鸽舍气溶胶与饲鸽者肺功能变化相关性分析

Correlation of Environmental Aerosols and Changes in Pulmonary Function of Pigeon Breeders

目的探讨鸽舍气溶胶的大小和浓度对饲鸽者肺功能产生的影响。方法2021年12月~2022年1月从新疆维吾尔自治区吐鲁番市3个村庄居家饲养环境随机抽取的150位饲鸽者纳入接触组,同村未接触鸽子的健康体检者150例纳入对照组,详细询问和记录研究对象的相关信息,完善肺功能检查,并对周围环境气溶胶的浓度及大小进行了检测,分析不同浓度及大小的鸽舍气溶胶对饲鸽者肺功能(FEV 1、FVC、FEV 1%、FVC%、FEV 1/FVC)产生的影响,并分析肺功能与饲养鸽子年限、饲养数量、每日接触时间之间的相关性。结果接触组鸽舍气溶胶浓度高于对照组,接触组与对照组肺功能进行比较,可发现接触组FVC、FEV 1%、FVC%等肺功能指标均低于对照组,且组间比较差异有统计学意义(P<0.05);气溶胶浓度与FEV 1、FVC、FEV 1%、FVC%、FEV 1/FVC等肺功能指标呈负相关,差异有统计学意义(P<0.05)。每日和鸽子接触时间与肺功能各指标呈负相关,差异有统计学意义。饲养年限与FEV 1呈负相关,差异有统计学意义。结论鸽舍气溶胶浓度越高,饲养年限、每日与鸽子接触时间越长,饲鸽者肺功能相关指标下降越明显。

Objective To investigate the effects of the size and concentration of loft aerosols on the lung function of pigeon breeders.Methods From December 2021 to January 2022,a total of 150 pigeon breeders were randomly selected from three subordinate villages in Turpan,Xinjiang,from the greenhouse raising environment and the home raising environment to be included in the contact group,and 150healthy people who had not been exposed to pigeons in the same village were enrolled in the control group,inquired and recorded the relevant information of the research subjects in detail,improved the pulmonary function test,and detected the concentration and size of the surrounding aerosols.The effects of different concentrations and sizes of loft environmental aerosols on the pulmonary function of the pigeon breeders(FEV 1,FVC,FEV 1%,FVC%,FEV 1/FVC)were analyzed,and the correlation between lung function and the years of pigeons raised,the number of pigeons raised and the daily contact time was analyzed.Results The aerosol concentration in the loft environment of the contact group was higher than that of the control group.Compared with the control group,it was found that FVC,FEV 1%,FVC%and other pulmonary function indicators were all lower the contact group,and there were significant differences between the two groups(P<0.05);Aerosol concentration was negatively correlated with FEV 1,FVC,FEV 1%,FVC%,FEV 1/FVC and other pulmonary function indexes,and the correlation was statistically significant(P<0.05).The raised years were negatively correlated with FEV 1,and the correlation was statistically significant(P<0.05).But there were no significant correlation between raised number and FEV 1,FVC,FEV 1%,FVC%and FEV 1/FVC(P>0.05).Conclusion Raising pigeons can increase the aerosol concentration in the loft environment,and the higher the aerosol concentration,the longer the raising years,the longer the daily contact time with pigeons,the more obvious the decrease in lung function-related indexes.
