Model 1, adjusted for age; Model 2, adjusted for age, baseline glycosylated hemoglobin, homeostasis model assessment of insulin resistance, and homeostasis model assessment of β-cell function; Model 3, adjusted for factors in Model 2+physical activity, smoking, alcohol drinking, family history of diabetes, systolic blood pressure, serum cholesterol, triglycerides, and high density lipoprotein cholesterol. Obesity was defined as body mass index ≥25 kg/m2.
