  1. Results are expressed as mean ± standard deviation or number of people and (percentage). Normal weight was defined as a body mass index (BMI) < 25 kg/m2; abdominal obesity was defined as a waist circumference ≥88 cm for women and ≥102 cm in men. Between-gender comparisons performed using Student’s t test or Chi square
