Betel nut chewing is related to several kinds of cancer, metabolic syndrome, and type 2 diabetes. Whether it is associated with a greater risk of cardiovascular disease (CVD) and all-cause mortality, however, remains unclear. ⋯ Betel nut chewing was independently associated with a greater risk of CVD and all-cause mortality in Taiwanese men. Regular screening for betel nut chewing history may help prevent excess deaths in the future. An anti-betel nut chewing program is urgently warranted for current chewers.
