Claim C-0003

In adults, long-term exposure to nitrogen dioxide (NO₂) is associated with newly diagnosed atopic dermatitis.

Structure

Factor: Nitrogen dioxide (NO₂)
Outcome: Atopic dermatitis (eczema)
Population: adults
Relation: increases · odds ratio 1.30 (95 % CI 1.04–1.61) per 10 µg/m³
Evidence grade: B · single-study
Caveat: the exposure measured is outdoor air and the estimate rests on a single systematic review; the grade table would allow A, but one review of one exposure route is kept at B

Based on

Finding F-0002: “Exposures to particulate matter < 2.5 μm in diameter (PM2.5) and NO2 were associated with incident AD, with ORs of 2.30 (95% CI: 1.25, 4.25) and 1.30 (95% CI: 1.04, 1.61) per 10 μg/m3 increase respectively.” (CKB 0637, p. 4)
