Aim/background: Gender is related to differences in the prevalences, manifestations and comorbidities of mental disorders. Findings on the effect of sex on adults with obsessive-compulsive disorder (OCD) are limited and inconsistent. We aimed to compare male and females with OCD in a large sample of adults.
Methods: We included 559 patients with OCD (299 females, 50.68%). We employed the Yale-Brown Obsession and Compulsion Scale (Y-BOCS), Hamilton Depression Rating Scale-17 (HDRS-17) and Beck Anxiety Inventory (BAI). We gathered data about the onset of illness, the years of education, marital status, long-term unemployment, history of hospitalization and suicide attempts, lifetime attention deficit and hyperactivity disorder (ADHD), tic disorder, alcohol use disorder (AUD), substance use disorder (SUD), smoking and symptom dimensions.
Results: The Y-BOCS, HDRS-17 and BAI scores were significantly higher in women. Men were characterized by earlier onset of OCD, younger age, longer years of education, higher prevalence of past or current tic disorders and higher frequency of AUD/SUD and smoking. Ratio of being married was higher among women whereas most of males were never-married. History of suicide attempt was more common among women.
Conclusions: Our research offers additional support for variations in clinical characteristics of OCD based on gender. It is essential to investigate the biological foundation of gender differences on OCD.
