[Analysis of arterial hypertension and work in the epidemiologic study "Aging, Health and Work"]

We evaluated if work conditions or job strain related to professional activity or to life styles represent a risk factor for arterial hypertension and whether this effect of hypertension is independent of age.

through data collection of epidemiological inquiries ESTEV and VISAT, applied in Italy on a cohort of workers, 32-52 year-old, employed in different productive sectors, we analyzed the relationships on working conditions (exposure to certain risks or job strain), life styles and self evaluation of health and arterial hypertension. Hypertension was considered as SAP > or =160 mm/Hg and/or DAP > or =90 mm/Hg, or current antihypertensive treatment.

the results refer to 1104 workers, 76% men and 24% women. Prevalence of hypertension was found to be higher among the men than women (33% vs. 22%). Risk estimation in multivariate analysis, by logistic regression model, showed a statistically significant association with certain work-related factors such as: shift work, awkward posture, standing work, doing several tasks contemporarily, being interrupted at work, not being able to take eyes off work. The variables referred to cognitive aspects and work organization tended to be associated to arterial hypertension even when exposure ceased.

both physical and cognitive organisational aspects of work are strongly associated with arterial hypertension. The subjective assessment that workers give to their work is a relevant element. This aspects should be considered as a possible reducible risk factor.
