Impact of environmental temperature on risk of non accidental deaths of the crowd in Weifang City
Objective To understand the relationship between environmental temperature and deaths in Weifang City from 2010 to 2022 and the impact of unfavorable environmental temperatures on the mortality.Methods The meteorological data and population mortality data from Weifang City during 2010-2022 were collected,and a time series analysis was conducted to analyze the impact of environmental temperature on the risk of non-accidental deaths in Weifang City.Results A total of 767 480 non-accidental deaths occurred in Weifang City from 2010 to 2022,including cerebrovascular diseases and 72 036 and 423 939 deaths from cardiovascular deaths from chronic respiratory diseases.The lowest death temperature in Weifang City from 2010 to 2022 was 22.1 ℃.The cumulative effect value of the risk of death from extremely low temperatures was 1.285(95％CI:1.168-1.415),and the cumulative effect value of the risk of death from extremely high temperatures was 1.141(95％CI:1.076-1.209).For every 1 ℃ increase in temperature,the excess risk of death was 0.91％(95％CI:0.80％-1.02％).The attributable percentage of temperature to total deaths was 9.13％(95％CI:5.43％-12.92％),with the attributable percentage of low temperatures higher than that of high temperatures.The mortality effect of men affected by temperature is lower than that of women,and the mortality effect of cardiovascular and chronic respiratory diseases affected by temperature was higher than non accidental total mortality.Conclusion Both high and low temperatures can increase the risk of death,with the impact of low temperatures lasting longer than that of high temperatures.More attention should be paid to susceptible populations with chronic respiratory diseases and cardiovascular and cerebrovascular diseases.
