气象要素对南京市呼吸系统疾病的影响研究

摘要

Based on the daily meteorological data and daily respiratory system diseases data of Nanjing from 2007 to 2012,the relationship between numbers of patients and meteorological factors was analyzed to reveal the influences of meteorological conditions on respiratory system diseases by using the conventional statistic methods,which provide meteorological guidance of living and working for the local residents.Results show that a 1-2 days lagging effect between respiratory system diseases and meteorological factors,especially the factors of daily average temperature,daily maximum temperature and daily minimum temperature.The total number of patients increase significantly when the average temperature is below 0 ℃.The number of patients among the whole population and the elderly (＞65 years) significantly increase while the cold events occurs with the increasing rate of 35％ and 53％ and has a one-day lagging.However,the number of child patients (＜6 years) has no lagging and increases by more than two times.%利用2007-2012年南京市逐日气象资料和同期某三甲医院呼吸系统疾病逐日急诊和门诊就诊人数资料,采用常规统计方法,分析了主要气象要素与疾病就诊人数的关系,揭示了气象条件对人群呼吸系统疾病的影响程度,为当地居民防病养生提供气象指导.结果表明:呼吸系统疾病发病与气象要素之间存在1～2 d的滞后效应,且与日平均气温、日最高气温和日最低气温的相关最显著,尤其当平均气温低于0℃时,全人群就诊人数明显增加;此外,当寒潮过程发生时,全人群和老年人(＞65岁)就诊人数增加率分别为35％和53％,且表现出1d的滞后性;与之相比,儿童(＜6岁)就诊人数没有表现出滞后效应,寒潮结束当日,就诊人数增加了2倍以上.
