Summary
Binge eating disorder (BED) significantly increases suicidal behaviors and ideation. Clinical attention should focus on psychopathological factors to prevent and treat suicidality in BED patients.
Area of Science:
- Psychiatry
- Clinical Psychology
- Eating Disorders
Background:
- Binge Eating Disorder (BED) is a recently recognized eating disorder.
- Understanding the link between BED and suicidality is crucial for patient care.
Purpose of the Study:
- To systematically review and synthesize qualitative data on the relationship between BED and suicidality.
- To identify predictive factors and at-risk populations for suicidality in BED.
Main Methods:
- Systematic literature search across multiple databases (PubMed, Scopus, etc.) following PRISMA guidelines.
- Inclusion of 17 research reports analyzing the association between BED and suicidal behaviors/ideation.
- Keywords: "binge eating disorder" AND "suicid*".
Main Results:
- BED is significantly associated with increased suicidal behaviors and suicidal ideation (SI).
- BED presence and severity are predictive of suicidality, especially with mood disorders and specific psychological features.
- High BMI did not consistently correlate with suicidality; BED with other psychiatric disorders or in adolescents poses higher suicide risk.
Conclusions:
- Dysfunctional eating behaviors and associated psychopathological factors in BED necessitate clinical attention for SI and suicidal behavior.
- Identifying patients and subgroups at higher risk is essential for effective prevention and treatment of suicidality in BED.
