Abstract

BACKGROUND: New diagnostic criteria for diabetes based on fasting blood glucose (FBG) level were approved by the American Diabetes Association. The impact of using FBG only has not been evaluated thoroughly. The fasting and the 2-hour glucose (2h-BG) criteria were compared with regard to the prediction of mortality. METHODS: Existing baseline data on glucose level at fasting and 2 hours after a 75-g oral glucose tolerance test from 10 prospective European cohort studies including 15 388 men and 7126 women aged 30 to 89 years, with a median follow-up of 8.8 years, were analyzed. Hazards ratios for death from all causes, cardiovascular disease, coronary heart disease, and stroke were estimated. RESULTS: Multivariate Cox regression analyses showed that the inclusion of FBG did not add significant information on the prediction of 2h-BG alone (P>.10 for various causes), whereas the addition of 2h-BG to FBG criteria significantly improved the prediction (P<.001 for all causes and P<.005 for cardiovascular disease). In a model including FBG and 2h-BG simultaneously, hazards ratios (95% confidence intervals) in subjects with diabetes on 2h-BG were 1.73 (1.45-2.06) for all causes, 1.40 (1.02-1.92) for cardiovascular disease, 1.56 (1.03-2.36) for coronary heart disease, and 1.29 (0.66-2.54) for stroke mortality, compared with the normal 2h-BG group. Compared with the normal FBG group, the corresponding hazards ratios in subjects with diabetes on FBG were 1.21 (1.01-1.44), 1.20 (0.88-1.64), 1.09 (0.71-1.67), and 1.64 (0.88-3.07), respectively. The largest number of excess deaths was observed in subjects who had impaired glucose tolerance but normal FBG levels. CONCLUSION: The 2h-BG is a better predictor of deaths from all causes and cardiovascular disease than is FBG.

  • Postprandial glucose peaks are a major contributor to the development of chronic complications of diabetes.

    “Data from many studies support the view that postprandial glucose peaks appear to play a major role in the pathogenesis of chronic diabetic complications.”
  • Complications related to accelerated atherosclerosis are more strongly associated with postprandial glucose peaks than with fasting glucose.

    “In particular, complications related to accelerated atherosclerosis seem to be related to post-prandial peaks more strongly than to fasting glucose.”
  • The dose-response effect of the degree of fasting hyperglycaemia for vascular mortality may be weaker than is the case for postload glucose.

    “The dose-response effect of the degree of fasting hyperglycaemia for vascular mortality may be weaker than is the case for postload glucose.”

  • The DECODE pooling study found IGT to be associated with increased risk of coronary death and total cardiovascular death, independent of the level of FPG, while the converse was not the case.

  • Recent individual-level evidence from prospective studies suggests that fasting hyperglycaemia, postload glucose, and A1c are all robust predictors of vascular mortality, and multivariable adjusted analyses indicate these associations are independent of vascular risk factors such as obesity, blood pressure, triglyceride and lipoproteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
