目的研究军事飞行人员的胰岛素敏感性与普通居民是否有差别。方法抽取来院疗养和体检的150名军事飞行人员和136名普通居民,抽血查空腹血糖、血胰岛素水平,运用稳态模式法测定胰岛素抵抗指数,同时计算B细胞的分泌功能,比较军事飞行人员与普通居民胰岛素敏感性的差异。结果军事飞行人员IR与普通居民体检人员IR比较,差异有统计学意义(P<0.01),军事飞行人员与普通居民体检人员B细胞的分泌功能比较,差异有统计学意义(P<0.01)。结论军事飞行人员胰岛素敏感性高于普通居民,代谢危险因素聚集及不良生活方式会导致胰岛素敏感性降低。 Objective To investigate whether there is a difference in insulin sensitivity between military pilots and ordinary residents. Methods A total of 150 military pilots and 136 ordinary residents were enrolled in the hospital for recuperation and physical examination. Fasting plasma glucose and insulin levels were determined by blood sampling. Insulin resistance index was measured by steady-state model. B cell secretion was also calculated. Differences of Insulin Sensitivity with Ordinary Residents. Results There was significant difference in the IR of military pilots (IR) and IR among general residents (P <0.01). There were significant differences in the secretory function of B cells among military pilots and ordinary residents (P <0.01). Conclusions Insulin sensitivity of military pilots is higher than that of ordinary residents. The accumulation of metabolic risk factors and unhealthy lifestyles may lead to the decrease of insulin sensitivity.
