Which Comes First? An Examination of Associations and Shared Risk Factors for Eating Disorders and Suicidality

Curr Psychiatry Rep. 2018 Aug 9;20(9):77. doi: 10.1007/s11920-018-0931-x.

Abstract

Purpose of review: This narrative review evaluates recent literature on the associations between eating disorders and suicidality and discusses potential shared mechanisms that may account for these relationships. Additionally, the review highlights shortcomings with the literature to date and suggests avenues for future research.

Recent findings: Individuals with anorexia nervosa, bulimia nervosa, and binge eating disorder experience elevated rates of suicidality compared to the general population. Suicide risk is higher when eating disorders occur with other psychological conditions. Additionally, genetic factors, emotion dysregulation, trauma, stressful life events, and lack of body regard may have roles in the development of both eating disorders and suicidality. Much of the risk for suicidality in eating disorders appears to be driven by comorbid psychopathology and genetic factors. However, the lack of longitudinal research makes it difficult to draw conclusions about the directionality or temporality of these relations; thus, novel methods are needed.

Keywords: Binge eating disorders; Bulimia nervosa; Eating disorders; anorexia nervosa; Suicidal ideation; suicide attempt; suicide; Suicidality.
