Background: The aim of this study was to investigate prevalence of tea, coffee and Nescafe consumption among high school students in Shiraz, Iran and find out whether there is a relationship between these three beverages with depression and anxiety.

Methods: A cross-sectional survey was conducted among high school students in Shiraz, Iran in 2014. A total of 1020 students, including 510 female (50%) and 510 male (50%), were interviewed according to Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) criteria. Data were collected using Demographic, anxiety and depression questionnaires. The obtained data were analyzed using SPSS version 16. We used descriptive methods, Chi square tests and Pearson correlation.

Results: Prevalence of tea, coffee and Nescafe consumption in high school students in Shiraz was 79.5%, 54% and 54% respectively. There was an inverse significant relationship between consumption of these three beverages with depression and anxiety (P < 0.05). Conclusion: We found out that prevalence of tea, coffee and Nescafe consumption among high school students was considerable and that of tea consumption was more than two other beverages. Also our findings support an inverse relationship between tea, coffee and Nescafe consumption with anxiety and depression.
