Personality and the incidence of hypertension among older men: longitudinal findings from the Normative Aging Study.

Personality predictors of hypertension incidence were studied in 838 community-residing men from the Normative Aging Study. They were followed over a mean of 17 years during which time 38% developed hypertension. Stepwise proportional hazards regression was used to identify scales from the Cattell 16 Personality Factor Questionnaire that predicted hypertension incidence, controlling for biomedical, social, and behavioral risk factors. There was a significant negative relation between the personality trait of emotional stability and the incidence of hypertension, controlling for baseline blood pressure, education, and alcohol consumption. These results support those who argue that personality characteristics predict the development of hypertension.
