| 摘要: |
| 采取随机抽样调查的方法,抽取1610名广西南宁各高校在校大学生,对可能影响视力的每天的上网(使用电脑)时间、睡眠时间、学习时间、运动时间、读书时的视线距离、做眼保健操的情况、吃甜食情况、吃果蔬情况、营养状况和双亲近视情况等10个因素进行问卷调查,所收集的数据用SPSS13.0软件进行处理,通过建立Logistic回归模型对影响近视的因素进行分析。结果发现上网(使用电脑)时间,学习时间,视线距离,做眼保健操情况,运动时间,睡眠时间及营养状况是影响学生视力的7大因素,其中上网(使用电脑)时间和学习时间是最主要的因素。 |

| Abstract: |
| By random sampling 1610 college students who from nanning city of guangxi are extracted.A questionnaire survey includes 10 factors(time of online,time of sleeping,time of study,time of exercises,view distance,the circumstance of doing the eye exercises,nourishment condition,the situation of eating sweet and fruit,etc.) which infulence myopia probably.The data was analyzed by SPSS13.0.Through established logistic regression model,it was found time of on line,time of study,view distance,the circumstance of doing the eye exercises,time of exercises,time of sleep and nourishment condition are the 7 factors mainly affecting student's sight,in which,time of online and time of study are the key factors. |
