Insights
Pediatric COVID-19 mortality rates vary significantly worldwide, correlating strongly with historical neonatal mortality. This highlights the impact of health system quality and social determinants on child COVID-19 outcomes.
Area of Science:
- Global Health
- Epidemiology
- Pediatrics
Background:
- Severe coronavirus disease 2019 (COVID-19) is rare in children, with a mortality rate around 0.08%.
- International disparities in pediatric COVID-19 mortality require investigation.
Purpose of the Study:
- To explore international variations in pediatric COVID-19 mortality rates.
- To identify factors associated with these disparities.
Main Methods:
- Analysis of COVID-19 deaths by age group in 23 countries with populations over 5 million.
- Data sourced from national health ministries, WHO, and COVID-19 databases.
Main Results:
- Pediatric mortality ranged from 0 to 12.1 deaths per million, with Peru having the highest rate.
- Pediatric COVID-19 mortality strongly correlated with 2018 neonatal mortality rates (r=0.77-0.88).
- Pediatric mortality showed a weaker correlation with general COVID-19 mortality (r=0.19-0.47).
Conclusions:
- International differences in pediatric COVID-19 mortality parallel historical neonatal mortality trends.
- Neonatal mortality reflects health system quality, suggesting social determinants influence child COVID-19 outcomes.
- Further research into social determinants of health is crucial for understanding pediatric mortality disparities.
Background:
Severe coronavirus disease 2019 (COVID-19) is infrequent in children and shows a mortality rate of around 0.08%. This study aims to explore international differences in the pediatric mortality rate.
Methods:
We analyzed several countries with populations over 5 million that report disaggregated data of COVID-19 deaths by quinquennial or decennial age groups. Data were extracted from COVID-19 cases and deaths by age database, National Ministeries of Health, and the World Health Organization.
Results:
We included 23 countries in the analysis. Pediatric mortality varied from 0 to 12.1 deaths per million children of the corresponding age group, with the highest rate in Peru. In most countries, deaths were more frequent in the 0-4-year-old age group, except for Brazil. The pediatric/general COVID-19 mortality showed a great variation and ranged from 0% (Republic of Korea) to 10.4% (India). Pediatric and pediatric/general COVID mortality correlates strongly with 2018 neonatal mortality (r = 0.77, p < 0.001; and r = 0.88, p < 0.001, respectively), while shows a moderate or no correlation (r = 0.47, p = 0.02; and r = 0.19, p = 0.38, respectively) with COVID-19 mortality in the general population.
Conclusions:
International heterogeneity in pediatric COVID-19 mortality importantly parallels historical neonatal mortality. Neonatal mortality is a well-known index of the quality of a country's health system, which points to the importance of social determinants of health in pediatric COVID-19 mortality disparities. This issue should be further explored.
