Abstract：Objective To analyze the current situation of teaching environment hygiene in primary and middle schools in Hunan Province in 2021, and to provide a basis and suggestions for policy-making towards classroom environment improvement and promoting students’ health. Methods Six hundred and sixty primary and secondary schools were selected in 123 counties or cities of Hunan Province in 2021, and 6 classrooms were chosen in each school. Per capita area, distribution of desks and chairs, blackboard size, blackboard reflection ratio, illumination and noise in the classrooms were inspected on the spot, and then the status of teaching environment hygiene was evaluated. Results The qualified rates of per capita classroom area, distribution of desks and chairs, blackboard size, blackboard reflection ratio, average illumination of blackboards, evenness of illumination of blackboards, average illumination of desks, evenness of illumination of desks and noise in the primary and secondary schools in Hunan Province in 2021 were 29.6%, 12.7%, 71.8%, 41.0%, 26.8%, 80.1%, 51.1%, 58.5% and 45.8% respectively. The qualified rates of per capita classroom area, average illumination of blackboards, average illumination of desks and evenness of illumination of desks in urban schools were higher than those in suburban schools (35.5% vs. 25.9%, 33.4% vs. 22.6%, 53.2% vs. 49.7%, 61.7% vs. 56.5%). The qualified rates of blackboard size, blackboard reflection ratio and evenness of illumination of blackboards in suburban schools were higher than those in urban schools (75.4% vs. 66.0%, 43.0% vs. 37.8%, 83.1% vs. 75.3%), showing statistically significant differences. The qualified rates of blackboard size, evenness of illumination of blackboards andevenness of illumination of desks in public schools were higher than those in private schools (73.0% vs. 52.8%, 80.4% vs. 75.2%, 59.0% vs. 51.2%), while the qualified rates of per capita classroom area and noise in private schools were higher thanthose in public schools (38.2% vs. 29.1%, 52.4% vs. 45.3%), with statistically significant differences. From theaspects of areas with poor economic status to areas with good economic status, the qualified rates of per capita classroom area, distribution of desks and chairs, average illumination of blackboards and average illumination of desks showed upward trends, while thequalified rates of blackboard size, blackboard reflection ratio and evenness of illumination of blackboards showed downward trends, showing statistically significant differences. With the education stage from low to high, per capita classroom area, average illumination of blackboards and noise showed increasing trends, while the qualified rate of blackboard size presented a decreasing trend, showing statistically significant differences. Conclusion The overall situation of teaching environment hygiene of the primary and secondary schools in Hunan Province is not optimistic, and the distribution among different economic areas, education stages and schooltypesis not balanced. It is necessary to further strengthen the improvement of teaching environment so as to promote the students’ health.
