中国，为了解宁夏汉族和回族初中生视力损害及眼镜拥有率。以人群为基础的横断面研究。对宁夏所有124所农村初中的20376名12-15岁儿童进行了视力筛查。通过调查问卷和标准化数学测试分别评估了个人和家庭特征、眼镜拥有率和学习成绩。汉族儿童双眼视力(VA)≤6/12患病率(54.5%)显著高于回族儿童(45.2%)(P<；0.001)，且与年龄、女性、汉族、父母外出工作、课间休息时间短、看电视时间短、学习时间长呈显著正相关。在双眼VA≤为6/12的儿童中，汉族儿童戴眼镜的比例为56.8%，回族儿童为41.5%(P<；0.001)。拥有眼镜与视力较差、家庭财富较多、女性、考试成绩较高、年龄、父母外出工作、对近视和眼镜的了解、学习时间较长和汉族显著相关。这份关于汉族和回族学龄儿童的报告是此类报告中的第一份，证实了这两个群体中视力障碍的高患病率，但在汉族中略高。这两个群体，特别是回族，眼镜拥有率都很低。未来旨在提高眼镜使用率的干预措施和政策应侧重于低收入人群，并寻求纠正有关眼镜安全性和传统眼保健操有效性的错误观念。
To determine the prevalence of visual impairment and glasses ownership among Han Chinese and Hui minority junior high school children in Ningxia Hui Autonomous Region, China. Population-based cross-sectional study. Vision screening was conducted on 20,376 children (age 12–15 years) in all 124 rural junior high schools in Ningxia. Personal and family characteristics, glasses ownership, and academic performance were assessed through a survey questionnaire and standardized mathematics test, respectively. The prevalence of visual acuity (VA) ≤6/12 in either eye was significantly higher among Han (54.5%) than Hui (45.2%) children (P<0.001), and was significantly positively associated with age, female sex, Han ethnicity, parental outmigration for work, shorter time spent outside during recess, shorter time spent watching television and higher time spent studying. Among children with VA≤6/12 in both eyes, only 56.8% of Han and 41.5% of Hui children had glasses (P<0.001). Glasses ownership was significantly associated with worse vision, greater family wealth, female sex, higher test scores, age, parental outmigration for work, understanding of myopia and glasses, higher time spent studying and Han ethnicity. One of the first of its kind, this report on Han and Hui ethnic schoolchildren confirms a high prevalence of visual impairment among both populations, but slightly higher among the Han. Both groups, especially the Hui, have low rates of glasses ownership. Future interventions and policies designed to improve glasses usage should focus on populations with lower incomes and seek to correct erroneous beliefs about the safety of glasses and efficacy of traditional eye exercises.
