Effects of psychiatric disorders on ultrasound measurements and adverse perinatal outcomes in Chinese pregnant women: A ten-year retrospective cohort study.

Background: Placental health and serial fetal ultrasound parameters deficits in fetal development in women with psychiatric disorders have yet to be understood. This study aimed to examine the effects of psychiatric disorders on placental health, ultrasound measurements, and adverse perinatal outcomes among Chinese pregnant women.

Methods: All the pregnant women with psychiatric disorders who delivered at Women's Hospital School of Medicine, Zhejiang University, China, between 2010 and 2020 were included. A total of 992 women (716 in the healthy control group and 276 in the psychiatric disorders group) were recruited. Outcomes include maternal and neonatal birth outcomes. Linear and logistic regression models were used to determine the beta (β) and odds ratios (OR) across 2 models after adjusting for multiple covariates.

Results: For women with psychiatric diagnoses, the mean placental measurements and serial fetal ultrasound parameters, and neonatal birth weight were lower than general pregnant women. After controlling the use of psychotropic medication during pregnancy, women with psychiatric diagnoses showed higher rates of placental implantation abnormalities or placental adhesion (OR = 5.724, 95% CI = [1.805, 15.408]), gestational diabetes mellitus (OR = 3.861, 95% CI = [2.109, 7.068]), anemia in pregnancy (OR = 4.944, 95% CI = [2.306, 10.598]), preterm birth <37 weeks' gestation (OR = 3.200, 95% CI = [1.702, 6.016]), low birth weight (OR = 11.299, 95% CI = [4.068, 31.386]), and neonatal intensive care unit admission (OR = 3.143, 95% CI = [1.656, 5.962]) compared to women in the healthy control group.

Conclusion: Pregnant women with psychiatric disorders were more likely to have poor placental outcomes, more ultrasound parameter abnormalities and obstetrical complications, and a higher risk for adverse birth outcomes.
