Abstract: Objective To explore the status of overweight and obesity in pupils in Luzhou City, and to analyze the correlation between the 5-2-1-0 model and overweight and obesity in pupils, to provide a reference for the prevention and control of overweight and obesity in pupils. Methods From September to October 2021, the random cluster sampling method was used to sample the pupils of grades 4 to 6 from four primary schools in the main urban area of Luzhou City for a physical examination and questionnaire survey. The descriptive analysis method was used to analyze the status of overweight and obesity in pupils, and univariate and multivariate analysis methods were used to analyze the correlation between overweight and obesity and the 5-2-1-0 model. Results A total of 922 pupils were investigated, with an average age of (10.46±0.96) years, and 463 boys (50.2%). Among them, 162 pupils were overweight and obese, and the prevalence of overweight and obesity was 17.6%. The results of multivariate analysis showed that the average daily exercise time (OR=0.560) and weekly intake of sugary drinks (OR=2.656) were related to overweight and obesity in pupils. Conclusions The overweight and obesity status of pupils in Luzhou city is not optimistic. In the 5-2-1-0 model, exercise time and intake of sugary drinks are related to overweight and obesity.
