| description | Background
Experimental studies have shown cardiovascular effects of electromagnetic fields (EMF) emitted by mobile phones
(e.g., prolonged QTc interval and abnormal blood pressure [BP] values). Also, stress may have an impact on the cardiovascular function.
However, there are practically no data regarding the joint effect of exposure to stress and EMF, with both factors pertaining,
e.g., to employees of mobile network operators.
Material and Methods
Out of 208 subjects who had taken part in survey research,
55 workers agreed to undergo resting ECG, 24-h ECG and ambulatory blood pressure monitoring (ABPM). Their health condition,
occupational and life-stress levels and EMF exposure were also assessed.
Results
Among the workers using mobile phones for
more than 60 min daily, the systolic BP values in office measurement and at night-time in ABPM were significantly higher than
among the workers spending less time talking on mobile phones (p = 0.04 and p = 0.036, respectively). The workers with the highest
level of occupational stress showed significantly higher systolic 24-h BP (p = 0.007) and at day-time (p = 0.002), both during work
(p = 0.010) and after work (p = 0.005), and higher diastolic BP values at day-time (p = 0.028). Cardiovascular response was strongly
gender-related: males showed more BP abnormalities while females displayed more impairments in ECG records. The heart rate from
24 h was significantly correlated with the level of occupational stress, after adjusting for gender, life-stress and EMF.
Conclusions
The findings obtained thus far have indicated the need to conduct in-depth studies on the impact of stress and EMF emitted by
mobile phones on the health effects, in order to clarify the observed gender-related differences in cardiovascular response to the
combined exposure to stress and EMF. Med Pr. 2019;70(4):411–24 |
