The data were analyzed using SPSS 21, for data on continuous scale mean, median, standard deviation, standard error and confidence intervals, for comparisons independent t-test, ANOVA for group’s analysis and for correlations spearman’s rank correlation. Results Decreased sleep quality was noticed in 41.5% of the medical students. On the Beck anxiety severity scores, 29% had mild anxiety symptoms, 17% had moderate, and 8% had severe anxiety symptoms. Sleep quality and anxiety scores had a significant positive correlation r = 0.000. Screen use on an average weekday and background screen use on regular week days were positively correlated r = 0.007. Mild, moderate, and severe anxiety level groups had higher PSQI scores though not statistically significant. Correlation is significant at 0.01 level and P value significant at or <0.05.
