Abstract

Background:

Little is known about the effects of age on the symptoms of anxiety disorder. Accordingly, this study sought to investigate age-related differences in the number and kind of symptoms that distinguish between individuals with and without a diagnosis of generalized anxiety disorder (GAD).

Methods:

A sample of 3,486 self-reported worriers was derived from Wave 1 of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC), an epidemiological survey of mental health conducted in the USA in 2001–2002. Participants were stratified into the following age groups (18–29 years, 30–44 years, 45–64 years, 65–98 years), and then divided into diagnostic groups (GAD and non-GAD worriers).

Results:

Binary logistic regression analyses revealed that four distinct sets of symptoms were associated with GAD in each age group, and that numerically fewer symptoms were associated with GAD in older adults. Moreover, there were graduated changes in the type and number of symptoms associated with GAD in each successive age group.

Conclusions:

There are graduated, age-related differences in the phenomenology of GAD that might contribute to challenges in the detection of late-life anxiety.
