Prevalence and associated factors of symptomatic dry eye among undergraduate students in Hawassa University College of Medicine and Health Sciences, Hawassa, Ethiopia

OBJECTIVE: This study aimed to assess the prevalence and associated factors of symptomatic dry eye (SDE) among undergraduate students at the College of Medicine and Health Science, Hawassa University, Ethiopia. METHODS AND ANALYSIS: Institution-based cross-sectional study was conducted using a systematic random sampling technique. A total of 311 undergraduate students were recruited to execute the study. Ethical clearance was obtained from the ethical review committee of the school of Medicine and Health Science. A standardised self-administered questionnaire was used to collect the data. Data were entered using Epi Info V.7 and cleaned and analysed using SPSS V.23. Binary and multivariable logistic regression analysis was done to select candidate variables and to identify statistically significant factors. Variables with a p value of <0.05 on multivariable analysis were reported as statistically significant. RESULTS AND CONCLUSION: The overall prevalence of SDE was found to be 49.4% (95% CI 43.7% to 55.1%). In this study, the history of ophthalmic drop use (adjusted OR, AOR 2.063; 95% CI 1.073 to 3.957) and being second (AOR 5.99; 95% CI 1.10 to 32.56) and third (AOR 11.55; 95% CI 2.12 to 62.94) year student were factors that significantly associated with SDE. In this study, the prevalence of SDE was significantly high. The factors associated with SDE were the use of ophthalmic drops and the class year of students. Therefore, public health education about protective measures should be considered to minimise the effects of SDE on the quality of life of students.
