Abstract: Objective To understand and analyze the status and trend of health management of teaching environment and living facilities in primary and secondary schools in Tianjin in recent three years,so as to provide basic data for improving school environmental conditions and doing better in school health supervision. Methods The stratified random sampling method was used to respectively select seven and five schools from six urban areas and 10 suburban areas of Tianjin during September-October each year from 2019 to 2021. The classroom health indicators were tested and evaluated according to relevant standards,and the health conditions of living facilities were investigated on the spot. Results In the past three years,the proportion of water purifiers or direct drinking water provided by primary and secondary schools in Tianjin reached 80%,which was higher than that of other drinking water methods,but there was not statistically significant difference between different years（P>0.05）. The construction of sanitary toilets in schools was in good condition,and the proportion of all equipped with soap has increased significantly,from 57.6% in 2019 to 93.3%. The uniformity of illuminance of desk surface and the qualified rate of noise showed an upward trend （χ²_trend=48.79,7.46,both P<0.01）,the qualified rate of classroom per capita area showed a downward trend（χ²_trend=25.54,P<0.01）. Conclusion In recent three years,the health management status of teaching environment and living facilities in primary and secondary schools in Tianjin has been improved,but further improvement is still needed.
