Introduction: Intestinal parasitic infections (IPIs) are neglected tropical diseases, even though their prevalence is high in many developing countries. The public health impact of IPIs is substantial, in particular for children due to the negative effect on growth and development. Objectives: This study examines the prevalence and risk factors of IPIs in preschool-children from at-risk neighborhoods, including those from internally displaced families. Materials andMethods: A cross-sectional study among 239 preschool-children from two vulnerable neighborhoods in Bogotá. Fecal samples were collected and microscopically examined (direct and Ritchie technique) and data regarding related factors was obtained through a questionnaire. Results: A prevalence of 26.4% for pathogenic parasites (Giardia duodenalis, Blastocystis spp, Trichuris trichiura, Ascaris lumbricoides, and Hymenolepis nana) was found. Logistic regression resulted in four risk factors: siblings ≤5 years (OR 2.33 [1.077-5.021]), stray dogs (OR 2.91 [0.867-9.767]), household members (OR 2.57 [1.155-5.706]) and child’s sex (OR 2.17 [1.022-4.615]). Discussion: IPI presence in preschool children is an important health issue in Bogotá which should be addressed. A high protozoan prevalence was found compared to helminthes. Implementing policies addressing risk factors could be a first step in decreasing IPI prevalence
