A Case-Control Study of Trichotillomania Patients Using a National Database.

Area of Science:

• Psychiatry
• Behavioral Science
• Genetics

Background:

• Trichotillomania (TTM) is a body-focused repetitive disorder with known psychiatric comorbidities.
• Limited comprehensive studies exist on the broad range of TTM's associations.

Purpose of the Study:

• To investigate the associations between TTM and psychiatric, neurodevelopmental, substance-related, reproductive, and social factors.
• To utilize a national database for a comprehensive analysis of TTM comorbidities.

Main Methods:

• A case-control study was conducted using the All of Us Research Program database.
• 40 TTM cases were matched with 400 controls based on age, sex, and ethnicity.
• Multivariate logistic regression analyzed associations with comorbidities and lifestyle factors, controlling for demographics.

Main Results:

• TTM showed significant associations with obsessive-compulsive disorder (OR 18.3), borderline personality disorder (OR 15), anxiety disorders (OR 10.2), alcohol abuse (OR 6.13), and depression (OR 5.89).
• Other significant associations included vitamin D deficiency (OR 4.2), fatigue, social anxiety, post-traumatic stress disorder, ADHD, and difficulty with independent errands.

Conclusions:

• The study confirms strong links between TTM and various psychiatric and behavioral conditions.
• Findings underscore the necessity for integrated treatment approaches addressing both psychiatric and physical health aspects in TTM management.
