Comparison between singleton- and triplet-specific “growth” curves to detect growth restricted triplet infants

Objective: To evaluate whether triplet- or singleton-specific growth standards should be used to define the growth restricted triplet fetus/neonate.

Study design: We retrospectively compared the predictive values of singleton vs...

Gestational age-specific distribution of twin birth weight discordance

Aim: To examine the gestational age-specific distribution of twin birth weight discordance.

Methods: We analyzed all liveborn twin sets between 28 and 40 weeks' gestation from the United States 1995–1998 Multiple Matched Birth Data Set compiled by the National Center for Health Statistics...

Slow change in body mass index during early triplet pregnancy is associated with decreased birth weight

Objective: This study evaluates the impact of an average change in body mass index (BMI) during the first 16–25 weeks on outcomes of triplet pregnancies.

Study design: In this retrospective observational study we evaluated a cohort of triplets born to 1235 nulliparas and 705 multiparas...

The Northwestern twin chorionicity study: testing the ‘placental crowding’ hypothesis

Objective: To evaluate the relation between placental proximity and frequency of birth weight discordance and small-for-gestational age (SGA) infants.

Study design: Retrospective three-tier chorionicity analysis of 1155 twin placentas comparing birth weight characteristics of the twins in different placental types.

Results: Dichorionic-separate, but not dichorionic-fused twins, are heavier than monochorionic-diamniotic and monoamniotic twins (2376±721 vs...

The association between maternal characteristics and different types and levels of discordance in triplet pregnancies

Objective: This study evaluated the association of maternal factors known to influence outcomes of triplets, different discordance levels (<25, 25.1–35, and >35%), and three types (according to the birth weight of the middle-sized triplet) of birth weight discordance in triplets.

Methods: We used data collected by the Women's Health Division of Matria Healthcare, Inc...
