Short-Term Increases in Ambient Fine Particulate Matter Are Associated With Psoriasis Risk
Short-term exposure to elevated levels of ambient fine particulate matter (PM2.5) may be associated with the risk of psoriasis, according to a study published in Frontiers in Public Health.
In a time series analysis, researchers aimed to study the relationship between short-term exposure to PM2.5 and outpatient visits for psoriasis in Beijing, China. A generalized additive quasi-Poisson model was used to examine the relationship between daily PM2.5 concentrations and 500266 recorded outpatient visits for psoriasis.
Daily outpatient visits for psoriasis increased 0.29%, with a same day increase of 10 μg/m3 in PM2.5. Thus, short-term exposure to PM2.5 is correlated with outpatient visits for psoriasis-related health concerns. In addition, the association between PM2.5 concentrations and psoriasis-associated outpatient visits was greater in women (0.35%, 95% CI: 0.30–0.39%) and in older patients (0.41%, 95% CI: 0.34–0.48%).
“The present study provides robust evidence that short-term elevations in PM2.5 levels are related to the risk of psoriasis,” concluded the study authors. “Long-term observations, estimates of personal exposure, and consideration of other pollutants and lifestyle factors are required,” they added.
