fa بررسی آلودگی‌های انگلی روده‌ای در دانش آموزان مدارس ابتدایی شهر زنجان در سال 1392 کارآزمایی بالینی Clinical Trials <p><strong><em>Background and </em></strong><strong><em>Objective:</em></strong> High prevalence of parasitic infections can be the result of asymptomatic infections. A number of regular and ongoing epidemiological studies are prerequisites in order to control these infections. This study was carried out with elementary school students to achieve an overview of the spread of parasitic infections in Zanjan city, Iran.</p> <p><strong><em>Materials and Methods:</em></strong> In this cross-sectional study, using random cluster sampling, 854 of 6-12 year-old students were selected from 10 primary schools in Zanjan by three methods of direct smear, formalin-ether concentration and Scotch tape.</p> <p><strong><em>Results:</em></strong> Overall, 139 students (16.3%) were found to be infected by intestinal parasites. The protozoa Entamoeba coli (4.56%), Chilimastix mesnili (4.33%), Blastocystis hominis (3.04%), Giardia lamblia (2.34%), Iodamoeba butschlii (1.87%), Enterobius vermicularis (1.52%), Endolimax nana (0.46%), Dientamoeba fragilis (0.23%), Hymenolepis nana (0.11%), Sarcocystis (0.11%) were the most common parasite types. There was a significant difference in parasite prevalence between age and parents&rsquo; education. However, no significant difference was found with gender, family income, and residence.</p> <p><strong><em>Conclusion:</em></strong> The results indicated that the prevalence of intestinal parasitic infections in primary schools was in low level and in comparison with 1994&rsquo;s study in Zanjan city it has significantly decreased. With regard to the prevalence of intestinal parasites in study areas, improvement of health awareness among students and parents especially in the field of personal health seems necessary.</p> <p></p> <p>&nbsp;<br> &nbsp;</p> <p></p><p></p> Keywords: Intestinal parasites, Primary school student, Zanjan 121 130 http://journal.zums.ac.ir/browse.php?a_code=A-10-4-919&slc_lang=fa&sid=1 R Norouzi رحیم نوروزی 5200319475328460057382 5200319475328460057382 No Dept. of Parasitology, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran دانشگاه علوم پزشکی زنجان Abbas Ali Nourian عباسعلی نوریان nourian@zums.ac.ir 5200319475328460057383 5200319475328460057383 Yes Dept. of Parasitology, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran دانشگاه علوم پزشکی زنجان Ali Hanilo علی هانیلو 5200319475328460057384 5200319475328460057384 No Dept. of Parasitology, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, Iran دانشگاه علوم پزشکی زنجان Kourosh Kamali کوروش کمالی 5200319475328460057385 5200319475328460057385 No Dept .of Epidemiology, Faculty of Paramedical, Zanjan University of Medical Sciences, Zanjan, Iran دانشگاه علوم پزشکی زنجان
