Hypertension and objective and self-reported stressor exposure: a review.

A review of the literature on the relationship between blood pressure and stressor exposure revealed a discrepancy between the results of studies based on objective measures of stressor exposure and studies based on self-reports. Whereas in the studies based on objective measures, a clear predominance of positive associations between blood pressure level and stressor exposure was found, in the studies based on self-reports, the results were highly inconsistent. Several moderator variables have been proposed that could explain the discrepancies found in the literature, such as awareness of hypertension and treatment. In studies in which these moderators were taken into account, inverse associations between blood pressure and self-reported stressor exposure have often been found. It is suggested that this result is brought about by altered appraisal of stressors in hypertensives.
