Abstract:
Objective:To provide references for cardiovascular health management of military pilots by investigating the risk of ischemic cardiovascular diseases (ICVD) in military pilots.Methods:The physical examination data of military pilots in Air Force Healthcare Center for Special Services Hangzhou were retrospectively analyzed. The military pilots were divided into 2 groups by age (22-34 years, 35-56 years), and they were divided into 5 groups by flying hours (≤500 h, 500-≤1 000 h, 1 000-≤2 000 h, 2 000-≤3 000 h, >3 000 h). The 10-year ICVD incidence risk of pilots was evaluated according to the 10-year ICVD incidence risk assessment table of Chinese people. The distribution and influencing factors of absolute risk and relative risk of ICVD incidence in military pilots were analyzed, and the risk factors between different age groups were compared.Results:①A total of 337 military pilots were included, 194 in the 22-34 years group and 143 in the 35-56 years group. ②Absolute risk detection: there were 336 very low-risk military pilots and a low-risk military pilot. Relative risk detection: 87 (25.82%) military pilots were relatively high risk including 41 (21.13%) cases in 22-34 years group, 46 (32.17%) cases in 35-56 years group, the difference between 2 groups was statistically significant ( χ2=5.23, P=0.022); there were 250 (74.18%) relatively low-risk military pilots. ③Among the pilots aged 22-34 years, there was significant difference in relative high-risk ratio between flying hours ( χ2=17.00, P<0.001). The relative high-risk ratio of the pilots with flying hours 500-≤1 000 h was higher than that of pilots with flying hours ≤500 h, and the difference was statistically significant ( P<0.05); the proportion of pilots with elevated triglyceride and low density lipoprotein cholesterol indexes was higher than that of those with normal indicators (all P<0.05). The relative high-risk ratio of pilots with hypertension in 35-56 years group was higher than that of those with normal blood pressure ( χ2=23.70, P<0.001); the proportion of pilots with elevated triglyceride indicators was higher than that of high-risk groups ( P<0.05). ④The smoking rate, BMI and total cholesterol abnormality rate were higher in the 35-56 years group than in the 22-34 years group, and the differences were statistically significant ( χ2=9.71, 29.72, 19.17, P=0.002, <0.001,<0.001). ⑤The aggregation analysis of the risk factors of smoking, BMI, total cholesterol, systolic blood pressure and diabetes showed that the number of risk factor aggregates ≥2 species accounted for 51.04%, and the aggregation of risk factors in different age groups was statistically significant ( Z=6.38, P<0.001). Conclusions:The relative risk of ICVD in pilots is high, and the aggregation of risk factors is serious. Simply improving a single index is hardly to meet the demand of risk reduction. It needs a variety of joint interventions to improve the lifestyle and reduce the abnormal rate of total cholesterol, overweight rate, systolic blood pressure level and smoking rate. It is suggested that ICVD incidence risk prediction score should be routinely used in the risk assessment of chronic diseases in aviation medicine.
