【摘要】:为探究气象环境条件对消化系统疾病的影响,结合分布滞后非线性模型与广义相加模型,分析了2009~2011年气象环境要素与北京市消化系统疾病急诊人数的暴露-反应关系.结果显示,气温对消化系统疾病的影响主要体现为"高温效应",高于25℃的气温其危险度RR随气温升高而增加,且滞后效应能达到10d以上.较为极端的湿度(RH10%或RH90%)会显著增加消化系统疾病的发病,并有持久的作用,其与高温结合会形成"高温低湿"和"高温高湿"2种让人不适的情况.0~2m/s的风速在短的滞后期(5d)最能增加发病危险性.而3~4m/s的风速对疾病的危险性小,说明适度的风速不影响健康.浓度高于200μg/m~3的PM_(10)和浓度高于70μg/m~3的NO_2具有即时的危险性(5d内显著);而较高浓度(55μg/m3)的SO_2滞后一定时期后效应更加明显.
[Abstract]:In order to investigate the influence of meteorological environmental conditions on digestive system diseases, the relationship between exposure and response of meteorological environmental elements and emergency population of digestive system diseases in Beijing from 2009 to 2011 was analyzed by combining the nonlinear model of distribution lag with the generalized additive model. The results showed that the effect of temperature on digestive system diseases was mainly "high temperature effect". The RR of temperature above 25 鈩,
