To investigates the visual condition and myopia status in primary school students of grade 1 to 3 in Hubei province and to further analyze the influencing factors of myopia, so as to provide theoretical basis for prevention and control of myopia. Cross-sectional study. A total of 18 532 primary school students from grade 1-3 in 26 primary schools from 17 prefecture-level cities in Hubei province were included in the study from March 2017 to July 2017, by using a random stratified cluster sampling method. In this study, 16 955 people were actually surveyed, with a response rate of 91.49%. All students' Visual acuity was measured, a further retinoscopy refraction test after application of Cyclopentolate Hydrochloride Eye Drops was conducted for those whose visual acuity was less than 5.0. The general situation and eye behavior of all students were investigated by questionnaires. Chi-square test was used to compare the prevalence of myopia between different grades, different regions and different genders, as well as the distribution of myopia correlation between different regions, and Logistic regression model was used to analyze the correlation between myopia and related factors. The prevalence of myopia among primary school students of grade 1 to 3 in Hubei province is 24.15% with 12.67% in the first grade, 24.91% in the second grade, 34.95% in the third grade, and the difference was statistically significant (χ(2)=862.28, 0.05). According to the study, mild myopia is the most prevailing condition among myopia students, with the prevalence rate of mild myopia, moderate myopia and severe myopia being 19.21%,4.29%, and 0.64% respectively, and the difference is statistically significant (χ(2)=155.62, 0.05). In addition, the prevalence of myopia is different in each region, which was highest in provincial capitals, followed by non-provincial cities, and the lowest in rural areas, with statistically significant difference (χ(2)=539.57, 0.05). Myopia is generally related to multiple factors, such as the grade, parents' myopia, outdoor activities, continuous closing reading, exposure to electronic products, and extracurricular reading time are related to myopia (0.05). Children's myopia is a public health problem that should not be ignored. The prevalence of myopia among 1-3 grade pupils is 24.15% with an increasing tendency with grade. The occurrence of myopia is related to heredity and eye behavior. -.
为调查湖北省1至3年级小学生的视力状况和近视情况，并进一步分析近视的影响因素，为近视防控提供理论依据。采用横断面研究。2017年3月至2017年7月，运用随机分层整群抽样方法，纳入湖北省17个地级市26所小学的18532名1至3年级小学生。本研究实际调查16955人，应答率为91.49%。测量所有学生的视力，对视力低于5.0的学生使用复方托吡卡胺滴眼液后进行进一步的散瞳验光检查。通过问卷调查了解所有学生的一般情况和用眼行为。采用卡方检验比较不同年级、不同地区和不同性别的近视患病率，以及不同地区近视相关性分布情况，并采用Logistic回归模型分析近视与相关因素的相关性。湖北省1至3年级小学生近视患病率为24.15%，其中一年级为12.67%，二年级为24.91%，三年级为34.95%，差异有统计学意义（χ(2)=862.28，P<0.05）。研究显示，近视学生中轻度近视最为普遍，轻度近视、中度近视和重度近视的患病率分别为19.21%、4.29%和0.64%，差异有统计学意义（χ(2)=155.62，P<0.05）。此外，各地区近视患病率不同，省会城市最高，其次是非省会城市，农村地区最低，差异有统计学意义（χ(2)=539.57，P<0.05）。近视一般与多种因素有关，如年级、父母近视情况、户外活动、持续近距离阅读、接触电子产品以及课外阅读时间等均与近视有关（P<0.05）。儿童近视是一个不容忽视的公共卫生问题。1至3年级小学生近视患病率为24.15%，且随年级升高有上升趋势。近视的发生与遗传和用眼行为有关。-
