We therefore assessed the predictive effect of insulin resistance and insulin secretory dysfunction separately for the progression from normal glucose tolerance (NGT) to impaired glucose tolerance (IGT) and from IGT to diabetes.<\/jats:p>\n                  <jats:p>RESEARCH DESIGN AND METHODS\u2014 Insulin-stimulated glucose disposal (M) (hyperinsulinemic clamp), acute insulin secretory response (AIR) (25-g intravenous glucose tolerance test), and body composition(hydrodensitometry or dual-energy X-ray absorptiometry) were measured in 254 Pima Indians with NGT and in 145 Pima Indians with IGT, who were then followed for 0.5-13 years.<\/jats:p>\n                  <jats:p>RESULTS\u2014 After follow-ups of 4.4 \u00b1 3.1 and 5.5 \u00b13.4 years, 79 (31%) of the subjects with initial NGT had developed IGT, and 64(44%) of the subjects with initial IGT had developed diabetes. In proportional-hazards analyses with adjustment for age, sex, and percent body fat, low M and low AIR were independent predictors of both the progression from NGT to IGT (relative hazards [95% CI] for 10th vs. 90th percentile: M 2.4 [1.2-4.7], P &amp;lt; 0.02; AIR 2.1 [1.1-4.1], P &amp;lt; 0.04) and from IGT to diabetes (M 2.5 [1.3-5.0], P &amp;lt; 0.01; AIR 1.8 [0.99-3.3], P = 0.055).<\/jats:p>\n                  <jats:p>CONCLUSIONS\u2014 During each stage of the development of type 2 diabetes, insulin resistance and insulin secretory dysfunction are independent predictors of worsening glucose tolerance and are, therefore, both targets for the primary prevention of the disease.<\/jats:p>","DOI":"10.2337\/diacare.24.1.89","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T17:51:27Z","timestamp":1173117087000},"page":"89-94","update-policy":"https:\/\/doi.org\/10.2337\/ada-journal-policies","source":"Crossref","is-referenced-by-count":278,"title":["Insulin Resistance and Insulin Secretory Dysfunction Are Independent Predictors of Worsening of Glucose Tolerance During Each Stage of Type 2 Diabetes Development"],"prefix":"10.2337","volume":"24","author":[{"given":"Christian","family":"Weyer","sequence":"first","affiliation":[{"name":"From the Clinical Diabetes and Nutrition Section, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health,Phoenix, Arizona."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.
