There were two studies in the current grant. Study 1 reexamined hypothesized relationships of high effort coping and job strain to elevated ambulatory blood pressure (BP) at work and at home in a sample of 288 Black and white men and women stratified by job status. Also, assessments were made of the relationships of these traits to increased epinephrine and norepinephrine responses, other measures of sympathetic activation, adverse lipid profiles, and cardiac and vascular structural changes. Job strain and high effort coping were also related to hypertension prevalence in 576 black and white men and women stratified by job status. The influence of additional psychosocial variables (social support, hostility, anger-in, depressed mood, anxiety) was also examined.
