Measures: Anthropometric measurements including weight, height and waist circumference were carried out on subjects. The weight and height of subjects were measured by SECA digital weight scale and poret al. stadiometer (SECA, Germany) to nearest 0.1 kg and 0.1 cm, respectively. From the readings, body mass index (BMI) was calculated as weight over height square (kg/m2). An inelastic measuring tape (SECA, Germany) was used to measure waist circumferences to the nearest decimal.
