Characteristics of the spatial distribution of myopia prevalence for Chinese children and adolescents aged 7-18 years from 2005 to 2014 / 中国学校卫生

ABSTRACT

Objective@#To explore the spatial distribution pattern and characteristics of myopia prevalence for Chinese children and adolescents aged 7-18 years old from 2005 to 2014, and to provide scientific basis for regional myopia prevention and control.@*Methods@#Using data from the National Survey on the Constitution and Health of Chinese Students from 2005 to 2014,children and adolescents aged 7-18 yeaer old with Han and Tibetan ethnicity were included into analysis by using the Arc-GIS 10.2 software.@*Results@#From 2005 to 2014, the overall Moran’s index were 0.13,0.02,-0.06(P>0.05), there was no spatial autocorrelation. Local autocorrelation analysis showed that Shandong, Jiangsu, Shanghai, and Zhejiang Province were "high" aggregation areas, while Hainan and Guangxi Province were "low" aggregation areas.@*Conclusion@#The myopia prevalence of children and adolescents in 31 provinces, municipalities, and autonomous regions shows significant local spatial autocorrelation, most of which are positive correlation; the number of high-high aggregation gradually decreases, while the number of low-low and low-high aggregation gradually increases.
