Parasitic Infections and Diagnostics

Objective: To investigate the prevalence of intestinal parasitic infections and the associated risk factors in children attending preschools located in areas with different socioeconomic and structural features in the city of Rondonópolis, State of Mato Grosso, Brazil.Methods: A cross-sectional survey was conducted between 2015 and 2016 among four-to-five years old children.Initially, urban neighborhoods with preschools were classified into five risk strata for parasitic infections, which were defined on the basis of socioeconomic and structural variables.Then, one school from each stratum was randomly chosen for data collection.After obtaining the written informed consent from parents or guardians, the children provided stool samples for examination.Interviews were conducted with parents or guardians to determine the associated risk factors.Results: Coproparasitological tests were performed on 215 (46.5%) preschoolers, and the overall prevalence was 22.8%.The occurrence of such infections increased with the increase in risk stratum of the neighborhood.Protozoa infections, mainly by Entamoeba coli (11.2%) and Giardia duodenalis (9.8%), were the most frequent.The consumption of tap water (OR = 3.56, P = 0.002), no washing of fruits and vegetables before consumption (OR = 3.44, P = 0.002), and no hand washing before eating (OR = 2.63, P = 0.004) were associated with these infections. Conclusions:The prevalence of intestinal parasites among Rondonópolis preschoolers is relevant and associated with precarious hygienic-sanitary behavior, especially in areas with poor socioeconomic and structural conditions.
