Abstract：Objective To understand the current situation and epidemic trend of overweight and obesity among children and adolescents aged 6-18 years in Jiangmen City from 2017 to 2021. Methods We randomly selected two districts in Jiangmen City by using a cluster random sampling method, and then randomly selected two primary schools, two junior middle schools and one senior high school in each district. The data about height and weight of all students in the 10 schools from 2017 to 2021 were monitored. The diagnostic criteria for overweight and obesity referred to the screening thresholds for overweight and obesity in Chinese school-age children and adolescents released by the National Health and Family Planning Commission in 2018 (industry standard WS/T 586-2018). χ2 test and trend χ2 test were used to analyze the current situation and changing trend of overweight rate and obesity rate in the children and adolescents. Results From 2017 to 2021, the total detection rate of overweight in the children and adolescents in Jiangmen City was 11.57% (2,181/18,857), and the total detection rate of obesity was 9.29% (1,751/18,857). Among them, the detection rates of overweight and obesity in boys were 11.82% and 9.17%, respectively. The detection rates of overweight and obesity in girls were 11.29% and 9.41%, respectively. There were age differences in the detection rates of overweight and obesity among boys, girls and overall children and adolescents. The detection rates of overweight and obesity in the younger age group (6-12 years old) were higher than those in the older age group (13-18 years old), showing statistically significant differences (both P<0.05). No statistically significant differences were found in the detection rates of overweight andobesity among boys, girls and overall children and adolescents between urban and rural areas (all P>0.05). Body mass index (BMI) of the children and adolescents in Jiangmen City increased from (17.98±3.75) kg/m2 in 2017 to (22.47±6.05) kg/m2 in 2021, with an obvious upward trend (χ2=46.540, Ptrend<0.001). BMI in children and adolescents of different genders (male:χ2=22.330, female: χ2=44.425, Ptrend<0.001), different ages (6-12 years old: χ2=65.709, 13-18 years old: χ2=14.586, Ptrend<0.001) and from urban and rural areas (urban area: χ2=27.168, rural area: χ2=39.125, Ptrend<0.001) showed an obvious upward trend over time. Conclusion The detection rates of overweight and obesity and BMI levels of the children and adolescents in Jiangmen City between 2017 and 2021 presented an increasing trend.
