目的：分析大学生手机成瘾与高度近视的关联。

方法：采用横断面研究，于2022-12对陕西省某高校全体在校大学生进行问卷调查，收集社会人口学特征、手机成瘾、高度近视和生活方式情况。采用二元Logistic回归模型分析大学生手机成瘾与高度近视的关联。

结果：纳入19 952名大学生，大学生高度近视患病率为7.31%，手机成瘾率为25.68%，手机成瘾评分为37.59±13.38分。手机成瘾大学生高度近视的发生率高于非手机成瘾大学生(P<0.001)。调整社会人口学特征、生活方式后显示，手机成瘾大学生发生高度近视的风险是非手机成瘾大学生的1.274倍(95%CI：1.131-1.434)。手机成瘾总评分、戒断症状评分、凸显行为评分、社交抚慰评分和心境改变评分每增加1分，大学生高度近视的发生风险分别增加0.9%(95%CI：1.005-1.013)、2.0%(95%CI：1.010-1.030)、2.6%(95%CI：1.010-1.043)、4.8%(95%CI：1.030-1.066)和3.3%(95%CI：1.014-1.052)。

结论：大学生手机成瘾与高度近视的风险增加显著相关，尽早干预手机使用可降低大学生高度近视的发生风险。

METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.

RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.

CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.
