The first cohort study
in Europe has been published recently (Hoek et al, 2002). This has consisted in a Dutch
cohort of 5000 adults followed during 7 years. Findings indicate an association between
cardiopulmonary mortality and living near a major road (relative risk 1·95, 95% CI
1·09-3·52) and, less consistently, with the estimated ambient background concentration
of black smoke (1·34, 0·68-2·64). Non-cardiopulmonary, non-lung cancer deaths were
unrelated to air pollution (1·03, 0·54-1·96 for living near a major road). No clear
association was found with other estimates of long term exposures. Too few people died
from respiratory disorders and lung cancer to obtain stable estimates for the indicator
variable for living near a major road. |
