Obsessive-Compulsive Disorder in Singapore: Prevalence, Comorbidity, Quality o Life and Social Support

摘要

Introduction: Using data from Singapore Mental Health Study 2016 (SMHS 2016), we examined the prevalence of lifetime and 12-month obsessive-compulsive disorder(OCD), its sociodemographics correlates and association with comorbid psychiatric disorders and physical conditions, perceived social support and quality of life. Materials and Methods: The World Mental Health Com pos ite International Diagnostic Interview (version 3.0) was administered by trained interviewers to 6126 residents aged >= 18 years old to assess OCD prevalence and that of other select psychiatric disorders. Details on sociodemographics, perceived social support and health-related quality oflifewere obtained. Results: Lifetime and 12-month prevalence of OCD was 3.6% and 2.9%, respectively. Adjusted regression analysis showed that those with OCD had significantly higher odds of major depressive disorder (odds ratio [OR] 5.4), bipolar disorder (OR, 8.9), generalised anxiety disorder (OR, 7.3) and alcohol abuse (OR, 2.7). OCD was significantly associated with suicidal ideation and suicidality (OR, 5.1). OCD subjects also had higher odds of chronic pain (OR, 2.4) and diabetes (OR, 3.1). Finally, OCD subjects had loner mean mental composite summary scores than controls (respondents without any of the psychiatric disorders and physical conditions included in SMHS 2016) and those with other lifetime psychiatric disorders and physical conditions. Conclusion: OCD prevalence in Singapore is high. Most people with OCD do not seek treatment despiteexperiencing significant comorbid ity and loss of quality of life.
