猝死与气象条件的关系

通过调查1999年1～12月上海市医疗救护中心急救的839例院外猝死病例，并与同期气象资料进行分析，发现院外猝死男性多于女性，高发年龄为60～84岁，院外猝死在年内的高峰期为冬季，在昼夜中的高峰点为早晨07时，既往有心血管病史是院外猝死的主要原因。总猝死数与相对湿度、平均气压呈正相关，与最低气温、平均气温呈负相关，心血管猝死数除与以上气象要素相关外，还与气压变化、最低气温变化、日照时数变化等呈正相关。冠心病和其他心脏病与平均风速呈负相关，高血压病与平均气压呈正相关。

THE RELATIONSHIP BETWEEN PREHOSPITAL SUDDEN DEATH AND METEOROLOGICAL VARIATION

cases of prehospital sudden death patients who received prehospital emergency medical care provided by the Shanghai Medical Emergency Center from January to December in 1999 are collected. The seansonality of Prehospital sudden death and its relationship between weather and climate are analyzed in order to decrease the sudden death related to weather change. The results show that 70.44% of the patients had a history of diseases before sudden death, high sudden death incidence happens in the age group of 60-80 years old that account for 64.48% of all patients. The male patients are more than the females. The incidence rate of prehospital sudden death patient is the highest in winter and the peak happens at 07:00 am in a day. There is a positive relationship between the total of sudden death and the variation of relative humidity and mean air pressure,and a negative relationship with minimum temperature and mean temperature. The cardiovascular-related sudden death, beside the above factors,is a positive relationship with the changes of the air pressure, the minimum temperature,and the radiation hours etc. Also, there is a negative relationship between coronary heart disease, other heart disease and mean wind velocity, and there is a positive relationship between hypertension and mean air pressure.
