Comorbidity of obsessive-compulsive disorder and symptoms with nicotine dependence: Observational epidemiologic evidence from US-representative and psychiatric outpatient population-based samples

Global prevalence of smoking among individuals with obsessive-compulsive disorder and symptoms: a systematic review and meta-analysis

Disease from nicotine dependency continues to be a leading cause of preventable death worldwide, and therefore research that elucidates potential correlates of tobacco use may facilitate the advancement of research, clinical practice, and policy in this area to target this public health challenge. One potential tobacco use correlate is obsessive-compulsive disorder (OCD) phenomena. The growing research evidence on the association between tobacco use and OCD phenomena is mixed, making it difficult to synthesize extant findings into meaningful conclusions. Indeed, there has never been a systematic review or meta-analysis of this area of research. To this end, a systematic review was carried out with studies between 1988 and 2021, and from this review, 71 independent estimations (n = 10,475; Females = 51.95%; mean age = 37.29, SD = 13.78) were extracted for meta-analysis. We found that about three in ten participants with OCD are likely to use tobacco, which is higher than the general population. The prevalence was the same among OCD participants at all levels (those with symptomology but no confirmed diagnosis, those surpassing a clinical cutoff for OCD but no confirmed diagnosis, and those with a confirmed OCD diagnosis). The results also indicated considerable variability across study results and a wide confidence interval associated with the tobacco use prevalence rate among those with OCD phenomena. The findings provide support for continued study of this comorbidity, perhaps with longitudinal and experimental designs to test for reciprocal associations between tobacco use and OCD phenomena in the service of targeting nicotine dependence as a substantial global public health concern.

Religious Involvement and DSM-IV Anxiety Disorders Among African-Americans

ABSTRACT

This study examined the relationship between eight measures of religious involvement and five anxiety disorders among a nationally representative sample of African-Americans ( N = 3403). The Diagnostic and Statistical Manual of Mental Disorders, 4th Edition , World Mental Health Composite International Diagnostic Interview was used to assess 12-month and lifetime prevalence for each disorder. Logistic regression indicated weekly service attendance was inversely associated with 12-month and lifetime panic disorder, lifetime agoraphobia, and 12-month and lifetime posttraumatic stress disorder (PTSD). Prayer was inversely associated with 12-month agoraphobia, 12-month social phobia, and lifetime PTSD. Listening to religious radio and looking to God for strength were also inversely related to, respectively, 12-month and lifetime panic disorder. Conversely, reading religious materials was positively associated with 12-month panic disorder, 12-month agoraphobia, lifetime PTSD, and lifetime generalized anxiety disorder. The results are discussed in light of conceptual models that specify multiple and sometimes divergent pathways through which religion impacts health, and suggestions for clinicians addressing anxiety disorders are delineated.
