Background: Parasitic infections, especially intestinal agents could affect social and personal hygiene and health; and to avoid the spread of pollution, monitoring the infectious sources is critical. Objective: The aim of this study is to estimate the prevalence of intestinal parasites and identify factors associated with intestinal parasitic infections among students of Jahrom University of Medical Sciences between 2013-1014. Materials and Methods: This study was carried out between September 2013and February 2014. A total number of 1293 stool samples were taken from 431 students and were examined by direct wet mounting and formalin-ether methods. A questionnaire for common risk factors was completed for each individual. Results: Overall, the prevalence of intestinal parasitic infections was estimated to be 125 (29%) that infected by pathogenic and non-pathogenic intestinal parasites. Various species of protozoan infections were detected: Entamoeba coli was the most common parasite (9.04%) followed by Blastocystis hominis (8.12%), and Giardia lamblia (4.64%). About 3.2% students were infected with multiple parasites. A significant association was observed between the prevalence of intestinal parasite infections with the type of accommodation (OR=1. 5; 95% CI: 1.1; 1.9), parents’ educational level (OR=1. 5; 95% CI: 1.1; 1.9) and gender (OR=1. 5; 95% CI: 1.1; 1.9). No age association was detected, and a slightly positive prevalence with increasing age was observed (p=0.66). Conclusions: These data showed intestinal parasites were slightly more prevalent than expected, that might be due to interior sources of infection in college, such as carrier students. Hence, performing periodic monitoring among students is a necessity to promote the hygiene of the students.
