Environmental exposure to pesticides and Amyotrophic Lateral Sclerosis in the South of Spain.

OBJECTIVE: To determine if there is a relationship between environmental exposure to pesticides and the prevalence of Amyotrophic Lateral Sclerosis (ALS) in Andalusia. METHOD: We carried out a case-control study using the logistic regression method to verify the relationship between the prevalence of ALS in the area exposed to pesticides versus the unexposed area, through the Odds Ratio statistical test. RESULTS: The study population consisted of 519 individuals diagnosed with ALS between January 2016 and December 2018 according to the CMBD (Minimum Basic Data Set) as cases. In the control group, we have 8,384,083 individuals obtained from data from the National Institute of Statistics (INE). The Odds Ratio (OR) was used as a measure of association between cases and controls, obtaining an OR between 0.76 and 1.08 for the confidence interval of the CI (95%). CONCLUSIONS: Despite the existence of various studies that suggest a possible association between environmental exposure to pesticides and the risk of Amyotrophic Lateral Sclerosis, our analysis of the Andalusian population did not find significant evidence of this association.

Objective: To determine if there is a relationship between environmental exposure to pesticides and the prevalence of Amyotrophic Lateral Sclerosis (ALS) in Andalusia. Method: We carried out a case–control study using the logistic regression method to verify the relationship between the prevalence of ALS in the area exposed to pesticides versus the unexposed area, through the Odds Ratio statistical test. Results: The study population consisted of 519 individuals diagnosed with ALS between January 2016 and December 2018 according to the CMBD (Minimum Basic Data Set) as cases. In the control group, we have 8,384,083 individuals obtained from data from the National Institute of Statistics (INE).

Objetivo: Analizar si existe una relación entre la exposición ambiental a pesticidas y la prevalencia de esclerosis lateral amiotrófica (ELA) en Andalucía. Métodos: Realizamos un estudio de casos y controles con regresión logística para esclarecer la relación entre la prevalencia de ELA en el área expuesta a pesticidas vs. el área sin exposición, mediante el cálculo de razón de probabilidades (odds ratio [OR]). Resultados: Incluimos un grupo de casos, con 519 individuos diagnosticados de ELA entre enero de 2016 y diciembre de 2018, obtenidos del conjunto mínimo básico de datos, y un grupo control con 8.384.083 individuos obtenidos de la base de datos del Instituto Nacional de Estadística. Se utilizó la OR para medir la asociación entre casos y controles, con un intervalo de confianza del 95% de 0,76-1,08. Conclusiones: A pesar de que varios estudios sugieren una posible asociación entre la exposición ambiental a pesticidas y un aumento en el riesgo de ELA, nuestro estudio sobre la población andaluza no halló datos significativos en favor de dicha hipótesis.(AU)
