Actually, the percentage of the USA population that has hypertension
is 24%, one in four persons, not 6%. Where did you get the 6% figure.
I wish it were true.
"Prevalence of hypertension in the US adult population. Results from
the Third National Health and Nutrition Examination Survey, 1988-1991.
AU - Burt VL; Whelton P; Roccella EJ; Brown C; Cutler JA; Higgins M;
Horan MJ; Labarthe D
SO - Hypertension 1995 Mar;25(3):305-13.
"The purpose of this study was to estimate the current prevalence and
distribution of hypertension and to determine the status of
hypertension awareness, treatment, and control in the US adult
population. The study used a cross-sectional survey of the civilian,
noninstitutionalized population of the United States, including an
in-home interview and a clinic examination, each of which included
measurement of blood pressure. Data for 9901 participants 18 years of
age and older from phase 1 of the third National Health and Nutrition
Examination Survey, collected from 1988 through 1991, were used.
Twenty-four percent of the US adult population representing 43,186,000
persons had hypertension. The age-adjusted prevalence in the
non-Hispanic black, non-Hispanic white, and Mexican American
populations was 32.4%, 23.3%, and 22.6%, respectively. Overall, two
thirds of the population with hypertension were aware of their
diagnosis (69%), and a majority were taking prescribed medication
(53%). Only one third of Mexican Americans with hypertension were
being treated (35%), and only 14% achieved control in contrast to 25%
and 24% of the non-Hispanic black and non-Hispanic white populations
with hypertension, respectively. Almost 13 million adults classified
as being normotensive reported being told on one or more occasions
that they had hypertension; 51% of this group reported current
adherence to lifestyle changes to control their hypertension.
Hypertension continues to be a common finding in the general
population. Awareness, treatment, and control of hypertension have
improved substantially since the 1976-1980 National Health and
Nutrition Examination Survey but continue to be suboptimal, especially
in Mexican Americans."
Here's the story on sodium:
Sodium
American Heart Association recommendation: Eat less than 6 grams of
salt (sodium chloride) per day (2,400 milligrams of sodium).
Sodium intake may be a primary factor in the development of high blood
pressure (hypertension), which is a major risk factor for heart
attack.
About half of the people with hypertension and 30 percent of the
general public are described as "salt sensitive." This means that
their blood pressures are likely to increase when they eat a
high-sodium diet, and conversely, their blood pressures may be lowered
by limiting dietary sodium.
Salt sensitivity is difficult to accurately diagnose. Therefore,
appropriate sodium recommendations are a subject of great debate among
nutrition experts. Some believe that all people should limit their
sodium intakes (to 2,400 mg/day) to either treat or prevent
hypertension, regardless of their present blood pressure level.
Others, though, advise that only people with hypertension or those who
are believed to be salt sensitive need to limit sodium in their diets.
Nutrition researchers are still trying to tease out the exact role of
sodium in hypertension. A major study in this area is DASH (Dietary
Approaches to Stop Hypertension). This study found that a diet rich in
fruits, vegetables, and low-fat dairy products, and low in saturated
fat, cholesterol, and saturated fat-now called the DASH diet-helped
lower blood pressure. The second phase of the study found further
reductions in blood pressure when the DASH diet was combined with a
sodium intake of no more than 2,400 mg/day.
