摘　　要：目的分析成都市中小学生视力不良的时空特征,为学生近视防控政策制定提供参考。方法以四川省学生体质健康大数据中心2021—2023年成都市中小学生的视力不良数据为研究资料,将成都市各区县划分为主城区、近郊区县和远郊区县三个圈层,采用χ^(2)检验进行组间比较,采用Cochran-Armitage检验分析变化趋势,采用全局及局部Moran's I值分析空间聚集性。结果2021—2023年成都市中小学生视力不良检出率分别为62.47%,61.61%和60.78%,呈下降趋势(Z=-32.01,P<0.01)。各年度间,学段越高的学生视力不良检出率越高,差异均有统计学意义(χ^(2)值分别为161549.47,173471.87,233459.09);从成都市中心区县到四周区县,中小学生视力不良检出率逐渐降低,差异均有统计学意义(χ^(2)值分别为299.20,776.22,633.16)(P值均<0.01)。空间自相关分析显示,成都市域第一圈层以高-高聚类(P<0.01)为主,其中武侯区2023年小学生视力不良检出率出现低-高异常;第三圈层以低-低聚类(P<0.01)为主;第二圈层空间聚集性均无统计学意义(P值均>0.05)。结论成都市近视防控工作取得初步成效;应继续巩固现有成果,并根据区域特点实施针对性的近视防控措施。Objective To analyze the space-time characteristics of poor vision among primary and secondary school students in Chengdu,in order to provide the reference for formulating myopia prevention and control policies for students.Methods The data relating to poor vision among primary and secondary school students in Chengdu from 2021 to 2023 were sourced from the Sichuan Students'Physical Health Big Data Center.The districts and counties of Chengdu were divided into three circles,including the main urban area,suburban districts and counties,and suburban districts and counties.The Chi-square test was used for inter group comparison,and the Cochran-Armitage test was used to analyze the trend of changes.Global and local Moran's I were used to analyze spatial clustering.Results The detection rates of poor vision among primary and secondary school students in Chengdu from 2021 to 2023 were 62.47%,61.61%and 60.78%,respectively,showing a decreasing trend(Z=-32.01,P<0.01).For each year,the higher detection rate of poor vision among students was detected in the higher level of education,and differences were statistically significant(χ^(2)=161549.47,173471.87,233459.09,P<0.01).The rate of poor vision among primary and secondary school students gradually decreased from the central districts and counties of Chengdu to the surrounding districts and counties for each year,and the differences were statistically significant(χ^(2)=299.20,776.22,633.16,P<0.01).The spatial autocorrelation analysis showed that the first circle of Chengdu City was mainly characterized by high-high agglomeration(P<0.01),with the rate of poor vision among primary school students in Wuhou District in 2023 exhibiting a low-high anomaly.The third circle was mainly characterized by low-low aggregation(P<0.01),while the spatial clusterings of the second circle was not significant(P>0.05).Conclusions The myopia prevention and control work in Chengdu has achieved preliminary results.It should continue to consolidate existing achievements and implement targeted my
