MMWR. Morbidity and Mortality Weekly Report
|February 15, 1991
Insights
Birth defect rates in newborns are linked to infant birth weight. This study examined the relationship between birth defects and birth weight in Atlanta infants from 1978-1988.
Area of Science:
- Pediatric Health
- Public Health
- Epidemiology
Background:
- Major birth defects affect 3%-4% of newborns within the first year.
- Prematurity and intrauterine growth retardation are common in infants with birth defects.
- Birth weight is a potential factor influencing birth defect rates.
Purpose of the Study:
- To investigate the association between birth defect occurrence and infant birth weight.
- To analyze population-based data on birth defects and birth weight.
Main Methods:
- Population-based study design.
- Data collected from infants born in metropolitan Atlanta.
- Analysis of birth defect diagnoses and birth weight records from 1978-1988.
Main Results:
- The study analyzed the relationship between birth defect rates and birth weight.
- Findings are expected to show variations in birth defect rates based on birth weight categories.
Conclusions:
- Understanding the link between birth weight and birth defects is crucial for public health.
- This research provides insights into birth defect epidemiology related to gestational factors.
Abstract:
Approximately 3%-4% of newborn infants have a major birth defect diagnosed during their first year of life. Because many infants with birth defects are born prematurely and/or have intrauterine growth retardation, the rate of birth defects is expected to vary by birth weight. This report summarizes a population-based study of the relation between birth defect rates and the birth weight of infants born in metropolitan Atlanta from 1978 through 1988.
