To understand the obesity, overweight and malnutrition status of primary and secondary school students in Karamay from 2014 to 2021, and to provide basis for targeted interventions on nutritional status of primary and secondary school students.
70 792 autumn physical health monitoring data of primary and secondary school students in Karamay from 2014 to 2021 were collected, and SPSS 22.0 software was used. Chi square tests were used for gender comparisons, and trend chi square tests were used for statistical analysis of age groups and years.
The malnutrition rate of primary and secondary school students in Karamay City decreased from 11.4% in 2014 to 5.7% in 2021 (χ2=1 329.791, P<0.01), and the overweight and obesity rates increased from 14.1% and 8.4% to 17.2% and 14.0% respectively (χ2=687.21 and 725.13, respectively, with P<0.01). From 2014 to 2021, the detection rates of malnutrition (except 2018), overweight and obesity (except 2014) in boys were higher than those in girls (P<0.01).
The malnutrition status of primary and secondary school students in Karamay City has been improved yearly, but the overweight and obesity rates have shown an increasing trend year by year. The bipolar problem of male students’ nutritional status is more prominent than that of female students. Schools and health management departments should carry out targeted interventions and countermeasures.
