  1. * The cutpoint of dietary pattern scores for T1 and T2 was −0.3 and 0.5 in the “Rice & Kimchi” pattern, −0.5 and 0.3 in the “Oil, sweets, fish & other vegetables” pattern, −0.5 and 0.1 in the “Red meat & alcohol” pattern, and − 0.4 and 0.3 in the “Grain, bean, nuts, vegetables & fruits” pattern, respectively
  2. * P values were calculated by chi-square test except for blood lipid profile; P values for blood lipid profile were calculated by generalized linear model (GLM) * P < 0.05, **P < 0.01, ***P < 0.001
  3. 1 Household income: low (first quartile), middle-low (second quartile), middle-high (third quartile), high (fourth quartile)
  4. 2 Regular alcohol consumption: ‘yes’ meant drank more than once a month over the past year
  5. 3 Current smoking: ‘yes’ meant smoked > 100 cigarettes over lifetime and still smoking
  6. 4 Physical activity: ‘active’ meant performed moderate-intensity physical activity which requires a moderate amount of effort and causes slightly rapid breathing for ≥30 min once for ≥5 days a week
  7. 1–4 Number of missing values was 521, 472, 519, 461, and 510 for household income, education level, regular alcohol consumption, current smoking status, and physical activity, respectively
