Leading Causes of Death Contributing to Decrease in Life Expectancy Gap Between Black and White Populations: United...

Area of Science:

• Public Health
• Epidemiology
• Demography

Background:

• Life expectancy at birth in the U.S. has risen significantly since 1900.
• Persistent disparities in life expectancy exist between White and Black populations.
• The gap in life expectancy between these groups narrowed between 1999 and 2013.

Purpose of the Study:

• To analyze the changes in leading causes of death contributing to the narrowing life expectancy gap.
• To identify specific causes of death that reduced the disparity between White and Black populations.
• To examine causes of death that widened the gap, particularly for Black males and females.

Main Methods:

• Analysis of mortality data from 1999 to 2013.
• Comparison of changes in death rates for leading causes of death between White and Black populations.
• Calculation of the impact of specific causes of death on the life expectancy gap.

Main Results:

• The life expectancy gap decreased from 5.9 years in 1999 to 3.6 years in 2013.
• Greater reductions in mortality from heart disease, cancer, HIV disease, unintentional injuries, and perinatal conditions among Black individuals were key drivers.
• Increases in death rates for aortic aneurysm, Alzheimer's disease, and maternal conditions in the Black population limited a larger reduction in the gap.

Conclusions:

• Changes in mortality patterns for specific diseases significantly influenced the narrowing life expectancy gap.
• Targeted public health interventions addressing leading causes of death are crucial for further reducing racial disparities.
• Understanding the differential impact of diseases is essential for improving population health outcomes.
