【摘要】 目的 了解长沙市中小学生超重肥胖流行现状及近3年来超重肥胖变化趋势，为进一步制定肥胖防控策略提供参考依据。方法 采用2019—2021年长沙市连续3年的学生常见病监测项目调查数据，选取资料完整的13 350名中小学生作为分析对象。Logistic回归模型分析超重或肥胖检出率的变化趋势。结果 2021年，长沙市中小学生超重检出率为17.18%，肥胖检出率为13.38%，超重和肥胖检出率男生均高于女生（均P<0.05），肥胖检出率小学高于初中和高中（P<0.01）。肥胖率由2019年的10.69%增至2021年的13.38%，调整地区、性别、年龄后，肥胖检出率整体呈上升趋势(χ²_趋势=16.209,P<0.01)；但2021年肥胖率平均增长速度低于2020年（11.88%vs 17.40%）。结论 2019—2021年长沙市中小学生肥胖检出率呈上升趋势，增长速度放缓，但仍处于流行状态；应重点对小学生采取综合性干预措施，遏制超重肥胖的发生发展。更多还原

【Abstract】 Objective To understand the current prevalence of overweight and obesity among primary and secondary school students in Changsha City and the trend of changes in overweight and obesity in the past three years,so as to provide a reference for further developing obesity prevention and control strategies. Methods Using the survey data of the Common Disease Monitoring Project for Students in Changsha from 2019 to 2021,13 350 primary and secondary school students with complete data were selected as the analysis objects. The logistic regression model was used to analyze the trend of changes in the detection rate of overweight or obesity. Results In 2021,the detection rate of overweight among primary and secondary school students in Changsha was 17.18%,and the detection rate of obesity was 13.38%. The detection rate of overweight and obesity in boys was higher than that in girls(both P<0.05),and the detection rate of obesity in primary schools was higher than that in junior high schools and high schools(P<0.01). The obesity rate increased from 10.69% in 2019 to 13.38% in 2021. After adjusting for region,gender,and age,the overall detection rate of obesity showed an upward trend （χ2trend=16.209,P<0.01）;however,the average growth rate of obesity in 2021 was lower than that in 2020(11.88% vs 17.40%). Conclusion From 2019 to 2021,the detection rate of obesity among primary and secondary school students in Changsha showed an upward trend with a slowing growth rate,but it was still in an epidemic state. Comprehensive intervention measures should be focused on primary school students to curb the occurrence and development of overweight and obesity.更多还原
