目的:掌握辖区内小学生视力不良状况及变化趋势,指导做好儿童视力保健工作,降低视力不良患病率。方法:收集2011~2013年桂林市叠彩区5所城市小学和4所农村小学学生健康体检资料,对视力检查结果进行统计分析。结果:3年间有效视力检查学生总数20 612人,视力不良总检出率为22.89%,3年间视力不良检出率差异有统计学意义(χ2=113.94,P<0.01);视力不良人群中轻度视力低下构成比占62.10%,中度占25.40%,重度占12.50%,差异均有统计学意义(χ2=14.4,P<0.01);女生、男生视力不良检出率分别为25.45%、20.69%,差异有统计学意义(χ2=55,P<0.01)。城市学生视力不良率为25.53%,农村地区为17.47%,差异有统计学意义(χ2=164.6,P<0.01)。结论:3年间视力不良检出率呈逐年增高趋势,以轻度视力低下为主,女生视力不良率高于男生,城市学生明显高于农村地区,与城市学生学业负担过重,用眼时间过长,用眼疲劳有关,需加强儿童视力保护教育,做好早期视力筛查、早期防治。
Objective: To grasp the poor vision of primary school students in the area and the trend of change, to guide children’s visual acuity and reduce the prevalence of poor vision. Methods: The physical examination data of 5 urban primary schools and 4 rural primary school students in Diecai District of Guilin from 2011 to 2013 were collected, and the results of visual acuity test were collected for statistical analysis. Results: The total number of valid visual acuity test students in 3 years was 20 612, the total positive rate of visual acuity was 22.89%. There was a significant difference in the detection rate of visual acuity in 3 years (χ2 = 113.94, P <0.01) The degree of vision loss accounted for 62.10%, moderate 25.40%, severe 12.50%, the difference was statistically significant (χ2 = 14.4, P <0.01); girls, boys poor eyesight were 25.45%, 20.69 %, The difference was statistically significant (χ2 = 55, P <0.01). The rate of poor vision in urban students was 25.53%, and that in rural areas was 17.47%. The difference was statistically significant (χ2 = 164.6, P <0.01). Conclusion: The detection rate of poor eyesight is increasing year by year in three years. The prevalence rate of poor eyesight in girls is higher than that of boys. The urban students are obviously higher than those in rural areas. Overloaded with urban students, Long, with eye fatigue related to the need to strengthen the education of children’s vision protection, early vision screening, early prevention and treatment.
