  1. Values are shown as the mean ± standard deviation (SD)
  2. *There was statistically significant difference between OH and MH groups, P < 0.05
  3. There was statistically significant difference between MH and HH groups, P < 0.05
  4. There was statistically significant difference between OH and HH groups, P < 0.05. One-way ANOVA was used to compare the differences among the three groups, both in males and females. Significant differences were found in height, weight and BMI among subjects in the three groups (F = 6.921, P = 0.001; F = 7.834, P = 0.001; F = 3.361, P = 0.037). Significant differences were found in height, weight and BMI in males among the three groups (F = 6.921, P = 0.001; F = 7.834, P = 0.001; F = 3.361, P = 0.037); no significant differences were found in females among the three groups (P > 0.05)
