Teaching environment of primary middle and high schools in Suzhou during 2019 / 中国学校卫生

ABSTRACT

Objective@#To analyze the teaching environment of primary, middle and high schools in Suzhou, and to explore the relevance of students’ myopia with teaching environment, as well as the key problems in teaching environment.@*Methods@#1 253 classrooms in 204 schools rom 10 districts and counties in Suzhou were selected by proportionate stratified sampling. The qualified rate of each indices was described and the teaching environment by county, learning stage were compared by using chi-squared test. The Spearman test is used to explore correlations between myopia with monitoring indicators.@*Results@#The qualified rate of the distance from lamp to table was the highest (98.56%), while matching rate of student desk and chair was the lowest(0.96%). Minimum lamp table spacing, blackboard average illumination, reflectance from blackboard wall, classroom per capita area, classroom microclimate differed significantly in urban and rural (P<0.05); daylighting coefficient, reflectance from walls, average illumination of desktop and blackboard, classroom per capita area, and microclimate indicator were statistically different by learning stages(r=0.42,P<0.05). Prevalence of myopia correlated with the index of lighting.@*Conclusion@#Qualified desks and matched chairs, as well as the daylighting design in classroom should receive more attention in Suzhou. The findings lend support to identification of key health priorities and formulation of the localized health practice for health administrations.
