ABSTRACT
Objective@#To investigate the characteristics of geographic distribution and change trend of myopia prevalence for children and adolescents aged 7-18 years old from 2005 to 2014, which provides the basis for the prevention of myopia.@*Methods@#Research material was selected from the data of 2005, 2010, and 2014 Chinese National Survey on Students Constitution and Health, including 31 provinces (with the exception of Hong Kong, Macao, and Taiwan). The complete detection data of binoculus in children and adolescents aged 7-18 years old were selected as our research objects. The research objects of three studies were 233 505, 216 474, and 215 160, respectively. We analyzed the characteristics of geographic distribution and change trend of myopia prevalence for children and adolescents aged 7-18 years old in 31 provinces from 2005 to 2014.@*Results@#The overall myopia detection rates in Chinese children and adolescents aged 7 to 18 years old in 31 provinces were 47.4% (111 707/235 505), 55.6% (120 456/216 474), and 57.2% (122 965/215 160) in 2005, 2010 and 2014, respectively. The growth range in this two phases were 8.0 percentage points, and 1.6 percentage points, respectively, and the difference was statistically significant (P<0.05). The detection rate of Myopia was growing quickly from 2005 to 2010 and only three provinces were in the situation of decline state including Tianjin, Hainan, and Ningxia. 90.3 percent (28/31) of provinces were in the situation of growth state and the growth range was 1.3%-22.3%. The growth of myopia was in the situation of slowdown from 2010 to 2014, and 38.7 percent (12/31) of the provinces were in negative growth districts including Hebei, Shanxi, Inner Mongolia, Zhejiang, Fujian, Shandong, Hubei, Guangxi, Guizhou, Tibet, Qianghai, and Xinjiang. The growth range in other provinces was 0.4%-24.7%.@*Conclusion@#The myopia detection rate was at a higher level and growing constantly in China. There was large difference for myopia of children and adolescents among the 31 provinces. However, the overall growth rate of myopia in children and adolescents was in the situation of a relatively low level form 2010 to 2014.
