Chinese tea consumption and lower risk of XXXX .

@entity1 @entity13639
BACKGROUND: Our first study had shown that Chinese tea has anti-Helicobacter activity. The present study investigated the relationship between @entity1 'Helicobacter status and the history of Chinese tea consumption. METHODS: Chinese @entity1 who had their first upper endoscopy were recruited. Before the procedure, @entity1 completed questionnaires about their current Chinese tea consumption habits and those when they were around 10-25 years old. This information was used to calculate the tea consumption indices (TCI). Gastric biopsies (two from the antrum and two from the corpus) were taken for histological examination for Helicobacter. RESULTS: Eighty @entity1 were recruited. Eight @entity1 were rejected because of either an incomplete questionnaire, absence of gastric biopsy or a suspected history of treatment for @entity13639 . Of the 72 @entity1 , 42 (58.3%) were Helicobacter positive. The age, sex ratio and indications for endoscopy were similar in both Helicobacter-positive and -negative groups. Classifying @entity1 using either current, past or total TCI, @entity1 with high tea consumption had significantly lower @entity13639 rate than those with low tea consumption (45% compared to 74%, 42% compared to 67% and 40% compared to 83%, respectively). Helicobacter-negative @entity1 had higher overall TCI than Helicobacter-positive @entity1 (28.2:17.3). When current and previous histories were analyzed separately, Helicobacter-negative @entity1 also had a trend towards higher TCI currently (16.6:11.0) and in their 20s (11.6:6.1). CONCLUSIONS: There is a significant inverse relationship between Chinese tea consumption and @entity13639 . Chinese tea consumption may decrease the chance of @entity13639 .
