To analysis the risk factors of lung cancer and determine the surveillance index in urban areas in four metropolises in China. The paper used the data from the in-person interviews of National Research on Malignant Tumor Morbidity, Mortality and Surveillance Methods in 1996. We carried out a 1:1 matched case-control study based on population involving 1 312 cases and 1 312 neighborhood controls aged 35 - 74 from Beijing, Tianjin, Shanghai, Chongqing urban areas. The relationships between risk factors and lung cancer were analyzed by conditional univariant and multivariate logistic regression on the computer package, STATA. Cigarette smoking, lower body mass index, longtime depressed mood, lower capability of emotion regulation, previous respiratory diseases, family history of cancer in first-degree relatives significantly increased the risk of lung cancer after adjusted by age, education, family average income and other risk factors. The odds ratios of these risk factors were 3.46 (95% CI 2.70 - 4.45), 1.18 (
