目的　探讨飞行员的葡萄糖耐量、血脂和血清胰岛素水平的变化与其年龄的关系。　方法　 87名健康飞行员和 80名健康地勤人员 ,分别按年龄分为 3个小组 ,其组间距均为 10岁。计算所有检查对象的体重指数 (BMI) ,并检测其血脂、葡萄糖耐量和血清胰岛素水平。　结果　随着年龄的增长 ,葡萄糖耐量逐渐减低 ,血脂和BMI增加 ,且飞行员比较突出 ;尤其是飞行员葡萄糖耐量试验 3h血糖减低显著高于地面人员。年龄每增加 10岁 ,飞行员空腹血糖增高 0 3～ 0 8mmol/L ,而高密度脂蛋白胆固醇水平降低 0 2mmol/L。　结论　糖耐量减低的发生率随年龄增长而增加 ,所以对不同年龄飞行员的膳食及体育训练应当个体化 Objective To investigate the relationship between the changes of glucose tolerance, blood lipids and serum insulin in pilots and their age. Methods Totally 87 healthy pilots and 80 healthy ground crew were divided into three groups according to their ages. The group spacing was 10 years. Body mass index (BMI) was calculated for all subjects and their lipids, glucose tolerance, and serum insulin levels were measured. Results With age, glucose tolerance gradually decreased, blood lipids and BMI increased, and the pilot was more prominent; especially the pilot glucose tolerance test 3h blood glucose was significantly lower than the ground staff. For each 10-year increase in age, the fasting blood glucose of pilots was increased from 0 3 to 0 8 mmol / L, while the HDL cholesterol level was decreased by 0 2 mmol / L. Conclusions The incidence of impaired glucose tolerance increases with age, so dietary and physical training should be individualized for pilots of different ages
