摘要
目的了解天津市中小学校教室照明情况及其与学生视力的关系,为中小学生视力保护提供依据和理论支持。方法采用分层整群随机抽样的方法,选取天津市有代表性的3所学校中共计67间教室,进行教室照明检测,并对所检测教室的1 494名学生进行视力不良筛查。采用秩相关初步分析教室照明指标与班级平均视力的关系。结果课桌面和黑板的平均照度合格率较高,分别为85.07%和70.15%;黑板照度均匀度合格率较低,仅有52.24%。小学教室课桌面平均照度均高于初中和高中(P值均<0.01),但初、高中间差异无统计学意义(P=0.792)。不同年级组间的视力不良率差异有统计学意义(χ~2=298.01,P<0.01),且随着年级升高,视力不良率增加。仅在小学中发现班级平均视力与课桌面平均照度间存在正相关(r=0.688,P<0.01),初、高中未发现班级平均视力与教室照明指标的相关性(P值均>0.05)。结论教室光环境可能更易对小学生的视力发育产生影响。应重视教室照明现状,为中小学生营造良好的教室照明环境。
Objective To examine the association between classroom illumination and students＇ vision, and to provide theoretical basis and support for prevention of students＇ vision. Methods A total of 67 classrooms in three representative schools in Tianjin were selected by stratified cluster random sampling method. The examination of classroom illumination was carried out, and 1 494 students in the classroom were screened for poor eyesight. The rank correlation was used to analyze the relationship between classroom lighting and students~ average visual acuity in class preliminarily. Results The qualification rate of average illumination of desk and blackboard were relatively higher, which were 85.07% and 70.15%, respectively. However, the qualification rate of the uniformity of blackboard illumination was only 52.24%. The average illumination of the desk in the primary classroom was higher than that of the junior middle school and the high school （P〈0.01）, but there was no significantly statistical difference between jun- ior high school and high school （ P = 0.792）. There was only a positive correlation between the average visual acuity of the class and the average illumination of the desk （ r = 0.688, P〈0.01） in primary school. No correlation was found between the average visual an- ity of the class average illumination in middle and high schools（P〈0.05）. Conclusion The light environment of classroom may be more likely to have an impact on pupils＇ visual acuity. Schools and other relevant departments should pay attention to the status of classroom lighting, and create a qualified classroom lighting environment for the primary .and secondary students.
