Objectives Determining intestinal parasite prevalence and their relationship with social and demographic risk factors, hygiene procedures and sanitation in pre-school children. Material and Methods This was a cross-sectional study of a representative sample (n=220) of children aged 6 to 60 months, residing in social strata one, two and three type homes (N:1,993) from the urban area of the city of Calarcá. Both microscopic and macroscopic studies were carried out using Ritchie's test to confirm the diagnosis. Results 54.7% parasitism prevalence was found. Pathogenic parasites had the following prevalence frequencies: 36.4% Blastocystis hominis and 13% Giardia lamblia . Bivariate analysis found intestinal parasite association with lack of parasite control of domestic animals, having brothers and sisters and having received food different to milk from a baby's bottle. Anemia was studied in 209 children and 3.3% prevalence found. Low weight prevalence was 9.6% and 7.5% for obesity. Conclusions A high Blastocystis prevalence was found in this group of preschool children residing in an urban setting and having good access to sanitary services. Controlling parasites on pets should be emphasized. This group of children should be submitted to periodical coprological analysis (once a year).
