title: Impact of multiple births on late and moderate prematurity.
abstract: Multiple gestations have an increased risk of pregnancy complications compared with singletons. Delay in childbearing and assisted reproductive techniques have remained common reasons for the increase in multiple gestations over the last few decades. Higher rates of both spontaneous and indicated preterm birth in twins and triplets lead to a significant proportion of the moderate preterm birth and late preterm birth rates. The article is a review of the causes of preterm birth and morbidities associated with these pregnancies.
