Abstract:
Objective To understand the relationship between green tea drinking and/or garlic consumption and lung cancer.Methods A population-based case-control study was conducted in Ganyu county,Jiangsu province.Epidemiological data including demography,lifestyle,environmental exposures and dietary habits were collected by face-to-face interviews using a standardized questionnaire.Unconditional logistic regression was used to estimate adjusted odds ratios (OR) and their 95％ confidence intervals (CI) in both univariate and multivariate analyses.Results Both green tea drinking and garlic consumption were inversely associated with lung cancer and the adjusted ORs were:0.78 (95％CI:0.65-0.95) for green tea,0.79 (95％ CI:0.66-0.95) for garlic intake,and 0.69 (95％CI:0.53-0.89) for both,respectively.They also modified the associations of smoking,fried food intake and cooking oil under high-temperature with lung cancer as risk factors.Potential interactions were found between garlic or green tea and the risk factors of lung cancer.Conclusion Both green tea drinking and garlic consumption might serve as protective factors on lung cancer.
