Habitual tea consumption is associated with a reduced risk for atherosclerotic cardiovascular disease (CVD) and all-cause mortality, according to a study published online January in the European Journal of Preventive Cardiology.

Xinyan Wang, from the Chinese Academy of Medical Sciences and Peking Union Medical College, and colleagues examined the association of tea consumption with the risk for atherosclerotic CVD and all-cause mortality among 100,902 general Chinese adults in 15 provinces in China. Standardized questionnaires were used to obtain information on tea consumption.

The researchers found that 3,683 atherosclerotic CVD events, 1,477 atherosclerotic CVD deaths, and 5,479 all-cause deaths were recorded during a median follow-up of 7.3 years. For habitual tea drinkers, the hazard ratios were 0.80, 0.78, and 0.85 for atherosclerotic CVD incidence, atherosclerotic CVD mortality, and all-cause mortality, respectively, compared with never or nonhabitual tea drinkers. At the index age of 50 years, habitual tea drinkers were free from atherosclerotic CVD for 1.41 more years and had a life expectancy of 1.26 years longer. Among participants who kept the habit during follow-up, the observed inverse associations were strengthened.

"Our findings give a further insight into the beneficial role of tea consumption, and have great public health implications for guiding primary prevention among general Chinese adults," the authors write.
