Ambient Air Pollution and Chronic Bronchitis in a Cohort of U.S. Women.

ABSTRACT:

Background

Limited evidence links air pollution exposure to chronic cough and sputum production. Few reports have investigated the association between long-term exposure to air pollution and classically defined chronic bronchitis.

Objectives

Our objective was to estimate the association between long-term exposure to particulate matter (diameter <10 μm, PM₁₀; <2.5μm, PM_2.5), nitrogen dioxide (NO₂), and both incident and prevalent chronic bronchitis.

Methods

We estimated annual average PM_2.5, PM₁₀, and NO₂ concentrations using a national land-use regression model with spatial smoothing at home addresses of participants in a prospective nationwide U.S. cohort study of sisters of women with breast cancer. I
