Finding F-1797

“There was a log-linear positive association between exposure to household air pollution and lung cancer death, with a 4% increased risk per 5-year increment of exposure (hazard ratio = 1.04; 95% confidence interval= 1.01–1.06; P trend = 0.0034)”

Structure

Source: Solid fuel
Outcome: Lung cancer
Setting: home
Study design: prospective cohort: lifetime exposure to household air pollution from solid fuel reconstructed by interview and lung cancer death ascertained over the follow-up, with risk modelled against cumulative duration of exposure (class 3)
Effect: HR 1.04 (1.01–1.06) per 5
Caveat: ever exposure on its own was not significantly associated with lung cancer death; it is the duration that carries the association
