[Trends in infant mortality in Barcelona [Spain], 1983-1998]
1Clinical Data Care Spain.
Insights
Infant mortality in Barcelona significantly declined between 1983 and 1998, with early neonatal deaths decreasing most notably. Congenital defects and perinatal causes remained the leading causes of infant death.
Area of Science:
- Pediatrics
- Public Health
- Demography
Context:
- Infant mortality trends are crucial indicators of a population's health status.
- Understanding the components and causes of infant mortality is vital for targeted public health interventions.
- Barcelona, Spain, provides a specific urban demographic for analyzing these trends.
Purpose:
- To analyze infant mortality trends in Barcelona from 1983 to 1998.
- To examine the main components of infant mortality, including neonatal and postneonatal periods.
- To identify the principal causes of infant death during the study period.
Summary:
- Infant mortality rates in Barcelona decreased from 10.5 in 1986 to 3.4 per 1,000 live births in 1996.
- Mortality rates stabilized between 1983-1988 before declining post-1989.
- Early neonatal mortality saw a more significant reduction than postneonatal mortality.
- Congenital defects (47.4%) and perinatal causes (32.1%) were the primary causes of death.
Impact:
- The study highlights a positive but decelerating trend in infant mortality reduction.
- Findings can inform public health strategies for reducing infant deaths, particularly those related to congenital and perinatal issues.
- This analysis provides valuable data for comparing urban infant mortality trends over time.
Objective:
To analyze trends in infant mortality, taking into account its main components and the principal causes of death between 1983 and 1998 in the city of Barcelona (Spain).
Methods:
We calculated overall mortality rates and mortality rates by sex for infant, postneonatal, neonatal, early neonatal, and late neonatal mortality in residents of the city of Barcelona from 1983 to 1998. Data were obtained from the births and deaths register. Data were grouped in 4-year periods. Poisson regression models were adjusted to obtain relative risks of mortality for comparison among the 4-year periods. The percentage of variation between rates in the different periods was also calculated.
Results:
There were 1.564 deaths in the 16 years. 896 (57.3%) were males and 668 (42.7%) were females. Infant mortality rates varied from 10.5 per 1,000 live births in 1986 to 3.4 ten years later (1996). Between 1983 and 1988 mortality rates remained stable, decreasing after 1989. The neonatal mortality rate, and especially the early neonatal mortality rate, showed a greater decrease than the postneonatal mortality rate. The main causes of death were congenital defects (47.4%) and perinatal causes (32.1%).
Conclusions:
Mortality rates decreased over the study period but not with the same intensity as in previous deca des.
