Gambling Disorder and Increased Psychiatric Comorbidity: A Finnish Register-Based Study.

Area of Science:

• Psychiatry
• Public Health
• Epidemiology

Background:

• Gambling disorder (GD) is a recognized mental health condition.
• Comorbidities significantly impact patient outcomes and treatment efficacy.
• Understanding gender-specific patterns of comorbidities is crucial for targeted interventions.

Purpose of the Study:

• To investigate gender-specific standardized incidence ratios (SIRs) of comorbid psychiatric disorders in adults with GD.
• To examine mortality rates and causes of death in individuals diagnosed with GD.

Main Methods:

• A nationwide cohort study in Finland (2011-2022) included 3,605 adults diagnosed with GD (ICD-10 F63.0).
• Data were sourced from comprehensive social and healthcare registers.
• The general population (4,374,192 individuals) served as the reference group for SIR calculations.

Main Results:

• 88.5% of individuals with GD had at least one additional psychiatric disorder.
• Elevated incidence of psychiatric comorbidities was observed in the GD group compared to the general population.
• Personality disorders (PD), schizophrenia spectrum disorders (SSD), and substance use disorders (SUD) were more prevalent in the GD cohort, with specific gender patterns observed. Suicide accounted for 22% of deaths in the GD cohort (3.6% mortality rate).

Conclusions:

• Diagnosed GD is strongly associated with elevated rates of psychiatric disorders, especially PD, SSD, and SUD.
• Comprehensive mental health assessments are essential for individuals with GD.
• Healthcare professionals must be vigilant regarding the high prevalence of psychiatric comorbidities in this population to ensure timely and effective care.
