The association of residential distance from highly trafficked roads with atopic dermatitis risk.

The effect of traffic-related air pollution (TRAP) on respiratory health and all-cause mortality has been well described,1 and associations between proximity to major roads, reflecting increased pollutant exposure, and risk of asthma have been reported.2 Recently, the effect of TRAP on skin health and risk of atopic dermatitis (AD) has also been described in a study from Seoul, South Korea.3 Here we report findings from a large clinical population in Colorado, USA, evaluating the effect of road proximity on AD risk.
