Abstract：Objective To investigate the status of overweight and obesity among primary and middle school students in Yuyao City, Zhejiang Province, so as to provide the basis for formulating weight management strategies for students. Methods A census was conducted to investigate 72 primary schools and 23 middle schools students in Yuyao City in 2024, and data such as gender and age were collected through questionnaire surveys. Height and weight were measured to calculate the body mass index (BMI). Based on the BMI thresholds for different gender and age groups, overweight and obesity were determined. Results Totally 75 082 individuals were surveyed, including 40 435 boys and 34 647 girls. Among them, 55 172 were primary school students and 19 910 were middle school students. A total of 8 677 overweight and 7 042 obese individuals were identified, with detection rates of 11.56% and 9.38%, respectively. The detection rates of overweight and obesity in boys were higher than in girls (14.01% vs. 8.69%, 11.58% vs. 6.81%, both P<0.05). The detection rate of obesity among students in rural schools was higher than students in urban schools (10.12% vs. 8.18%, P<0.05). The detection rates of overweight and obesity of students with non-local household registration were higher than students with local household registration (12.04% vs. 10.77%, 10.44% vs. 7.64%, both P<0.05). The detection rate of overweight showed an upward trend with age (P<0.05), while no significant age-related trend was observed for obesity (P>0.05). Conclusions The detection rates of overweight and obesity were notably high among primary and middle school students in Yuyao City. Boys, students in rural schools, students with non-local household registration, and older students are the key population.
