Common mental disorders and subsequent work disability: a population-based Health 2000 Study

Area of Science:

• Epidemiology
• Psychiatry
• Occupational Health

Background:

• Work disability due to common mental disorders has risen in Western nations.
• The population-level impact of depressive, anxiety, and alcohol use disorders on disability pensions remains unclear.

Purpose of the Study:

• To determine the contribution of common mental disorders to disability pensions.
• To identify predictors of work disability.

Main Methods:

• Utilized data from the Finnish Health 2000 Study (2000-2001) linked to disability pension records up to 2007.
• Assessed mental health using the Composite International Diagnostic Interview (CIDI) in 3164 participants aged 30-58.
• Employed logistic regression analyses with sociodemographic, clinical, work-related, and treatment factors as covariates.

Main Results:

• Anxiety, depressive, and comorbid mental disorders predicted disability pension.
• Comorbid mental disorders, physical illnesses, older age, lower education, high job strain, and prior long-term sickness absence were independent predictors of disability pension in the fully adjusted model.

Conclusions:

• Comorbid mental disorders represent a significant risk factor for disability pension.
• Work disability is influenced by sociodemographic, clinical, work-related, and treatment factors, but not health behaviors.
• Preventing chronic work disability necessitates increased focus on work-related factors.
