rates for individuals 2 to 19 yr of age doubled in last 3 decades, and tripled for children 6 to 11 yr of age; takes 10 yr from onset of insulin resistance to appearance of first symptoms of diabetes; however, the heavier the individual, the faster the progression; poverty, more than any other factor, associated with obesity; Mississippi, Alabama, and West Virginia were states with highest rates of obesity in 2002; in 1994, Alabama and Louisiana had obesity rates >6%; unclear why rates of obesity and death higher in people with severe and persistent mental illness (may be sedentary lifestyle, may be that genetic factors that predispose to mental illness also predispose to obesity)
Second-generation (atypical) antipsychotic medications: associated with weight gain in many cases; as of 2003, all antipsychotic agents must carry warning about risk of developing hyperglycemia and diabetes; as number of prescriptions for atypical antipsychotics rose, number of prescriptions for typical antipsychotics remained stable; speaker suggests this is because primary care providers more comfortable prescribing atypical antipsychotics; “boys are vastly over-represented” in prevalence of use of atypical antipsychotics from birth to 19 yr of age; data supporting safety and efficacy of atypical antipsychotics in children and adolescents very limited; weight gain single greatest concern
Ziprasidone: study shows children and adolescents respond differently to ziprasidone than do adults; young people gained weight on ziprasidone, compared to molindone, and to adolescents (“gaining weight is awful”); another study showed that patients who gained weight improved psychiatrically, indicating that those patients were compliant with medication regimen
Schizophrenia and diabetes: association known since 1919 (before discovery of antipsychotic medications); at that time, rates of diabetes in patients with schizophrenia 2 to 4 times greater than in general population; quadrupled with introduction of chlorpromazine (Thorazine)
Not everyone gains weight: no method to predict which patients will gain weight on atypical antipsychotics; dose-response relationship not seen in clinical use; weight of patients on olanzapine must be monitored carefully; few studies available on weight gain and aripiprazole in adolescents (tends to be weight-neutral in adults)
Monitoring: growth charts available from Centers for Disease Control and Prevention (www.cdc.gov); Hispanic and Asian American children tend to follow different course from white children; consensus protocol for monitoring children and adolescents derived from adult literature; suggests examining family history, and monitoring weight, waist circumference, BP, fasting blood glucose, and fasting lipid profile; speaker able to incorporate all monitoring and screening on 1-page form in his own practice
Diet recommendations: in speaker’s program, children told to pay attention to “4 Ss,” ie, seconds, sweets, snacks, and soda (not just regular sodas; some evidence indicates that diet sodas, by unclear mechanism, drive appetite); recommendations for cholesterol screenings—positive family history (proband with cardiovascular event before 50 yr of age in males, age 60 yr in females); if total cholesterol <240 mg/dL, speaker obtains nutrition consultation and focuses on psychoeducation and encourages physical activity; if total cholesterol >240 mg/dL, high-density lipoprotein (HDL) cholesterol >160 mg/dL, or triglycerides >300 mg/dL, consider medication; some types of oral contraceptives can increase low-density lipoprotein (LDL) cholesterol; dietary interventions—reduce calories and saturated fats; increase whole grains, fruits, and vegetables; eat fruits for snacks; speaker’s program encourages children to get 2 hr/day of exercise (“we write prescriptions for exercise”); dietary maxims—portion control; impulse control; appropriate food- group selection; healthy exercise
