Association between antenatal depression and adverse perinatal outcomes: a prospective cohort study.

BACKGROUND: 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. METHODS: 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. RESULTS: 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). LIMITATIONS: 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. CONCLUSIONS: 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.

[Factors related to clinical pregnancy outcomes of in vitro fertilization-embryo transfer in women with secondary infertility].

OBJECTIVE: To investigate the factors related to clinical pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET) in women with secondary infertility. METHODS: The clinical, laboratory and follow-up data of 1129 cycles in 1099 patients with secondary infertility undergoing IVF-ET in Women's Hospital, Zhejiang University School of Medicine between July 2012 to July 2014 were retrospectively reviewed. The factors related to pregnancy outcomes were analyzed by univariate and logistic regression methods. The clinical pregnancy rates in women with different age and different number of embryos transferred were compared. The clinical outcomes of stimulation with gonadotropin releasing hormone (GnRH) agonist long protocol, GnRH agonist short protocol and GnH antagonist protocol were evaluated in secondary infertile patients aged ≥ 40 years. RESULTS: Among 1129 cycles, 376 cases (33.30%) had clinical pregnancy and 753 cases (66.70%) had no clinical pregnancy. There were significant differences in age, body mass index, basal follicle-stimulating hormone level, antral follicle number,paternal age and number of embryos transferred between pregnancy and no pregnancy groups (P<0.05); while only maternal age (OR=0.900, 95% CI: 0.873~0.928, P<0.001) and the number of embryos transferred (OR=2.248, 95% CI: 1.906~2.652, P<0.001) were the independent factors affecting the clinical pregnancy outcome of IVF-ET. There was no significant difference in clinical pregnancy rate between women aged 30~40 years with two embryos transferred and those aged<30 years with two or three embryos transferred(P>0.05). There were no significances in clinical pregnancy rate among women aged ≥ 40 years using GnRH agonist long protocol,GnRH agonist short protocol and GnRH antagonist protocol for stimulation (P>0.05). CONCLUSION: Maternal age and number of embryos transferred have independent effect on IVF-ET clinical pregnancy outcome of secondary infertile women. We suggest that no more than two embryos should be transferred for women in their thirties to minimize the risk of multiple pregnancy while still having an acceptable pregnancy rate. The pregnancy rate of patients over 40 years decreases significantly, and there is no difference in pregnancy rate by using GnRH agonist long protocol, GnRH agonist short protocol or GnRH antagonist protocol.
