ABSTRACT BACKGROUND: A nonlinear association between coffee consumption and CVD risk was observed in meta-analysis. Moderate coffee consumption was inversely significantly associated with CVD risk, with the lowest CVD risk at 3 to 5 cups per day. Heavy coffee consumption was not associated with elevated CVD risk.There has been an increasing trend of caffeine beverage consumption in Thailand. However, little was known about the consumer behavior on caffeine beverage among the working age group in Thailand. This study aimed to describe caffeine beverage consumption behavior among working age group in Khon Kaen province, Thailand.
