However, nationally representative epidemiological data on OCD are not yet available in China. Aims: To investigate the prevalence, comorbidity, role impairment and healthcare utilisation of OCD in China. Methods: The present study used a multistage clustered area probability sample to obtain representative population-based data of adults from 157 nationwide disease surveillance points across 31 provinces in China. Trained interviewers conducted face-to-face interviews with respondents to collect information based on the Composite International Diagnostic Interview 3.0. Data weighting was performed to account for differential selection probabilities and response rates, and to post-stratify the sample to ensure its representativeness of the population in China. Results: A total of 28 140 respondents (12 537 (44.55%) males and 15 603 (55.45%) females) completed the diagnostic interview. Two-thirds of the respondents with lifetime OCD had comorbid mental disorders, with OCD typically emerging later than the comorbidities. The most common comorbidities were mood disorders (39.67%, odds ratio (OR): 9.60, 95% confidence interval (CI 7.35 to 12.53) and anxiety disorders (32.75%, OR: 13.33, 95% CI 10.14 to 17.52).
