Objective: To examine the prevalence of depression in the last trimester of pregnancy and within the first 6 months postpartum, to determine whether there is an association between antepartum and postpartum depression and to investigate the risk factors prospectively in a cohort of Turkish women.
Study design: In a prospective, community-based, cohort study, 125 women who expected to give birth during the first 6 months of 2002 (January 1, 2002-June 30, 2002) were included. Depression was measured at 36-38 weeks antepartum and then again at 5-8, 10-14 and 20-26 weeks postpartum using the Edinburgh Postnatal Depression Scale. A questionnaire that was devised to collect data on sociodemographic and clinical information on the women was applied.
Results: The prevalence of depression was highest in pregnancy (21.6%) and declined gradually in the follow-up period (respectively, 16.8%, 14.4% and 9.6%). Antepartum depression was a statistically significant risk factor during the 6 months postpartum in each of the 3 assessments. In the logistic model, past history of mental illness, history of mental illness in first-degree relatives and adverse life events were associated with antepartum depression; low income, adverse life events and a poor relationship with the husband were associated with postpartum depression.
Conclusion: Evaluations made in'the last trimester of pregnancy should be very helpful in diagnosing and preventing depression in women at high risk.
