Slavery Hypertension Hypothesis
The slavery hypertension hypothesis proposes that disproportionately high rates of hypertension among black people in the New World are due to selection bias preferring individuals who retain more sodium among black slaves during the Middle Passage. __TOC__ History It was originally proposed in 1983 by Clarence Grim and Thomas W. Wilson, who subsequently promoted it heavily during the remainder of the 1980s. It gained considerable media attention when Grim presented it at a conference in 1988. In 1990, the first medical textbook mentioning the hypothesis was published. The first peer-reviewed paper advancing the hypothesis was published by Wilson and Grim in 1991. This study also received considerable media attention. In December 2004, a paper titled ''CYP3A Variation and the Evolution of Salt-Sensitivity Variants'' was published which drew attention to the importance of the CPY3A5*1 and CPY3A5*3 alleles of cytochrome P450 CYP3A5 in hypertensive disease. The paper showed a substant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypertension
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide. High blood pressure is classified as primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use. The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such ...

The New Republic
''The New Republic'' is an American magazine of commentary on politics, contemporary culture, and the arts. Founded in 1914 by several leaders of the progressive movement, it attempted to find a balance between "a liberalism centered in humanitarian and moral passion and one based in an ethos of scientific analysis". Through the 1980s and 1990s, the magazine incorporated elements of the Third Way and conservatism. In 2014, two years after Facebook co-founder Chris Hughes purchased the magazine, he ousted its editor and attempted to remake its format, operations, and partisan stances, provoking the resignation of the majority of its editors and writers. In early 2016, Hughes announced he was putting the magazine up for sale, indicating the need for "new vision and leadership". The magazine was sold in February 2016 to Win McCormack, under whom the publication has returned to a more progressive stance. A weekly or near-weekly for most of its history, the magazine currently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypotheses
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought. A different meaning of the term ''hypothesis'' is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If ''P'', then ''Q''", ''P'' denotes the hypothesis (or antecedent); ''Q'' can be called a consequent. ''P'' is the assumption in a (possibly counterfactual) ''What If'' question. The adjective ''hypothetical'', meaning " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weathering Hypothesis
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 fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slave Health On Plantations In The United States
The health of slaves on American plantations was a matter of concern to both slaves and their owners. Slavery had associated with it the health problems commonly associated with poverty. It was to the economic advantage of owners to keep their working slaves healthy, and those of reproductive age reproducing. Those who could not work or reproduce because of illness or age were sometimes abandoned by their owners, expelled from plantations, and left to fend for themselves. Life expectancy A broad and common measure of the health of a population is its life expectancy. The life expectancy in 1850 of a white person in the United States was forty; for a slave, thirty-six. Mortality statistics for whites were calculated from census data; statistics for slaves were based on small sample-sizes. Diseases among slaves European physicians in the West Indies frequently shared their knowledge of black-related diseases with North American colleagues. Diseases that were thought to be "negro dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seasoning (slavery)
Seasoning, or The Seasoning, was the period of adjustment that slave traders and slaveholders subjected African slaves to following their arrival in the Americas. While modern scholarship has occasionally applied this term to the brief period of acclimatization undergone by European immigrants to the Americas, it most frequently and formally referred to the process undergone by enslaved people. Slave traders used "seasoning" in this colonial context to refer to the process of adjusting the enslaved Africans to the new climate, diet, geography, and ecology of the Americas. The term applied to both the physical acclimatization of the enslaved person to the environment and that person's adjustment to a new social environment, labor regimen, and language. Slave traders and owners believed that, if a person survived this critical period of environmental seasoning, they were less likely to die and the psychological element would make them more easily controlled. This process took place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minority Stress
Minority stress describes high levels of stress faced by members of stigmatized minority groups. It may be caused by a number of factors, including poor social support and low socioeconomic status; well understood causes of minority stress are interpersonal prejudice and discrimination. Indeed, numerous scientific studies have shown that when minority individuals experience a high degree of prejudice, this can cause stress responses (e.g., high blood pressure, anxiety) that accrue over time, eventually leading to poor mental and physical health.Meyer, I. H., & Northridge, M. E. (Eds.). (2007). ''The health of sexual minorities: Public health perspectives on lesbian, gay, bisexual and transgender populations.'' New York: Springer. Minority stress theory summarizes these scientific studies to explain how difficult social situations lead to chronic stress and poor health among minority individuals.

John Henryism
John Henryism (JH) is a strategy for coping with prolonged exposure to stresses such as social discrimination by expending high levels of effort which results in accumulating physiological costs. Origins The term was conceived in the 1970s by African-American epidemiologist and public health researcher Sherman James while he was investigating racial health disparities between Black people and others in North Carolina. One of the people he interviewed was a black man, who, despite being born into an impoverished sharecropper family and having only a second grade education, could read and write. The man had freed himself and his children from the sharecropper system, had of farmed land by age 40, but by his 50s, he had hypertension, arthritis, and severe peptic ulcer disease. His name, John Henry Martin, and his circumstances were evocative of folk hero John Henry, an African American who worked vigorously enough to compete successfully with a steam powered machine but di ...

Intergroup Anxiety
Intergroup anxiety is the social phenomenon identified by Walter and Cookie Stephan in 1985 that describes the ambiguous feelings of discomfort or anxiety when interacting with members of other groups. Such emotions also constitute intergroup anxiety when one is merely anticipating interaction with members of an outgroup. Expectations that interactions with foreign members of outgroups will result in an aversive experience is believed to be the cause of intergroup anxiety, with an affected individual being anxious or unsure about a number of issues. Methods of reducing intergroup anxiety and stress including facilitating positive intergroup contact. Causes Widely theorized causes of intergroup anxiety are based on the feeling that interactions will have negative consequences. These can be grouped as follows: *Negative evaluations from the outgroup, often for failing to be aware of and demonstrate appropriate behaviors that are congruent with the outgroup's social norms or possibl ...

African American Health
African Americans (also referred to as Black Americans and Afro-Americans) are an Race and ethnicity in the United States, ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of Slavery in the United States, enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West Africa, West/Central Africa, Central African with some European descent; some also have Native Americans in th ...
