Abstract

BACKGROUND

This study aimed at investigating the relationship between the weekend catch-up outdoor duration (WCOD) and prevalence of myopia among students in China.

METHODS

This cross-sectional study recruited participants in 107 schools (six cities, 30 districts) from China from May to June 2021. Demographic characteristics (age, grade, sex, ethnicity, BMI, resident, and parents' myopia), optically habits (bad writing habits, working/studying time per day, continuous working/studying time per day, and screen time per day) and outdoor duration (weekday and weekend) were obtained from questionnaire. WCOD was defined as outdoor time 1 h longer on weekends than on weekdays. Spherical equivalent (SE) of refractive error were measured with non-cycloplegic refraction. Adjusted multivariate logistic regression analysis was performed to evaluate the relationship between WCOD and prevalence of myopia.

RESULTS

Students with myopia had shorter WCOD compared with those without myopia (P < 0.001). Adjusted multivariate logistic regression analyses showed negative associations between WCOD and prevalence of myopia in Chinese students, especially in students with WCOD of 2-3 h (OR = 0.577, P < 0.001) and 3-4 h (OR = 0.571, P = 0.004) when the weekday outdoor duration was 0.5-1 h, as well as students with WCOD of 2-3 h (OR = 0.614, P = 0.003) when the weekday outdoor duration was 1-2 h. Similar results were observed in students with high myopia. Students with high myopia had shorter WCOD compared with those without high myopia (P = 0.001). Negative associations between WCOD and prevalence of high myopia were significant in students with WCOD of 1-2 h when the weekday outdoor duration was < 0.5 h (OR = 0.585, P = 0.007) and 0.5-1 h (OR = 0.537, P = 0.018).

CONCLUSION

Our study, for the first time, reported that a WCOD have a potential to reduce the prevalence of myopia and high myopia in Chinese students.

摘要

背景

本研究旨在探讨中国学生周末补觉户外活动时间（WCOD）与近视患病率之间的关系。

方法

本横断面研究于 2021 年 5 月至 6 月在中国 6 个城市 30 个区的 107 所学校招募参与者。从问卷中获取人口统计学特征（年龄、年级、性别、民族、BMI、居民和父母近视）、光学习惯（不良书写习惯、每天工作/学习时间、每天连续工作/学习时间和每天屏幕时间）和户外活动时间（工作日和周末）。WCOD 定义为周末比工作日户外活动时间长 1 小时。使用非睫状肌麻痹验光测量等效球镜（SE）。采用多变量逻辑回归分析评估 WCOD 与近视患病率之间的关系。

结果

与无近视者相比，近视学生的 WCOD 更短（P<0.001）。多变量逻辑回归分析表明，在中国学生中，WCOD 与近视患病率呈负相关，尤其是在工作日户外活动时间为 0.5-1 小时时，WCOD 为 2-3 小时（OR=0.577，P<0.001）和 3-4 小时（OR=0.571，P=0.004）的学生，以及工作日户外活动时间为 1-2 小时时，WCOD 为 2-3 小时（OR=0.614，P=0.003）的学生。在高度近视的学生中也观察到类似的结果。与无高度近视者相比，高度近视学生的 WCOD 更短（P=0.001）。在工作日户外活动时间<0.5 小时（OR=0.585，P=0.007）和 0.5-1 小时（OR=0.537，P=0.018）时，WCOD 与高度近视患病率呈负相关，在学生中具有统计学意义。
