BackgroundDifferent populations have diverse patterns of relationships between Impaired Fasting Glucose IFG and obesity and lipid markers, it is important to investigate the characteristics of associations between IFG and other related risk factors including body mass index BMI, waist circumstance WC, serum lipids and blood pressure BP in a Chinese population.

MethodsThis was a case-control study of 648 IFG subjects and 1,296 controls derived from a large-scale, community-based, cross-sectional survey of 10,867 participants. Each subject received a face-to-face interview, physical examination, and blood tests, including fasting blood glucose and lipids. Student-s t-test, Chi-square test, Spearman correlation and multiple logistic regressions were used for the statistical analyses.

ResultsFasting plasma glucose FPG was positively correlated with BMI, WC, systolic blood pressure SBP, diastolic blood pressure DBP, triglyceride TG, and total cholesterol TC, and was negatively correlated with high density lipoprotein-cholesterol HDL-C all p < 0.05. BMI was more strongly correlated with IFG than with WC. The correlation coefficient of FPG was remarkably higher with TG 0.244 than with TC 0.134 and HDL-C -0.192. TG was an important predictor of IFG, with odds ratios of 1.76 95%CI: 1.31-2.36 for subjects with borderline high TG level 1.70 mmol-l ≤ TG < 2.26 mmol-l and 3.13 95% CI: 2.50-3.91 for those with higher TG level TG ≥ 2.26 mmol-l, when comparing to subjects with TG < 1.70 mmol-l. There was a significant dose-response relationship between the number of abnormal variables and increased risk of IFG.

ConclusionsIn this Chinese population, both BMI and WC were important predictors of IFG. Abnormal TG as a lipid marker was more strongly associated with IFG than were TC and HDL-C. These factors should be taken into consideration simultaneously for prevention of IFG.
