@P-value for age categories for obese versus non-obese groups were calculated using Mann–Whitney U test. P-value for sex counts in obese versus non-obese groups were calculated using Chi-sq test. Abbreviations: BMI, body mass index; N, number of individuals; SD, standard deviation; IQ, inter-quartile.
#The distribution of the participants onto normal weight (BMI 20 to < 25): overweight (BMI 25 to < 30): obese (BMI 30 to < 40): morbid obese (BMI ≥ = 40) = 88: 224: 253: 280.
