Long-term exposure to intermediate particulate matter is associated with incident asthma in adults aged 45 years and older, according to a recent study.Shuting Li of the Capital Medical University in Beijing, China, and the Beijing Municipal Key Laboratory of Clinical Epidemiology, and colleagues conducted the study due to &ldquo;insufficient evidence about the long-term effects of intermediate particulate matter on asthma development in adults aged 45 years and above.&rdquo;The researchers conducted the cohort study using the China Health and Retirement Longitudinal Study database to evaluate the long-term effects of intermediate particulate matter on the incidence of self-reported asthma in 6400 adults aged 45 years and older in China from 2011 to 2018. They estimated the particulate matter concentrations using a high-resolution, satellite-based spatiotemporal model.After 7 years of follow-up, 1.61% of the participants developed asthma, with each 10 &mu;g/m3 increment in the 1-year moving average concentration of intermediate particulate matter corresponding to a 1.82-fold increased risk for incident asthma.Each 10 &mu;g/m3 increment in the 2-year moving average concentration corresponded to a 1.95-fold higher risk for incident asthma, while each 10 &mu;g/m3 increment in the 3-year and 4-year moving averages corresponded to 1.95-fold and 1.88-fold increased risks of incident asthma, respectively.&ldquo;A significant multiplicative interaction was observed between socioeconomic level and long-term exposure to [intermediate particulate matter],&rdquo; the researchers wrote. &ldquo;Stratified analysis showed that smokers and those with lower socioeconomic levels were at higher risk of incident asthma related to [intermediate particulate matter].&rdquo;They also found an increasing trend in asthma incidence with increasing intermediate particulate matter.&ldquo;Long-term exposure to [intermediate particulate matter] was positively associated with incident asthma in middle-aged and elderly individuals,&rdquo; the study&rsquo;s authors concluded. &ldquo;Participants with a history of smoking and lower socioeconomic levels had a higher risk. More studies are warranted warrant to establish an accurate reference value of [intermediate particulate matter] to mitigate the growing asthma burden.&rdquo;Li S, Wei J, Hu Y, et al.
