Is the use of portable stoves associated with lower lung cancer mortality risk among lifetime smoky coal users?

Using portable stoves is linked to a reduced risk of lung cancer mortality in both men and women who have used smoky coal.

Portable stove users had a significantly lower probability of dying from lung cancer compared to those who did not change stoves.
Men and women who switched to portable stoves had hazard ratios of 0.62 and 0.41 for lung cancer mortality, respectively.
Fewer subjects with portable stoves reported chronic bronchitis compared to those without stove change.

Switching from traditional stoves to portable stoves can help people live longer by reducing the chances of getting lung cancer.

The study used a retrospective cohort design, analyzing lung cancer mortality among farmers who changed from unvented stoves to portable stoves.

Recall bias may have affected the accuracy of reported fuel usage.

The study may have biases due to differences in participant characteristics and potential recall bias.

Participants were farmers born between 1917 and 1951, primarily from Xuanwei, China.
