Perinatal Outcomes during versus Prior to the COVID-19 Pandemic and the Role of Maternal Depression and Perceived Stress: A Report from the ECHO Program

Objective We sought to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on perinatal outcomes while accounting for maternal depression or perceived stress and to describe COVID-specific stressors, including changes in prenatal care, across specific time periods of the pandemic.Study Design Data of dyads from 41 cohorts from the National Institutes of Health Environmental influences on Child Health Outcomes Program ( N = 2,983) were used to compare birth outcomes before and during the pandemic ( n = 2,355), and a partially overlapping sample ( n = 1,490) responded to a COVID-19 questionnaire. Psychosocial stress was defined using prenatal screening for depression and perceived stress. Propensity-score matching and general estimating equations with robust variance estimation were used to estimate the pandemic's effect on birth outcomes.Results Symptoms of depression and perceived stress during pregnancy were similar prior to and during the pandemic, with nearly 40% of participants reporting mild to severe stress, and 24% reporting mild depression to severe depression. Gestations were shorter during the pandemic ( B = - 0.33 weeks, p = 0.025), and depression was significantly associated with shortened gestation ( B = - 0.02 weeks, p = 0.015) after adjustment. Birth weights were similar ( B = - 28.14 g, p = 0.568), but infants born during the pandemic had slightly larger birth weights for gestational age at delivery than those born before the pandemic ( B = 0.15 z-score units, p = 0.041). More women who gave birth early in the pandemic reported being moderately or extremely distressed about changes to their prenatal care and delivery (45%) compared with those who delivered later in the pandemic. A majority (72%) reported somewhat to extremely negative views of the impact of COVID-19 on their life.Conclusion In this national cohort, we detected no effect of COVID-19 on prenatal depression or perceived stress. However, experiencing the COVID-19 pandemic in pregnancy was associated with decreases in gestational age at birth, as well as distress about changes in prenatal care early in the pandemic.

Automated summary

During the COVID-19 pandemic, pregnant women experienced similar levels of prenatal depression and perceived stress compared to before the pandemic. However, gestational age at birth was shorter and depression was associated with shortened gestation. Birth weights did not differ significantly, but infants born during the pandemic had slightly larger birth weights for gestational age. More women who gave birth early in the pandemic reported being moderately or extremely distressed about changes in prenatal care and delivery. The majority reported negative views of the impact of COVID-19 on their life.
