Study Finds Hostility, Impatience Increase Hypertension Risk

Impatience and hostility -- two hallmarks of the "type A" behavior pattern -- increase young adults' long-term risk of developing high blood pressure, according to a study in the Journal of the American Medical Association.

Researchers also found that as impatience and hostility increased, so did the risk of high blood pressure. However, other psychological and social factors, such as competitiveness, depression, and anxiety did not increase hypertension risk.

The research was conducted by scientists at the Northwestern University Feinberg School of Medicine in Chicago, the University of Pittsburgh, the University of Alabama at Birmingham, and the Birmingham Veterans Affairs Medical Center.

This was the first prospective study to examine, as a group, the effects of key type A behaviors, depression, and anxiety on the long-term risk for high blood pressure. Earlier studies had mostly looked at individual psychological and social behaviors and found conflicting results.

High blood pressure, also known as hypertension, is a major risk factor for heart disease, kidney disease, and congestive heart failure, and is the chief risk factor for stroke. Normal blood pressure is a systolic (top number) of less than 120 millimeters of mercury (mm Hg) and a diastolic (bottom number) of less than 80 mm Hg; high blood pressure is a systolic of 130 mm Hg or higher, or a diastolic of 80 mm Hg or higher. Numbers in between are referred to as "pre-hypertension" and are associated with an intermediate risk of complications related to high blood pressure.

About 75 million Americans -- one in three adults -- have high blood pressure, and prevalence increases sharply with age: The condition affects about 7.5% of those ages 18-39, 33% of those ages 40-59, and 63% of people ages 60 and older.

"Although high blood pressure is less common among young adults, young adulthood and early middle age is a critical period for the development of hypertension and other risk factors for heart disease," said lead author Lijing L. Yan, PhD, MPH, adjunct associate professor of preventive medicine at Feinberg School of Medicine at Northwestern University. "Previous research on young adults is limited, and our study helps to fill that gap."

The study used data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, which involved 3,308 black and white men and women from four metropolitan areas (Birmingham, AL, Chicago, IL, Minneapolis, MN, and Oakland, CA). The participants were aged 18-30 at the time of their enrollment in the ongoing study.

Participants had periodic physical exams, which included blood pressure measurements and self-administered psychosocial questionnaires. Fifteen percent of all the participants had developed high blood pressure by ages 33-45.

Five psychological/social factors were assessed: time urgency/impatience, achievement striving/competitiveness, hostility, depression, and anxiety. The first three are key components of the type A behavior pattern and were assessed at the start of the study; the other two behaviors were assessed five years later. The factors were assessed by different scales based on the psychosocial instrument used but, in every case, a higher score meant the most intense degree of the behavior.

Time urgency/impatience was rated on a scale from zero to 3-4. After 15 years, participants with the highest score of 3-4 had an 84% greater risk of developing high blood pressure and those with the second highest score of 2 had a 47% greater risk, compared with those with the lowest score of zero.

Hostility was rated on a score of 0 to 50 and then categorized into quartiles. After 15 years, those in the highest quartile had an 84% higher risk of high blood pressure and those in the second highest quartile had a 38% higher risk, compared with those in the lowest quartile.

No significant relationship was found for the other factors.

Results were similar for blacks and whites and were not affected by age, gender, education, or blood pressure at the time of enrollment. They also held regardless of the presence of such established high blood pressure risk factors as overweight/obesity, alcohol consumption, and physical inactivity.

The researchers state that the rise in blood pressure due to psychological and social factors may be caused by a complex set of mechanisms and is not well understood. For instance, they note that stress could activate the sympathetic nervous system, causing a series of heart and blood vessel repercussions, including narrowing of the blood vessels and an increase in blood pressure.

"This long-term study has given us much-needed information about the effects of psychological and social factors," said Catherine Loria, PhD, FAHA, CARDIA Project Officer at the NHLBI. "But more research must be done on this topic, especially considering the widespread prevalence of high blood pressure in the U.S. and the fast pace of our lives."
