OBJECTIVE To explore the relationship between low and very low birth weights, mother's age, individual socioeconomic status and area deprivation. DESIGN Analysis of the incidence of low and very low birth weights by area deprivation, maternal age, social class of household and estimated income. SETTING England 1996-2000. SUBJECTS 2 894 440 singleton live births and the 10% sample of these...

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 ...

However, there remains controversy about the mechanism(s) for this effect, as well as the interactions between these factors, maternal age, and race. Presented here is the analysis of a large, recent s...

BACKGROUND Information on birth outcome among the Asian and Pacific Islander populations in the US is limited. This report examines the risks of moderately low (MLBW) and very low birthweight (VLBW) among six Asian subgroups (Chinese, Japanese, Fillipinos, Asian Indians, Koreans, Vietnamese) and three Pacific Islander subgroups (Hawaiians, Guamanians, Samoans) as compared with non-Hispanic whit...
