Investigation And Correlation Analysis Of Risk Factors Of Cardiovascular Disease In Pilots

Objective:To provide the scientific basis for prevention and treatment of cardiovascular disease in pilots by analyzing uric acid, blood pressure, blood lipid and flight time, smoking, body weight, and to study respectively on related risk factors of hyperuricemia, hypertension and hyperlipidemia, retrospectively for the nearly past six years.Methods:2563 pilots, examined in a hospital between 2005 and 2010, were divided into different groups, and compared between years, ages, uric acid normal and abnormal groups, blood pressure normal and abnormal groups, ortholiposis and dyslipidemia groups, in biochemical indicators. The hyperuricemia, hypertension, hyperlipidemia and risk factors for the pilots were also analyzed.Results:(1) Uric acid:294 pilots were found to be abnormal in uric acid level. The prevalence rate of hyperuricemia was 13%. In uric acid abnormal group, the total cholesterol, triglycerides, blood pressure and body weight were significantly higher than those in uric acid normal group (P<0.01), whereas, high density lipoprotein cholesterol significantly lower (P<0.01). The diastolic blood pressure, triglyceride and body weight were independent risk factors for hyperuricemia. (2) Blood pressure: In the survey of 2005 cases of pilots, blood pressure abnormal cases were 194. The hypertension prevalence rate was 9.7%. In the abnormal blood pressure group, the age, total cholesterol, triglycerides, flight time, blood glucose, uric acid, body weight were significantly higher than those in normal blood pressure group (P<0.01); The age, triglycerides and body weight were independent risk factors for hypertension. (3) Lipids:In the survey of 2102 cases of pilots, the number of cases of dyslipidemia was 977. The prevalence rate of hyperlipidemia was 46.48%. In the dyslipidemia group, the systolic blood pressure, diastolic blood pressure, flight time, blood glucose, uric acid, weight and smoking status, were significantly higher compared with those in ortholiposis group (P<0.01). The age, blood glucose, uric acid and body weight were the independent risk factors for hyperlipidemia.Conclusion:Risk factors exist in the pilots, which can cause cardiovascular diseases. Therefore, the preventive measures for cardiovascular diseases of pilots should be developed to provide reference in order to ensure flight safety.
