Assessment & Treatment of Children and Adolescents with Eating Disorders

1. Introduction

Eating disorders (EDs) in youth are serious mentalhealth conditions that affect physical growth, emotional development, and academic performance. Early identification and evidencebased treatment improve outcomes and reduce longterm morbidity. This page outlines a concise, evidenceinformed approach for clinicians, school personnel, and families.

2. Core Concepts

2.1 Definition of Eating Disorders in Youth

The DSM5TR recognises several primary ED diagnoses applicable to children and adolescents:

• Anorexia Nervosa (AN) restriction of energy intake, intense fear of gaining weight, and disturbance in selfperceived weight or shape.
• Bulimia Nervosa (BN) recurrent episodes of binge eating followed by inappropriate compensatory behaviours (vomiting, laxatives, excessive exercise).
• BingeEating Disorder (BED) recurrent binge eating without regular compensatory actions.
• Avoidant/Restrictive Food Intake Disorder (ARFID) restrictive eating not driven by bodyimage concerns, often due to sensory sensitivity, fear of aversive consequences, or lack of interest in eating.

2.2 Developmental Considerations

Younger children may express distress through somatic complaints, while adolescents often have clearer concerns about weight and shape. Pubertal status, family dynamics, and peer influence must be woven into the assessment.

3. Assessment Framework

A systematic, multidisciplinary assessment is essential. The process can be divided into three stages: screening, comprehensive evaluation, and ongoing monitoring.

3.1 Initial Screening

Screening tools are brief, easy to administer, and can be used in primarycare or school settings.

• SCOFFA adapted for adolescents (5item questionnaire).
• Eating Disorder ExaminationQuestionnaire (EDEQ) short version suitable for ages 1217.
• ARFID Screen (ARFIDQ) focuses on restrictive eating patterns unrelated to body image.

Scores above established cutoffs should trigger a full evaluation.

3.2 Comprehensive Evaluation

When screening is positive, a multidisciplinary team (MDT) should conduct a detailed assessment that includes:

Medical Examination

• Vital signs, orthostatic vitals, heart rate, blood pressure.
• Weight, height, BMI percentile, and growthchart trajectory.
• Laboratory tests: electrolytes, CBC, thyroid function, liver enzymes, bonedensity (if indicated).
• Cardiac workup (ECG) for bradycardia or QT prolongation.

Psychological Assessment

• Structured interview e.g., Eating Disorder Examination (EDE) or the Child version (EDEC).
• Comorbidities: depression (CDI2), anxiety (RCADS), OCD, ADHD, autism spectrum traits.
• Motivation to change assessed with the Motivation for Change Scale (MFCS).

Family and Social History

• Family history of EDs, mood disorders, substance use.
• Parenting style, family meals, and communication patterns.
• School performance, peer relationships, bullying experiences.

3.3 Risk Stratification

Based on medical stability and psychiatric risk, patients are grouped into:

• Medical Stability normal vitals, no electrolyte imbalance, able to maintain safe oral intake.
• Medical Instability bradycardia < 50bpm, hypotension, severe dehydration, or rapid weight loss >10%/month.
• Psychiatric Risk suicidality, severe depression, selfharm, or inability to engage in treatment.

Instability warrants inpatient or intensive residential care.

4. EvidenceBased Treatment Approaches

4.1 FamilyBased Treatment (FBT)

FBT, also known as the Maudsley model, is the firstline intervention for adolescents with AN and atypical AN. Core phases:

1. Phase I Weight Restoration: Parents take charge of nutrition, monitoring meals and calories.
2. Phase II Return of Control: Gradual handover of eating decisions back to the adolescent.
3. Phase III Adolescent Issues: Focus on developmental tasks, autonomy, and relapse prevention.

Outcomes: 6070% of families achieve medically safe weight within 6months, with lasting remission rates >50% at twoyear followup.

4.2 CognitiveBehavioral Therapy (CBTE)

Adapted CBT for eating disorders (CBTE) is the treatment of choice for BN, BED, and ARFID in older children and adolescents.

• Focus on normalising eating patterns, challenging distorted thoughts, and developing coping skills.
• Standard duration: 1620 weekly sessions.
• Evidence: remission of binge-purge cycles in >60% of adolescents with BN.

4.3 Interpersonal Psychotherapy (IPTA)

IPTA targets interpersonal triggers of disordered eating, particularly useful for adolescent girls with BN or subthreshold symptoms. Shortterm (1216 sessions) and effective in reducing binge eating.

4.4 Treatment of ARFID

ARFID requires a blend of medical, nutritional, and behavioural strategies:

• Occupational therapy for sensory issues.
• Gradual exposure and systematic desensitisation to feared foods.
• Parentled mealtime structure and reinforcement.

4.5 Pharmacological Adjuncts

Medication is not firstline but can support therapy in specific cases:

• Fluoxetine FDAapproved for BN in adolescents 12years; helps reduce binge-purge frequency.
• Olanzapine lowdose may aid weight gain and anxiolysis in AN.
• SSRIs for comorbid depression/anxiety, but only after weight restoration (to ensure efficacy).

4.6 Nutritional Rehabilitation

Registered dietitians (RDs) develop individualized refeeding plans:

• Caloric needs: start at 3040kcal/kg/day for AN, increase by 200300kcal every 23days.
• Balanced macronutrients, micronutrient supplementation (iron, vitaminD, calcium).
• Meal planning education for families and adolescents.

4.7 Inpatient & Residential Care

Reserved for medically unstable patients or those unable to engage in outpatient treatment. Key components:

• 24hour medical monitoring.
• Structured meals with supervised eating.
• Integrated psychotherapy (FBT, CBTE) and family therapy.

5. Monitoring & Relapse Prevention

Continuous evaluation of weight, vital signs, and psychological status is vital.

• Weight checks: weekly during active treatment, then biweekly to monthly.
• Psychometric scales: EDEQ or SCOFFA every 34weeks.
• Family meetings: review progress, address conflict, reinforce coping strategies.

Relapse triggers often include major life stressors, perfectionism, or unsupervised eating. A written relapseprevention plan should be part of discharge documentation.

6. Special Populations

6.1 Young Children (12years)

Assessment relies heavily on parental report and growth curves. Earlyintervention programs combine behavioural feeding therapy with parental coaching.

6.2 LGBTQ+ Youth

Higher prevalence of EDs; treatment must be affirmative, address gender dysphoria if present, and involve providers knowledgeable about minority stress.

6.3 Cultural Considerations

Bodyimage ideals vary across cultures. Clinicians should use culturally adapted screening tools and respect family food traditions while promoting nutrition.
