Among the students with overweight and obesity, the rates of high blood pressure were 19.44% and 25.92%, respectively, which was significantly different (P﹤0.01) from those with normal weight (0.36%). Students with waistline bigger than 80cm had higher rate of high blood pressure than those with waistline smaller than 80cm (P﹤0.01).
