Analysis of Relationship between Emergency Incidence of Hypertension and Meteorological Conditions
Based on the emergency incidence data of hypertension in several grade A tertiary hospitals in Beijing from 2008 to 2012 and the meteorological and environmental data of the same period,the potential relationship between the incidence of hypertension and meteorological environmental conditions was explored.The results showed that:(1)The number of hypertensive emergency patients increased year by year,the ratio of male to female was 1.064∶1.000,and the number of middle-aged patients(45-65 years old)accounted for 40.36%of the total number of hypertensive emergency patients.(2)The number of hypertensive emergency patients had seasonal characteristics,which was autumn＞winter＞spring＞summer,and was negatively correlated with daily mean temperature,minimum/maximum temperature,vapor pressure and relative humidity,and positively correlated with daily mean pressure.(3)A nonlinear model was established and revealed that the risk of hypertension was highest in dry cold weather with daily minimum temperature＜10℃and vapor pressure＜5 hPa.The effect of low temperature below-10℃on the incidence of hypertension was immediacy,and the vapor pressure below 5 hPa had a lag effect on the incidence of hypertension.
