Asian Dust and Pediatric Emergency Department Visits Due to Bronchial Asthma and Respiratory Diseases in Nagasaki, Japan
Background: The adverse health effects of Asian dust (AD) on the respiratory system of children are unclear. We hypothesized that AD events may lead to increased visits by children to emergency medical centers due to bronchial asthma and respiratory diseases, including bronchial asthma. Methods:...

| description | Background: The adverse health effects of Asian dust (AD) on the respiratory system of children are unclear. We
hypothesized that AD events may lead to increased visits by children to emergency medical centers due to bronchial
asthma and respiratory diseases, including bronchial asthma.
Methods: We used anonymized data on children receiving primary emergency treatment at Nagasaki Municipal
Primary Emergency Medical Center, Japan between March 2010 and September 2013. We used Light Detection and
Ranging (LIDAR) data to assess AD exposure and performed time-stratified case-crossover analyses to examine the
association between AD exposure and emergency department visits. The main analysis was done with data collected
from March through May each year.
Results: The total number of emergency department visits during the study period was 756 for bronchial asthma
and 5421 for respiratory diseases, and the number of “AD days” was 47. In school children, AD events at lag day 3
and lag day 4 were associated with increased emergency department visits due to bronchial asthma, with odds ratios
of 1.837 (95% confidence interval [CI], 1.212–2.786) and 1.829 (95% CI, 1.179–2.806), respectively. AD events
were significantly associated with respiratory diseases among preschool children at lag day 0, lag day 1, and lag day
2, with odds ratios of 1.244 (95% CI, 1.128–1.373), 1.314 (95% CI, 1.189–1.452), and 1.273 (95% CI, 1.152–1.408),
respectively. These associations were also significant when the results were adjusted for meteorological variables and
other air pollutants.
Conclusions: The study findings suggested that AD exposure increases emergency department visits by children. |
