Online published: 2011-06-27
Objective To explore the correlation between tea consumption and risk of ovarian cancer through Meta-analysis. Methods Relative studies published between 1995 and 2010 about tea consumption and risk of ovarian cancer were searched in Pubmed, EMbase, CBMdisc, CNKI and Wanfang Data. All reports were systemically reviewed, and Meta-analysis was performed by RevMan 5.1.0 software. Results A total of 9 domestic and overseas case-control studies and cohort studies were included, with 4 571 cases and 65 215 controls. Meta-analysis revealed that tea consumption significantly decreased the risk of ovarian cancer (RR, 0.82; 95%CI, 0.70-0.96; P<0.001), and the effect was more significant for green tea consumption (RR, 0.69; 95%CI, 0.54-0.90; P=0.006). Conclusion Tea consumption, especially green tea consumption, may reduce the risk of ovarian cancer.
