上海市霾期间PM_(2.5)、PM_(10)污染与呼吸科、儿呼吸科门诊人数的相关分析

Correlation Analysis Between the PM_(2.5),PM_(10) Which were Taken in the Hazy Day and the Number of Outpatient About Breathing Sections,Breathing Sections of Pediatrics in Shanghai

为了探讨上海市霾期间PM2.5、PM10污染与呼吸科、儿呼吸科日均门诊人数的相关性;对上海市6所大中型医院2009-01-01～2009-12-31期间医院呼吸科、儿呼吸科日门诊人数及霾天PM2.5、PM10的浓度数据运用广义相加泊松回归模型进行统计分析,并进行当日和滞后日的危险度评估.结果发现,在霾发生当日,PM10日均浓度每增加50μg/m3,呼吸科、儿呼吸科日均门诊人数分别增加3%和0.5%;PM2.5日均浓度每增加34μg/m3,呼吸科、儿呼吸科日均门诊人数分别增加3.2%和1.9%;同时PM2.5、PM10污染对门诊人数影响的滞后累积效应大于当日效应,且在霾污染暴发第6 d时累积效应达到最大化.从而推测,上海市霾期间PM2.5、PM10污染对医院呼吸科、儿呼吸科日均门诊人数具有一定影响.

In order to explore the correlation between the concentration of PM10,PM2.5 which were taken during the day of haze pollution and the average number of outpatient service、pediatrics.Based on the date with the number of pediatric、outpatient and the concentration of PM2.5,PM10which were taken form the haze days on 1 January 2009-December 31 in 6 hospital in shanghai such as xinhuan hospital,we analyzed the data and executed the risk evaluation.The results showed that： in the haze day,when the average concentration of PM10 increase 50 μg/m^3,the average number of the outpatient service and pediatric clinic increased 3% and 0.5%,when the average concentration of PM2.5 increase 34 μg/m^3,the average number of the outpatient service and pediatric clinic increased 1.9% and 3.2%,Also,the pollution of PM10 and PM2.5 has a larger cumulative effects on the number of outpatient service.And the accumulation effect will be To maximize after 6 days behind the haze pollution.Thus,PM2.5,PM10 which were taken during the haze of pollution in shanghai,has certain influence on the average number of outpatient service,pediatric clinic.
