Insights
Infant and perinatal mortality rates declined significantly in the 1980s, especially for low birth weight infants. However, mortality rates for newborns weighing 601-2500g remain high compared to developed nations.
Area of Science:
- Perinatal and infant health research
- Demographic trends in public health
- Neonatal mortality analysis
Context:
- Analysis of mortality dynamics during the 1980s.
- Focus on birthweight-specific infant and perinatal mortality.
- Comparison of mortality rates across different birth weight categories.
Purpose:
- To present the dynamics of birthweight-specific infant and perinatal mortality rates by age and cause during the 1980s.
- To identify trends and significant changes in mortality rates.
- To compare these rates with international standards.
Summary:
- The strongest decline in birthweight-specific infant and perinatal mortality rates was observed in newborns weighing less than 2500g.
- Despite a decrease, infant and perinatal mortality rates for newborns weighing 1001-2500g (100.5 and 109.4 in 1989) and 601-1000g (865.3 and 851.1 in 1989) remain high.
- Low birth weight prevalence was 7.9% in 1989.
Impact:
- Highlights the persistent challenge of high mortality rates in specific low birth weight groups.
- Provides data for targeted public health interventions for neonatal care.
- Informs policy decisions aimed at reducing infant and perinatal mortality in vulnerable populations.
Abstract:
The dynamics of the changes in the level of the birthweight-specific infant mortality and perinatal mortality rates by age and cause during the eighties is presented. The strongest decline in the birthweight-specific infant and perinatal mortality rates is observed among the newborns weighing less than 2500 g. The level of the low birth weight (7.9% in 1989) and despite the decrease--the infant and perinatal mortality rates among the newborns weighing 1001-2500 g (100.5 and 109.4 respectively in 1989) and among the newborns weighing 601-1000 g (865.3 and 851.1 respectively in 1989) are high comparing to the developed countries.
