The Effect on Age, Body Weight, Height, Body Mass Index and Smoking to Coagulation Factor VII, VIII and Fibrinogen in Pilots

BACKGROUND: The pilots with cardiovascular events have a possibility for a risk of suffering from sudden incapacitation which is closely related to flying safety. The coagulation factors such as fibrinogen, factor VII, and factor VIII are possibly related to cardiovascular events. Several studies for general population have shown that an increase of those coagulation factors with age, a correlation of Factor VII and fibrinogen with BMI, and of fibrinogen with smoking. However, this study is to find out whether pilots' age, body weight, body mass index (BMI) and smoking are related to the baseline measurement of coagulation factor VII, factor VIII and fibrinogen. METHOD: Samples were taken from 21 pilots from Asiana Airlines: 11 smokers and 10 non-smokers. In order to measure the relationship between age, body weight, BMI, and the coagulation factors, Pearson correlation was used in this analysis. Independent two sampled t-test was used to analyze the correlation between smoking and the coagulation factors. RESULTS: Mean age, mean height, mean body weight and mean BMI of pilots were examined: 38 years, 171.81 cm, 70.67 Kg and 23.94 Kg/m(2). Mean fibrinogen, mean factor VII, and mean factor VIII were also obtained: 236.0 mg/dl, 92.93%, and 60.16%. The coagulation factor VII, factor VIII and fibrinogen were not significant related to age, body weight, BMI, smoking of pilots. CONCLUSION: This study has no correlation between age, body weight, BMI, smoking and the coagulation factors because the age of this study does not have pilots with over 60 years old and healthy behaviors (e.g., exercise, smoking, drinking, etc.) of most pilots are relatively well.

The Relationship between Sick Leave and Pilot's Depression & Anxiety Tendency Using BDI & STAI

BACKGROUND: It is known that depression and anxiety tendency causes physical or social dysfunction. Nowadays, the air travel is increasing as the life condition has been improved so the health of pilots who are in charge of passengers become a very important issue. However, few studies have been done on this issue, especially the relationship between depression & anxiety and medical diseases among them. This study was performed to know the factors affection pilots' sick leave and the correlation between depression & anxiety and sick leave. METHODS: Self administered questionaires were obtained from 123 pilots of one of the airline companies at Seoul from 1st April to 30th may 2003. Depression tendency was measured based upon BDI, the level of anxiety was measured by the standardised STAI and obesity was diagnosed if a BMI is over 25 kg/m2. The data on the subjects' age, position, airlines and the days of sick leave were obtained from personal record. RESULTS: All the study subjects were male with the average age of 40.23+/-7.48 (ranging from 30 to 60). The average age for those who had sick leave was 34.58+/-3.50 and that for those who had not was 40.48+/-7.55 and these two average ages showed difference with statistical significance (P value 0.05). CONCLUSION: This study shows that the average age of sick leave group was lower than that of non-sick leave group (P<0.001). The level of depression and anxiety were not related to the sick leave. The reasons for this seems to be the fact that pilots are healthier than general population and also they pay more attention to their own health. The younger pilots tended to have more days of sick leave, which might be explain that the older pilots were more cautious about the disadvantages of having sick leave but, the younger pilots tend to have strong individualistic personalities.

The Health Promotion Behavior of Pilot and Ground Staff in A-Airlines

BACKGROUND: At present, there is close correlation between health status and lifestyle. Personal lifestyle has influence on health, disease, disorder and early death. Health promotion elements are nutrition, exercise, body weight, alcohol drinking, smoking, stress and so forth. These elements are important on physical and psychosocial well being. A good physical and psychosocial status can increase a personal ability of psychosocial activities. This study surveyed to assess healthy behaviors and to encourage pursuing more health promotion. METHODS: The subjects of this study were 91 pilots and 90 ground staffs in A-Airlines and the period of survey was from march, 2002 to June, 2002. This survey used Wilson's Fantastic Lifestyle Assessment and this assessment was designed to assess healthy behaviors. Data were collected by self-administered questionnaire including 12 items (.relationship of family and friends, activity, nutrition, smoking, toxin, alcohol drinking, sleep, seatbelt, stress, personality, insight, career satisfaction). These data were analyzed statistically by t-test. RESULTS: Mean score of this assessment is 39.16 in pilot, 31.99 in ground staff. Pilot had better healthy behaviors than ground staff in the aspect of all 12 items. Especially, Pilot had better healthy behaviors than ground staff in the aspect of relationship of family and friends, activity, nutrition, smoking, alcohol drinking (drunken amount), sleep, stress, personality, insight, career satisfaction. There were statistically significance (P<0.05). CONCLUSION: In comparing pilot and ground staff were significant difference except drug, seatbelt, frequency of drinking, which means that pilot had better healthy behaviors than ground staff. The result suggests that medical services supply pilots with more thorough and frequently periodic health education. In the future, the role of medical team needs to give a continuous health education of pilots and also, ground staff.
