HbA1c, hemoglobin A1c; FHD, family history of diabetes; fHD, history of diabetes in father; mHD, history of diabetes in mother; sHD, history of diabetes in siblings. Model 1 was unadjusted. Model 2 was adjusted for age, gender, and education. Model 3 was further adjusted for body mass index, waist circumference, smoking status, alcohol consumption, medication to treat hypertension, medication to treat dyslipidemia, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, and triglycerides plus model 2.
