Insights
Infant deaths from intracranial hemorrhage (ICH) have declined significantly since 2003. However, disparities persist among different demographic groups, highlighting the need for equitable infant care.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Background:
- Intracranial hemorrhage (ICH) is a significant cause of infant mortality and neurodevelopmental issues.
- National trends and demographic disparities in infant ICH mortality are not well understood.
Purpose of the Study:
- To analyze national mortality trends and demographic disparities in infant intracranial hemorrhage (ICH).
Main Methods:
- Retrospective analysis of the CDC WONDER Multiple Cause of Death database (1999-2020).
- Identified infant deaths with ICH (ICD-10 P52) as a cause.
- Calculated mortality rates and used Joinpoint regression to assess trends.
Main Results:
- 20,544 infant ICH deaths recorded from 1999-2020.
- Overall mortality rate declined from 31.57 (2003) to 17.32 (2020) per 100,000 live births (AAPC -2.51%).
- Disparities observed in mortality rates by sex, race (highest in Non-Hispanic Blacks), region (highest in Southern states), and urbanization.
Conclusions:
- Infant ICH mortality has substantially decreased nationwide.
- Persistent disparities by sex, race, region, and urbanization necessitate equitable maternal and infant healthcare.
Background:
Intracranial hemorrhage (ICH) is a major cause of infant mortality and neurodevelopmental complications, yet national mortality trends and demographic disparities remain poorly characterized.
Methods:
A retrospective analysis using the CDC WONDER Multiple Cause of Death database (1999-2020) identified infant (<1 year) deaths with ICH (ICD-10 P52) as an underlying or contributing cause. Mortality rates per 100,000 live births were calculated by demographic and geographic factors, and Joinpoint regression estimated annual and average annual percent changes (APC, AAPC) with 95% confidence intervals.
Results:
From 1999 to 2020, 20,544 infant ICH deaths were recorded in the United States, with a crude rate of 23.64 per 100,000 live births. Mortality peaked in 2003 at 31.57 and declined to 17.32 by 2020 (AAPC -2.51%). Among 20,544 ICH infant deaths recorded , mortality declined from 31.57 (2003) to 17.32 (2020) (AAPC -2.51%). Males exceeded females (28.18 vs. 18.88), Non-Hispanic Blacks had the highest racial rate (37.5), and Southern states showed the greatest regional burden. Urban areas declined faster than rural (AAPC -2.53% vs. -1.89%).
Conclusions:
Despite substantial overall decline in infant ICH rates, persistent disparities by sex, race, region, and urbanization underscore the need for equitable maternal and infant healthcare.
