Short-term exposure to air pollution may trigger some cases of appendicitis, Canadian researchers said.
In a study of nearly 5,200 adults admitted to hospital for acute appendicitis, high levels of ambient air pollutants such as ozone and
nitrogen dioxide were associated with an increased risk of the condition, Gilaad Kaplan, MD, of the
University of Calgary and colleagues reported.
Ozone, (OR 1.32, 95% CI 1.10 to 1.57)
Sulfur dioxide, (OR 1.30, 95% CI 1.03 to 1.63)
Nitrogen dioxide, (OR 1.76, 95% CI 1.20 to 2.58)
Carbon monoxide, (OR 1.35, 95% CI 1.01 to 1.80)
Particulate matter less than 10 microns in diameter, (OR 1.20, 95% CI 1.05 to 1.38)
