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.

===Impact of race===

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.

Overview

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.
