Prevalence of mood and anxiety disorders during pregnancy: A case-control study with a large sample size.

This study aimed to compare pregnant and non-pregnant women in terms of the current prevalence of mood and anxiety. The study sample included 1154 women evaluated on the first day postpartum and 328 control subjects. Mood and anxiety disorders were determined by structured psychiatric interview. The prevalence rate of any mood or anxiety disorder was 18.2% during pregnany. Generalized anxiety disorder, obsessive-compulsive disorder, panic disorder and comorbidity among anxiety disorders were more prevalent during pregnancy compared to the control subjects. The present results suggest that pregnant women may be at increased risk of depression and anxiety disorders.
