Perinatal depressive symptoms among Thai women: A hospital-based longitudinal study.

The authors of this longitudinal study investigated risk factors for postpartum depressive symptoms and differences in depressive symptoms at late pregnancy and at 1 and 3 months postpartum. In Sakhonnakhon Province, in northeastern Thailand, 449 women were recruited during late pregnancy and followed at 1 and 3 months postpartum with the use of psychosocial factors. Depressive symptom scores were measured using the Edinburgh Postnatal Depression Scale (EPDS). The scores were compared using dependent-samples t-tests, and multiple linear regression analyses were used to identify risk factors for depressive symptoms at 1 and 3 months postpartum. EPDS scores decreased from late pregnancy to 1 month postpartum and remained on the same level until 3 months postpartum. Low psychological well-being scores and low personal monthly income were risk factors for increased EPDS scores at 1 and 3 months postpartum. Pregnant women in Thailand who have a low income, have limited social support, and report low psychological well-being are at increased risk for postpartum depression. Results of this study suggest they should be screened for depressive symptoms during pregnancy, referred for diagnosis, and provided treatment to reduce the risk of ongoing depressive symptoms during the postpartum period.
