==Epidemiology & Demographics==
The level of blood pressure regarded as deleterious has been revised down during years of epidemiological studies. A widely quoted and important series of such studies is the [[Framingham Heart Study]] carried out in an American town: Framingham, Massachusetts.  The results from Framingham and of similar work in Busselton, Western Australia have been widely applied.  To the extent that people are similar this seems reasonable, but there are known to be genetic variations in the most effective drugs for particular sub-populations. Recently (2004), the Framingham figures have been found to overestimate risks for the UK population considerably. The reasons are unclear.  Nevertheless the Framingham work has been an important element of UK health policy.

In a summary of recent research Jules P. Harrell, Sadiki Hall, and James Taliaferro  describe how a growing body of research has explored the impact of encounters with racism or discrimination on physiological activity. "Several of the studies suggest that higher blood pressure levels are associated with the tendency not to recall or report occurrences identified as racist and discriminatory."<ref>[http://www.ajph.org/cgi/content/abstract/93/2/243 Physiological Responses to Racism and Discrimination: An Assessment of the Evidence]</ref> In other words, failing to recognize instances of racism has a direct impact on the blood pressure of the person experiencing the racist event. Investigators have reported that physiological arousal is associated with laboratory analogues of ethnic discrimination and mistreatment.


The interaction between high blood pressure and racism has also been documented in studies by [[Claude Steele]], Joshua Aronson, and Steven Spencer on what they term "stereotype threat".<ref>African Americans and high blood pressure: the role of stereotype threat.

'''Age'''<br>
The prevalence of hypertension was found to be 7.3% among those aged 18-39, 32.4% among those aged 40-59, and 65.0% among those aged 60 and over.

The age-adjusted prevalence on hypertension doesn’t vary significantly by gender with a prevalence of 29.7% among men and similarly a prevalence of 28.5% among women.

Overview

Hypertension is considered an epidemic worldwide. It continues to be one of the most common diseases. In October 2013, CDC data from the 2011-2012 National Health And Nutrition Examination Survey (NHANES) demonstrated that the overall age-adjusted prevalence of hypertension among U.S. adults aged 18 and older was 29.1%.[1] Similar surveys conducted in Europe estimated the prevalence of hypertension to be 44%.[2] The prevalence of hypertension increases among older patients and among non-Hispanic black patients, but is similar in both genders.

Epidemiology and Demographics

Hypertension is considered an epidemic worldwide. It continues to be one of the most common diseases. In October 2013, CDC data from the 2011-2012 National Health And Nutrition Examination Survey (NHANES) demonstrated that the overall age-adjusted prevalence of hypertension among U.S. adults aged 18 and older was 29.1%.[1] Similar surveys conducted in Europe estimated the prevalence of hypertension to be 44%.[2] Worldwide data currently estimates that hypertension currently affects approximately 972 million people with yearly incidence rates ranging between 3% and 18%.[3] Data from the 1990s suggested a decrease in the prevalence of hypertension; however, recent data has in fact revealed that hypertension is on the rise again.[3] Despite the high prevalence of hypertension, NHANES reports that there is a significant increase in awareness, treatment, and control among hypertensive patients over the last 10 years.[4]


The prevalence of hypertension varies according to age, gender, and ethnicity which has been underlined by data collected by the NHANES 2011-2012:[1]

Age
The prevalence of hypertension was found to be 7.3% among those aged 18-39, 32.4% among those aged 40-59, and 65.0% among those aged 60 and over. A global rise in systolic blood pressure with age is likely the principle etiology for the increased incidence and prevalence of hypertension among older individuals.

Gender
The age-adjusted prevalence on hypertension doesn’t vary significantly by gender with a prevalence of 29.7% among men and similarly a prevalence of 28.5% among women.

Ethnicity
The age-adjusted prevalence is significantly higher among non-Hispanic blacks at 42.1% in contrast to 28.0% among white non-Hispanic, 26.0% among Hispanic, 24.7% among Asian individuals.
