JOB STRAIN AND MARITAL STRESS CAN RAISE BLOOD PRESSURE

NEW YORK, NY ? Job strain and marital stress factors are a deadly blood pressure increasing duo, according to results of the Double Exposure study presented at the American Society of Hypertension?s Nineteenth Annual Scientific Meeting.

?The Double Exposure study was designed to determine if people under stress go on to develop higher levels of ambulatory blood pressure, possibly moving them along the pathway to hypertension,? said Sheldon Tobe, MD, lead investigator from Sunnybrook and Women?s Health Science Centre, Toronto. ?Double Exposure refers to the possible interaction between job and marital factors on new and existing hypertension.

?Most job strain studies have been in men,? he explained. ?Double Exposure looks at both men and women and psychosocial factors on sustained blood pressure. We wanted to see whether and how job strain and marital cohesion are related to ambulatory blood pressure over a 24 hour span, during work hours and in face-to-face contact with a spouse?

The investigators recruited 248 subjects (135 women and 113 men) from Sunnybrook and Women?s Health Science Centre, a large teaching hospital. Eligible subjects were working fulltime, in cohabiting relationships and untreated for hypertension. Their mean age was 50.8; 225 (91%) had some form of post-secondary education; 28 (11.6%) consumed more than 10 alcoholic drinks per week; 20 (8.1%) were smokers and 84 (34%) had high blood pressure.

Job strain was derived from the Job Content Questionnaire and marital cohesion from the Dyadic Adjustment Scale, two widely used and validated measurements. The investigators found 52 (21.3%) of the study participants had job strain, and 179 (72.2%) were in a satisfactory and cohesive relationship.

Ambulatory blood pressure monitors were used to record blood pressure. The monitor, a small non-invasive device, automatically measures blood pressure while the subjects are awake and while they are sleeping.
