  1. aanalyses limited to participants with available data on measured and self-reported height and weight.
  2. bp-value of Kruskall Wallis Test on significant differences between ethnic groups.
  3. cunderestimation of the obesity prevalence by self-reports as a percentage of the true prevalence
  4. *p< 0.05; **p< 0.01; ***p< 0.001 for paired t-test on differences between measured and self reported values.
