Abstract

Background and objectives: Obsessive-compulsive disorder (OCD) is a disease that causes personal distress or social dysfunction, especially in childhood. The present study aimed to provide the prevalence, comorbidity, and predictors of OCD among children and adolescents. Methods: This was a cross-sectional national project conducted on 29,858 children and adolescents using the multi-stage cluster random sampling in Iran. There were both genders in each cluster and three age groups (6–9, 10–14, and 15–18 years) within each cluster. The tools used in this research included a demographic questionnaire and K-SADS-PL. To analyze the data, logistic regression and cross-tab tests were used. Results: According to the results, the prevalence of OCD in children and adolescents was 3.1 in boys and 3.8 in girls. Also, gender, age, place of residence, and history of psychiatric hospitalization of parents could predict OCD. OCD had comorbidity with behavioral disorders (OR = 0.60, 95%CI: 0.39–0.92), elimination disorders (OR = 0.50, 95%CI: 0.30–0.83), mood disorders (OR = 2.92, 95%CI: 1.43–5.94), and smoking and alcohol disorders (OR = 4.33, 95%CI: 1.28-14.63). Conclusion: In the development of the obsessive-compulsive disorder, other disorders and symptoms also environmental factors can play a role and are important. Based on our findings, given the prevalence rate of OCD was higher in the age groups of 10–14 and 15–18 years, are one of the most important stages of development for the prevention and treatment of mental disorders, especially OCD, clinical specialists can design appropriate clinical trials or modify existing interventions based on the results of such research. © 2021 Elsevier Ltd
