OBJECTIVE We investigated the association between high parity and fetal morbidity outcomes. METHODS We analyzed 22,463,141 singleton deliveries at 20 weeks or more of gestation in the United States from 1989 through 2000. Adjusted odds ratios generated from logistic regression models were used to approximate relative risk for neonatal morbidity in women with 1-4 (moderate parity or type I; re...

AIM To compare children of very low birth weight with matched controls for their performance in the General Certificate of Secondary Education (GCSE). METHODS GCSE examination results of 167 children of birth weight < or =1500 g attending mainstream schools and without clinical disability and 167 individually matched classroom controls were analysed. RESULTS In 143 instances, both children ...

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 ...

A reference table of weight-for-height by week of pregnancy has been devised on theoretical grounds, based on the premises that the average increment of weight during pregnancy is 20% of the prepregnant weight and that almost all the increment takes place linearly during the 2nd and 3rd trimesters of pregnancy. The table was tested with retrospective clinic and hospital data. The results show a...

BACKGROUND The purpose was, first, to evaluate changes in health-related quality of life (HRQL) in a cohort of very low birth weight (VLBW; <1500 g.) or very preterm (< 32 weeks of gestation) children between ages 14 and 19, and second, to identify correlates of HRQL at age 19. METHODS HRQL was assessed using the Health Utilities Index Mark 3 (HUI3). In order to explore correlates of HRQL, we...
