Objective To know about the spatial distribution characteristics of the poor vision of primary school students in Beijing,so as to provide scientific basis for the formulation of intervention policies and measures. Methods Logarithmic visual acuity chart was used to examine the eyesight of all pupils and the spatial distribution characteristics of the poor vision level were analyzed by Arcgis10.2 software. Results The detection rate of poor vision of primary school students in Beijing in 2017 was 46.8% (361 183/771 392),among which the poor vision rate of female students was higher than that of male students (χ2=67.721,P＜0.01),and the poor vision rate in urban areas was higher than that in rural areas (χ2=1.550,P＜0.01).The poor vision rate in low-grade students was 36.4%,mainly with mild and moderate levels.While the poor vision rate in high-grade students was 58.6%,mainly with moderate and severe levels.The overall Moran′s I index and Z value of primary schools were 0.377 and 4.191,respectively.The poor vision rate of students in Dongcheng district,Xicheng district,Haidian district and Changping district presented high-high concentration,while Huairou district and its surrounding district showed low-low concentration. Conclusions The poor vision rate of primary school students in Beijing is high,and there is a significant positive spatial autocorrelation.The poor vision rate demonstrates a higher level in core area of the city,a decreasing trend in the surrounding areas,and the lowest level in the northeastern and southwestern areas of Beijing.
