Why are people with eating disorders at higher risk of suicide?

Funding Period: 2023-2026

Eating disorders have one of the highest mortality rates in comparison to other psychiatric illnesses, and 1 in 5 individuals with anorexia nervosa who die, do so due to suicide. Furthermore, people with an eating disorder are more likely to engage in self-harm and experience suicidal ideation. These are distressing for themselves and their families, and are strong risk factors for suicide.

The project

This research project combines data science and perspectives from people with lived experience in order to map out why people with eating disorders are at a higher risk of suicide.

The project aims to build and test a theoretical model that describes the mechanisms between different eating disorders and thoughts of suicide and self-harm.

The process

There is currently no theoretical framework that explains why people with eating disorders are at a higher risk of suicide or thoughts of self-harm. This project will:

  1. Gather qualitative data from people with lived and living experience of anorexia, bulimia and binge eating disorders, as well as clinicians. This will be done through interviews, focus groups and other methods to identify core themes about the link between eating disorders and self-harm/suicide. Together with people with lived experience and clinicians, researchers will co-create a new theoretical model.
  2. Once the theoretical model has been formed, it will be tested using secondary data analyses from various sources including the NIHR BioResource and Eating Disorders Genetic Initiative.

The potential

This project will help us to better understand why people with eating disorders are at a higher risk of suicide, therefore leading to more effective ways of preventing it from happening.

By increasing our understanding of the mechanisms between eating disorders, suicidal ideation and thoughts about self-harm, we can identify methods for more targeted interventions, improve overall clinical care and provide better support for patients and their families.
