  • AbstractObjective: In the last few decades, attention has been focused on morbidity and mortality associated with late preterm delivery (34–36 + 6/7 weeks), accounting for 60–70% of all preterm births. This study is aimed to determine (1) the prevalence of late preterm deliveries (spontaneous and medically indicated) in our population; and (2) the rate of neonatal morbidity and mortality as well as maternal complications associated with the different phenotypes of late preterm deliveries.Study design: This retrospective population-based cohort study, included 96,176 women who had 257,182 deliveries, occurred between 1988 and 2011, allocated into three groups: term (n = 242,286), spontaneous (n = 10,063), and medically indicated (n = 4833) late preterm deliveries.Results: (1) Medically indicated late preterm deliveries were associated with increased maternal morbidity, as well as neonatal morbidity and mortality, in comparison with other study groups (p < .01 for all comparisons); (2) medically indicated l...
