Hess (1934) in an extensive and careful study of the development of prematurely-born children (which he defines as weighing five and a half pounds or less at birth, irrespective of the duration of gestation) compares the weight of prematurely-born children at various age periods with that of their full-term siblings, and comes to the conclusion that the former consistently weigh less than the l...

OBJECTIVE The objective of this study was to estimate national hospital costs for infant admissions that are associated with preterm birth/low birth weight. METHODS Infant (<1 year) hospital discharge data, including delivery, transfers, and readmissions, were analyzed by using the 2001 Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project. The Nationwide Inpatient Samp...

Advanced maternal age at birth is considered a major risk factor for birth outcomes. It is unclear to what extent this association is confounded by maternal characteristics. To test whether advanced maternal age at birth independently increases the risk of low birth weight (<2,500 g) and preterm birth (<37 weeks' gestation), we compared between-family models (children born to different mothers ...

OBJECTIVE The present study is a literature review to identify the effects of a very low birth weight newborn on family. This is an important instrument to clarify epidemiological issues and to suggest the directions for health policy efforts. METHOD A three-step review was carried out using databases of journals indexed for Medline/Lilacs/ Scielo/Cochrane published between 1966 and 2005 usin...

Birth weight in triplets is, on average, lower than in singletons and twins, and more children are classified as having very low or extremely low birth weight. Still, there is limited research on factors that affect triplet birth weight, and samples under study are often small. Chorionicity and zygosity influence triplet birth weight, but it is unknown whether the effect of zygosity can be enti...

OBJECTIVE The aim of the present study was to compare the beginning of eruption of the first deciduous tooth in preterm infants (<38 weeks) with full-term infants (38 and 42 weeks) of normal birth weight ((3)2.500g), low birth weight (< 2.500g) and very low birth weight (<1.500g), in order to evaluate if premature birth and low birth weight would affect tooth eruption. METHODS The neonatal re...

OBJECTIVES To determine whether treatment of trichomoniasis increases the risk of prematurity. DESIGN Sub-analysis of a randomised trial. SETTING We analysed data from HPTN trial of antenatal and intrapartum antibiotics to reduce chorioamnionitis-related perinatal HIV transmission. SUBJECTS Pregnant women from four sites in Africa. OUTCOME MEASURES Gestational age at the time of deliver...

As there have been conflicting reports about intelligence in children of very low birth weight, advantage was taken of an opportunity to study the intelligence of 1,066 children weighing 4 lb. or less at birth who were the subjects of an investigation into the aetiology of cerebral palsy and other disorders* (McDonald, 1962, 1963). The many surveys of the intelligence of premature children were...

BACKGROUND The International Network for Evaluating Outcomes in Neonates (iNeo) is a collaboration of population-based national neonatal networks including Australia and New Zealand, Canada, Israel, Japan, Spain, Sweden, Switzerland, and the UK. The aim of iNeo is to provide a platform for comparative evaluation of outcomes of very preterm and very low birth weight neonates at the national, sit...
