收集了北京市某三级甲等医院2009年2月-2010年5月的发热门诊急诊就诊资料32 954例,在对疾病资料进行平滑处理的基础上,分季节研究就诊人次与各主要气象要素的滞后相关性,并提取就诊高峰日,对其前后3 d主要气象要素的变化趋势进行分析.结果表明,发热门诊就诊人数春秋季多、夏冬季少;不同季节影响发热的气象要素各有特点:春季,升高的气温、降低的气压、较小的湿度会造成发热性疾病就诊人数的增加,气温、气压的影响具有明显的滞后性;夏季,伴随降温的阴(雨)天后会迎来就诊人数的小幅增加;秋季,就诊人数会随着气温降低、气压升高和湿度减小而增加,与春季相反的关系体现人体对季节转换的适应过程,需要特别注意“低温-干燥”的天气;冬季,高气压代表晴朗干燥的天气,会增加北京市发热性疾病的发病.气象条件与发热门诊就诊人数关系密切,且不同季节作用的天气类型各有特点.
A total of 32 954 cases of outpatient and emergency department visits were collected from a tertiary level Hospitals in Beijing from February 2009 to May 2010. Based on the smoothing of the disease data, sub-seasons of study visits and major meteorological elements , And analyzed the trend of the main meteorological elements before and after 3 d.The results showed that the number of outpatients with fever in spring and autumn was more than in summer and winter and the meteorological elements that affected the fever in different seasons were different : In spring, the increased temperature, the reduced pressure and the smaller humidity will cause an increase in the number of fever-related diseases. The effects of temperature and air pressure have obvious hysteresis. In summer, the rainy days with the cooling will be ushered in In the fall, the number of visits increased with the decrease of temperature, the increase of air pressure and the decrease of humidity. The opposite relationship with the spring reflected the process of human body’s adaptation to seasonal changes, and special attention should be paid to “low temperature-drying” Of the weather; winter, high pressure on behalf of sunny and dry weather, will increase the incidence of febrile diseases in Beijing. Meteorological conditions and the number of outpatients fever clinics close, and different seasons Weather type with its own characteristics.
