The habit of drinking tea is highly prevalent in Asian countries. The aim of this study was to investigate the prevalence of tea drinking and to explore the correlated factors on tea drinking among young new students in the university, using a validated self-reported questionnaire. This study was carried out with 5936 new students in a university in Taiwan. It comprised a self-administered structured questionnaire, including items related to personal and medical history, and lifestyle habits, using the Pittsburgh Sleep Quality Index (PSQI) and the 12-item Chinese Health Questionnaire (CHQ-12). Anthropometric measurements and laboratory tests were also performed. In total, 2065 (36.1%) students were in the tea-drinking group. Multiple logistic regression analysis showed the following factors were significant predictors of tea drinking: postgraduate students (p < 0.001), coffee drinking (p < 0.001), alcohol drinking (p < 0.001), minor mental morbidity (p = 0.009), poorer sleepers (p = 0.037), higher body mass index (p = 0.004), and sugar-sweetened beverage consumption (p < 0.001). Our data showed that the tea-drinking habit was correlated with higher body mass index, which was contrary to the findings of a previous study. In clinical practice, perhaps we could consider more tea-drinking-related factors when we suggest tea consumption.
