Objective: To examine the association between tea drinking and the risk of lung cancer in Chinese population.
Methods: All relevant published articles in Chinese and English literature database were identified. Meta-analysis was conducted. Combined odds ratio (OR) and 95% confidence interval (CI) were calculated to estimate the associations and dose-response relationship between tea drinking and the risk of lung cancer.
Results: Twelve studies were included. An inverse association with lung cancer was observed on tea drinkers when compared to non-tea drinkers (OR = 0.66, 95%CI: 0.49 - 0.89).
Conclusion: Tea drinking might serve as a protective factor on lung cancer in the Chinese population.
