下调空腹血糖切点对诊断空腹血糖受损合理性的评估

The estimation of the rationality of lower cut-point (5.6 mmol/L) of FPG for the diagnosis of impaired fasting glucose

广东省佛山市2512名20～94岁职工进行75gOGTT筛查研究显示,空腹血糖(FPG)5.51mmol/L是预测糖尿病的最佳切点,其敏感性和特异性均为80%。FPG5.15mmol/L是预测糖耐量减低(IGT)的最佳切点。因此,降低空腹血糖受损(IFG)的切点是合理的、有临床意义的。

Screening the 2512 employees aged 20- 94 years in Fushan city by 75 g OGTT showed that 5.51 mmol/L of FPG was the optimal cut-point for diagnosis of diabetes with a sensitivity of 80% and a specificity of 80% ; 5.15 mmol/L of FPG was the optimal cut-point for the diagnosis of IGT. It is reasonable to lower FPG cut-point for IFG.
