In this paper, a cohort of 297 twin pregnancies was iden-tified from a single practice with measured prepregnancy body mass index (BMI) and weight gain during preg-nancy.Abstract:
OBJECTIVE: To estimate whether the weight gain rec-ommendations for twin pregnancies in the 2009 Instituteof Medicine (IOM) guidelines are associated with im-proved perinatal outcomes.METHODS: A cohort of 297 twin pregnancies was iden-tified from a single practice with measured prepregnancybody mass index (BMI) and weight gain during preg-nancy. Recommended IOM guidelines were applied toour cohort based on prepregnancy BMI categories (nor-mal weight, overweight, obese). Pregnancy outcomeswere compared between patients whose weight gain metor exceeded the IOM recommendations and patientswho did not meet these recommendations.RESULTS: Patients with normal prepregnancy BMIswhose weight gain met the IOM recommendations hadsignificantly improved outcomes compared with patientswho did not meet the IOM recommendations. They wereless likely to have preterm birth before 32 weeks (5.0%compared with 13.8%) and spontaneous preterm birthbefore 32 weeks (3.4% compared with 11.5%). They alsodelivered significantly larger neontates (larger twin birthweight 2,582.1read more

Excessive weight gain in term twin pregnancies: examining the 2009 Institute of Medicine definitions.
TL;DR: Excessive weight gain in term twin gestations, as defined by the IOM, does not appear to be associated with worse maternal outcomes and is associated with larger birth weights, which calls into question the 2009 IOM definition of excessive weight gain.

Gestational weight gain in twin pregnancies and maternal and child health: a systematic review
TL;DR: A systematic review of data interrogating the association between gestational weight gain (GWG) and maternal and child health among women with twin gestations underscores that GWG in twingestations is a neglected area of research.

TL;DR: Additional screening and iron supplementation may be warranted in this high-risk population of healthy women with multiple gestations given the known associations between ID anemia and adverse maternal and neonatal outcomes.

TL;DR: It is confirmed that weekly maternal weight gain according to the IOM guidelines results in improved outcomes in twin pregnancies, including higher mean gestational age at delivery, higher birth weight infants and less prematurity.

TL;DR: It is important to consider enrolling multifetal pregnancies in studies that mainly target women with singletons, even when sample size is inadequate, so that insights specific to multiples can be obtained when results of smaller studies are pooled together.

Births: final data for 2005.
TL;DR: The cesarean delivery rate climbed to more than 30 percent of all births, another all-time high; the twin birth rate was unchanged and the rate of triplet and higher order multiple births declined for the 7th consecutive year.

A nearly continuous measure of birth weight for gestational age using a United States national reference
TL;DR: Birth weight rose with greater gestational age, with increasing slopes during the third trimester and a leveling off beyond 40 weeks, which should prove useful for researchers investigating the predictors and outcomes of altered fetal growth.

TL;DR: The cesarean delivery rate jumped 6 percent to another all-time high, whereas the rate of vaginal birth after previous cesAREan fell by 13 percent, and preterm and low birthweight rates continued their steady rise.

TL;DR: 2005 period infant mortality statistics from the linked birth/infant death data file are presented by a variety of maternal and infant characteristics, which differs from the mortality file, which is based entirely on death certificate data.

Nutrition during pregnancy : part I, weight gain : part II, nutrient supplements
TL;DR: Relationships between weight gain during pregnancy and a variety of factors are explored and the adequacy of diet in meeting nutrient needs during pregnancy is examined, as well as the effects of caffeine, alcohol, cigarette, marijuana, and cocaine use.
