Association between sleep and poor vision in Chinese Han students aged 7–18 years

Abstract

Objective To analyze the relationship between sleep and poor vision of primary and middle school students aged 7–18 years, and to provide evidence for further student eye health promotion.

Methods Data was collected from the Chinese National Survey on Students’ Constitution and Health in 2014. A total of 173 555 primary and middle school students were examined with the 5 m standard visual acuity chart. Sleep, homework time, milk consumption and exercise duration were collected by questionnaire survey.

Results Only 5.60% of students aged 7–18 years had enough sleep, and the poor vision rate among students with insufficient sleep was higher than that of students with sufficient sleep (69.11% vs 67.76%), and the difference is statistically significant (χ ² = 7.87, P = 0.01). After adjusted for other related factors, it showed that students’ sleep was closely related to poor vision ( P<0.01), and adequate sleep was the protective factor of students’ poor vision ( OR = 0.92, 95% CI = 0.88–0.96).

Conclusion Adequate sleep is conducive to preventing the occurrence of poor vision of primary and secondary school students in China. We should take measures to ensure that students get enough sleep.

【摘要】 目的 分析中国汉族 7~ 18 岁中小学生睡眠情况与视力不良的关系, 为进一步促进学生视力健康提供依据。 方法 研究对象来自 2014 年全国学生体质与健康调研数据, 采用分层随机整群抽样法, 抽取全国 30 个省、自治区、直辖市 (港、澳、台、西藏除外）共 173 555 名汉族中小学生, 利用 5 m 标准视力表检査学生的裸眼视力, 利用问卷调査收集学生睡 眠情况及作业时间、喝奶情况、锻炼时长等。 结果 中国学生睡眠充足率仅为 5.60%, 睡眠不足的学生视力不良检出率 (69.11%) 髙于睡眠充足的学生 (67.76%), 差异有统计学意义 ( χ ²=7.87, P =0.01)。多因素 Logistic 回归分析显示, 在调整 其他相关因素后发现, 睡眠充足与学生视力不良呈负相关 ( OR = 0.92, 95% CI =0.88~0.96)。 结论 充足的睡眠有利于预防 中小学生视力不良的发生, 应采取相应措施保证学生睡眠充足。
