Living in lower income zip codes is associated with more severe chronic rhinosinusitis

Chronic rhinosinusitis (CRS) is a chronic inflammatory condition afflicting the upper airways. In 2014, approximately 29.4 million adults reported being told by a doctor or other health professional in the past 12 months that they had sinusitis.1 The pathogenesis of CRS is multifactorial, likely due to a combination of host and environmental factors.2 Determining whether the host factors are due to nonmodifiable, such as race, or modifiable risk variables is important. Previous analyses of the effect of socioeconomic status on CRS have yielded conflicting results.
