Prevalence and Risk Factors Associated with Intestinal Parasitic Infections among School Children in Gashky, West of Iran

Background Parasitic intestinal infections (IPIs) represent as the greatest cause of illnesses and diseases worldwide, especially in less developed countries. People of all ages are affected by IPIs; although, children are the most affected. This study aimed to assess prevalence and risk factors associated with IPIs among school children in West of Iran. Materials and Methods This cross-sectional study was conducted on 200 school children who selected randomly among 390 attending health care centers in Gashki, West Iran in 2016. This study we used a validated questionnaire and stool tests to gather epidemiological and disease data. The samples were examined for the presence of the parasites by direct wet mount, Lugol s iodine solution and modified formaline-ethyl acetate sedimentation methods. Chi- square and binary logistic regression procedure was applied to test the association between the variables. A p-value of Results The mean and standard deviation of children ages were 10.7±2.29 years old. The overall prevalence of the IPIs was estimated at 66 (33.0). The highest prevalence of the IPIs was related to Blastocystis 35 (17.5%), and Giardia lamblia 22 (11.0%), respectively. 18 (9.0%) out of 66 infected children had double infection. Male gender (Adjusted odds ratio (AOR): 2.20 95% Confidence Interval (CI): 1.19-4.09) was only factor significantly associated with the prevalence of the IPIs in this population. Conclusion The present study found a high rate of prevalence of parasitic intestinal infections among school children in Gashky, West of Iran. The current study highlights the importance of testing for intestinal parasites in children aged school, and emphasizes the necessity of school-based prevention and control programs.
