Rachel A. Whitmer is an epidemiologist at the University of California, Davis. [1] Whitmer is a professor in the UC Davis Department of Public Health Sciences and chief of the UC Davis Division of Epidemiology. [2] She also works with Kaiser Permanente. [3] Whitmer received her undergraduate degree from the University of Massachusetts Amherst, and her PhD from UC Davis. [4]
Whitmer's research centers on the differing effects of dementia upon racial groups and age cohorts. [2] [5] Whitmer's findings have included a correlation between a woman's reproductive history and her chance of developing dementia. [5] [6] Another study led by Whitmer suggested a correlation between racism-related stress in African-American women and a higher risk of developing dementia. [7] [8] She is a primary investigator in the ongoing U.S. POINTER trial study of Alzheimer's led by the Alzheimer's Association. [9] [10]
Dementia is the general name for a decline in cognitive abilities that impacts a person's ability to perform everyday activities. This typically involves problems with memory, thinking, and behavior. Aside from memory impairment and a disruption in thought patterns, the most common symptoms include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia ultimately has a significant effect on the individual, caregivers, and on social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than what is caused by normal aging.
Triple oppression, also called double jeopardy, Jane Crow, or triple exploitation, is a theory developed by black socialists in the United States, such as Claudia Jones. The theory states that a connection exists between various types of oppression, specifically classism, racism, and sexism. It hypothesizes that all three types of oppression need to be overcome at once.
Diseases of affluence, previously called diseases of rich people, is a term sometimes given to selected diseases and other health conditions which are commonly thought to be a result of increasing wealth in a society. Also referred to as the "Western disease" paradigm, these diseases are in contrast to so-called "diseases of poverty", which largely result from and contribute to human impoverishment. These diseases of affluence have vastly increased in prevalence since the end of World War II.
Internalized racism is a form of internalized oppression, defined by sociologist Karen D. Pyke as the "internalization of racial oppression by the racially subordinated." In her study The Psychology of Racism, Robin Nicole Johnson emphasizes that internalized racism involves both "conscious and unconscious acceptance of a racial hierarchy in which whites are consistently ranked above people of color." These definitions encompass a wide range of instances, including, but not limited to, belief in negative stereotypes, adaptations to white cultural standards, and thinking that supports the status quo.
Race and health refers to how being identified with a specific race influences health. Race is a complex concept that has changed across chronological eras and depends on both self-identification and social recognition. In the study of race and health, scientists organize people in racial categories depending on different factors such as: phenotype, ancestry, social identity, genetic makeup and lived experience. "Race" and ethnicity often remain undifferentiated in health research.
Social epidemiology focuses on the patterns in morbidity and mortality rates that emerge as a result of social characteristics. While an individual's lifestyle choices or family history may place him or her at an increased risk for developing certain illnesses, there are social inequalities in health that cannot be explained by individual factors. Variations in health outcomes in the United States are attributed to several social characteristics, such as gender, race, socioeconomic status, the environment, and educational attainment. Inequalities in any or all of these social categories can contribute to health disparities, with some groups placed at an increased risk for acquiring chronic diseases than others.
Black women are women of sub-Saharan African and Afro-diasporic descent, as well as women of Australian Aboriginal and Melanesian descent. The term 'Black' is a racial classification of people, the definition of which has shifted over time and across cultures. As a result, the term 'Black women' describes a wide range of cultural identities with several meanings around the world.
Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens, and is the cause of 60–70% of cases of dementia. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation, mood swings, loss of motivation, self-neglect, and behavioral issues. As a person's condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the typical life expectancy following diagnosis is three to nine years.
Research shows many health disparities among different racial and ethnic groups in the United States. Different outcomes in mental and physical health exist between all U.S. Census-recognized racial groups, but these differences stem from different historical and current factors, including genetics, socioeconomic factors, and racism. Research has demonstrated that numerous health care professionals show implicit bias in the way that they treat patients. Certain diseases have a higher prevalence among specific racial groups, and life expectancy also varies across groups.
There are several classes of drugs for acid-related disorders, such as dyspepsia, peptic ulcer disease (PUD), gastroesophageal reflux disease (GORD/GERD), or laryngopharyngeal reflux.
The weathering hypothesis was proposed to account for early health deterioration as a result of cumulative exposure to experiences of social, economic and political adversity. It is well documented that minority groups and marginalized communities suffer from poorer health outcomes. This may be due to a multitude of stressors including prejudice, social alienation, institutional bias, political oppression, economic exclusion and racial discrimination. The weathering hypothesis proposes that the cumulative burden of these stressors as individuals age is "weathering," and the increased weathering experienced by minority groups compared to others can account for differences in health outcomes. In recent years, the biological plausibility of the weathering hypothesis has been investigated in studies evaluating the physiological effects of social, environmental and political stressors among marginalized communities. This has led to more widespread use of the weathering hypothesis as a framework for explaining health disparities on the basis of differential exposure to racially based stressors. Researchers have also identified patterns connecting weathering to biological phenomena associated with stress and aging, such as allostatic load, epigenetics, telomere shortening, and accelerated brain aging.
Chandra L. Ford is an American public health academic who is Professor of Community Health Sciences at the University of California, Los Angeles. She serves as Founding Director at the Center for the Study of Racism, Social Justice & Health. Her research considers relationships between racism and health outcomes.
Rachel Renee Hardeman is an American public health academic who is associate professor of Division of Health Policy and Management at the University of Minnesota School of Public Health. She holds the inaugural Blue Cross Endowed Professorship in Health and Racial Equity. Her research considers how racism impacts health outcomes, particularly for the maternal health of African-Americans.
Black maternal mortality in the United States refers to the death of women, specifically those who identify as Black or African American, during or after child delivery. In general, maternal death can be due to a myriad of factors, such as how the nature of the pregnancy or the delivery itself, but is not associated with unintentional or secondary causes. In the United States, around 700 women die from pregnancy-related illnesses or complications per year. This number does not include the approximately 50,000 women who experience life-threatening complications during childbirth, resulting in lifelong disabilities and complications. However, there are stark differences in maternal mortality rates for Black American women versus Indigenous American, Alaska Native, and White American women.
The COVID-19 pandemic has revealed race-based health care disparities in many countries, including the United States, United Kingdom, Norway, Sweden, Canada, and Singapore. These disparities are believed to originate from structural racism in these countries which pre-dates the pandemic; a commentary in The BMJ noted that "ethnoracialised differences in health outcomes have become the new normal across the world" as a result of ethnic and racial disparities in COVID-19 healthcare, determined by social factors. Data from the United States and elsewhere shows that minorities, especially black people, have been infected and killed at a disproportionate rate to white people.
Sirry Alang is a Cameroonian-American Health Services Researcher. She is an Associate Professor of Sociology and Health, Medicine and Society at Lehigh University. Alang is also a Medical Sociologist. Her research examines the structural causes of health inequity and the social determinants of health.
Jennifer J. Manly is an American neuropsychologist. She is a Professor of Neuropsychology in Neurology at the Gertrude H. Sergievsky Center and the Taub Institute for Research in Aging and Alzheimer's Disease at Columbia University. Manly studies how race, culture, socioeconomic status, and education influence the risk of cognitive decline in aging.
The COVID-19 pandemic has had an unequal impact on different racial and ethnic groups in the United States, resulting in new disparities of health outcomes as well as exacerbating existing health and economic disparities.

Alzheimer's disease (AD) in African Americans is becoming a rising topic of interest in AD care, support, and scientific research, as African Americans are disproportionately affected by AD. Recent research on AD has shown that there are clear disparities in the disease among racial groups, with higher prevalence and incidence in African Americans than the overall average. Pathologies for Alzheimer’s also seem to manifest differently in African Americans, including with neuroinflammation markers, cognitive decline, and biomarkers. Although there are genetic risk factors for Alzheimer’s, these account for few cases in all racial groups.
