Effects of air pressure,humidity,wind and sunshine on the incidence of cardiovascular and cerebrovascular diseases in Guiyang
Objective To explore the effects of air pressure,humidity,wind,and sunshine on the incidence of cardiovascular and cerebrovascular diseases(CVD)in Guiyang,and to provide reference for the prevention of CVD.Methods Using CVD incidence data from September 2021 to August 2022 in Guiyang City and meteorological data including average air pressure,average humidity,wind,and sunshine during the same period,the effects of meteorological factors on CVD incidence were explored and the importance of each factor was analyzed.Results When air pressure was below 868 hPa,above 887 hPa,or between 877 and 883 hPa,and when air pressure dropped less than 5.3 hPa within 24 hours,there was a higher risk of CVD.When the humidity was above 81％,the wind speed was small(＜1.2 m/s)or high(＞4m/s),and there was less sunlight(less than 3 hours),the risk of CVD was higher.Low humidity(＜60％)was not conducive to the onset of CVD.There were highest risks at lag 5～14 days and 4-25 days for high pressure and low sunlight,respectively.When the relative humidity was saturated,there was an immediate effect.When the wind speed was low and high,the immediate effect and hysteresis effects were significant.Among the above meteorological factors,the impact of pressure change between neighboring days and high or low atmospheric pressure on the incidence of CVD was the most significant,while the impact of sunlight and humidity was the weakest.The impact of diurnal variations in wind and atmospheric pressure was not clear.Conclusion The impact of air pressure on the incidence of CVD does not exhibit a simple linear relationship.The risk of CVD is high in high humidity,low light,and moderate or strong winds.It is necessary to fully consider changes in meteorological factors for CVD prevention and control.
