A link between hostility and disease: poor health habits?

The Cook and Medley Hostility (Ho) Scale has been found to predict the occurrence of coronary heart disease, as well as total mortality, and to be related to the severity of coronary artery disease. It has been proposed that the relationship between Ho scores and health status is mediated by an unhealthy psychosocial risk profile. The present study investigated the health habits of 202 young adults; it used a shortened version of TestWell, a self-report inventory of health behaviors. Subjects were classified as high or low scorers on the Ho scale and their overall TestWell scores and those of four subscales were compared. High scorers reported poorer health habits overall (p = .003) and on three of the four subscales (Physical Fitness, p = .04; Self-Care, p = .04; Drugs and Driving, p = .0001). These results suggest that the poor health habits of individuals with high hostility scores may be an additional explanation of the link between hostility and subsequent disease to the psychosocial risk profile explanation recently proposed.
