The risk of low birthweight
American Journal of Public Health
|September 1, 1979
Summary
Several factors, including race not white, previous reproductive loss, and lack of prenatal care, increase the risk of low birthweight infants. Maternal age extremes also contribute to this risk.
Area of Science:
- Perinatal Epidemiology
- Maternal and Child Health
Background:
- Low birthweight is a significant concern in infant health.
- Understanding risk factors is crucial for targeted interventions.
Purpose of the Study:
- To identify demographic and reproductive correlates of low birthweight in the United States.
- To quantify the risk associated with various maternal and infant factors.
Main Methods:
- Descriptive and multivariate analyses of 1974 US birth certificate data.
- Examination of factors including race, reproductive history, interpregnancy interval, and maternal age.
Main Results:
- Non-white race, prior reproductive loss, short interpregnancy interval, out-of-wedlock birth, and no prenatal care were associated with increased low birthweight risk.
- Maternal age under 18 or over 35 years also increased risk.
- High birth order and maternal education <12 years were not consistent risk factors.
Conclusions:
- Identified key risk factors for low birthweight infants in 1974.
- Findings highlight the importance of prenatal care and appropriate interpregnancy intervals.
- Provides a method to estimate individual risk for low birthweight.
