For each 10-\u00b5g\/m\u00b3 increase in PM<sub>10<\/sub>, the adjusted odds ratios for mild, moderate, and high rhinitis severity were 1.20 (95 percent confidence interval [CI], 0.88 to 1.64), 1.53 (95 percent CI, 1.07 to 2.19), and 1.72 (95 percent CI, 1.23 to 2.41), respectively. For higher levels of exposure to PM<sub>2.5<\/sub>, the results were similar. The researchers reported that exposure to NO<sub>2<\/sub> was also associated with increased symptom severity, but an exposure-response relationship was not found.<\/p>\n<p>&#8220;This study contributes to our understanding of rhinitis, a disease which, although not fatal, represents a major public health challenge and is associated with a negative impact on the quality of the daily lives of those affected and a very high burden on public funds owing to the treatments prescribed, decreased productivity, and absenteeism,&#8221; a coauthor said in a statement.<\/p>\n<p>One author disclosed financial ties to pharmaceutical companies.<\/p>\n<p><a href=\"https:\/\/www.jacionline.org\/article\/S0091-6749(19)31636-7\/fulltext\" target=\"_new\" rel=\"noopener noreferrer\">Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n<p><i><\/i><\/p>\n<p><i>Copyright \u00a9 2020 <a href=\"https:\/\/www.healthday.com\/\" target=\"_new\" rel=\"noopener noreferrer\">HealthDay<\/a>.
