Gambling-related suicide in Victoria, Australia: a population-based cross-sectional study

Area of Science:

• Public Health
• Epidemiology
• Mental Health Research

Background:

• Gambling is linked to severe health issues, including suicide.
• Current public health systems inadequately record gambling's role in suicide deaths.
• Understanding gambling-related suicides (GRS) is crucial for public health interventions.

Purpose of the Study:

• To determine the incidence and characteristics of gambling-related suicides (GRS) in Victoria.
• To analyze the demographic and social factors associated with GRS.
• To inform public health strategies for preventing gambling-related harm and suicide.

Main Methods:

• A population-based, cross-sectional study of suicide deaths reported to the Coroners Court of Victoria (2009-2016).
• Identification of direct GRS and GRS involving 'affected others'.
• Statistical analysis of incidence rates and demographic characteristics.

Main Results:

• A total of 4,788 suicide deaths occurred in Victoria from 2009-2016.
• 184 direct GRS and 17 GRS by 'affected others' were identified, comprising 4.2% of all suicides.
• GRS were more prevalent in males (83%), occurred in disadvantaged populations, and were often known to family/friends rather than clinicians.

Conclusions:

• The study likely underestimates the true scale of GRS due to underreporting and hidden gambling behavior.
• Public health measures for prevention, screening, support, and treatment of gambling harm are urgently needed.
• Addressing gambling-related harm can significantly reduce suicidality and suicide rates globally.
