  1. Model 1; adjusted for age, gender, body mass index, dyslipidemia, diabetes mellitus, current smoking.
  2. Model 2; adjusted for age, gender, body mass index, dyslipidemia, diabetes mellitus, current smoking, the prevalence of CVD.
  3. Model 3; adjusted for age, gender, body mass index, dyslipidemia, diabetes mellitus, current smoking, the prevalence of CVD, exercise time.
  4. Model 4: adjusted for age, gender, body mass index, dyslipidemia, current smoking, diabetes mellitus, the prevalence of CVD, exercise time, sitting time.
  5. The low tertile of FMD indicates less than 1.4%.
  6. FMD indicates flow-mediated vasodilation, CVD cardiovascular disease.
