Background: In Ethiopia, intestinal parasitic diseases are one of the major causes of morbidityrnnationwide. In addition to that, intestinal parasites have significant socioeconomic problem inrnterms of productivity, school performance and cost for diagnosis and treatment. Intestinalrnparasitosis is one of the major problems among student of Addis Ababa University who visitedrnstudent clinics.rnObjective: The purpose of this study is to assess the magnitude and determinants of intestinalrnparasitosis among Addis Ababa University students who utilize AAU student clinic service,rnAddis Ababa, Ethiopia.rnMethods: Health facility based cross-sectional study design was employed. Total of 556rnstudents were selected by systematical cluster sampling from the three campuses (Main, Northrntechnology, Science). Self- administered, close and open ended coded questionnaire wasrnprepared to assess their knowledge attitude and practice towards intestinal parasite, personalrnhygiene and sanitation. Finally the stool samples was diagnosed using direct wet mount andrnconcentrated technique then the data was analyzed using Crude and adjusted Odds ratio withrn95% confidence interval at P < 0.05 to check whether there were significant association betweenrndependent and independent variables.rnResult: A total of 556 study subjects were participated, of which 424(76.3 %) were males. Outrnof total, 134 of them had at least one parasitic infestation with an overall prevalence of 24.1%, ofrnwhich 108(80.6%) were males. Out of total study subjects, 326(58.6%) had abdominal pain orrndiscomfort during two weeks before the survey. Cafeteria usage and eating street food werernsignificantly associated with intestinal parasitosis [AOR: 2.1, 95% CI (1.2, 5.0)] and [AOR: 2.6,rn95% CI (1.45, 3.51)], respectively. Technology campus fulfilled nearly 2/3 of sanitaryrnrequirements while, Main and Science campus fulfilled less than half of the requirement.rnConclusion and recommendation: There was high prevalence of intestinal parasitosis andrnpresence of abdominal pain or discomfort among the university students. The amount of waterrnand toilet availability in cafeteria and student dormitory did not met the required sanitaryrnstandards. Sanitary building codes and enforcement needs to be in place for the current andrnnewly built dormitories and cafeteria services.
