不同地区慢性阻塞性肺病与气象因子相关性分析

为探讨不同地区慢性阻塞性肺病(COPD)患者发病与气象因子的关系,文章按月收集统计北京、上海、杭州、广州和南宁5个地区的全国监测中医医院2003年1月至2004年12月主要以COPD入院诊断的患者资料及同期的气象因子,做出COPD发病率的月际分布及地区差异,结果显示发病率华北地区高、华南地区低的特点十分明显。分析了COPD的月发病率与各气象因子相关性,冬季温度低、气压高与COPD的高发病率相对应;而夏季与当地人群对7、8月闷热天气的适应能力有关,相对湿度在夏季对COPD发病率的上升具有很好的指示意义。

Correlation Analysis between Chronic Obstructive Pulmonary Disease and Meteorological Factors in Different Areas

In order to discus the relationship between the incidence of Chronic Obstructive Pulmonary Disease(COPD)and meteorological factors in different areas across China,the month-to-month data of COPD suffers treated in hospital,the data from the logs of the hospitals in the China Monitoring Traditional-medical-treatment Hospital System from January 2003 to December 2004 in Shanghai,Beijing,Hangzhou,Guangzhou and Nanning,and the corresponding-period meteorological data are collected and analyzed.The seasonal distribution and regional diversity of the incidence of COPD are presented.Obviously North China has a high incidence rate,and South China has a low incidence.The correlation coefficient between the monthly incidence of COPD and meteorological factors are analyzed.The high incidence of COPD in winter corresponds with low temperature and high pressure,but the incidence in summer is related to the adaptation of local people to hot and humid weather.Relative humidity in summer has good indicative significance to the incidence of COPD.
