Abstract：Objective To understand the impact of daily mean temperature at different lag days on emergency risk of respiratory diseases in Urumqi. Methods We collected the data concerning the number of daily emergency ambulance dispatches due torespiratory diseases, meteorological and atmospheric pollutants in Urumqi from 2016 to 2018. Meteorological data included the daily mean temperature, relative humidity and average air pressure. Atmospheric pollution data included the mean daily concentration of PM2.5, PM10, SO2, NO2 and CO and the mean daily concentration of maximum 8-hour O3. The emergency data came from Urumqi Center for Disease Control and Prevention. The meteorological and atmospheric pollution data came from the six monitoring sites (including toll collection, railway bureau, the 31st middle school, monitoring stations, the 74th middle school and Midong District Environmental Protection Bureau) in the main urban areas of Urumqi. Distributed lag non-linear model was used to assess the relationship of daily mean temperature with the number of daily emergency ambulance dispatches due to respiratory diseases. Results An N-shaped relationship was found between daily mean temperature and emergency risk of respiratory diseases. When the temperature was relatively low, the risk of first aid due to respiratory diseases gradually decreased with the increase of lag days, and then increased. High temperatures had a protective effect against respiratory diseases. In a subgroup analysis, men were slightly more likely than women to be affected by respiratory diseases. People younger than 65 years of age were at greater risk of being affected by cold temperatures. Conclusion Low temperatures may increase the risk of first aid due to respiratory diseases, while high temperatures have protective effects against respiratory diseases. The sensitivities of cold and heat effects vary with different ages and gender.
