RESUMEN
PURPOSE: To evaluate the nutritious state in children of low social-economic class in order to look over a possible corelationship among this status and the infections caused by enteroparasites. METHODS: 103 children were submitted to a nutritions evolution and to accomplish a exam of serial samples. The method employed searched protozoan cystos, helmints eggs and larvae and it counted helmint eggs when presented through 4 different methods of diagnosis. RESULTS: The results obtained show that the poor environmental and social-economic conditions helped create a high infectious frequency caused by enteroparasites, mainly by Trichuris trichiura and Ascaris lumbricoides, among the helminthes, and Endolimax nana and Giardia lamblia, among the protozoans. light malnutrition without protein deficit was found in 93.55% and moderate malnutrition in 6.45% of the children malnutrition (30.7%). CONCLUSION: Then, it is possible to suggest that children besides bearing many parasitosis were not weth their nutritional state deeply compromised.
