Abstract

PURPOSE. This study aims to determine the 12-month and lifetime prevalence of generalized anxiety disorder (GAD) and its sociodemographic correlates.

DESIGN AND METHODS. A total of 5,926 subjects were randomly selected and interviewed.

FINDINGS. The overall 12-month and lifetime prevalence of GAD was 0.8%, and 1.2%, respectively. Being older than 25 years and female, lower education level, unemployed status, and lower (<RMB500/month) or higher (>RMB2000/month) monthly income were associated with increased risk of GAD.

PRACTICE IMPLICATIONS. The low percentage of subjects treated for GAD indicates a major public health problem that should be addressed.
