  1. Model 1 was unadjusted, whereas model 2 was adjusted for age, mean daily alcohol intake, smoking, and physical activity. Model 3 was adjusted for age, mean daily alcohol intake, smoking, and physical activity and accounted for the complex sampling design and appropriate sampling weight of the national survey
  2. Abbreviations: WHtR waist to height ratio; CI confidence interval; Q1 first quartile; Q2 second quartile; Q3 third quartile; Q4 fourth quartile
  3. *Mean (95 % CI) were calculated by using analysis of covariance and statistical significance was defined as P < 0.001 for all analyses
