摘要

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.
