【摘要】：目的了解四川省中小学生视力现况及其影响因素,为中小学生视力不良防控提供科学依据。方法采用分层随机抽样的方法,于2015年收集四川省14 306名7~18岁中小学生视力数据。分析不同年龄、性别、地区的学生视力的差异以及可能的影响因素。结果学生视力不良率为52.3%,平均视力为(4.79±0.37)。不同年龄组学生视力不良率与平均视力差异均有统计学意义(P值均0.01);女生视力不良率(55.8%)高于男生(48.8%)(χ~2=70.190,P0.01),平均视力(4.77)低于男生(4.82)(t=7.143,P0.01);城市学生视力不良率(59.6%)高于农村学生(44.5%)(χ~2=326.403,P0.01),平均视力(4.74)低于农村学生(4.85)(t=18.047,P0.01)。10~12,12~13,14~15,15~16,17~18岁年龄段学生平均视角扩大速度约为7%~23%。结论随着学生年龄增长,视力不良率不断升高,伴随视力不断下降;小学高年级、初中三年级、高中三年级学生视力下降幅度较大,需重点关注。
[Abstract]:Objective to investigate the present situation and influencing factors of visual acuity of primary and middle school students in Sichuan province, and to provide scientific basis for prevention and control of visual impairment among primary and middle school students. Methods the visual acuity data of 14 306 primary and middle school students aged 7 years in Sichuan province were collected by stratified random sampling in 2015. Analyze the visual acuity of students of different age, sex, region and possible influencing factors. Results the rate of visual acuity was 52.3%, and the average visual acuity was 4.79 卤0.37%. There were significant differences in visual acuity rate and average visual acuity in different age groups (P < 0.01), and the rate of visual acuity in girls (55.8%) was higher than that in boys (蠂 2% 70.190 P 0.01, average visual acuity 4.77), which was lower than that in boys (4.82%), and the rate of urban students' visual acuity was 59.6%, which was higher than that of rural students (326.403% P 0.01). The average visual acuity was 4.74) lower than that of the rural students (P 0.01, P 0.01, P 0.01, P 0.01). The average speed of visual angle expansion of the students in the age group of 18 years old was about 7. 23230.The average visual acuity of the students in the age group of 18 years old was about 7 / 23233.The average visual acuity was 4.74). Conclusion with the increase of students' age, the rate of visual acuity is increasing, accompanied by the decline of visual acuity, and the decline of eyesight in the senior grade, the third grade of junior middle school and the third grade of senior middle school is quite large, which should be paid more attention to.
