Abstract

Hypothesis: Increased social distancing was associated with a lower incidence of extremely preterm live births (EPLB) during the initial COVID-19 pandemic period.

Study design: Prospective study at the NICHD Neonatal Research Network sites comparing EPLB (220/7-286/7 weeks) and extremely preterm intrapartum stillbirths (EPIS) rates during the pandemic period (March-July, weeks 9-30 of 2020) with the reference period (same weeks in 2018 and 2019), correlating with state-specific social distancing index (SDI).

Results: EPLB and EPIS percentages did not significantly decrease (1.58-1.45%, p = 0.07, and 0.08-0.06%, p = 0.14, respectively). SDI was not significantly correlated with percent change of EPLB (CC = 0.29, 95% CI = -0.12, 0.71) or EPIS (CC = -0.23, 95% CI = -0.65, 0.18). Percent change in mean gestational age was positively correlated with SDI (CC = 0.49, 95% CI = 0.07, 0.91).

Conclusions: Increased social distancing was not associated with change in incidence of EPLB but was associated with a higher gestational age of extremely preterm births.

Fig. 1. Correlation of social distancing index with percent change in extremely preterm live births and intrapartum stillbirths.
The percent change from reference period ((pandemic – reference)/reference*100) was calculated using the weekly rates of EPLB and EPIS. The social distancing index was not significantly correlated with the percent change of extremely preterm live births (CC = 0.29, 95% CI = −0.12, 0.71) and intrapartum stillbirths (CC = −0.23, 95% CI = −0.65, 0.18). Reference period: calendar weeks 9–30 of 2018 and 2019 pandemic period: calendar weeks 9–30 of 2020.

The percent change from reference period ((pandemic – reference)/reference*100) was calculated using the weekly average gestational age. The social distancing index was positively correlated with extremely preterm birth gestational age (CC = 0.49, 95% CI = 0.07, 0.91). Reference period: calendar weeks 9–30 of 2018 and 2019 pandemic period: calendar weeks 9–30 of 2020.
