Psychosocial work characteristics and perceived control in relation to cardiovascular rewind at night.


Journal Article

This study examined the effects of psychosocial work characteristics on cardiovascular rewind at night. Ambulatory 24-hr recordings of blood pressure (BP) and heart rate (HR) of 75 borderline hypertensive and 74 normotensive men were related to diary ratings of perceived control (PC) and to scores of psychological demand (P), control (C), and social support (S) at work determined by an occupational classification system. Multiplicative interaction terms for job strain (P x C), isostrain (P x C x S), and Job Strain x Perceived Control (P x C x PC) were calculated. The P x C x PC interaction predicted diastolic BP at night but not at work. A delayed latency to attain the lowest systolic BP during the night was found for jobs with high job strain and isostrain. Low perceived control and social support were associated with higher HR at work and at night. A logistic regression analysis indicated that the interaction between P x C x PC and the body mass index was independently associated with borderline hypertension.
