Results Single factor logistic regression showed that the risk factors to myopia were the distance between eyes and book when reading, reading on the bus, hours spend on doing homework every night, exceeding 40 minutes once reading or doing homework, eyestrain and favorite taste. The result of further multiple logistic regression was that distance between eyes and hook when reading, reading on the bus, eyestrain and favorite taste had statistical difference (P.05) to the model.

结果 单因素Logistic回归分析发现，读书时眼睛与书本距离、车上看书、每晚做作业时间、一次看书写作业持续时间超过40min、眼睛酸累和最喜欢咸味是小学生近视发生的危险因素；进一步多因素Logistic回归分析发现，读书时眼睛与书本距离、车上看书、眼睛酸累和最喜欢咸味对模型的作用有统计学意义（P值均＜0.05）。
