Objective. To assess morbidity and mortality in twin pregnancy deliveries, according to chorionicity and mode of delivery. Design. Population-based retrospective cohort. Setting. 14 obstetric departments in Denmark. Population. 1 175 twin pregnancies with two live fetuses at 36 + 0 weeks of gestation. Methods. Pregnancy outcomes assessed according to chorionicity and mode of delivery. Main Outcome Measures. Poor outcome defined as five-min-Apgar score≤7, umbilical artery pH<7.10, admission to neonatal unit >3 days or death. Results. Dichorionic (DC) twins, delivered after 36 gestational weeks, with intended vaginal delivery (n = 689) compared to DC twins with planned cesarean section (n = 371) had an increased risk of poor outcome (OR 1.47, p = 0.037) after adjustment for BMI, parity and weight discordance. There was no increased risk for poor outcome in MC twins with intended vaginal delivery (n = 63) compared to planned cesarean section (n = 52) [odds ratio (OR 0.87; 95% confidence interval (CI) 0.26-2.96)]. Nulliparity increased the risk of poor outcome in DC (OR 1.5; p = 0.03) and in MC twins (OR 4.01; p = 0.02), as well as birthweight discordance > 300 gram (DC (OR 1.50; p = 0.02) and MC (OR 6.02; p = 0.002)). For DC twins we found a significantly higher risk of poor outcome of the second born twin, compared to the first (OR 1.64; p = 0.001). Conclusion. DC twins born after 36 weeks of gestation had a higher risk of poor outcome by intended vaginal delivery than by planned cesarean section. For MC twins, statistical differences in outcome by mode of delivery, could not be reached.
