摘要
目的分析我国学生视力不良流行的地域分布特征，为制定更有针对性的防近策略和措施提供依据。方法以2005年全国30个省（自治区、直辖市）7～18岁汉族中小学生各年龄组的视力不良检出率为基础资料，计算标准化率，排定位次。结果中国7～18岁中小学生视力不良检出率城男、城女、乡男、乡女依次为52．85％，61．47％，37．22％，46．01％。视力不良流行存在一定的地域特征，江苏、山东、浙江、上海、甘肃、山西、四川、辽宁、宁夏和重庆为“相对高流行区”，贵州、海南、新疆、青海、江西、天津、广西和河南为“相对低流行区”。各地学生的身体发育水平和人口密度与视力不良率存在一定的相关关系。结论在制定全国防近工作规划时，要重点抓好高流行区的防控工作，在这些地区采取强有力的综合防控措施已刻不容缓；其他地区要以高流行区为戒，及时采取防控措施，防止步高流行区的后尘。
Objective To analyze the geographic distribution of poor-vision prevalence in Chinese students, in order to make more effective preventive and therapy strategies and measures. Methods Subjects were Han students aged 7 - 18 yeats from 30 provinces in 2005 Chinese National Survey on Students＇ constitution and Health, based on the poor-vision prevalence in various age groups, the standardized prevalence of poor-vision was calculated and arranged in precedence order. Results The prevalence of poor-vision was 52.85%, 61.47%, 37.22% and 46.01% for the urban boys, urban girls, rural boy＇s and rural girls aged 7 - 18 yeats, respectively. The 30 provinces were divided into three, prevalence districts： High, medium and low prevalence district, the ＂high prevalence district＂ including Jiangsu, Shandong, Zhejiang, Shanghai, Gansu, Shanxi, Sichuan, Liaoning, Ningxia, and Chongqing pl＇ovince; the ＂low prevalence district＂ including Guizhou, Hainan, Xinjiang, Qinghai, Jiangxi, Tianjin, Guangxi and Henan province. There was some correlation between students＇ growth level, density of population and poor-vision prevalence in difference province. Conclusion When making a national plan for poor-vision control and prevention, we must put the stress on the ＂high prevalence district＂. However, corresponding effective measures are also needed in other areas.
