The purpose of this survey was to explore the prevalence of reduced visual acuity and its associated factors among school students in Shenyang in 2016.
This was a cross-sectional study using data from the Ministry of Education' Student Physical Fitness (MESPF) monitoring in 2016. A total of 13,642 students aged 9-18 years were surveyed in Shenyang. The unaided distance visual acuity was measured, and questionnaire on lifestyle behaviors that may affect visual acuity was investigated among students. The prevalence of reduced visual acuity and its associated factors were analyzed.
The average prevalence of reduced visual acuity among students aged 9-18 years was 65.8%, and severe reduced visual acuity was main (42.9%), and there were statistical effect of age, gender, and region on the prevalence of reduced visual acuity. Binary and multi variable logistic regression results revealed that students sleeping <8 h, homework hours ⩾1 h, and parental myopia had an increased risk of reduced visual acuity.
Sleep time <8 h and homework time ⩾1 h may be associated with reduced visual acuity among students in Shenyang. Therefore, it is benefit for student to get enough sleep and decreasing studying time in order to prevent and reduce poor vision.
本次调查旨在探究2016年沈阳市在校学生视力下降的患病率及其相关因素。
这是一项横断面研究，采用了2016年教育部学生体质健康监测的数据。在沈阳共调查了13642名9至18岁的学生。测量了裸眼远视力，并对学生进行了可能影响视力的生活方式行为问卷调查。分析了视力下降的患病率及其相关因素。
9至18岁学生视力下降的平均患病率为65.8%，重度视力下降为主（42.9%），年龄、性别和地区对视力下降患病率有统计学影响。二元和多变量逻辑回归结果显示，睡眠时间<8小时、作业时间≥1小时以及父母近视的学生视力下降风险增加。
睡眠时间<8小时和作业时间≥1小时可能与沈阳市学生视力下降有关。因此，为预防和减少视力不良，学生保证充足睡眠并减少学习时间是有益的。
