Ethnicity and Psychiatric Disorders.

Area of Science:

• Global Mental Health
• Psychiatric Epidemiology
• Sociology of Health

Background:

• Psychiatric disorders are a leading cause of global disability.
• Ethnic variations in mental health disorders are understudied, particularly in South Asia.
• Understanding these variations is crucial for targeted public health interventions.

Purpose of the Study:

• To investigate ethnic differences in the prevalence of specific psychiatric disorders in Nepal.
• To examine variations in Major Depressive Episode (MDE), Major Depressive Disorder (MDD), Panic Attack, Panic Disorder, Post-Traumatic Stress Disorder (PTSD), and Intermittent Explosive Disorder (IED).

Main Methods:

• Utilized data from 400 adult interviews in Nepal using a controlled comparison design.
• Employed multilevel logistic regression models to analyze ethnic group differences.
• Used clinically validated World Mental Health survey instruments for diagnosis.

Main Results:

• Dalit populations exhibited significantly higher odds for most psychiatric disorders and episodes compared to the Brahmin/Chhetri group.
• Janajati populations showed significantly lower odds of being diagnosed with PTSD relative to the Brahmin/Chhetri group.
• No significant gender differences were observed for MDD or MDE.

Conclusions:

• Psychiatric disorders and episodes demonstrate significant ethnic variation within a rural South Asian population.
• Ethnicity is a significant factor influencing mental health outcomes in Nepal.
• Gender differences in the prevalence of depression were minimal in this study population.
