飞行负荷对民航飞行人员血脂水平的影响

目的研究飞行负荷对民航飞行人员血脂水平的影响。方法采集飞行人员静脉血测定血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)。对飞行时间、飞行人员的年龄、体重指数(BMI)、家族史、吸烟、饮酒和运动状况进行调查分析。结果高血脂组飞行人员的年平均飞行时[(561．14±234．90)h]明显高于非高血脂组[(500．62±243．65)h],差异有统计学意义(P＜0．05)；年平均飞行时在800 h以上的飞行人员TG[(1．6l±0．10)mmol/L]明显高于年平均飞行时低于400 h组的飞行人员[(1．3l±0．65)mmol/L],差异有统计学意义(P＜0．05)。高血脂中以30～39岁年龄段的飞行人员所占比例最高。结论年均飞行时是影响飞行人员血脂水平的主要因素之一。

Effect of flying burthen on blood lipid level in civil aviation aircrew

OBJECTIVE: To investigate the effect of flying burthen on blood lipid level in civil aviation flight personnel. METHODS: The level of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) were determined by kits. The relationship between the blood lipid levels and the flight personnel's flying hours, body weight index, smoking, drinking and sport were investigated. RESULTS: The average annual flying hours of hyperlipidemia group [(561.14 +/- 234.90) h] was significantly higher than that of non-hyperlipidemia group [(500.62 +/- 243.65) h] (P < 0.05). The level of TG of the average annual flying hours more 800 h [(1.61 +/- 0.10) mmol/L] were significantly higher than that of less than 400 h group [(1.31 +/- 0.65) mmol/L]. The morbidity rate of hyperlipidemia among the age 30 to 39 years old flight personnel was the highest. CONCLUSION: The average annual flying hours is one of primary factors affecting blood lipid in flight personnel.
