A retrospective cohort study was conducted at a tertiary medical center in Israel from 1991 to 2021, comparing preterm twins vaginally delivered (VD) versus cesarean section, excluding cases with congenital malformations or perinatal deaths. Kaplan\u2013Meier survival curves were used to compare the cumulative incidence, and Cox proportional hazards models were applied to adjust for potential confounders. Four thousand twenty-eight preterm twin offspring were included, with 1703 (42%) VD and 2325 (58%) by CD. Preterm twins delivered by CD had a higher incidence of respiratory morbidities (42% vs. 35% in the VD group, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), with an adjusted Hazard Ratio (aHR) of 1.15 (95%CI 1.02\u20131.30). CD was associated with an increased incidence of neurologic morbidities (22% vs. 17% in the VD group, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), with an aHR of 1.16 (95%CI 1.02\u20131.36). CD was associated with a higher incidence of infectious morbidities (69% vs. 62%, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), with an aHR of 1.10 (95%CI 1.01\u20131.21). Gastrointestinal morbidities were more pronounced in the CD group (29% vs. 25%, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), but the multivariable analysis did not reach significance (aHR\u2009=\u20091.10, 95%CI 0.95\u20131.27). Sub-analyses of elective-uncomplicated deliveries showed consistent results for most morbidities. <jats:italic>Conclusions:<\/jats:italic> Cesarean delivery in preterm twins is associated with long-term respiratory, neurologic, infectious and gastrointestinal morbidities of the offspring.
