Understanding the disparities in mortality rates between racial groups in the United States is essential for addressing public health challenges. Since 1999, the gap in mortality rates between the Black and White populations has shown significant fluctuations, with periods of both decrease and increase. This article aims to identify the specific causes of death associated with these disparities and their evolution over time, using data from the US Centers for Disease Control and Prevention (CDC) and other sources.
Understanding Mortality Disparities
Mortality disparities between racial groups reflect broader social inequities. In the US, the Black community has historically experienced higher mortality rates compared to the White population. These disparities are influenced by factors such as socioeconomic status, access to healthcare, and systemic discrimination.
To understand these disparities, researchers have focused on all-cause mortality rates, which provide a comprehensive overview of death rates from all causes within a population. Analysing trends in these rates helps identify areas where progress has been made and where continued efforts are needed.
Methods for Analysing Mortality Trends
The analysis of mortality trends in the Black community involved using data from the CDC’s Wide-Ranging Online Data for Epidemiologic Research (WONDER) database. Age-adjusted mortality rates (AAMRs) were collected for both Black and White populations from 1999 to 2020, stratified by sex. This approach allows for a comparison of mortality rates while accounting for differences in age distribution between the populations.
The study also focused on the 15 primary underlying causes of death, resulting in 18 unique causes. For 2020, COVID-19 was included as an additional cause of death. By calculating the excess AAMR, researchers could determine the difference in mortality rates between the Black and White populations, highlighting which causes contributed most significantly to the disparities.
Key Findings from the Data
Reductions in Mortality Rates
From 1999 to 2020, there were notable reductions in excess mortality rates among the Black population. The mean excess AAMR per 100,000 individuals decreased steadily for both Black females and males. For females, the annual mean reduction was 5.7%, while for males, it was 5.2%.
Among Black males, reductions in mortality rates were primarily due to decreases in deaths from cancer, heart disease, accidents, and HIV. Similarly, Black females experienced significant reductions in deaths from heart disease, diabetes, cancer, accidents, and cerebrovascular diseases.
Reversals in Progress
Despite progress in reducing mortality rates, recent years have seen reversals in some areas. From 2012 to 2019, there were increases in excess mortality rates for Black males due to accidents, heart disease, cerebrovascular disease, and assault. For Black females, similar increases occurred from 2016 to 2019.
In 2020, the COVID-19 pandemic exacerbated these disparities, leading to marked increases in excess mortality rates for both Black males and females. COVID-19 accounted for a significant portion of the increase, underscoring the pandemic’s disproportionate impact on vulnerable communities.
Discussion on Mortality Trends
The progress in reducing mortality rates among the Black community is a testament to the effectiveness of public health interventions in certain areas, particularly in addressing major causes of death like cancer and cardiovascular diseases. However, the resurgence of mortality rates from external causes, such as assaults and accidents, highlights the need for continued vigilance and targeted interventions.
The Role of Structural Factors
It is essential to recognise that race is a social construct, and structural social factors play a significant role in shaping mortality disparities. Socioeconomic conditions, access to healthcare, and systemic discrimination all contribute to the observed disparities. Addressing these factors is crucial for achieving lasting improvements in mortality rates.
Implications for Public Health
Public health efforts should focus on regaining the progress made in reducing mortality rates and addressing the root causes of disparities. Evidence-based interventions are needed to promote health equity and improve outcomes for the Black community. This includes initiatives to improve access to healthcare, reduce systemic discrimination, and address socioeconomic determinants of health.
Limitations of the Study
While this analysis provides valuable insights into mortality trends, it is important to acknowledge its limitations. The use of death certificate data may introduce misclassification biases, as inaccuracies in reporting cause of death and demographic characteristics can occur. Additionally, there are variations in outcomes within the Black community, such as differences between US-born and non-US-born individuals, as well as geographic variability in mortality trends.
Moving Forward
To effectively address mortality disparities, a multifaceted approach is required. Efforts should include:
- Health Equity Initiatives: Focus on reducing systemic barriers to healthcare access and addressing social determinants of health.
- Community Engagement: Collaborate with community leaders and organisations to develop culturally tailored interventions that address the unique needs of the Black community.
- Policy Changes: Advocate for policies that promote health equity and reduce systemic discrimination.
- Research and Data Collection: Continue to collect and analyse data to monitor trends and identify emerging disparities.
Advancing Health Equity in the Black Community
Understanding mortality trends within the Black community is crucial for achieving health equity. While progress has been made in reducing certain causes of death, recent setbacks underscore the ongoing challenges faced by this community. By addressing structural factors, such as discrimination and poverty, implementing evidence-based interventions, and fostering community engagement, we can work towards a future where everyone has the opportunity to lead a healthy life. Closing the gap in mortality rates between racial groups necessitates a focus on improving healthcare access and tackling these systemic issues, ultimately creating healthier, more equitable communities for all.
