Background: Utilization of Internet is critical to retrieve health information particularly for countries where health care delivery system is incongruent with its population otherwise it could be difficult to address all health problems of the people with limited health professionals. This study sought to determine the magnitude of the Internet use for health information and its associated factors.Objective: The aim of this study was to assess the status of Internet utilization to access health information and its associated factors among the undergraduate students in Addis Ababa University, Ethiopia.Methods: A facility based cross-sectional study was conducted among 845 undergraduate students who were selected by Stratified multi-stage sampling from 19 randomly selected departments of Addis Ababa University. Data were collected from March to April 2019 using a pretested structured interviewer-administered questionnaire. The data were entered in to Epi-Info version 7 and exported to the SPSS version 23 for analysis. A binary logistic regression analysis was conducted to assess the association between the study and outcome variables. Result: Almost all 761 (98.8%) of the University students have ever used the Internet for general purposes. Among these the proportion of Internet use, about 59.1% (95% CI: 55.5-62.7) of them used the Internet for health information. Adjusting for all other factors in the final model, Digital health literacy (AOR=1.656, 95% CI: (1.143, 2.397), field of study (AOR= 0.025, 95% CI: (0.007, 0.087), year of study (AOR= 1.609, 95% CI: (1.130, 2.290), and computer device ownership (AOR= 2.314, 95% CI: (1.392, 3.844) were found to be significantly associated with the Internet use for health information.Conclusion: The proportion of Internet use for health information was found to be lower. Digital health literacy, being health science student, year of study and computer ownership were found to be important predictors.
