[Green tea consumption and the risk of endometrial cancer: a population-based case-control study in urban Shanghai].
Zhonghua Liu Xing Bing Xue Za Zhi. 2005 May; 26(5):323-7.ZL

Abstract

OBJECTIVE

To assess the effect of tea consumption on the risk of endometrial cancer.

METHODS

In a population based case-control study conducted in urban Shanghai, face-to-face interviews were completed for 995 incidence cases aged 30 - 69 from January 1997 to December 2002 and 1087 controls that frequency-matched to cases on age. Unconditional logistic model was used for analysis.

RESULTS

An inverse association was observed in tea drinking and endometrial cancer risk. Compared to non-tea drinkers, regular tea drinkers had reduced risk of endometrial cancer (OR = 0.74; 95% CI: 0.54 - 1.01) in premenopausal women. Green tea had a protective effect on endometrial cancer among non-smoking or non-alcohol drinking women (OR = 0.77, P = 0.0199) and the ORs reduced with the increasing concentration of tea being served (P for trend = 0.0493). The multivariate ORs for drinking green tea < 7 times/week and >or= 7 times/week were 0.90 (95% CI: 0.53 - 1.54) and 0.76 (95% CI: 0.60 - 0.95) with the trend test of P = 0.0163.

CONCLUSION

Tea drinking, with green tea in particurlar, seemed to have weak but inverse association with endometrial cancer risk, but this effect of protection might only limit to premenopausal women.
