Results are expressed as number and frequencies for categorical variables, mean and SD for normal distributed continuous variables and median and IQR for non-normal distributed continuous variables. To determine differences between study groups, we used χ

^{2}for categorical variables, unpaired Student’s t-test in normal quantitative and Mann-Whitney U test for non-normal quantitative variables. P value determines differences between subjects with obesity (BMI ≥30 kg/m^{2}) and without obesity (BMI 18.5–30 kg/m^{2}).BMI, body mass index; DBP, diastolic blood pressure; FPG, fasting plasma glucose; HbA1c, glycated haemoglobin; HDL-C, high-density lipoprotein cholesterol; hsCRP, high-sensitivity C reactive protein; IGT, Iowa Gambling Test; SBP, systolic blood pressure; WCST, Wisconsin Card Sorting Test.
