Abstract

Fasting plasma glucose concentrations (FPG) predict development of type 2 diabetes. Whether hyperglycemia evolves from normoglycemia gradually over time or as a step increase is not known. We measured plasma glucose and insulin levels during oral glucose testing in 35- to 64-year-old men and nonpregnant women from a population-based survey (Mexico City Diabetes Study) at baseline (n = 2,279) and after 3.25 (n = 1,740) and 7 years (n = 1,711) of follow-up. In subjects with normal glucose tolerance (NGT) on all three occasions (nonconverters; n = 911), FPG increased only slightly (0.23 ± 0.79 mmol/l, mean ± SD; P < 0.0001) over 7 years. In contrast, conversion to diabetes among NGT subjects (n = 98) was marked by a large step-up in FPG regardless of time of conversion (3.06 ± 2.57 and 2.94 ± 3.11 mmol/l, respectively, at 3.25 and 7 years; P < 0.0001 vs. nonconverters). Likewise, in subjects who converted to diabetes from impaired glucose tolerance (n = 75), FPG rose by 3.14 ± 3.83 and 3.12 ± 3.61 mmol/l (P < 0.0001 vs. nonconverters). Three-quarters of converters had increments in FPG above the 90th percentile of the corresponding increments in nonconverters. Converters had higher baseline BMI (30.4 ± 4.9 vs. 27.3 ± 4.0 kg/m2; P < 0.001) and fasting plasma insulin values (120 ± 78 vs. 84 ± 84 pmol/l; P < 0.02) than nonconverters; however, no consistent change in either parameter had occurred before conversion. In contrast, changes in 2-h postglucose insulin levels between time of conversion and preceding measurement were significantly (P < 0.0001) related to the corresponding changes in FPG in an inverse manner. We conclude that, within a 3-year time frame, the onset of diabetes is very often rapid rather than gradual and is in part explained by a fall in glucose-stimulated insulin response.

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.
