  1. Data are presented as means ± SD or N (%).
  2. All men and women participants were divided into three groups according to tertile of Body Mass Index, respectively.
  3. One-way ANOVA was used to compare means of parameters between three groups in men. Post-hoc analysis: Scheffe.
  4. Analysis of Covariance (ANCOVA) was used to compare means of parameters between three groups after age controlled for women. Post-hoc analysis: Bonferroni.
  5. *significantly different between low BMI and middle BMI or significantly different between low BMI and high BMI, p < 0.05, 1#significantly different between middle BMI and high BMI, p < 0.05.
