Resumen
Objetivo: Investigar la prevalencia de hipertensión arterial sistémica y su asociación con la exposición prenatal al mercurio en gestantes de la región Xingu. Métodos: Estudio observacional, transversal, prospectivo realizado con 110 gestantes de 15 a 40 años. Se investigó a las usuarias sobre su perfil socioeconómico, clínico, obstétrico y la cantidad de mercurio en su cabello. Resultados: La mayoría eran exclusivamente amas de casa, casada y con estudios primarios. El 79,1% tenía una edad gestacional entre 37 y 40 semanas. El 13,6% eran primíparas, no fumaban y el 3,6% consumían alcohol. La mayoría presentaba hipertensión arterial sistémica sistólica, 4,6% diastólica y 31,8% de ambos tipos. El 99,05% tenía concentración total de mercurio en el cabello < 2µg/g y bajo consumo semanal de pescado. No se observaron asociaciones significativas entre el mercurio total y ninguna medida de presión arterial sistólica o diastólica, ni entre la hipertensión arterial sistólica y la frecuencia de consumo de pescado. Hubo una diferencia significativa en la asociación entre la hipertensión arterial diastólica y mixta y el consumo de pescado. Conclusión: Esta población presenta hipertensión arterial, bajo nivel de exposición al mercurio ambiental y bajo consumo de pescado, aunque viven en zonas potencialmente contaminadas por mercurio ambiental.
