背景：Covid-19大流行限制了儿童和青少年进行正常的日常活动，如户外玩耍和上学。新冠肺炎大流行期间，近视的发病率和流行率有所上升。本研究旨在调查和评估新冠肺炎大流行期间居家隔离对重庆市儿童和青少年近视进展的影响。方法：采用分层抽样法进行调查。从2019年全国学生体质与健康调查数据库中随机抽取样本，将其视功能和屈光数据与2020年进行比较。采用包括数字屏幕暴露在内的视力相关行为问卷调查眼睛参数与眼睛健康相关行为的相关性。结果：2020年和2019年分别招收1733名和1728名学生。2020年近视学生比例为55.02%，高于2019年的44.62%。2020年平均未矫正视力（UCVA, LogMAR, 0.35±0.42）高于2019年（0.27±0.36,P < 0.001）。2020年平均球面等效（SE）折射（- 1.94±2.13 D）低于2019年（- 1.64±5.49 D, P < 0.001）。对于使用数字设备进行在线课程的学生，电视组的平均SE（- 1.10±1.49 D）优于电脑组（- 2.03±2.37 D, P = 0.0017）和手机组（- 2.02±2.09 D, P = 0.0028）。在线课程的平均时长（r = - 0.27, P < 0.0001）、每天在线课程的次数（r = - 0.33, P < 0.0001）、数字屏幕暴露时间（r = - 0.20, P < 0.0001）与SE呈负相关，平均户外活动时间（r = 0.20, P < 0.0001）与SE呈正相关。结论：新冠肺炎大流行期间，重庆市儿童青少年近视加重与数字屏幕暴露增加有关。为在线上课提供合适的数字设备，提倡户外活动，预防近视大流行。
Background: The Covid-19 pandemic restricts children and adolescents from doing normal daily activities such as playing outdoors and going to school. The incidence and prevalence of myopia have increased during the COVID-19 pandemic. The aim of this study was to investigate and evaluate the impact of the home confinement during the COVID-19 pandemic on the progression of myopia among children and adolescents in Chongqing, China. Methods: The survey was conducted by using stratified samplings. Samples were randomly selected from the 2019 National Student Physique and Health Survey database, and their visual function and refractive data were compared with those in 2020. Vision-related behavior questionnaire including digital screen exposure was applied to investigate the correlation between eye parameter and eye health-related behavior. Results: A total of 1,733 and 1,728 students were enrolled in 2020 and 2019, respectively. The percentage of myopia students was 55.02% in 2020, which was higher than that in 2019 (44.62%). The mean uncorrected visual acuity (UCVA, LogMAR, 0.35 ± 0.42) in 2020 was higher than that in 2019 (0.27 ± 0.36, P < 0.001). The mean spherical equivalent (SE) refraction (−1.94 ± 2.13 D) in 2020 was lower than that in 2019 (−1.64 ± 5.49 D, P < 0.001). For students who used digital devices for online courses, the mean SE in the television group (−1.10 ± 1.49 D) was better than that in the computer group (−2.03 ± 2.37 D, P = 0.0017) and in the cell phone group (−2.02 ± 2.09 D, P = 0.0028). The average duration of online classes (r = −0.27, P < 0.0001), the number of online classes per day (r = −0.33, P < 0.0001), as well as digital screen exposure time (r = −0.20, P < 0.0001) were negatively correlated with SE, and the average time of outdoor activity (r = 0.20, P < 0.0001) was positively correlated with SE. Conclusions: Increased digital screen exposure contributes to myopic progression in children and adolescents of Chongqing during the COVID-19 pandemic. Suitable digital devices should be provided for online classes and outdoor activity should be advocated to prevent myopic pandemic.
