Objective To understand the status,changes and causes of the body shape of primary and middle school students of Kirgiz nationality in Xinjiang in 2010 and 2014,and to provide basis for improving the physical health of Kirgiz students. Method Data were from students who participated in the 2010 and 2014 National Student Physique and Health Survey in Xinjiang.Height,body weight and chest circumference of students aged 7 to 18 were compared. Results Height,body weight and chest circumferenceof Kirgiz boys in 2014 increased than those in 2010. The average growth values of height,body weight and chest circumference of Kirgiz male students were 1.7 cm,2.5 kg and 0.3 cm, and those values in female students were 1.4 cm,1.9 kg and 1.9 cm,respectively. The increases of height and body weight in boys was higher than those in girls,and the increase of girls′chest circumference was faster than that in boys. There were some significant differences on height,body weight and chest circumference in the age group of 7~18 years old among different years (P<0.05 or 0.01). Conclusions The body shape of Kirgiz students aged 7~18 is growing in Xinjiang,but there is still a large gap with the national average level. So more attention should be paid to take effective measures in order to improve the growth and development of Kirghiz students.
