Perinatal mortality and one-year infant morbidity
Insights
Perinatal mortality significantly decreased due to fewer stillbirths and early neonatal deaths. Congenital abnormalities, not prematurity, were the primary cause of major infant handicaps.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Medicine
- Public Health
Background:
- Examining trends in perinatal mortality rates within a specific UK health district.
- Investigating the contributing factors to observed changes in stillbirth and neonatal death rates.
Observation:
- A notable decline in perinatal mortality from 20.8 to 11.3 per 1000 births between 1970 and 1976.
- Identifying the primary drivers of this reduction as decreased stillbirth rates and, more recently, lower early neonatal death rates.
Findings:
- A one-year follow-up of infants born in 1975 with perinatal issues revealed 12 major handicaps.
- Eight of these handicaps originated from prenatal issues, two from preterm delivery complications, and two from other perinatal conditions.
- Congenital abnormalities accounted for two-thirds of major handicaps, indicating they were the predominant cause.
Implications:
- The findings suggest that interventions targeting congenital abnormalities may be more impactful in reducing major infant handicaps than those solely focused on preterm delivery or low birth weight.
- Public health strategies should consider a comprehensive approach addressing prenatal factors to further improve infant outcomes.
- Continued monitoring of perinatal mortality and handicap causes is essential for refining healthcare interventions.
Abstract:
Perinatal mortality in Southampton and South-west Hampshire Health District fell from 20.8 per 1000 total births in 1970 to 11.3 per 1000 in 1976. This was atributable mainly to a fall in the stillbirth rate, but also to a recent fall in the neonatal death rate in the first week. All infants born in 1975 who had any problems in the perinatal period were followed up for one year. Of the 12 children identified at one year as having a major handicap, eight suffered from problems of prenatal origin, two from problems associated with preterm delivery, and two from other conditions acquired during the perinatal period. As two-thirds of the major handicaps arose from congenital abnormalities, preterm delivery and low birth weight were not the main causes of major handicap.
