Abstract:
Objective To assess the effects of temperature and rainfall on the incidence of cardiovascular and cerebrovascular diseases (CVD) in Guiyang. Methods Using daily CVD incidence data and temperature and rainfall data in Guiyang City from September 2021 to August 2022, a distributed lag non-linear model was used to explore the nonlinear relationship between meteorological and environmental factors and CVD incidence. Results The risk of CVD was higher under cold (average, minimum, and maximum temperatures <2.1 ℃, 1.6 ℃, and 4.2 ℃, respectively) and hot (maximum temperature>32.5 ℃) effects, and the cumulative lag effect reached its maximum at 10 and 17 days, respectively. The risk of CVD increased sharply when there was a small diurnal temperature (<6.9 ℃), sudden drop in temperature (over 6.1 ℃), and heating (over 2.4 ℃ in 24 hours). The incidence risk of CVD was high when the daily rainfall exceeded 21.5 mm and the continuous rainy days exceed 5.7 days. The risk in rainstorm was 0.81 higher than that in heavy rain. Continuous absence of rain helped to prevent CVD patients from developing symptoms. Conclusion Meteorological environments such as hot and cold weather, dramatic change in temperature, significant rainfall and continuous rainfall have an impact on the incidence of CVD. It is necessary to consider the changes of the meteorological environment during the prevention and control of CVD.
