Little research has investigated differences based on tea and coffee consuming
habits. Differences between drink-consumers associated with demographic or lifestyle
factors could have implications for research into caffeine effects on health or disease
states. This paper re-analyses data collected from a population-based survey (Smith
et al., 2000; Wadsworth et al., 2004a, b) of almost 8,000 respondents to address this
issues. The survey collected information about both caffeinated and de-caffeinated tea
and coffee consumption, as well as demographic, health and lifestyle factors. The aim
was to examine the relationship between tea and coffee consumption habits and the
demographic, health and lifestyle factors measured.
