The aim was to assess the influence of childhood reading on the development of myopia after allowance for familial differences in susceptibility.
The study was a cross sectional survey.
Four fishing harbours in Hong Kong in 1989.
Participants were 408 men and women aged 15-39 years old from 159 families.
Histories of school attendance and reading habits in childhood were obtained at interview. Myopia was assessed by retinoscopy. Associations between myopia (defined as a refractive error of at least -1.0D in one or both eyes) and indices of reading in childhood were explored. Myopia was more common in subjects who had attended school (odds ratio = 1.7, 95% CI 1.0-3.0), with the highest risks in those who had started school at the earliest ages and who had spent the most time reading and writing while at primary school. Allowance for familial tendency to myopia produced no diminution in the risks associated with reading.
These data support the hypothesis that reading in childhood is a cause of short sight.
旨在评估在考虑家族易感性差异后，儿童期阅读对近视发展的影响。
该研究为横断面调查。
1989年香港的四个渔港。
来自159个家庭的408名年龄在15至39岁之间的男性和女性。
通过访谈获取儿童期的上学经历和阅读习惯。通过检影验光评估近视情况。探讨近视（定义为一只或两只眼睛的屈光不正至少为-1.0D）与儿童期阅读指标之间的关联。近视在上学的人群中更为常见（优势比=1.7，95%可信区间1.0 - 3.0），在最早开始上学且在小学阶段阅读和书写时间最长的人群中风险最高。考虑家族性近视倾向后，与阅读相关的风险并未降低。
这些数据支持儿童期阅读是近视成因这一假设。
