目的：分析近视防控门诊7～14岁儿童干眼的患病率及其危险因素。

方法：纳入2021-12/2022-02就诊于天津医科大学眼科医院近视防控门诊的7～14岁儿童222例，收集纳入儿童的一般资料，通过眼表疾病指数(OSDI)量表和Keratograph 5M非侵入性眼表综合分析仪评估纳入儿童干眼患病率，并采用Logistic回归模型分析干眼发生的危险因素。

结果：近视防控门诊儿童干眼的患病率为27.9%。Logistic回归分析显示，过敏性结膜炎(OR=2.31，95%CI=1.12～4.78，P=0.02)、屈光不正(OR=5.57，95%CI=2.40～12.94，P<0.01)、每天使用电子产品总时间>2h(OR=2.74，95%CI=1.11～6.78，P=0.03)、每天使用电子产品打游戏时间>2h(OR=2.33，95%CI=1.12～4.84，P=0.02)、每天户外活动时间≤2h(OR=4.28，95%CI=2.02～9.07，P<0.01)、每天睡眠时间<8h(OR=3.23，95%CI=1.44～7.27，P=0.01)均是儿童干眼发生的危险因素。

结论：近视防控门诊儿童干眼的患病率较高，应得到关注与重视，可通过改善行为习惯、控制视频终端电子产品使用时间等措施预防及减缓儿童干眼的发生。

METHODS:A total of 222 children aged 7-14 years in myopia prevention and control clinic from December 2021 to February 2022 were included. General data of included children were collected, assessing the prevalence of dry eye by the ocular surface disease index(OSDI)scale and Keratograph 5M, and analyzing risk factors for dry eye occurrence by Logistic regression model.

RESULTS:The prevalence of dry eye in children in myopia prevention and control clinic was 27.9%. Logistic Regression analysis showed that, allergic conjunctivitis(OR=2.31, 95%CI=1.12-4.78, P=0.02), refractive error(OR=5.57, 95%CI=2.40-12.94, P<0.01), use time of electronic >2h per day(OR=2.74, 95%CI=1.11-6.78, P=0.03), time of playing games >2h per day(OR=2.33, 95%CI=1.12-4.84, P=0.02), outdoor activity time ≤2h per day(OR=4.28, 95%CI=2.02-9.07, P<0.01)and sleep duration <8h per day(OR=3.23, 95%CI=1.44-7.27, P=0.01)were risk factors for dry eye among the children.

CONCLUSIONS:The prevalence of dry eye among children in myopia prevention and control clinic should be paid high attention. Therefore, improving behavior habits and controlling the use time of visual display terminal products to prevent and slow down the occurrence of dry eye in children.
