Introduction During last years the life expectation and working duration is increasing and consequently is more frequent visiting during periodical medical surveillance workers affected to chronic illness connected to ageing. Arterial hypertension is an age related medical condition that represent an important risk factor for illness potentially impacting on fitness to work. And also can be worsted by some occupational risk as noise, physical load and mental stress.

Methods We analysed 8628 (3159 females and 5468 males) medical report collected during periodical medical surveillance. Average age were 42,6 years±11,3 (males 42,8 years±11,1, females 42,2 years±11,3) and average BMI were of 24,9 Kg/m² (males 25,8, females 23,5). We consider a worker affected by arterial hypertension when systolic blood pressure is over 140 mmHg or diastolic pressure is more than 90 mmHg or in case he takes antihypertensive therapy.

Result Workers affected to arterial hypertension were 1756, 20,3% of workers (498 females, 15,7% and 1258 males, 23%) with an average age were 49,7 years (males 49,1, females 51,1 years) and average BMI were of 27,5 Kg/m² (males 27,8, females 24,7). These workers resulted totally fit to work were 85,0%, ones with limitations in their fit to work were 14,4%, and only 0,6% were unfit to work. About occupational activities we found the higher percentage of workers with arterial hypertension in drivers were 35,6% (mean age 44,3 and average BMI 26,6) and in construction workers 30,3% (mean age 44,3 and average BMI 26,6) vs i.e. 17,4% of office workers (mean age 42,6 and average BMI 23,9).

Discussion Our analysis confirms the importance of company strategies to promote health promotion at work considering the progressive worker’s ageing. In accord with our data the intervention for reducing cardiovascular risk factor is more urgent in some occupational group as drivers and construction workers.
