A comparison of inpatients with anxious depression to those with nonanxious depression

Anxiety symptoms are common for patients with major depressive disorder (MDD). Anxious depression has been considered MDD with high levels of anxiety symptoms. The objective of this study was to investigate the factors associated with anxious depression for Chinese inpatients with MDD. A total of 174 acutely ill patients were enrolled. Baseline demographic variables, suicide risk, depression severity, quality of life (QOL), and daily functional impairment were assessed. Those MDD patients with a 17-item Hamilton Depression Rating Scale (HAMD-17) anxiety/somatization factor score≥7 were defined as anxious depression. Logistic regression was employed to examine the factors associated with anxious depression. One hundred and forty-one (81.0%) of the subjects reported anxious depression. Patients with anxious depression were more likely to have melancholic features, to be older, to experience more severe depression, to be at greater risk of suicide, to have more pain, poorer quality of life, and more severe functional impairment. Anxious depression is common in inpatients with MDD. These findings suggest that anxious depression significantly differs from nonanxious depression on several clinically relevant variables. These data add to a growing body of evidence that anxious depression is a more complex presentation of depression.
