  1. Data are presented as age-adjusted means(SD) or percentage unless otherwise indicated; HRQoL, health-related quality of life; ZSDS, zung self-rating depression scale; BMI, body mass index; SD, standard deviation.
  2. *Adjusted for baseline age, BMI, living district.
  3. †p < 0.05 between baseline and follow-up using paired t test for continuous variables, McNemar or Marginal homogeneity test for proportion within group.
  4. ‡p > 0.05 for all the changes between normoglycaemia and pre-diabetes group, with adjustment for baseline corresponding values of HRQoL, ZSDS, BMI and weight, using ANCOVA.
