ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of dust exposure and smoking on mortality.</p><p><b>METHODS</b>Based on the Guangzhou Occupational Health Surveillance Record System established in 1989-1992, 61,648 factory workers, aged > or = 30, occupationally exposed to dust and non-exposure to dust or any other hazardous substances(controls), were included in a prospective cohort study.</p><p><b>RESULTS</b>(1) 28 were lost to follow-up. Malignant neoplasm was most common among 1,186 deaths. (2) Most subjects were male workers, aged 35 to 44, with secondary education, and married. 42.2% had ever smoked and 32.8% were ever-drinkers. (3) To compare with non-exposure, non-smoking + non-smoking and non-exposure respectively, the adjusted RR of death from all causes, malignant neoplasm and respiratory diseases were 1.24, 1.34 and 1.96 respectively for dust exposed workers(compared to control, P < 0.01), 1.16, 1.37 and 1.63 respectively for those smoking(compared to non-smoker except RR of death from respiratory diseases, P < 0.01), and 1.48, 1.85 and 3.12 respectively for those smoking and dust exposure, which were far greater than those either smoked or exposed to dust alone(P < 0.01). (4) The influence of dust exposure on death was mainly showed in occupational exposure to silica dust and wood dust.</p><p><b>CONCLUSION</b>Both dust exposure and smoking may increase the mortality, and they had synergistic effect.</p>
