Abstract

AbstractIntroductionTo clarify whether the declaration of an emergency state due to the spread of COVID‐19 in Japan affected the number of maternal transports and premature births.MethodsA questionnaire‐based descriptive study was conducted in perinatal centers throughout Japan in 2020. The incidence of maternal transport and preterm delivery rates every month after the COVID‐19 spread in 2020 were compared with those in 2019.ResultsParticipants were recruited from 52 perinatal centres. The maternal transport rate (maternal transports per number of deliveries) was 10.6% in April and 11.0% in June 2020, compared with 12.5% in 2019 (P < 0.05). The maternal transport rate due to preterm labor was 4.8% in April 2020 and 5.8% in 2019 (P < 0.05). The maternal transport rate during the declaration of emergency state decreased by 21% in April 2020 in non‐emergency‐declared prefectures, and decreased by 17% in May 2020 in emergency‐declared prefectures. However, there was no significant difference in the preterm delivery rate between 2020 and 2019, regardless of the prefecture and gestational period.ConclusionDeclaration of the emergency status due to COVID‐19 spread in Japan reduced maternal transport due to preterm labor, but did not reduce preterm delivery itself.
