QuickStats: Age-Adjusted Percentage of Adults* Aged >20 Years with Hypertension, by Poverty Level§ --- National Health and Nutrition Examination Survey, United States, 2003--2006
* Age-adjusted to the 2000 standard population using five age groups: 20--34 years, 35--44 years, 45--54 years, 55--64 years, and >65 years.
Hypertension is defined as having measured elevated blood pressure (systolic pressure: >140 mmHg or diastolic pressure: >90 mmHg) and/or taking antihypertensive medication. Persons with elevated blood pressure also might be taking prescribed medicine for high blood pressure. Those taking antihypertensive medication might not have measured elevated blood pressure, but are still classified as having hypertension. Respondents were asked, "Are you now taking prescribed medicine for your high blood pressure?"
§ Poverty level is based on family income and family size.
¶ 95% confidence interval.
The percentage of U.S. adults with hypertension was associated with income, with those at the lowest income level more likely to have hypertension than those in the highest income group.
