Masked hypertension in air traffic controllers at work

Abstract

Objective. To study the features of changes in hemodynamic parameters in the air traffic controllers at work and the rate of “masked” hypertension. Design and methods . We examined 55 air traffic controllers from Moscow Centre for Automated Air Traffic Management of the Federal State Unitary Enterprise “State Corporation for Air Traffic Management” and 30 information security specialists who formed the comparison group. The groups were comparable by age, work experience (by the specialty), and the level of office blood pressure (BP). We assessed the main cardiovascular risk factors, and blood pressure parameters by 24-hour ambulatory blood pressure monitoring (ABPM). Results. Despite comparable rates of cardiovascular risk factors, the air traffic controllers demonstrate higher BP levels and higher rates of masked hypertension. According to 24-hour ABPM masked hypertension was detected in 40 % air traffic controllers, which is twice higher than in the comparison group. In addition, the air traffic controllers show significant difference in BP levels in working days and daysoff. Conclusions. The high rate of masked hypertension among air traffic controllers might be associated with the peculiarities of professional activity, namely, with the high stress level.
