[Separation anxiety disorder and eating disorders]

Area of Science:

• Child and Adolescent Psychiatry
• Clinical Psychology
• Eating Disorder Research

Background:

• Separation anxiety disorder (SAD) is a prevalent childhood anxiety disorder.
• The long-term outcomes of childhood SAD, particularly regarding other psychiatric conditions, remain incompletely understood.
• High comorbidity rates exist between eating disorders and other mental health conditions.

Purpose of the Study:

• To investigate the prevalence of childhood separation anxiety disorder (SAD) in young patients diagnosed with anorexia nervosa (AN) or bulimia nervosa (BN).
• To examine the association between a history of childhood SAD and the presence of comorbid anxiety and depressive disorders in individuals with eating disorders.
• To explore the implications of childhood SAD for the development and treatment of eating disorders.

Main Methods:

• A follow-back study was conducted on 81 young patients diagnosed with AN or BN according to DSM III-R criteria.
• Psychiatric histories (current and lifetime) were assessed using structured interviews, including the Schedule for Affective Disorders and Schizophrenia-Lifetime Version (SADS-LA) and the Structured Clinical Interview for DSM-III-R-Revised (SCID).
• The psychopathological profile was evaluated using the Symptom Checklist-90 (SCL-90).

Main Results:

• Approximately 20% of young patients with AN and BN reported a history of childhood separation anxiety disorder (SAD).
• Patients with a history of childhood SAD exhibited significantly higher rates of associated anxiety and depressive disorders compared to those without.
• These findings indicate a specific link between childhood SAD and the development of eating disorders.

Conclusions:

• Childhood separation anxiety disorder (SAD) is associated with an increased risk for developing anorexia nervosa (AN) and bulimia nervosa (BN).
• Individuals with a history of childhood SAD and eating disorders are more prone to comorbid anxiety and depressive disorders.
• Epidemiological research on childhood SAD is crucial for informing prevention and treatment strategies for eating disorders.
