Objective To understand physical development of children aged 7 to 12 in the oroqen autonomous banner experimental primary school in the oroqen settlement area from 2013 to 2018, and to provide scientific basis for their physical fitness and health.
Methods According to the standards of “National Student Physical Health Standards (2014 Revised Edition)” and the standards of “Overweight and Obesity Screening for School-age Children and Adolescents” issued by the National Health and Family Planning Commission in 2018, the Oroqen Autonomous Banner Experimental Primary School was 7-12 years old. The average value and growth rate of children’s height, weight and BMI in the past 6 years.

The growth rate of girls aged 7 to 8 was higher than that of boys, and the growth rate of boys aged 9 to 12 was higher than that of girls. With the increase of age, the average BMI of boys and girls aged 7 to 12 showed an upward trend, and the BMI of boys of the same age was always higher than that of girls. Among them, the average BMI of boys aged 7 to 12 in 2018 exceeded the critical value of overweight BMI.
Conclusion The physical shape of children aged 7-12 years increases with age, but the development tends to be overweight and obese, which is related to the natural environment of life, lifestyle, and reduction in physical activity.
