This requires research which examines insomnia and anxiety assessing the contribution of the factors influencing anxiety.Methods: A cross-sectional study methodology with linear regression analysis on a sample of students from the Faculty of Medicine, University of Pelita Harapan using the DASS-21 questionnaire to assess anxiety and ISI to assess insomnia.Results: Prevalence rates of insomnia was 34.29% and anxiety 32.38% in Pelita Harapan University medical student. From the results of the bivariate linear regression, a weak relationship between insomnia and anxiety (r = 0.322; p = 0.000) is seen. In multivariate results, there were confounding stress variables (r = 0.565; p= 0.000) and trauma (r = 0.250; p = 0.005) which contributed greatly to anxiety (In order of largest).Conclusion: There is a weak correlation and anxiety.
