A 1:1 case-control study of lung cancer incidence among women in Shenyang was conducted to explore the relationship between diet and the risk of lung cancer, with emphasis on the potential effects of a list of specific dietary constituents on modifying lung cancer risks. Dietary information on 290 cases and population-matched controls was obtained by personal interviews. Multiple logistic regression models were used for the statistical analysis and summarization of the data. A significant difference was found between cases and controls with respect to intake of beta-carotene, vitamin C and fibers, all of which reduced the risk for lung cancer in a dose-dependent manner; yielding calculated odds ratio (OR) of 0.84, 0.75, and 0.46, respectively. The apparent effects of these nutrients persisted after adjusting for cigarette smoking;suggesting that they may function as protective factors to reduce the risk for lung cancer in Chinese women.
