摘要
目的了解气温对南京市居民呼吸系统疾病死亡的影响特点,以采取有针对性的预防措施,减少因气温变化导致的呼吸系统疾病的死亡。方法回顾性采集南京市2003—2009年病伤死因年报表中因呼吸系统疾病死亡的居民死亡资料和对应年度气象资料,分析气温与呼吸系统疾病月死亡人数的相关性,再以月死亡人数为因变量,各气象因子为自变量进行线性回归分析。结果月平均气温、月平均最高气温、月平均最低气温与呼吸系统疾病月死亡人数均呈负相关,其中月死亡人数与月平均最高气温负关联性最强(r=-0.796,P<0.01);65岁及以上的老年人群与气象因素的相关性更为显著;月死亡人数随月平均气温的升高死亡人数逐渐降低(β=-0.709,P<0.01)。结论气温越低,呼吸系统疾病死亡人数越多。
[ Objective ] To investigate the impacts of air temperature on the mortality of respiratory diseases in Nanjing City, so as to adopt targeted prevention measures to reduce the mortality of respiratory diseases due to temperature change. [ Methods ] The death data of respiratory diseases among residents in Nanjing City from 2003-1009 and corresponding meteorological data were collected for retrospective analysis of correlation. The monthly deaths were taken as dependent variable, and meteorological factors as inde- pendent variable to perform linear regression analysis. [ Results ] Monthly average temperature, monthly mean maximum tempera- ture and monthly mean minimum temperature were negatively correlated with monthly deaths of respiratory diseases, especially for monthly mean maximum temperature （ r = - 0. 796, P 〈 0.01 ）. The correlation between meteorological factors and people aged over 65 years was significantly. The monthly deaths decreased with the increasing air temperature （β=- 0. 709, P 〈 0. 01 ）. [ Conclusion ] The mortality of respiratory diseases is negatively correlated with air temperature.
