A Preliminary Study on Warning of Allergic Diseases Caused by Pollen / 环境与健康杂志

ABSTRACT

Objective By discussing the relationship between allergic diseases caused by pollen,pollen density and meteorological factors,making out the warning for the allergic diseases caused by pollen,in order to provide a public service.Methods The data of meteorology from 2001 to 2005 of Tianjin,the pollen monitoring of the Weather Iron Tower Station day by day and the allergic patients whose skin tests were positive in Tianjin Municipal Chest Hospital and Tianjin Municipal Police Hospital were taken to statistical analysis on the rule of seasonal allergic diseases,the relationship between allergic diseases and pollen density and meteorological factors(such as vapor pressure and wind speed),and the prediction equations were obtained for allergic diseases caused by pollen.Results There was obviously positive correlation between the incidence rate of pollinosis(y),weighted pollen density(x11) and vapor pressure(x22) within twenty-days before the onset.The multiple correlation coefficient was 0.805 and the prediction equation was y =2.385+ 0.079 3x11 +3.507x22.Conclusion There is a close correlation between the incidence rate of pollinosis and pollen density.The allergic diseases caused by pollen are also affected by the change of air temperature,varieties of pollen and humidity.
