  1. Categorical variables are presented as sum and percentages, and continuous variables are presented as Mean ± SD. Abbreviation: BMI, Body mass index; WC, Waist circumference; WHR, Waist hip rate. * P values for continuous variables (Analysis of variance) and for Categorical variables (chi-square test); P-value < 0.05 was considered statistically significant
