The cut-off value of impaired fasting glucose should be lower: Based on the associations of fasting blood glucose with blood lipids

The previous study served impaired fasting glucose (IFG), a pre-diabetic state which was much greater than that of diabetic patients, have reached no consensus on its cut-off value. In this study, we aimed to explore the cut-off value of IFG via the associations of blood lipids with fasting plasma glucose (FPG). A cross-sectional study in Jilin province, China, 2012. 13,093 participants aged 18–79 years in Jilin province were involved in the study. The Lamba-Mu-Sigma (LMS) method and generalized additive model (GAM) were used to explore the associations of different levels of FPG and blood lipids. The distributions of FPG, triglyceride (TG) and high-density lipoprotein cholesterol (HDL-c) were significantly different by gender (p
