Introduction: Exposure to pesticides is a known risk for human health. This paper describes the relationship between parental exposure and congenital malformations in the newborn. Objective: To study the association between exposure to pesticides and congenital malformations in neonates born in the Regional Hospital of Encarnacion, in the Department of Itapua, Paraguay. Materials and Methods: A prospective case-controlled study carried out from March to February Cases included all newborns with congenital malformations, and controls were all healthy children of the same sex born immediately thereafter.

Births outside the hospital were not counted. Exposure was considered to be any contact with agricultural chemicals, in addition to other known risk factors for congenital defects. Results: A total of 52 cases and 87 controls were analyzed. The average number of births each month was The significantly associated risk factors were: living near treated fields OR 2.

Other known risk factors for malformations did not show statistical significance. Conclusion: The results show an association between exposure to pesticides and congenital malformations. Further studies are required to confirm these findings.

Key words: Congenital malformations, agricultural chemicals, pesticide exposure. Un tercio de estos defectos pone en peligro la vida. A pesar de muchos estudios publicados sobre los pesticidas y la salud humana, permanecen profundas controversias al respecto. Algunos pesticidas en uso fueron desarrollados durante la segunda guerra mundial para ser utilizados en los combates. En el apartado de resultados, se presentan las frecuencias, tal como se llenaron las fichas.

Congenital malformations and pesticide exposure. Background : Chronic pesticide exposure is a recognized risk for human health. The frequency of congenital malformations in exposed people, can be used for epidemiological studies assessing reproductive risk secondary to toxic exposure. Material and methods : A prospective study of cases and controls. The exposure could be caused by occupational activities or residence around fumigated crops. The records of cases and controls from the surveillance carried out in the Hospital Regional de Rancagua were analyzed. This hospital is active member of a collaborative study of congenital malformations in Latin America.
