Abstract:
Objective:To investigate the association between tea consumption and lung cancer risk in Chinese males.
Methods:Tea consumption and incident lung cancer cases were collected on a biennial basis among males in Kailuan Cohort during 2006-2015. Up to 31st December 2015, a total of 103 010 male candidates from the Chinese Kailuan Male Cohort Study were enrolled in the present study. Cox proportional hazards regression model was used to evaluate the association between tea consumption and risk of lung cancer in males.
Results:The age of male candidates was (51.3±13.4)years old. There were 828 810.74 person-years of follow-up and 8.91 years of median follow-up period. During the follow-up, 964 lung cancer cases were identified. In male, the rate of never cosumers, tea drinkers (<4/week) and tea drinkers (≥4/week) were 58.17%(n=59 926), 24.04%(n=24 765) and 17.78%(n=18 319), respectively. After adjustment for potential confounding factors, HR (95%CI) of lung cancer for subjects with tea drinkers (<4/week) and tea drinkers (≥4/week) were 0.80 (0.63-1.02) and 1.02 (0.80-1.30), respectively, as compared with never cosumers. The results showed no significant association with lung cancer. Stratification analysis and sensitivity analysis showed no significant changes.
Conclusion:Our study has not found that tea consumption is significantly associated with the risk of male lung cancer.
