Abstract: Objective To compare the growth and development of students in public schools and migrant workers' schools,and to understand the differences between them,so as to provide scientific basis for health decisions. Methods A total of 6 441 students from 3 public schools and 3 870 students from 4 migrant children's schools in Gusu District of Suzhou City as the research objects.Data of 2018 physical examination were used to calculate the mean age and the average growth value per year,thus to fit the growth trend curve and growth rate curve of students at different age groups in the same period.Height,weight and nutritional status were analyzed and compared between the two groups. Results 1) The height and weight of male and female students in public schools and schools for migrant workers were increasing (P<0.001),and the peak age of the sudden increase except from girls was respectively consistent.The age-specific height,age-specific weight,and year-on-year growth peaks of students in migrant schools were lower than those in public schools.2) In migrant school,the height of boys and girls at the age of 8-12 years,the weight of boys aged 8-9 years and 11-12 years,as well as the weight of girls at the age of 11 years old were significantly lower than those in public schools (P<0.001).3) The detection rate of normal development in boys of migrant schools was higher than that of public schools (P<0.05),and the detection rates of overweight in boys and girls in public schools were higher than those of migrant schools (P<0.05). Conclusion The growth and development level of students in migrant schools is lower than that of public schools,so the attention from multiple departments is required.
