Methods By use of cluster sampling, students from 52 schools (1 high school, 11 junior middle schools, 40 primary schools) in Chengguan District were investigated and measured in height, weight, chest circumference and pulse. In the end, all the results were analyzed. Results It showed that height rapid growth appeared during 12-13 years old for boys and the average yearly growth reached 6.8 cm while for girls it appeared during 11-12 years old and the yearly growth reached 6.6 cm. As to the weight rapid growth, the peak status for both boys and girls appeared at 12 years old with no crossing up on the curves of weight growth. Chest circumference for both boys and girls increased continually till 16 years old. On average, for those aged 13-15, boys had equivalent chest circumference as girls.
