Depressive symptoms during pregnancy and postpartum: associations with mode of conception and demographic and obstetric factors.

Abstract

An increasing number of women are conceiving through assisted reproductive technology; however, few studies have investigated their mental health after successful conception. This study investigated the changes in depressive symptoms in women using assisted reproductive technology and the association between the mode of conception and perinatal depressive symptoms. A longitudinal observational study was conducted from 2015 to 2019, 542 pregnant women completed questionnaires on depressive symptoms at eight timepoints during the prepregnancy, pregnancy and first-year postpartum periods. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. A generalized estimating equation regression model was employed for repeated measures. In the assisted reproductive technology group, depressive symptoms were more prevalent during early pregnancy and at 1 month postpartum than before pregnancy, and more prevalent before pregnancy and at 1 month after childbirth than in the spontaneous conception group. No significant association was identified between the mode of conception and depressive symptoms during the antenatal or postnatal period. The lack of full-time employment and prepregnancy depressive symptoms were associated with antenatal depressive symptoms. Primipara status and depressive symptoms during prepregnancy and pregnancy were associated with depressive symptoms during the first-year postpartum. Assisted reproductive technology was not a risk factor for depressive symptoms during the pregnancy and postpartum periods, whereas primipara status, lack of full-time employment and prepregnancy depressive symptoms were negative predictors. Therefore, targeted mental health interventions should address these specific factors to effectively support maternal mental health.
