BURDEN OF TUBERCULOSIS AMONG STUDENTS IN TWO ETHIOPIAN UNIVERSITIES.

Abstract

Introduction: Tuberculosis outbreaks emerge occasionally in long-term care facilities and various educational establishments. This study was designed to determine the five year overall prevalence and trend of tuberculosis and associated factors among students at Adama Science and Technology University and Addis Ababa University Sidist Kilo campus.

Methods: A five-year retrospective study was conducted on students’ medical records of tuberculosis Directly Observed Treatment Short Course clinics from September 2009– July 2014. The overall prevalence and the trend of smear positive, smear negative and extra pulmonary tuberculosis cases was determined. Odds ratio with 95 percent confidence interval was calculated for categorical variables using a multivariate logistic regression model to assess the strength of association.

Results: A total of 112 and 263 tuberculos cases were recorded in Addis Ababa University Sidist Kilo campus and Adama Science and Technology University, respectively. The mean proportion of tuberculosis cases of all types among the total number of students enrolled at Adama Science and Technology University and Addis Ababa University Sidist Kilo campus was 1098.1 and 511.7 cases per 100,000 population, respectively. There was a statistically significant difference in prevalence of tuberculosis among students in Adama Science and Technology University compared to that in Addis Ababa University Sidist Kilo campus [adjusted odds ration: 2.881, 95% CI (1.76-4.71)]. The trend of tuberculosis prevalence showed a steady decline from the first to the last year of the study period.

Conclusion: The number of tuberculosis cases observed among university students in this study was high. Governmental and nongovernmental agencies involved in tuberculosis control must consider higher education institutions as focal points for prevention and elimination of tuberculosis in Ethiopia.
