Prevalence of Intestinal Parasitic Infections Among Primary School Children in Bushehr, Iran

Background: Due to their weak immune systems, contact with soil, and failure to comply with hygiene principles, the prevalence of intestinal parasitic infection is high among children. Objectives: This study was conducted to determine the prevalence of intestinal parasitic infection and the effects of various factors among elementary school children in Bushehr, Iran. Methods: Following coordination with the education office, schools were randomly selected from different areas, and fecal samples were collected from ۲۰۳ males and females students at different education levels. The samples were examined using the formalinether sedimentation technique. The data were collected via questionnaires and analyzed using SPSS ۱۸.۰ and the Chi-squared test. Results: Approximately ۲۵.۱% of the children were infected with at least one type of intestinal parasite, and ۵.۹% of them were infected with more than one species. The highest prevalence was apparent in children at education levels ۴ and ۵. There was no significant relationship between infection and parents’ education and some clinical symptoms, such as abdominal pain, loss of appetite, and nausea, but there was a significant relationship with the number of family members. Conclusions: The prevalence of intestinal parasitic infections was relatively high among the schoolchildren in this study. Since these parasites can cause anemia and dysfunctional nutrient absorption, growth, and learning among children, it is suggested that training courses be held for parents and that basic steps be taken to improve the level of hygiene in the region to prevent the transmission of these parasites.
