Hematological and immunological effects of stress of air traffic controllers in northeastern Brazil
This study investigates the potential hematological and immunological effects of stress on air traffic controllers. In the study, 30 air traffic controllers and 15 aeronautical information service operators were divided by job responsibility and years of experience. Blood samples were drawn from each participant at 8:00 a.m. and 2:00 p.m. The paired t-test was used to compare monocyte and nitric oxide concentrations and analysis of variance was used for the other parameters. The results showed that the air traffic controller group with 10 or more years of experience presented a significantly lower phagocytosis rate of monocytes at 2:00 p.m. compared to 8:00 a.m. This group also presented lower hemoglobin, mean corpuscular hemoglobin concentration, platelet and leukocyte levels, and increased cortisol concentrations at 8:00 a.m. compared to the other groups. They also showed lower phagocytosis rate of monocytes, and hemoglobin, platelet, leukocyte, basophils and nitric oxide levels at 2:00 p.m. compared to the other groups. These findings indicate that air traffic controllers with ten or more years of experience showed a significant immunological reaction to stress.
