Risk of lung cancer associated with domestic use of coal in Xuanwei, China: retrospective cohort study.

ABSTRACT:

Objective

To estimate the risk of lung cancer associated with the use of different types of coal for household cooking and heating.

Setting

Xuanwei County, Yunnan Province, China.

Design

Retrospective cohort study (follow-up 1976-96) comparing mortality from lung cancer between lifelong users of "smoky coal" (bituminous) and "smokeless coal" (anthracite).

Participants

27,310 individuals using smoky coal and 9962 individuals using smokeless coal during their entire life.

Main outcome measures
