Key result
Psychosocial factors were significantly associated with urinary catecholamines, and noradrenaline mediated some of the effect of psychosocial factors on blood pressure in middle-aged men.
Why the study?
Are psychosocial factors associated with urinary catecholamines and arterial blood pressure in normal middle-aged men?
Cross-Sectional (n=201)
Yes
Are psychosocial factors associated with urinary catecholamines and arterial blood pressure in normal middle-aged men?
Psychosocial factors are significantly associated with urinary catecholamines, which in turn mediate some of their effects on arterial blood pressure in middle-aged men.
Noradrenaline may mediate psychosocial effects on BP in middle-aged men; cross-sectional data leave causality open and require prospective confirmation.
The present paper investigates the relationship of urinary catecholamines to psychosocial factors and arterial blood pressure in 3 populations, totalling 201, of men aged 35–54 in Western Norway. Urine was collected for 24 hours and the men responded to a psychosocial questionnaire planned to cover broad aspects of their life situation. Blood pressure was measured by Mercury Sphygomano-meter with subjects in a sitting position. A series of significant relationships was found between psychosocial factors and urinary adrenaline and noradrenaline. A highly significant relationship between noradrenaline and blood pressure was found. Some of the effect of psychosocial factors on blood pressure was shown to be mediated by noradrenaline.

Eide et al. (1984) reported a cross-sectional. Psychosocial factors was evaluated on Arterial blood pressure and urinary catecholamines. Psychosocial factors were significantly associated with urinary catecholamines, and noradrenaline mediated some of the effect of psychosocial factors on blood pressure in middle-aged men.
