Prevalence, Course, and Risk Factors for Antenatal Anxiety and Depression

To estimate the prevalence and course of antenatal anxiety and depression across different stages of pregnancy, risk factors at each stage, and the relationship between antenatal anxiety and depression and postpartum depression.

A consecutive sample of 357 pregnant women in an antenatal clinic in a regional hospital was assessed longitudinally at four stages of pregnancy: first trimester, second trimester, third trimester, and 6 weeks postpartum. The antenatal questionnaire assessed anxiety and depression (using the Hospital Anxiety and Depression Scale) and demographic and psychosocial risk factors. The postpartum questionnaire assessed postpartum depression with the Edinburgh Postnatal Depression Scale.
