title: A Cross-sectional Study of the Relationship Between Habitual Tea Consumption and Arterial Stiffness.
abstract: To explore the relationship between habitual tea consumption and arterial stiffness.
  
  
  
  This is a cross-sectional, epidemiological survey of 6589 male and female residents aged 40-75 in Wuyishan, Fujian Province, China. Tea consumption and other lifestyle characteristics were obtained by structured questionnaires. Pulse wave velocity (PWV) and ankle-brachial pressure index (ABI) were measured using an automated analyzer.
  
  
  
  Among the 5006 analyzed subjects, 1564 adults (31.2%) consumed tea once or more per week for at least one year. The levels of brachial-ankle pulse wave velocity (ba-PWV) were lowest among subjects who consumed tea habitually for more than 10 years compared with the other 3 subgroups (nonhabitual, 1 to 5 years, and 6 to 10 years habitual tea drinkers), and the levels of ba-PWV were lower with subjects who consumed 10-20 and >20 g/d tea habitually compared to nonhabitual tea drinkers. As the duration and the daily amount of habitual tea consumption increased the average ba-PWV decreased. Multiple logistic regression models revealed that habitual tea consumption was a positive predictor for ba-PWV (odds ratio [OR] = 0.63, 95% confidence interval [CI], 0.57-0.70).
  
  
  
  Habitual tea consumption may have a protective effect against arterial stiffness, especially for subjects who have habitually consumed tea for more than 6 years and >10 g daily.
