Background: Depression and anxiety are common among pregnant women. Internet-delivered psychological therapies such as cognitive behavioral therapy (iCBT) have been developed to increase accessibility and address common help-seeking barriers, especially during pandemic period. The objective of this trial is to evaluate the short-term and long-term effects of iCBT on reducing depressive symptoms among pregnant women during the COVID-19 pandemic with the overall goal of preventing depression recurrence in the first 12 months postpartum.Methods: A multi-site randomized controlled trial will be conducted where 300 pregnant women early in their third trimester will be screened for depression symptoms using the Edinburgh Postnatal Depression Scale (EPDS) during a routine obstetrical visit. Eligible and consenting women with a score greater than 9 will be randomly allocated (1:1) to either intervention group or control group. ICBT involving the completion of 7 weekly online modules will be delivered via a well-designed perinatal mental healthcare app. The primary objective is to evaluate the effect of iCBT on reducing depression symptoms among pregnant Chinese women starting from their third trimester. The secondary objectives are to examine the effect of iCBT on anxiety, sleep quality, social support, parenting stress, co-parenting relationship, and infant development.Discussion: This multi-center randomized controlled trial has been planned in accordance with best practices in behavioral trial design. The internet-based intervention addressed the needs of pregnant women during a major pandemic where face-to-face therapy is not preferable. The trial has a relatively large sample size with sufficient power to evaluate the efficacy of iCBT intervention for the primary and secondary outcomes. One year follow-up evaluation in the study is designed to determine the longer-term effect of the intervention on both maternal and infant outcomes. Although a limitation is the assessment of depression and anxiety using self-report measures, these easily incorporated and maternal-preferred assessments allow for real-life scalability if the intervention is proven to be effective.Ethics and Dissemination: Ethics was approved by the institutional review board of International Peace Maternity and Child Health Hospital (GKLW2020-25). Dissemination of results will be published in peer-reviewed academic journals and presented at scientific conferences.Trial Status: The first patient was enrolled on 19 August 2020. To date, 203 participants have met eligibility requirements and been randomized to either the intervention group or control group. Data collection aims to be complete in September 2022.

Antenatal depression might cause adverse pregnancy outcomes. However, previous study results were inconsistent, especially in the low- and middle- income countries. We aimed to study the association between antenatal depression and adverse perinatal outcomes in a Chinese population. We performed a prospective cohort study and enrolled pregnant women from January 2020 to January 2021. Antenatal depressive symptoms in the third trimester of pregnancy were evaluated by the Edinburgh Postpartum Depression Scale (EPDS). Baseline characteristics and pregnancy outcomes were recorded. After adjusting for confounding factors (age, occupation, education level, and annual income), multivariate logistic regression analysis was applied to evaluate the associations between antenatal depression and pregnancy outcomes. Among the 5209 participants, 1448 (27.7 %) pregnant women were positive for depression. After adjusting for potential confounders, women with antenatal depressive symptoms were significantly more likely to deliver prematurely [Odds ratio (OR) = 1.404, 95 % confidence interval (CI) = 1.020–1.933, P = 0.037] and receive cesarean section (OR = 1.154, 95 % CI = 1.002–1.331, P = 0.048). EPDS, not a structured diagnostic interview, was used for psychological assessment. In addition, we only screened the women in their third trimester in a single research center. The association between the duration of antenatal depression and perinatal outcomes was not evaluated. Depressive symptoms were common among Chinese women in their third trimester of pregnancy. Women with antenatal depressive symptoms had increased cesarean section and preterm delivery risks. Screening and treatment for antenatal depression are needed during the prenatal care.
