Comparison of morbidity among twins and triplets.

This study aims to compare morbidity indicators between twins and triplets. This was a retrospective, observational study, and involved a review of twins and triplets born in Basildon Hospital between 1991 and 2000. The main outcome measures were mean birth weight, gestational age at delivery, mode of delivery and length of stay in the intensive care unit. The mean birth weight is comparable between twins and triplets (1.877 kg at 33+4 weeks of gestation vs. 1.905 kg at 34+4 weeks of gestation). Triplets stayed a longer period in the intensive care baby unit. In this study birth weight in multiple pregnancies was as expected for gestational age. Triplets required longer neonatal intensive care.
