[ Methods] The subjects were a-bove 40 years old and their FPG values were between 6.1 -6.9 mmol/L.The FPG,TC,TG,HDL-C, LDL,height,weight,waist circumference ,hip circumference of the subjects were measured 2 times.A ques-tionnaire about life style and cognition about diabetes was conducted in 2012 among the subjects . [ Results] The IFG subjects were under continuous observation for 2 years.Their overall level of IFG was increased , which was found to be statistically significant .Those diagnosed with diabetes accounted for 9 .85%of the total .Logistic Regression Analysis showed that BMI was the risk factor for IFG subjects in the rise of FPG. [Conclusion] On the whole, for IFG people of 40 or above, overall FGP value was on a growth trend during the past 2 years.The influencing factor is thought to be BMI .
