Reducing black neonatal mortality. Will improvement in birth weight be enough?
JAMA
|January 18, 1985
Summary
Black neonates have lower mortality rates at lower birth weights, but higher rates of low birth weight negate this advantage. Improving birth weight distribution and reducing mortality in normal birth weight ranges are crucial for reducing black neonatal mortality.
Area of Science:
- Neonatal Health
- Perinatal Epidemiology
- Public Health Disparities
Background:
- Black neonatal mortality rates in the US are disproportionately high.
- Existing research indicates complex factors contribute to this disparity.
Purpose of the Study:
- To investigate factors influencing higher black neonatal mortality rates.
- To compare neonatal mortality risks between black and white neonates across birth weight and gestational age.
Main Methods:
- Utilized matched cohort records from California (1980-1981) and Georgia (1979-1981).
- Analyzed neonatal mortality rates stratified by birth weight and gestational age for black and white infants.
Main Results:
- Black neonates under 3,000g had lower mortality rates than white neonates at similar birth weights and gestational ages.
- Higher rates of low birth weight among black neonates offset their survival advantage.
- White neonates had a survival advantage for birth weights of 3,000g or more; black neonates had nearly double the mortality rate even at optimal birth weights.
Conclusions:
- Reducing black neonatal mortality requires improvements in both birth weight distribution and birth-weight-specific mortality rates.
- Particular focus is needed on improving survival rates within normal birth weight ranges for black neonates.
