  1. BMI, body mass index; CI confidence interval; KNHANES, Korea National Health and Nutrition Examination Survey.
  2. The table presents the weighted percentage of each socioeconomic group among the total participants.
  3. aBMI was divided into four groups according to Asian-Pacific guidelines: underweight (< 18.5 kg/m2), normal (18.5–22.9 kg/m2), overweight (23.0–24.9 kg/m2), and obese (≥ 25 kg/m2).
  4. bWaist-to-height ratio was calculated as waist circumference divided by height and categorized into two groups: normal (< 0.5) and central adiposity (≥ 0.5).
  5. cDaily calorie intake was categorized into two groups: low (below the median) and high (above the median).
  6. dHigh-risk drinking was defined as consuming ≥ 7 drinks per occasion for men or ≥ 5 for women at least twice per week, classified as ‘yes’ or ‘no’ accordingly.
