Stroke Disparities: Key Databases on African-American Risk
This paper examines racial disparities in stroke incidence and mortality, focusing on the elevated risk faced by African-Americans compared to Whites. The author evaluates five major databases and online resources — the CDC, the Internet Stroke Center, the Stroke Belt website, the National Stroke Association, and the American Stroke Association — for their utility in researching stroke outcomes among African-Americans. Each database is assessed for the type of evidence it provides, its relevance to minority health disparities, and its potential use by clinicians and researchers. Together, these resources offer a broad foundation of epidemiological data, clinical guidelines, and patient education materials relevant to addressing stroke inequities.

What makes this paper effective
- Each database review follows a consistent structure — describing the source's purpose, content, and specific relevance to African-American stroke disparities — making the paper easy to navigate and compare across entries.
- The introduction grounds the paper with concrete statistics (e.g., the Framingham Stroke Risk Score accounting for 40% of racial differences) that justify the author's focus, lending credibility to the database selection.
- The author honestly acknowledges limitations, such as the Internet Stroke Center's predominance of foreign sources, while still explaining how the resource remains useful for benchmarking care quality.
Key academic technique demonstrated
The paper demonstrates annotated database evaluation — a research skill that goes beyond simply listing sources. Each entry describes not only what the resource contains but also how it can be applied to a specific research question (stroke disparities in African-Americans), modeling the kind of critical source appraisal expected in graduate-level health sciences work.
Structure breakdown
The paper opens with a brief literature-grounded introduction establishing the public health problem and rationale. It then proceeds through five database reviews of roughly equal length, each organized into two paragraphs: one describing the database's general content and one assessing its specific value for the topic. There is no separate conclusion section; instead, each database entry ends with a closing evaluative sentence that functions as a mini-conclusion for that source.
Introduction: Racial Disparities in Stroke
The incidence and mortality rates for stroke differ markedly along racial lines, with African-Americans having a much higher risk of stroke and death from stroke compared to Whites (Howard, 2013). Approximately 40% of this difference can be explained by the variables included within the Framingham Stroke Risk Score, while another 10% can be explained by socioeconomic status. Other contributing factors probably include differential health care access and quality.
Accordingly, the Surgeon General of the United States (2014) recently issued a statement describing government actions being taken to reduce health disparities and published a list of recommendations for providers. Among these recommendations are focusing on at-risk communities, improving care access and quality, improving provider training, and better evaluation of stroke risk among minorities. For these reasons, this paper focuses on stroke incidence and mortality in African-Americans.
CDC: Evidence-Based Data and Geographic Tools
The CDC maintains a significant amount of information about stroke on its website. The CDC is an agency within the Department of Health and Human Services dedicated to the prevention of morbidity and mortality due to disease, injury, or lifestyle choices. Among this massive collection of information — a substantial proportion of which is peer-reviewed and available through the Library of Medicine — is source material focused on stroke in the American population. This material includes evidence-based fact sheets, direct access to the CDC journal Morbidity and Mortality Weekly Report, online tools, white papers, and commissioned reports.
Although most of the fact sheets are focused on the general population, at least one provides information specific to the African-American demographic. The "Take Control of Your Heart: It's All in the ABCS" fact sheet provides general recommendations for minimizing stroke risk, but scattered within these recommendations are statistics concerning the African-American population. Among the online tools is an Interactive Atlas of Heart Disease and Stroke, which provides detailed geographic distributions of stroke outcomes by race, gender, and age. The statistical resources include the Behavioral Risk Factor Surveillance System (BRFSS) survey data, the Morbidity and Mortality Chartbook from the National Heart, Lung, and Blood Institute (NHLBI), and data from the American Heart Association. The Chartbook from the NHLBI, for example, presents the leading causes of death for African-Americans in 2008, stratified by gender; stroke is the 4th and 3rd leading cause of death for Black males and females, respectively. The CDC website is therefore a rich source of evidence-based recommendations, study findings, and statistics related to stroke among African-Americans.
Internet Stroke Center: Global Best-Practice Guidelines
The Internet Stroke Center is the product of a number of agencies and institutions, including the National Institutes of Health Specialized Programs of Translational Research in Acute Stroke (SPOTRIAS) Network, the National Institute of Neurological Disease and Stroke, and the University of Texas Southwestern Medical Center. The purpose of the site is to provide a centralized resource for researchers and clinicians interested in all aspects of stroke, where current best-practice recommendations can be found, along with meeting presentations, published accounts, correspondence between experts, and the Stroke Trials Registry. The main categories of guidelines available on this site include: (1) general stroke, (2) acute stroke management, (3) stroke prevention, (4) stroke recovery, (5) organizing stroke care, (6) diagnosis, (7) imaging, and (8) pediatric stroke.
The majority of the information provided in this database comes from foreign sources and therefore contains little to no information specifically about stroke in African-Americans; however, the website represents an exhaustive source of best-practice recommendations for stroke prevention and treatment from experts around the globe. This source material therefore represents standards against which the care being provided to African-Americans can be compared. There are also a number of guidelines and recommendations available from American sources. The National Stroke Association, for example, issued guidelines for the prevention of first stroke and notes that hypertension occurs in African-Americans more frequently, at an earlier age, and in a more severe form. The Internet Stroke Center can therefore serve as a portal and database for all things stroke, in addition to providing best-practice recommendations specific to the African-American population.
