The absolute value of the physiological function index was not different from the normal group, the relative value was higher than the normal group. The low score of the low birth weight group was lower than that of the normal group. 2.The scores of the flexion of the sitting group were better than those of the normal group. The (P<0.01).There was a positive correlation between low-body weight group and low-body weight group (P<0.01). There was a positive correlation between low-weight group and obese group (P < 0.01). (P <0.01).There was a low negative correlation between high school girls overweight group and 800 m (P <0.05). conclusion: 1.abnormal weight of high school students in Jiangsu Province, the proportion of overweight and low weight was higher than that of obesity and overweight. 2.There was a positive correlation between low birth weight and age of high school students, but the overweight rate and obesity rate were negatively correlated with age.
