沙尘暴对呼吸及循环系统疾病日门诊量的影响

对沙尘天气频发区甘肃省武威市的7所大、中型医院在2004、2005年沙尘天气高发时段(3月1日～5月31日)的呼吸系统和循环系统每日门诊人数进行了调查,采用半参数广义相加模型(GAM),在排除了医院日门诊量的长期趋势、大气污染因素、气象因素、日历效应等因素之后,分别对每年进行分析.结果表明,沙尘暴和扬沙天气与呼吸、循环系统疾病日门诊人数的增加有联系,且均表现为滞后效应,其影响程度为沙尘暴大于扬沙天气,沙尘暴和扬沙天气对健康的影响因不同年份而不同,表明沙尘天气对健康的影响受多种因素的影响.沙尘暴对健康的影响有性别差异.

The influence of dust storms on daily respiratory and circulatory outpatient number

The each daily outpatient number of respiratory and circulatory systems in dust weather highly generated period (Month 1st~May 31st) in 2004, 2005 years in 7 large and middle type hospitals of Wuwei City of Gansu Province was investigated. Adopting semi-parametric generalized additive model (GAM), after removing long time trend of hospital daily outpatient service amount, factors of atmospheric pollution, meteorolagy and calendar effect, analysis was made in each year respectively. Dust storms and blowing sand weather were related with the increase of daily outpatient number of male and female respiratory and circulatory diseases, and all were delayed effects; its influence degree was dust storms greater than blowing sand weather.
