Introduction: there are about 2000 million of people infected by soil transmitted helminths worldwide, principally Ascaris lumbricoides. Poverty, lack of public services and bad hygienic practices have been associated with these infections. Objetive: explore the association between socioeconomic and demographic conditions, health practices with soil transmitted helminthes infection in La Virgen, Cundinamarca. Methods: in 2005 a simple -random sampling was carried out in children aged 1 to 15 years. Faecal samples were collected for direct examination in order to determine the soil transmitted helminths infection and other intestinal parasites. Besides, a survey was carried out amongst the persons taking care of the studied children, about the sociodemographic and economic conditions in the family group. Results: these results suggest that parents low literacy (RP: 2,39; IC 95%: 0,94-6,03) is associated with soil transmitted helminths infections as well as not having water supply (RP: 2,19; IC 95%: 0,61-7,84), having house with soil floor(RP: 5,19; IC 95%: 1,75 -15,35), not washing fruits (RP: 1,73; IC 95%: 1,04 – 2,88) and the defecation in the wilds (RP: 1,79; IC 95%: 0,98 – 3,26). Conclusion: there are still socioeconomic and demographic conditions as well as sanitary associated with the presence of intestinal parasites and especially soil transmitted helminths in this community. It’s necessary to have them in mind to make health education plans.
