Suicidality in body dysmorphic disorder (BDD): A systematic review with meta-analysis

Area of Science:

• Psychiatry
• Mental Health Research
• Clinical Psychology

Background:

• Body Dysmorphic Disorder (BDD) is associated with high rates of suicidal ideation and behaviors.
• A systematic review and meta-analysis was needed to quantify the relationship between BDD and suicidality.
• Existing research highlights the severity of suicidality in BDD patients.

Purpose of the Study:

• To systematically review and meta-analyze the association between Body Dysmorphic Disorder (BDD) and suicidality.
• To explore potential mechanisms underlying suicidality in individuals with BDD.
• To provide a quantitative estimate of the relationship between BDD and various forms of suicidality.

Main Methods:

• Systematic review and meta-analysis of seventeen studies.
• Searches conducted across five major bibliographic databases (Medline, PsychINFO, Embase, Web of Science, CINAHL).
• Random effects models used for meta-analyses to address data heterogeneity.

Main Results:

• A significant positive association was found between BDD and suicidality (OR=3.63).
• BDD was linked to increased odds of suicide attempts (OR=3.30) and suicidal ideation (OR=2.57).
• Evidence for suicide deaths in BDD was limited; BDD-specific factors and comorbid Axis I disorders may exacerbate suicidality.

Conclusions:

• Body Dysmorphic Disorder (BDD) is significantly associated with increased risk of suicidality.
• BDD-specific factors and comorbid conditions appear to worsen suicidality.
• The findings should be interpreted with caution due to the limited number and methodological quality of included studies.
