| Unadjusted HR | 1.00 (Reference) | 1.21 (0.96‐1.63) | 1.07 (0.81‐1.43) | 1.67 (1.41‐1.98) |

Incidence density: incidence cases per 1000 person‐year. Model 1: adjusted for age, study area (Ansan or Ansung), diabetes mellitus (baseline, follow‐up), regular exercise, smoking, alcohol intake, HOMA‐IR, CRP, HDL‐C, total calorie intake, sodium intake. Group 1: low BMI (<25 kg/m2) + low BF % (<22.5% in men, <32.5% in women). Group 2: low BMI (<25 kg/m2) + high BF % (≥22.5% in men, ≥32.5% in women. Group 3: high BMI (≥25 kg/m2) + low BF % (<22.5% in men, <32.5% in women). Group 4: high BMI (≥25 kg/m2) + high BF % (≥22.5% in men, ≥32.5% in women).
