Of the 3176 first-degree relatives (FDRs) of type 2 diabetes patients, followed between 2003 and 2010, 806 individuals fulfilled the inclusion criteria (FPG ≤ 5.6 mmol/l, absence of IFG or diabetes, age ≥ 30 yr, and at least one review in follow-up period of 5.6 yr), and were included in the study to test for diabetes development. 2370 individuals were exceluded because they did not fulfill the inclusion chriteria or because of pregnancy. 1919 of these did not have a clinical visit in follow up, 451 had FPG ≥ 100. Of the 806 included subjects, 148 developed IFG, 129 IGT, and 43 diabetes. The other 486 FDRs remained without signs of diabetes development. FPG: fasting plasma glucose. IFG: impaired fasting glucose. IGT: impaired glucose tolerance.
