Background & Aims: Postnatal depression (PND) is a common illness that requires early intervention. However, women’s postpartum difficulties are often overlooked. This study aims to identify the risk factors of PND based on data obtained from general obstetrics in a maternity hospital. It also explores the usefulness of the Distress and Impact Thermometer (DIT) as a simple PND screening tool.
Methods: The sample comprised 423 women who had undergone parturition in a private hospital between January to June 2016. The participants were first assessed at a few days and then one month postpartum using self-administered questionnaires. The risk factors of PND were examined using logistic regression analysis while the DIT was assessed using the receiver operating characteristic (ROC) curve for PND.
Results: Depressive symptoms during early postpartum, psychiatric illness history, and primipara were significant risk factors for PND. Epidural delivery significantly reduced the risk of PND in women with early postpartum depressive symptoms. The PND detection test in the DIT had an area of 0.85 under the ROC curve.
Conclusions: Women with early postpartum depressive symptoms or a psychiatric illness history require continuous monitoring and support. Further, the DIT can be a useful screening tool for PND.
