Alcohol Use Disorders in Patients Suffering from Obsessive–Compulsive Disorder: A Cross-sectional Study

Background: Comorbidity in obsessive–compulsive disorder (OCD) is known, especially alcohol use disorders (AUDs) in OCD. Data are lacking regarding the prevalence, the obsessions and compulsions in people with OCD with comorbid alcohol use. Aims and Objectives: The aim was to study the prevalence of AUDs in people with OCD. The primary objective was to study the prevalence of AUDs in 100 people with OCD. Secondary objective was to study the clinical characteristics, obsessions, and compulsions of people with OCD and comorbid alcohol use. Settings and Designs: The study design was a cross-sectional study. Materials and Methods: 100 patients of Asha Hospital diagnosed with OCD were screened and included in the study after a written informed consent. YBOCS checklist and scoring were done. People satisfying the criteria for AUD were further assessed with SADQ questionnaire. SPSS software was used for statistical analysis. Results and Conclusions: The lifetime prevalence of substance use disorders was found 18%. Point prevalence of any substance use was 13%, out of which 7% had AUDs. 2% had a dependence pattern and 5% had an abuse pattern. When comparing people with alcohol versus non-alcohol use, there was a significant difference in the proportion of males in the alcohol group (P = 0.0011). Nicotine was used in higher proportion in the alcohol group (P = 0.0001). Alcohol users were not regular with medications (P = 0.01). Miscellaneous obsessions are more common in them (P = 0.002). Alcohol users had a higher proportion of nil compulsions (P = 0.057) implying that obsessions were more prominent than compulsions in them. Mean scores of OCD in both groups were around moderate severity, with no significant difference between the two.
