RESUMO

Objetivo. Determinar la existencia de asociación entre defectos congénitos y la exposición prenatal de mujeres gestantes a PM10 en una población colombiana. Métodos. Estudio retrospectivo de casos y controles. Se incluyeron casos de madres de recién nacidos con defectos congénitos confirmados posnatalmente y controles sin defectos congénitos. La exposición a emisiones se determinó mediante disgregación temporo-espacial mediante ArcGIS® y georreferenciación mediante gvSIG, Google Earth y Google Street View®, usando estimaciones previamente publicadas y validadas para la ciudad. El análisis estadístico se realizó utilizando Jamovi-Stats Open now. Resultados . Se incluyeron un total de 101 pacientes, correspondiendo a 31 casos y 70 controles. Existió un aumento del riesgo de desarrollar defectos congénitos tras la exposición a emisiones de PM10 superiores a 2,23 Ton/año/250 m2 (OR: 8,17; IC 95%: 1.61 a 41.46; p = 0,011). Conclusiones. Existió relación entre la exposición a niveles elevados de PM10 y aumento en el riesgo de defectos congénitos en la población estudiada. Se sugiere la realización de futuras investigaciones sobre la relación entre contaminación medioambiental y eventos obstétricos adversos.


Objective: To determine the existence of an association between birth defects and prenatal exposure of pregnant women to PM10 in a Colombian population. Methods: Retrospective case-control study. Cases of mothers of newborns with postnatally confirmed congenital defects and controls without congenital defects were included. Emission exposure was determined by temporo-spatial disaggregation using ArcGIS® and georeferencing using gvSIG®, Google Earth® and Google Street View®, using previously published and validated estimates for the city. Statistical analysis was performed using Jamovi-Stats Open now®. Results: A total of 101 patients were included, corresponding to 31 cases and 70 controls. There was an increased risk of developing birth defects after exposure to PM10 emissions above 2.23 Ton/year/250m2 (OR: 8.17; 95% CI: 1.61 - 41.46; p = 0.011). Conclusions: There was a relationship between exposure to high levels of PM10 and increased risk of birth defects in the population studied. Future research on the relationship between environmental contamination and adverse obstetric events is suggested.
