Prevalence of anxiety disorders among elderly people

The objectives of this study are to determine current and lifetime prevalence of anxiety disorders and also to explore the relationship, if any, between possible risk factors and anxiety disorders, amongst elderly people living in the Sivas province of Turkey.

The research sample consisted of 462 persons. A Socio-demographic Data Form was given to the participants and the Anxiety Module of SCID-I was applied. Chi-square and Fischer's exact tests were used to evaluate the data obtained.

The current prevalence for all types of anxiety disorder was found to be 17.1% overall and the lifetime prevalence was found to be 18.6%. The current prevalence rates for particular disorders were found to be 0.4% for panic disorder, 3.2% for obsessive-compulsive disorder, 1.9% for post-traumatic stress disorder, 2.8% for social phobia, 11.5% for specific phobia, 6.9% for generalized anxiety disorder (GAD). Lifetime prevalence rates for these disorders (except GAD) were 1.1%, 3.2%, 3.0%, 2.85%, 11.5% respectively.

Anxiety disorders are more common among elderly people than was previously thought. The lifetime prevalence of specific phobia amongst the elderly is higher than that of general population; the lifetime prevalence ratios of obsessive-compulsive disorder and social phobia are similar to that of the general population in Sivas. In order to improve the delivery of health services, it is recommended that further studies should be conducted among elderly people, both by applying standardized diagnostic tools, but also taking into account socio-economic factors and using convenient therapy methods developed specifically for this group.
