The aim of this study is to determine whether excessive internet use, television viewing and the ensuing poor lifestyle habits affect low vision in school children in a rapidly developing country. This is a cross-sectional study and 3000 school students aged between six and 18 years were approached and 2467 (82.2%) students participated. Of the studied school children 12.6 percent had low vision. Most of the low vision school children were in the 6-10 years age group and came from middle income backgrounds (41.8%; p = 0.008). A large proportion of the children with low vision spent ≥ 3 hours per day on the internet (48.2%; p< 0.001) and ≥ 3 hours reclining (62.4%; p < 0.001). A significantly smaller frequency of studied children with low vision participated in each of the reviewed forms of physical activity (p < 0.001) yet a larger proportion consumed fast food (86.8%; p < 0.001). Highly significant positive correlations were found between low vision and BMI, hours spent reclining and on the internet respectively. Blurred vision was the most commonly complained of symptom among the studied children (p < 0.001). The current study suggested a strong association between spending prolonged hours on the computer or TV, fast food eating, poor lifestyle habits and low vision.
本研究的目的是确定在一个快速发展的国家中，过度使用互联网、看电视以及随之而来的不良生活习惯是否会影响学童的视力低下。这是一项横断面研究，研究人员接触了3000名6至18岁的在校学生，其中2467名（82.2%）学生参与了研究。在研究的学童中，12.6%有视力低下问题。大多数视力低下的学童年龄在6至10岁之间，来自中等收入家庭（41.8%；p = 0.008）。很大一部分视力低下的儿童每天上网时间≥3小时（48.2%；p<0.001），每天躺着的时间≥3小时（62.4%；p < 0.001）。在参与审查的各项体育活动中，视力低下的学童参与频率明显较低（p < 0.001），但食用快餐的比例较高（86.8%；p < 0.001）。分别在视力低下与体重指数、躺着的时间和上网时间之间发现了高度显著的正相关。视力模糊是研究儿童中最常抱怨的症状（p < 0.001）。当前研究表明，长时间使用电脑或电视、食用快餐、不良生活习惯与视力低下之间存在密切关联。
