In a prospective study of 3,857 pregnancies ending in singleton live births at Yale-New Haven Hospital, New Haven, Connecticut, in 1980-1982, 9.5% of mothers reported using marijuana (4.1% occasionally and 5.4% at least 2-3 times monthly). Among white women, regular use was associated with an increased risk of delivering a low birth weight (less than 2,500 gm) infant (odds ratio (OR) = 2.6, 95%...

As part of a longitudinal developmental study of newborn and young Dutch twins, data on weight and height are collected. Birth weight and height are available for 3275 pairs; data on growth, for 1390 pairs.

This paper examines the determinants of hospitalized very low birth weight infant (or neonatal) mortality using the Taiwan National Health Insurance Research database from 1997 to 2009. After infants are discharged from hospital, it is not possible to track their mortality, so the Cox proportional hazard model is used to analyze the very low birth weight infant mortality rate. In order to clari...

Retinopathy of prematurity (ROP) is a multifactorial vasoproliferative retinal disorder that increases in incidence with decreasing gestational age. Recently, an association between hyperglycemia and severe ROP was found in extremely low birth weight infants (ELBWI). The purpose of this study was to evaluate the possible relation between hyperglycemia and ROP at any stage in very low birth weig...

conclusions: the increased survival of preterm infants was not associated with lower complications. there is now increasing evidence of sustained adverse outcomes into school age and adolescence, for preterm infants. results: cerebral palsy especially spastic diplegia, intellectual disability, visual (retinopathy of prematurity) and hearing impairments are the main neurodevelopmental disorders ...

Genetic and environmental inputs may shape population health disparities in varying ways. In this article, we use unique variation involved in twin births to attempt to untangle how genetic and prenatal environmental variation may make different contributions to infant health among white and black populations in the United States. Using twin fixed effects models and data from the 1995-1997 Matc...

BACKGROUND: Low birth weight (<2,500 g) is a strong predictor of infant mortality. Yet low birth weight, in isolation, is uninformative since it is comprised of two intertwined components: preterm delivery and reduced fetal growth. Through nonparametric logistic regression models, we examine the effects of gestational age, fetal growth, and maternal smoking on neonatal mortality. METHODS: We de...

AIMS To compare the survival and sensorineural disability rates in extremely low birthweight (ELBW) (500-999 g) infants born in 1991-2 with ELBW babies born in 1979-80 and 1985-7, and with normal birthweight infants born in the same time periods. METHODS ELBW infants born in Victoria in 1991-2 were compared with regional cohorts of ELBW infants born in 1979-80 and 1985-7, and with contemporan...
