Adjusted for sociodemographic variables, the all-cause MRR for persons with OCD was 2.14 (95% CI, 1.76–2.57) compared with persons from the general population without this diagnosis (Table 2). Additional adjustment for somatic comorbidity reduced the MRR to 2.00 (95% CI, 1.65–2.40). Although diagnoses of OCD were consistently associated with higher mortality rates, time since first diagnosis did not have a significant effect (eTable in the Supplement). The interaction between sex and OCD, although clinically relevant, was not statistically significant (P = .63). The fully adjusted MRR for women with OCD (1.63 [95% CI, 1.26–2.06]) was only marginally lower than the MRR for men (1.75 [95% CI, 1.30–2.31]) (Table 2). Restricting the cohort to persons younger or older than 45 years of age resulted in MRRs similar to those obtained from the overall cohort.
