Objective To analyze the trend and influencing factors of the change in the detection rate of overweight and obesity among students in Inner Mongolia Autonomous Region from 2019 to 2021,and to provide a basis for strengthe-ning the prevention and control of obesity and promoting physical health of students.Methods Continuous monitoring were carried out for 2019 and 2021 based on the monitoring platform of common diseases and influencing factors of students in In-ner Mongolia Autonomous Region.Students from primary and middle schools and colleges in 12 League cities in Inner Mon-golia Autonomous Region were selected.Data were collected through on-site physical examination and questionnaire survey to analyze the detection rate of obesity and overweight,and the influencing factors of obesity were analyzed by multivariate logistic regression.Results A total of 535 734 students were surveyed.From 2019 to 2021,the detection rates of over-weight were 16.66％,17.29％and 17.29％.The detection rates of obesity were 18.17％,20.47％and 21.08％,re-spectively.The detection rates of obesity were all higher than that of overweight.Among 12 cities,the detection rate of o-verweight in Wuhai City was highest,reaching 20.17％in 2021.The detection rate of obesity in Hulunbuir City was high-est,reaching 26.85％in 2021.The detection rate of overweight and obesity in Wulanqab City were lowest,reaching 15.80％and 15.76％in 2021.Logistic regression analysis showed that students who were often teased for their physical de-fects(OR=1.334,95％CI:1.129-1.577)and often drank sugary drinks(OR=1.118,95％CI:1.017-1.229)had higher rate of obesity.The obesity rate of students who could do moderate and high intensity exercise ≥60 minutes more days in a week(OR=0.957,95％CI:0.936-0.978)was lower.Conclusion The prevalence of overweight and obesity among students increased from 2019 to 2021.Follow-up attention should be paid to the changing trend of overweight and o-besity in different gender,suburban areas and Mengshi.Schools,families and society should coordinate to cope with vari-ous risk factors related to overweight and obesity,take active actions in response to the changing trend,and jointly improve students'physical and mental health.
