Abstract
ABSTRACTBackground:Comorbid anxiety disorders are common in late-life depression and negatively
impact treatment outcome. This study aimed to examine personality
characteristics as well as early and recent life-events as possible
determinants of comorbid anxiety disorders in late-life depression, taking
previously examined determinants into account.Methods:Using the Composite International Diagnostic Interview (CIDI 2.0), we
established comorbid anxiety disorders (social phobia (SP), panic disorder
(PD), generalized anxiety disorder (GAD), and agoraphobia (AGO)) in 350
patients (aged ≥60 years) suffering from a major depressive
disorder according to DSM-IV-TR criteria within the past six months.
Adjusted for age, sex, and level of education, we first examined previously
identified determinants of anxious depression: depression severity,
suicidality, partner status, loneliness, chronic diseases, and gait speed in
multiple logistic regression models. Subsequently, associations were
explored with the big five personality characteristics as well as early and
recent life-events. First, multiple logistic regression analyses were
conducted with the presence of any anxiety disorder (yes/no) as dependent
variable, where after analyses were repeated for each anxiety disorder,
separately.Results:In our sample, the prevalence rate of comorbid anxiety disorders in late-life
depression was 38.6%. Determinants of comorbid anxiety disorders were a
lower age, female sex, less education, higher depression severity, early
traumatization, neuroticism, extraversion, and conscientiousness.
Nonetheless, determinants differed across the specific anxiety disorders and
lumping all anxiety disorder together masked some determinants (education,
personality).Conclusions:Our findings stress the need to examine determinants of comorbid anxiety
disorder for specific anxiety disorders separately, enabling the development
of targeted interventions within subgroups of depressed patients.
