Abstract:
Objective To explore the impact of temperature and environmental factors on the risk of deaths from cardiovascular and cerebrovascular diseases (CVD) in Wuhan during the course of high temperature. Methods The daily CVD death data and meteorological and atmospheric pollutant concentration data during the high temperature process in Wuhan from 2014 to 2019 were collected. The generalized additive models (GAM) were used to obtain the characteristics of meteorological factors, atmospheric pollutant concentrations, high impact factors and thresholds affecting the relative risk of CVD death. Results The analysis results showed that: (1) When the maximum temperature reached 36.7°C and the lowest temperature reached 25.3°C, the relative risk of CVD death increased significantly; (2) The risk of CVD death during the first high temperature process was the largest, and the average CVD excess mortality rate during the first high temperature process from 2014 to 2019 reached 21.7%; and (3) The average temperature, maximum temperature and PM10 during the course of high temperature were important environmental factors that increased the risk of CVD deaths, and the relative risks were 1.14 (95% confidence interval (95% CI): 1.11-1.17), 1.11 (95% confidence interval (95% CI): 1.08-1.15, and 1.06 (95% confidence interval (95% CI): 1.02-1.09), respectively. Conclusion Temperature and PM10 are important environmental factors that increase the risk of death from CVD during the high temperature process in Wuhan from 2014 to 2019, with the first annual high temperature process having the greatest impact on the risk of CVD death.
