了解陕西省宝鸡市7~ 18 岁中小学生视力不良现状、配镜率及相关因素,为中小学生视力保护工作提供参考.方法 于2016年4月收集陕西省宝鸡市10 225 名7~ 18 岁中小学生视力和是否配镜情况,分析学生视力和配镜率现状及其相关因素.结果 学生视力不良率为42.84%,视力不良学生配镜率为53.47%,女生视力不良率(47.37%) 高于男生(38.53%) (χ2 = 81.58,P<0.01),视力不良女生配镜率(54.92%) 高于男生(51.78%) (χ2 = 53.36,P<0.01).使用最小二乘法多元回归分析发现,随着学生年龄增长,视力不良率不断升高(B = 0.073,95%CI = 0.065 ~ 0.080,P<0.01),并伴随视力不良程度不断加深(B= 0.045, 95%CI = 0.029~ 0.061,P<0.01); 配镜率随着年龄而增长(B = 0.042,95%CI = 0.030 ~ 0.054,P< 0.01),男生(B= -0.033, 95%CI = -0.060~ -0.006,P= 0.02) 配镜率相对女生较低.结论 陕西省中小学生视力不良率高,配镜率低; 视力不良程度显著影响配镜率.
Abstract:
Objective To analyze prevalence and associated factors of poor visual acuity and eyeglass wear among primary and secondary school students in Baoji. Methods A vision survey among 10 225 students aged 7 to 18 years in Baoji was conducted in April 2016. Prevalence and associated factor of poor visual acuity and eyeglass wear was analyzed. Results The prevalence rate of myopia was 42.84% in Baoji primary and secondary school students, among which 53.47% wore eyeglasses. The rate of poor visual acuity and eyeglass wear was higher among girls than that of boys. Ordinary least square regression analysis showed that the rate of visual impairment increased, while visual acuity decreased with age. The rate of eyeglass wearing increased with age in general (β = 0.042, 95%CI = 0.030,0.054, P<0.01), while being boy decreased the likelihood of eyeglass wear (β = -0.033, 95%CI =-0.060, -0.006, P= 0.02). Conclusion The prevalence rate of poor visual acuity is high, while the rate of eyeglass wear is low in Baoji prefecture. The degree of visual impairment significantly affects the rate of eyeglass wear.
