Cardiovascular disease mortality in Europeans in relation to fasting and 2-h plasma glucose levels within a normoglycemic range.Diabetes Care. 2010 Oct; 33(10):2211-6.DC
To study mortality in relation to fasting plasma glucose (FPG) and 2-h plasma glucose levels within the normoglycemic range.
RESEARCH DESIGN AND METHODS
Data from 19 European cohorts comprising 12,566 men and 10,874 women who had FPG <6.1 mmol/l and 2-h plasma glucose <7.8 mmol/l at baseline examination were analyzed. Multivariate-adjusted hazard ratios (HRs) and 95% CIs for deaths from cardiovascular disease (CVD), non-CVD, and all causes were estimated for individuals whose 2-h plasma glucose > FPG (group II) compared with those whose 2-h plasma glucose ≤ FPG (group I).
A total of 827 (246) CVD and 611 (351) non-CVD and 1,438 (597) all-cause deaths occurred in men (women). Group II was older and had higher BMI, blood pressure, and fasting insulin than group I. The multivariate-adjusted HRs (95% CIs) for CVD, non-CVD, and all-cause mortality were 1.22 (1.05-1.41), 1.09 (0.92-1.29), and 1.16 (1.04-1.30) in men and 1.40 (1.03-1.89), 0.99 (0.79-1.25), and 1.13 (0.94-1.35) in women, respectively, for group II as compared with group I. HRs were 1.25 (1.05-1.50), 1.09 (0.89-1.34), and 1.18 (1.03-1.35) in men and 1.60 (1.03-2.48), 1.05 (0.78-1.42), and 1.18 (0.93-1.51) in women, respectively, after additional adjustment for fasting insulin in a subgroup of individuals.
In individuals with both FPG and 2-h plasma glucose within the normoglycemic range, high 2-h plasma glucose was associated with insulin resistance and increased CVD mortality.
