Both women and men with OCD had a significantly higher risk of dying by suicide than women and men from the general population. However, this risk was more pronounced for women than men with OCD (ORs=12.25 vs 8.44, respectively; P-value for χ2=0.002). This was also the case when considering suicide attempts; women in the OCD cohort had a higher risk as compared with men (ORs=5.99 vs 4.67, respectively; P-value for χ2<0.0001); this difference was driven by women being more likely to attempt suicide than men in the OCD group, but not in the general population cohort (Table 1). Patients with OCD were approximately 3 years younger than controls at the time of suicide (42.55 vs 45.45 years; P-value for t-test=0.003). On the other hand, patients with OCD were approximately 2 years older than controls when they first attempted suicide (30.31 vs 28.56 years; P-value for t-test<0.001) (Table 1). Individuals with OCD were more likely to have repeated attempts (more than two) than their matched controls (30.30% vs 16.03%, respectively; OR=2.07) (Table 1).
