title: Prevalence of Type A behavior in untreated hypertensive individuals.
abstract: Type A behavior has been associated with coronary heart disease as well as high cholesterol and smoking, major risk factors for coronary heart disease, but the data indicating a similar association with hypertension are inconsistent. Since past studies have usually based hypertension on a single blood pressure assessment or have often included treated hypertensive patients, this inconsistency is not surprising. The current study compared the prevalence of Type A behavior (assessed by Rosenman's structured interview) between 109 untreated hypertensive subjects and 109 age-, sex-, ethnic-, and occupation-matched normotensive subjects. Hypertension status was based on five repeated assessments over a 5-month period. Results indicated that Type A behavior is more prevalent in untreated, mildly hypertensive employed individuals than occupationally matched normotensive subjects. Type A component analysis confirmed the importance of hostility and certain vigorous voice stylistics in predicting cardiovascular conditions. These findings, taken together with the evidence linking Type A behavior with high cholesterol and cigarette smoking, further support the view that this behavior pattern is associated with increased risk of coronary heart disease.
