The statistical analysis was conducted using SPSS 10.0 program. Most subjects belonged to medium degree of obesity. Blood cholesterol levels of the subjects were positively correlated with body fat, waist/hip ratio and BMI; HDL-cholesterol levels of the subjects were negatively correlated with anthropometric data and LDL-cholesterol levels of the subjects were positively correlated with body fat. Blood triglycerides levels of the subjects were positively correlated with body weight, body fat, waist/hip ratio and BMI.
