Long-term exposure to air pollution and mortality in the Danish population a nationwide study.

ABSTRACT:

Background

Studies have shown higher mortality in association with exposure to air pollution. We investigated this association with focus on differences between socioeconomic groups.

Methods

We included all Danes born between 1921 and 1985 aged 30-85 years from 1991 to 2015 (N = 4,401,348). We applied a nested case-control design and identified those who died during follow-up and selected five controls per case. We modelled NO₂, fine particulate matter (PM_2·5), black carbon (BC) particles, and ozone (O₃) as five-year average concentrations at the residential addresses of 672,895 all natural cause mortality cases and 3,426,533 controls in conditional logistic regression with adjustment for individual and neighbourhood level socio-demogr
