Lung Cancer Risk and Residential Exposure to Air Pollution: A Korean Population-Based Case-Control Study.

ABSTRACT:

Purpose

To investigate the association between long-term exposure to ambient air pollution and lung cancer incidence in Koreans.

Materials and methods

This was a population-based case-control study covering 908 lung cancer patients and 908 controls selected from a random sample of people within each Korean province and matched according to age, sex, and smoking status. We developed land-use regression models to estimate annual residential exposure to particulate matter (PM₁₀) and nitrogen dioxide (NO₂) over a 20-year exposure period. Logistic regression was used to estimate odds ratios (ORs) and their corresponding 95% confidence intervals (CI).

Results

Increases in lung cancer incidence (expressed as adjusted OR) were 1.09 (95% CI: 0.96-1.23) with a ten-unit increase
