Big Data Analysis And Research On The Impact Of Air Pollution On Children's Respiratory System Outpatient Visit

Air pollution is a global public environmental issue,which has a far-reaching effects on the global population health.More and more attention has been paid to the effects of air pollution on death,respiratory system and circulatory system.The pediatric respiratory system is more sensitive to air pollution,so we focuse on the effects of air pollution on outpatient amount of pediatric respiratory system in Linyi.This dissertation collected six air pollutants data(PM_2.5,PM₁₀,SO₂,NO₂,CO,O₃)、the meteorological data（temperature,relative humidity）and the pediatric respiratory system data from two Grade 3,Class A hospital in Linyi during 2021.Firstly cteat database and make descriptive analysis,create a time series diagram to observe the correlation and trend of each index.After controlling other mixed factors affecting outpatient amount,a GAM of air pollutants and outpatient amount of pediatric respiratory system was established.Classified outpatient date by gender,age and disease diagnosis.Classified date by heating season and non-heating season.Single-pollutant model and double-pollutant model were established to quantitatively analyze the effects of air pollution on outpatient amount of pediatric respiratory system in Linyi.During the study period,two hospitals received 761265 children with respiratory system diseases.Some conclusions are as follows:1)The regularity of pediatric respiratory system treatment showed a wavy trend and an overall upward trend.The number of winter is significantly higher than other seasons,and the heating season is higher than the non-heating season.Emergency children accounted for 62.97%of the total outpatient amount,and the proportion of emergency was high.2)PM_2.5,PM₁₀,SO₂ and NO₂ all had effects on the outpatient amount of pediatric respiratory system.Except for PM₁₀,the cumulative lag effect is greater than the single-day delayed effect.3)The optimal effect of PM_2.5,PM₁₀,SO₂,NO₂ on the outpatient amount of pediatric respiratory system appeared in lag05,lag0,lag05,lag05.At this time,when each pollutant increased by 10ug·m^-3,the outpatient amount of pediatric respiratory system increased by0.96%（95%CI:0.87%～1.13%）,0.26%（95%CI:0.18%～0.35%）,2.72%（95%CI:1.78%～3.66%）,2.67%（95%CI:2.27%～3.07%）.4)PM_2.5 has a greater effects on the outpatient amuont of pediatric respiratory system than PM₁₀ in atmospheric particulate matter.5)The effects of air pollutants on the outpatient amuont of pediatric respiratory system in heating season is greater than that in non-heating season.6)The effects of gaseous pollutants on the outpatient amuont of pediatric respiratory system is greater than that of atmospheric particulate matter.7)The double-pollutant model suggests that the interaction between atmospheric particulate matter and gaseous pollutants will reduce the effects on the outpatient amuont of pediatric respiratory system.The interaction of gaseous pollutants has the greatest effect on the outpatient amuont of pediatric respiratory system.
