Prevalence and Incidence of Hypertension


advertisement

About prevalence and incidence statistics: The term 'prevalence' of Hypertension usually refers to the estimated population of people who are managing Hypertension at any given time. The term 'incidence' of Hypertension refers to the annual diagnosis rate, or the number of new cases of Hypertension diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Prevalance of Hypertension: 50 million Americans (NHLBI); 217 per 1000 (NHIS95)
Prevalance Rate: approx 1 in 5 or 18.38% or 50 million people in USA [about data]
Undiagnosed prevalence of Hypertension: more than 15 million (more than 30% of 50 million are undiagnosed)
Undiagnosed prevalence rate: approx 1 in 18 or 5.51% or 15 million people in USA [about data]
  Undiagnosed prevalence statistics about Hypertension: The following statistics relate to undiagnosed cases of Hypertension:
  • 80-85% affected are not treated in England (Coronary Heart Disease Statistics, British Heart Foundation, 2003)

Worldwide prevalence of Hypertension:estimated 600 million people affected worldwide (Cardiovascular Diseases – Prevention and Control, WHO, 2001-2002)

Prevelance of Hypertension discussion: The age-adjusted prevalence of hypertension in overweight U.S. adults (BMI 25 and < 30) is 23.9 percent for men and 23.0 percent for women, compared with 18.2 percent for men and 16.5 percent for women who are not overweight (BMI < 25). The prevalence for obese adults (BMI 30) is 38.4 percent for men and 32.2 percent for women. 14 (Hypertension is defined as mean systolic blood pressure 140 mm Hg, mean diastolic 90 mm Hg, or currently taking antihypertensive medication.)1

Older women are particularly likely to develop high blood pressure. More than half of all women over age 60 have it.2

As many as 50 million Americans may have HBP. Among people age 65 and older, about 40 percent of Whites and 50 percent of Blacks have HBP. 3
