Results
Approximately 30% of the cohort members reported drinking green tea regularly at baseline. Among green tea drinkers, the median monthly consumption was 100 g dry weight of tea leaves, ranging from 50 g (the 25th percentile) to 150 g (the 75th percentile). The median duration of lifetime green tea consumption was 16 years, ranging from 8 years (the 25th percentile) to 24 years (the 75th percentile). Compared with those who never or occasionally drank tea, regular tea drinkers were slightly younger, had higher household income and educational attainment, and tended to exercise regularly and consume a little more vegetables and fruits (Table 1 ). There were no appreciable or only slight differences in body mass index, waist-to-hip ratio, intakes of total energy and red meat, and family history of CRC between tea drinkers and nondrinkers. Few women in this cohort ever smoked cigarettes (2.7%), drank alcoholic beverages (2.3%), or used aspirin and other nonsteroidal anti-inflammatory drugs (1.8%) or postmenopausal hormones regularly (2.2%).
