M Many studies describe the level of anxiety in medical students. Consuming caffeinated beverages is also the choice of medical students in increasing learning productivity. A number of studies have shown that there is a significant relationship between caffeine and anxiety, whereas several other studies have shown no significant relationship between the two. This shows that research is still needed to determine whether there is a significant relationship between caffeine consumption and anxiety. This study is a cross-sectional study which included 310 students of the Faculty of Medicine of Trisakti University in Jakarta according to the research exclusion criteria. Data were obtained by filling out questionnaires consisting of sociodemographic questionnaires, caffeine questionnaires, and the modified Ayang HAM-questionnaire. Data analysis was carried out using the SPSS for Windows version 20.0 program with a significance level:  = 0.05. The analysis was started by testing the validity and reliability of the modified HAM-A questionnaire, then continued with univariate and bivariate analysis. RESULTS Chi-Square analysis showed a relationship between the frequency of consumption of chocolate drinks to anxiety (df = 1;  2 = 5.172; p = 0.023) with a less significant correlation (C = 0.137; C ≤ 0.354). While the frequency of consumption of caffeinated drinks, the frequency of coffee consumption, and the frequency of the consumption were not related to anxiety (df = 1; 2≤ 3.841; p 5 0.05). There is a relationship between the frequency of consumption of chocolate drinks with anxiety, but less meaningful. In general, this study shows that there is no meaningful relationship between consumption of caffeinated beverages and anxiety in Trisakti University Medical School students.
