[Risk factors of lung cancer--follow-up studies in Nagoya Japan].
A population-based follow-up study on the relationships between various environmental factors and risks of lung cancer has been conducted in Nagoya, Japan involving 24,489 inhabitants aged 40 or older. The baseline survey was conducted in 1985, using a self-recorded questionnaire. From a 10 year follow-up study, 161 cases with a newly diagnosed lung cancer (120 male cases and 41 female cases) were identified. Various environmental factors were related to the subsequent risk of lung cancer incidence. Causal relationship between smoking and lung cancer was noticed for current male smokers (RR = 5.72; 95% CI = 2.50-13.08) and for current female smokers (RR = 2.05%; 95% CI = 0.97-4.32). However, relative risks for other environmental factors were not statistically significant except increased risk for frequent coffee drinking in males (aRR = 2.02; 95% CI = 1.34-3.05) and decreased risk for frequent intake of green/yellow vegetables in females (aRR = 0.47; 95% CI = 0.23-0.94).
