This is a supra\u2010regional tertiary perinatal centre. Logistic regressions were used to examine singleton live preterm birth rates during the beginning of COVID\u201019 restrictions (16 March\u201017 April; \u2018early\u2019; 6955 births) and during the strictest part of COVID\u201019 restrictions (30 March\u20101 May; \u2018late\u2019; 6953 births), according to gestational age subgroups and birth onset (planned or spontaneous). We adjusted for multiple covariates, including maternal age, body mass index, ethnicity, parity, socioeconomic status, maternal asthma, diabetes mellitus and\/or hypertensive disorder.
