Background: Previous work has suggested that anxiety disorders are associated with suicide attempts. However, many studies have been limited by lack of accounting for factors that could influence this relationship, notably personality disorders. This study aims to examine the relationship between anxiety disorders and suicide attempts, accounting for important comorbidities, in a large nationally representative sample. Methods: Data came from the National Epidemiologic Survey on Alcohol and Related Conditions Wave 2. Face-to-face interviews were conducted with 34,653 adults between 2004 and 2005 in the United States. The relationship between suicide attempts and anxiety disorders (panic disorder, agoraphobia, social phobia, specific phobia, generalized anxiety disorder, posttraumatic stress disorder (PTSD)) was explored using multivariate regression models controlling for sociodemographics, Axis I and Axis II disorders. Results: Among individuals reporting a lifetime history of suicide attempt, over 70% had an anxiety disorder. Even after adjusting for sociodemographic factors, Axis I and Axis II disorders, the presence of an anxiety disorder was significantly associated with having made a suicide attempt (AOR=1.70, 95% confidence interval (CI): 1.40–2.08). Panic disorder (AOR=1.31, 95% CI: 1.06–1.61) and PTSD (AOR=1.81, 95% CI: 1.45–2.26) were independently associated with suicide attempts in multivariate models. Comorbidity of personality disorders with panic disorder (AOR=5.76, 95% CI: 4.58–7.25) and with PTSD (AOR=6.90, 95% CI: 5.41–8.79) demonstrated much stronger associations with suicide attempts over either disorder alone. Conclusion: Anxiety disorders, especially panic disorder and PTSD, are independently associated with suicide attempts. Clinicians need to assess suicidal behavior among patients presenting with anxiety problems. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [ABSTRACT FROM AUTHOR]

The article discusses the results of a community survey assessing the relationship between anxiety disorders and physical conditions. The presence of an anxiety disorder was significantly associated with thyroid disease, respiratory disease, arthritis, gastrointestinal disease, migraine headaches, and allergic conditions. Evidence showed that anxiety disorders were independently associated with poor quality of life and disability.

Abstract: Background: Anxiety disorders and insomnia are each prevalent, impairing, and highly comorbid. However, little is known about whether specific types of sleep complaints are associated with specific anxiety disorders, and whether poor sleep has an additive effect on functional impairment in anxiety disorders. Method: Data from the German Health Survey (GHS; N =4181; ages 18–65) were utilized to examine relationships among anxiety disorders, sleep quality (assessed by the Pittsburgh Sleep Quality Inventory; PSQI), and functional impairment (assessed by the Medical Outcomes Scale Short Form; SF-36; and past-month disability days due to physical and emotional problems, respectively). Results: Most anxiety disorders were significantly associated with global PSQI scores. Social phobia (AOR 3.95, 95% CI 1.73–9.04) and GAD (AOR 3.94, 95% CI 1.66–9.34) had the strongest relationships with global PSQI scores. Daytime dysfunction was the PSQI subscale most strongly associated with anxiety disorders, particularly GAD. Having a comorbid anxiety disorder and poor sleep was associated with significantly lower Mental Component Scores on the SF-36 than having an anxiety disorder alone (40.87 versus 43.87, p =.011) and with increased odds of one or more disability days due to emotional problems (AOR 2.72, 95% CI 1.35–5.48), even after controlling for sociodemographic factors and past-month mood and substance use disorders. Conclusions: Most anxiety disorders are moderately associated with reduced sleep quality. Individuals with anxiety disorders and poor sleep experience significantly worse mental health-related quality of life and increased disability relative to those with anxiety disorders alone.
