  1. Notes: One-way ANOVA or its equivalent Kruskal-Wallis test was used to compare the mean scores of each domains, *significant difference at p<0.05. Post-hoc analysis using Tamhane’s test. a(significant difference between normal vs obese), b (significant difference between overweight vs obese).
  2. BMI categories is based on WHO revised cut-offs for Asian: normal (18.5-22.9) kg/m2, overweight (23.0-27.4) kg/m2 and obese (≥ 27.5 ) kg/m2.
