Psychiatric disorders in an Arctic community

Area of Science:

• Psychiatry
• Epidemiology
• Arctic Health

Background:

• Mental health disorders pose a significant challenge in remote communities.
• Previous research on Native mental health may underestimate current prevalence rates.

Purpose of the Study:

• To ascertain the prevalence of depression, anxiety, and alcohol abuse in an Arctic community.
• To utilize modern diagnostic criteria for accurate assessment.
• To provide updated mental health statistics for this specific population.

Main Methods:

• A random sample of 14-85 year old residents in an Arctic community participated.
• A two-step cross-sectional survey employed self-report questionnaires, including the Hospital Anxiety and Depression Scale (HADS) and the CAGE questionnaire.
• Validated screening instruments against the Structured Clinical Interview for the DSM-III-R (SCID) in a subsample.

Main Results:

• Anxiety prevalence was estimated at 19.0% within the past week.
• Depression prevalence was estimated at 26.5% within the past week.
• Lifetime alcohol abuse was estimated at 30.5%.

Conclusions:

• The prevalence of psychiatric disorders in this Arctic community exceeds previous estimates for Native mental health.
• Findings highlight the need for targeted mental health interventions in Arctic regions.
• This study provides crucial data for public health planning and resource allocation.
