Type 2 diabetes, isolated impaired fasting glucose (iIFG), isolated impaired glucose tolerance (iIGT), combined impaired fasting glucose and impaired glucose tolerance, and normal glucose tolerance (NGT) were defined by American Diabetes Association guidelines. Measures included insulin resistance and sensitivity (homeostasis model assessment of insulin resistance [HOMA-IR], modified Matsuda Index, 1\/fasting insulin) and \u03b2-cell function (oral disposition index = [\u0394insulin0\u201330\/\u0394glucose0\u201330] \u00d7 [1\/fasting insulin]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Mean age was 44.2 years (SD, 9.3) and BMI 27.4 kg\/m2 (SD, 3.8); 341 individuals had NGT, 672 had iIFG, IGT, or IFG plus IGT, and 251 had diabetes. Patterns of insulin resistance or sensitivity were similar across glycemic categories. With mild dysglycemia, the absolute differences in age- and sex-adjusted oral disposition index (NGT vs. iIFG, 38%; NGT vs. iIGT, 32%) were greater than the differences in HOMA-IR (NGT vs. iIFG, 25%; NGT vs. iIGT, 23%; each P &amp;lt; 0.0001). Compared with NGT and adjusted for age, sex, BMI, waist circumference, and family history, the odds of mild dysglycemia were more significant per SD of oral disposition index (iIFG: odds ratio [OR], 0.36; 95% CI, 0.23\u20130.55; iIGT: OR, 0.37; 95% CI, 0.24\u20130.56) than per SD of HOMA-IR (iIFG: OR, 1.69; 95% CI, 1.23\u20132.33; iIGT: OR, 1.53; 95% CI, 1.11\u20132.11).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Asian Indians with mild dysglycemia have reduced \u03b2-cell function, regardless of age, adiposity, insulin sensitivity, or family history.
