Objective To investigate the arterial blood pressure levels of fighter pilots and to analyze the risk factors associated with blood pressure in fighter pilots.Methods A retrospective analysis was conducted on the physical examination data and questionnaire data of the fighter pilots who underwent aeromedical assessment at Air Force Healthcare Center for Special Services Hangzhou.They were divided into hypertension group[SBP≥140 mmHg(1 mmHg= 0.133 kPa)and(or)DBP≥90 mmHg],normal high blood pressure group[120 mmHg≤SBP<140 mmHg and(or)80 mmHg≤DBP<90 mmHg]and normal blood pressure group(SBP<120 mmHg and DBP<80 mmHg)according to the blood pressure level.The differences of physiological and biochemical indicators among the pilots of 3 groups were compared,and the risk factors affecting blood pressure were analyzed by multiple Logistic regression.Results A total of 414 fighter pilots were included,with 9(2.17%)in the hypertension group,274(66.18%)in the normal high blood pressure group,and 131(31.64%)in the normal blood pressure group.There were significant differences in age,flying hours,body mass index,waist circumference,fasting plasma glucose,total cholesterol,low-density lipoprotein cholesterol,and blood uric acid among the pilots of different blood pressure groups(F=2.97-11.08,all P<0.05),but no significant difference in HDL-C(P>0.05).The risk factors for increased the blood pressure of fighter pilots included alcohol consumption(OR= 9.865,P=0.021),salt consumption(OR=8.971,P=0.033),blood uric acid(OR=1.013,P=0.046),BMI(OR=1.431,P=0.001)and waist circumference(OR=1.340,P=0.039).The protective factor was the consumption of vegetables and fruits(OR=0.623,P=0.033).Conclusions High sodium diet,overweight or obesity,excessive alcohol consumption,increased blood uric acid and low consumption of vegetables and fruits may be the risk factors result in high blood pressure of fighter pilots.
