|
At the viewpoint of health promotion, we measured the subjective symptoms of fatigue and stress of 805 pilots. With 30 item questionnaire of subjective symptom and 12 item General Health Questionnaire(GHQ-12), the fatigue and stress of the pilots were measured. The questionnaire for fatigue be comprised of 3 symptom groups of 10 items each, representing dullness and sleepiness(Ⅰ), difficulty in concentration(Ⅱ), bodily projection of fatigue(Ⅲ). The means of the group Ⅰ, Ⅱ, and Ⅲ symptoms were 2.27, 1.33, 0.91 respectively, so the patters of Ⅰ>Ⅱ>Ⅲ indicated that the type of fatigue was
that of mental work. ’Whole body feels tired,’ ’yawing a lot,’ ’head feels muddled,’ ’eye strain,’ ’feel drowsy’ from group Ⅰ, ’Feel anxious about things’ from group Ⅱ were the symptoms that more than 20% of participants complained. 187 persons(27.4%) who have more than 3 of the GHQ-12 score complained statistically significantly more symptoms
in the 3 symptom groups. The partial correlation coefficients of stress and fatigue symptoms group Ⅰ, Ⅱ, and Ⅲ were 0.25, 0.33, 0.27 respectively. All the three were statistically significant. The 3 partial variables were age, regular
sleep and frequency of eating breakfast.
