[Long-term study of the prevalence of arterial hypertension and outcomes of multifactorial prophylaxis in organized groups of employees].

Aim: To evaluate trends in arterial hypertension (AH) and other risk factors and their changes after active prevention program.

Material And Methods: 1382 male and 1555 female volunteers were included into the group of active prevention at the workplace vs 1024 male and 776 female controls. 5-year follow-up covered 543 males and 569 females from the prevention group against 97 male and 119 female controls. 10-year follow-up covered 82 males and 191 females, 178 males and 118 females, respectively.

Results: Risk factor correction produced a significant decrease in both systolic and diastolic BP levels, prevalence of ECG deteriorations, smoking habits occurrence, overweight. Overall mortality rate, CHD and stroke mortality were significantly less frequent in the prevention group. This group had also less days of temporary disability.

Conclusion: The primary and secondary "in office" prevention for 5 to 10 years diminishes prevalence of risk factors. The temporary disability rate depends on the presence of arterial hypertension. The latter together with the other main risk facts significantly influences cardiovascular and general mortality rates.
