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 ...

It has been well established that increased maternal education, income, and social status contribute to increased birth weight, as well as reduced risk for low or very low birth weight offspring. 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...

CONTEXT The extent to which young women's risk of adolescent pregnancy is associated with having a mother who was a teenage parent, a sister who was a teenage parent or both is not known. METHODS A sample of 127 Latina and black adolescent females completed in-depth surveys at three time points between 1994 and 2000. Logistic regression analyses were used to examine whether socioeconomic fact...

background: preterm birth (ptb) is responsible for 70% of neonatal mortalities. various factors influence the risk of neonatal mortality in different populations. objective: our objective was to evaluate neonatal survival rate of preterm infants, and to define its predictors in iranian population. materials and methods: this retrospective cohort study included all preterm (26-37 weeks) infants ...

a descriptive prospective study was undertaken to determine birth weight, length and head circumference of live births and to examine the effect of maternal age, parity and gestational age on birth sizes of the live births. a total of 459 term singleton maternal– neonate pairs were studied. the neonates had anthropometric measurements determined with in 24hours of life using standard methods. t...

Although outcomes of neonatal cardiac surgery have dramatically improved in the last two decades, low body weight still constitutes an important risk factor for morbidity and mortality. In particular, cardiac surgery in neonates with very low birth weight (≤1.5 kg) is carried out with greater risk because most organ systems are immature. We report here on a successful case of early one-stage to...
