Air pollution could contribute to the risk of eczema

Exposure to air pollution could increase the risk of eczema.

In a study published in PLOS ONE, investigators examined data involving 286,766 participants from the All of Us Research Program. They linked electronic health records from the participants to air pollution data from the Center for Air, Climate and Energy Solutions across 788 distinct three-digit zip codes.

The investigators discovered that the participants who resided in areas with higher concentrations of fine particulate matter had about twice the risk of developing eczema. They hypothesized that polycyclic aromatic hydrocarbons — a component of fine particulate matter — may penetrate the stratum corneum and active pathways leading to barrier dysfunction and inflammation.
