The objective of this study was to investigate the relationship between sand dust particles and pulmonary function, and respiratory symptoms in adult patients with asthma. One hundred thirty-seven patients were included in the study. From March 2013 to May 2013, the patients measured their morning peak expiratory flow (PEF) and kept daily lower respiratory symptom diaries. A linear mixed model was used to estimate the correlation of the median daily levels of sand dust particles, symptoms scores, and PEF. A heavy sand dust day was defined as an hourly concentration of sand dust particles of >0.1 km(-1). By this criterion, there were 8 heavy sand dust days during the stInternational journal of environmental research and public health13038-52https://www.ebi.ac.uk/biostudies/studies/S-EPMC4627015biostudies-literatureAssociation of Sand Dust Particles with Pulmonary Function and Respiratory Symptoms in Adult Patients with Asthma in Western Japan Using Light Detection and Ranging: A Panel Study.PMC4627015Ohga HShimizu EUeda YYamasaki AMikami MNoma HKurai JKato KIgishi TShimizu AKitano HWatanabe MSano HTatsukawa TfalseAssociation of Sand Dust Particles with Pulmonary Function and Respiratory Symptoms in Adult Patients with Asthma in Western Japan Using Light Detection and Ranging: A Panel Study.Light detection and ranging (LIDAR) can estimate daily volumes of sand dust particles from the East Asian desert to Japan.
