目的分析深圳市小学生视力不良流行现状及其地域空间分布特征。
方法采用横断面研究方法,由深圳市儿童青少年近视防控中心组织视力筛查联盟医院于2019年采用对数视力表对深圳市10个行政区全部在校1~6年级小学生进行视力检查,计算不同行政区、不同性别和年级学生视力不良患病率,并采用Arcgis10.2软件对小学生视力不良患病率进行空间特征分析。
结果共对1 044 545名小学生进行了视力检查,发现总体视力不良患病率为53.4%(557 748/1 044 545),原特区内小学生视力不良患病率为56.7%(172 771/304 532),高于原特区外的52.0%(384 977/740 013),差异有统计学意义( χ 2=192.412, P<0.001);女生视力不良患病率为56.7%(268 201/473 164),高于男生的50.7%(289 547/571 381),差异有统计学意义( χ 2=375.434, P<0.001);随年级的升高,深圳市小学生视力不良患病率先降低再升高,大体呈升高趋势,1~6年级学生视力不良患病率分别为49.8%(99 615/200 203)、44.0%(86 521/196 800)、47.2%(82 848/175 331)、54.5%(89 737/164 731)、60.8%(96 271/158 298)和68.9%(102 756/149 182),差异有统计学意义( χ 2=2 871.017, P<0.001)。深圳市小学生视力不良患病率全局空间自相关 Moran I指数为0.278,深圳市光明区小学生视力不良患病率局部空间自相关 Moran I指数为0.933,局部 Geary系数为0.78,光明区及周边区域小学生视力不良患病率呈现低-低值聚集。
结论深圳市小学生视力不良患病率存在空间聚集性。
ObjectiveTo analyze the prevalence of poor vision and spatial distribution characteristics among primary school students in Shenzhen.
MethodsA cross-sectional study was conducted.Vision screening among primary school students in Shenzhen was carried out by myopia screening hospitals organized by Shenzhen Myopia Prevention and Control Center for Children and Adolescents using the logarithmic visual acuity chart in 2019.The prevalence of poor vision in different districts, different genders and different grades was calculated.Spatial distribution of the prevalence of poor vision was analyzed with Arcgis 10.2 software.This study adhered to the Declaration of Helsinki.Written informed consent was obtained from guardian of each subject.The study protocol was approved by an Ethics Committee of Shenzhen Eye Hospital (No.20201230-06).
ResultsA total of 1 044 545 students received the visual acuity examination.The prevalence of poor vision among primary school students in Shenzhen in 2019 was 53.4%(557 748/1 044 545). The prevalence of poor vision among primary school students in the former Shenzhen Special Economic Zone was 56.7%(172 771/304 532), which was higher than 52.0%(384 977/740 013) in areas outside the former Shenzhen Special Economic Zone, and the prevalence of poor vision among girls was 56.7%(268 201/473 164), which was higher than 50.7%(289 547/571 381) among boys, and the differences were statistically significant ( χ 2=192.412, 375.434; both at P<0.001). As the grade increased, the prevalence of poor vision firstly decreased and then increased, showing an increasing tendency in general.The prevalence rate of poor vision among primary school students among grade 1 to 6 was 49.8%(99 615/200 203), 44.0%(86 521/196 800), 47.2%(82 848/175 331), 54.5%(89 737/164 731), 60.8%(96 271/158 298), and 68.9%(102 756/149 182), respectively, and a significant difference was found ( χ 2=2 871.017, P<0.001). The global Moran I index in Shenzhen was 0.278.The local Moran I index and Geary coefficient in Guangming District were 0.933 and 0.78, respectively.The prevalence of poor vision in Guangming District and its surrounding areas was a low-low cluster.
ConclusionsThe prevalence of poor vision among primary school students in Shenzhen is spatially aggregated.
