We analyzed the relationship between helminthes and the risk factors in 4 populations with different sociocultural conditions. We examined 700 human fecal samples coming from 1 urban (LPU), 2 outline (LPS, LPN) populations in Buenos Aires, and 1 rural population (CR) in Misiones. Surveys were also completed. Moreover, we collected canine stools and soil samples. The Ritchie, Carles Barthelemy, Fülleborn, and Kato Katz techniques were used. The prevalences of helminthes were: 25.8% in LPS, 34.7% in LPN, and 49.2% in CR. No helminthes were registered in LPU. Hookworms (71.1%) and Strongyloides stercoralis (22.2%) were recovered only in CR. Prevalences of Ascaris lumbricoides, Hymenolepis nana and Trichuris trichiura from LPN were higher than in the remaining populations. Dogs from Misiones (100%) were more parasitized than those from Buenos Aires; however urban soil samples were more polluted than the other populations. We observed that the main risk factors associated with the helminthes prevalences were the feeding and defecation practices, the overcrowding, the footwear use and the type of housing (p< 0.05).
