Abstract
ZHOU and colleagues, Department of Biochemistry and Molecular Biology, New York Medical College, Valhalla NY 10595 USA investigated the relationship between diet and the risk of lung cancer among women in China.
Background
Methodology
The authors conducted a case-control study of lung cancer incidence among women in Shenyang, China to explore the relationship between diet and lung cancer risk, with emphasis upon the potential effects of specific dietary nutrients. In being able to modify lung cancer risk. Dietary information regarding 290 cases and population-matched controls was obtained using personal interviews.
Results
There was a significant difference between cases and controls with respect to intake of beta-carotene, vitamin C and fibres, all of which reduced the risk for lung cancer in a dose-dependent manner, with 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.
Conclusion
Beta-carotene, vitamin C and fibre may function as protective factors to reduce the risk of lung cancer in women in China.
