Data presented as frequency and percentage. BMI, Body mass index. BMI was calculated using the standard method as weight in kilograms divided by the square of height in meters. Based on the World Health Organization (WHO) classification for obesity, patients were defined as underweight (BMI < 18.5 kg/m2), normal (BMI 18.5–24.99 kg/m2), overweight (BMI ≥ 25.00 kg/m2), and obese (BMI ≥ 30.00 kg/m2) [World Health Organization (WHO), obesity: preventing and managing the global epidemic, WHO Technical Report Series 894, Geneva, Switzerland, 2000].
