Type A behavior and black physicians: the Meharry Cohort Study.

A group of 261 black, male physicians was examined for the prevalence of Type A behavior and other sociomedical correlates.Type A behavior, as measured by the Jenkins Activity Survey (JAS), was collected together with type of practice specialty, blood pressure, weight, and height. Type A behavior tended to vary by physician practice specialty. The job involvement subscale correlated significantly with blood pressure but total JAS and other JAS subscale measurements did not. The job-involvement relationship with blood pressure parallels James's finding in lower socioeconomic status blacks. Type A behavior was not found to be related to hypertension but did tend to favor leanness.
