RESUMO
INTRODUCTION: The present study aimed to investigate the incidence rate of pregnancy-onset panic disorder (POPD) among Turkish pregnant women using a diagnostic interview. Additionally, we examined whether the independent socio-demographic or clinical risk factors were associated with the risk of panic disorder in these women. METHODS: The study sample comprised 1475 consecutive pregnant women who presented to the obstetric outpatient clinics of two research centers. The rate of POPD in these participants was 1.3% (Group 1, n=20). The 20 women with POPD were compared with 250 pregnant women without pregnancy-onset depression or anxiety (Group 2; controls). Panic disorder and other anxiety or mood disorders were determined by means of the Structured Clinical Interview for DSM-IV. Comorbid Axis II disorders were diagnosed with the Structured Clinical Interview for DSM-III-R Personality Disorders. RESULTS: The incidence rate of panic disorder was 1.3% (n=20). In group 1, 55% (n=11) of the women with POPD had an additional mood or anxiety disorder. In addition, the prevalence rate of any cluster C personality disorder, including avoidant, passive-aggressive and obsessive-compulsive personality disorders, were significantly greater in the group 1 women with POPD than the control pregnant women without a panic disorder (group 2). CONCLUSION: The women with POPD were more likely than the controls to have a cluster C Axis II disorder and a history of a pre-existing anxiety or mood disorder.
