ABSTRACT

AIMS: There is ongoing debate about the extent to which the epidemiology of OCD is similar across the world, given the lack of nationally representative data from key regions like the Middle East and North Africa. Using the nationally representative dataset from the Saudi National Mental Health Survey (SNMHS), we aimed to delineate the epidemiological profile of OCD in the Saudi population.

METHODS: A subsample of 1981 participants from the SNMHS was assessed. Prevalence estimates and correlates of OCD were determined using logistic regressions and cross tabulations.

RESULTS: The lifetime, 12-month, and 30-day prevalence estimates for OCD were 4.2%, 1.8%, and 1.6%, respectively, with hoarding being the most common symptom dimension. The mean age-of-onset of OCD was 16.8 years. In over two-thirds of respondents with lifetime (72.2%) or 12-month (71.2%), OCD was accompanied by comorbid mental disorder, particularly impulse control, anxiety, and mood disorders. Among individuals with 12-month OCD, 77.5% reported severe impairment, and only 9.2% received treatment.

CONCLUSIONS: In Saudi Arabia, OCD is a prevalent and persistent condition, characterized by early onset, high odds of mental comorbidity, and significant associated impairment. These findings emphasize the universality of OCD epidemiology and the need for improved diagnosis and treatment globally.
