More than 50 million Americans have high blood pressure, and this condition affects nearly 1 billion people around the world. Less than half of these people are on medication, however, and, worse still, only about half of this group, their blood pressure is under good control of such agents. Older people are treated appropriately. Most people with high blood pressure are warm, soft, but even this condition requires attention (Klein, 25-89).
Age and sex
Age is a major risk factor for hypertension. Blood pressure increases with age among both men and women, and the risk of high blood pressure is almost 90%. Two-thirds of Americans 60 years have hypertension. Mature women (over 60 years old) are currently the highest rates of high blood pressure and hypertension, mortality is higher among women than men.
Ethnic origin compared to Caucasians, Afro-Americans have 1.8 pace Fatal stroke 1.5 risk of chronic diseases of the heart and 4.2 times average end-stage kidney disease. About 34% of African-American men and women with hypertension, it may represent more than 40% of all deaths in this group (pandora nla.gov .au).
In fact, the prevalence of high blood pressure among African Americans is among the highest in the world. Rates of hypertension, Hispanics, Native Americans and Caucasians, equivalent (from 24% to 27%). (Persons of Mexican descent, in comparison with the Spanish origin may have lower risk). This figure is significantly lower in Asian/Pacific Islander (9.7% for males and females 8.4%). It should be noted, however, almost 3/4 Japanese American older men were hypertension (Klein, 25-89).
Several theories were considered the reasons for this discrepancy:
Some studies have shown that African-Americans may have lower levels of nitric oxide and a higher level of peptide is called endothelin-1 (ET-1) than in Caucasians. (Nitrous oxide keeps blood vessels, flexible and ...
