1 In 5 Young Adults May Have High Blood Pressure

    A group of young adults eating at a restaurantNearly one in five young U.S. adults may have high blood pressure, researchers say in a study, suggesting the problem of hypertension is more widespread than previously thought.

    Hypertension is easy to prevent and inexpensive to treat through diet, exercise and drugs, yet it is the second-leading cause of death in the United States. The Institute of Medicine, part of the National Academy of Sciences that often conducts studies for the government, last year declared high blood pressure a “neglected disease” that costs the U.S. health system $73 billion a year.

    The latest findings by a team at the University of North Carolina at Chapel Hill are in sharp contrast to a federal government study by the National Health and Nutrition Examination Survey that suggested only four percent of young adults might have high blood pressure, a condition that raises the risk of strokes and heart attacks.

    Both studies used the same definition of hypertension: a blood pressure reading of 140 over 90 millimeters of mercury or more. Normal blood pressure is considered to be 120 over 80 or lower.

    “The findings are significant because they indicate that many young adults are at risk of developing heart disease, but are unaware that they have hypertension,” said Quynh Nguyen, a doctoral student at the University of North Carolina at Chapel Hill, whose study appears online in the journal Epidemiology.

    The researchers did not study why the numbers may be rising or relate the findings to U.S. intake of sodium, a major contributor to high blood pressure.

    U.S. health officials say the study is a worrisome signal, but are cautious to embrace the new findings until they have been confirmed in other studies.

    For the study, the team analyzed data on more than 14,000 men and women between 24 and 32 years old in 2008 from the National Longitudinal Study of Adolescent Health, known as Add Health, funded by the National Institutes of Health. They found 19 percent had elevated blood pressure, and only about half of these individuals had ever been told by their doctor that they had the condition.
