ABSTRACT
<p><b>OBJECTIVE</b>To assess the effect of tea consumption on the risk of endometrial cancer.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
